As a SaaS buyer, you’ve likely seen a number of software pricing models, or cost structures that allow buyers to pay a variable price for use of the business app or solution.

A software-as-a-service pricing model is the cost of the product, services, and technology SaaS suppliers provide. SaaS cost can be based on a number of things, but often reflects the value that the software intends to bring to its customer. The goal of a SaaS pricing model is to balance the cost to provide the product and the customer’s success and satisfaction. Since cost and product use can vary among their customer types, it is typical for a SaaS company to offer more than one pricing model.

Get a recap of spending and deal flow in 2022, highlights of the changing SaaS buying landscape, and predictions for 2023.

With ever-growing tech stacks, procurement managers are responsible for managing many different SaaS pricing models and contracts simultaneously.

In a 2020 Gartner survey, 64 percent of customers said the pricing model was important in their SaaS purchasing decision. 

In this guide, we will help you understand what the most common SaaS pricing models are, discover the advantages and disadvantages of each, and then how to proactively work with your SaaS suppliers to align the best pricing strategies with your company’s budget, needs, and goals. 

Cost-based SaaS pricing models

Cost-based pricing is the simplest form of SaaS pricing because each product has one price point. The SaaS supplier using a cost-based approach has analyzed their expenses to provide and support the SaaS application and then has determined a profit margin on top of that. SaaS buyers seeking a cut-and-dry, straightforward approach to pricing may prefer cost-based strategies.

The most common modern cost-based SaaS pricing model is the flat-rate pricing model.

SaaS pricing model: Basecamp Business Flat-rate pricing

Flat-rate pricing

The easiest way to define flat-rate pricing is one product with one feature set at one price. You may hear it referred to as cost-plus pricing

A popular all-in-one project management SaaS supplier, Basecamp is known for its flat-rate pricing. For customers who want more than the freemium package, every feature and perk they offer is in one package with one simple monthly fee. There are usually no add-ons.

Cost transparency is one of the most important price model characteristics because it reduces the chance for sticker-shock. Simplicity and predictability are also important, as most buyers prefer a simple pricing model over a complex one. All three of these characteristics are in line with a flat-rate model.

If your SaaS stack has a pretty narrow scope of applications that do not need customizations, flat-rate pricing can be a good option. 

Advantages of flat-rate pricing

  • Simplicity and transparency for budgets
  • Low-maintenance supplier relationship
  • Simple contract management

Disadvantages of flat-rate pricing

  • Lack of package customization
  • Cost that may be higher than value
  • Less supplier engagement

Value-based SaaS pricing models

Value-based pricing models are founded on the customer's perceived value of the SaaS product. With this price approach, SaaS companies must have a solid understanding of their customers and what they perceive as value. Value-based pricing is not determined by the cost of bringing the product to market, but instead, reflects the value that it brings to customers.

The value-based approach provides benefit to SaaS buyers because suppliers using value-based pricing will often be more in-tune with their customer base. This is also beneficial for the supplier because when a customer perceives value in a product that is higher than its cost, they are often less influenced by cost.

Some of the most common value-based SaaS price models are freemium, per-user, and tiered pricing.

Freemium pricing

Freemium price models offer a free version of a SaaS application with a limited feature set. Then, to get premium features, customers must upgrade to a paid plan.

Freemium pricing should not be confused with free trial pricing or a free user pricing structure. The freemium pricing model includes a package that can be used indefinitely at no cost, with a limited set of features. A free trial often offers all features for a limited period. Paid packages may sometimes include a specified number of free users. 

Online writing assistant Grammarly uses a freemium SaaS pricing model. Subscribers can take advantage of a free subscription with limited features. Grammarly offers a premium paid subscription when end users try to use a feature not available in the free version.

SaaS pricing model: Freemium pricing

Advantages of ​​freemium pricing

  • Free option for many users
  • Simple contract management
  • Enhanced product awareness and buy-in
  • The ability to test without investing

Disadvantages of ​​freemium pricing

  • Lack of customization
  • Changes in pricing if the buyer decides to upgrade

Feature pricing

Feature-based or per-feature pricing models are usually created in feature tiers. Each tier up includes more features and more cost. Buyers seeking an “off-the-shelf” application will not pay the same price as buyers seeking a robust application full of all the bells and whistles. Feature pricing models make that possible.

Cloud-based software giant Salesforce offers a tiered feature-based pricing model, as does popular travel and expense management software provider Concur.

SaaS pricing model: Feature pricing

Advantages of feature pricing

  • Simple contract management when tier-based, if the company is using the same features for a long-term period
  • The ability to use lower tiers as a test-drive
  • The ability to only pay for the features you need

Disadvantages of feature pricing

  • Essential features may only be available in upper tiers
  • Overlapping features can cause confusion

Per-user pricing

The per-user SaaS pricing model gives buyers the flexibility to pay only for each user using the software application. 

In per-active-user pricing, customers are only charged for end-users signing into the SaaS system. In a per-user model, you'll determine the number of users and pay the price for them whether they use the system or not. 

Though per-active-user pricing is popular among buyers, it is offered less frequently by SaaS solution providers because cost changes month over month. 

Business communication platform provider Slack offers a per-active-user model combined with other models.

Per-user and per-active-user pricing

Advantages of per-user and per-active-user pricing

  • Cost savings for companies with limited users
  • Simple and transparent costs

Disadvantages of per-user and per-active-user pricing

  • End-users share logins to save costs
  • Difficult budgeting if per-active user pricing

Tiered pricing

Tiered pricing

While tiered pricing can stand alone as its own strategy, suppliers might combine it with various other SaaS pricing models. SaaS suppliers cater to different buyer personas by offering bundled feature sets. Packages with more features or more active users come with a higher price tag. Most SaaS suppliers offer some variation of a tiered pricing model. 

HubSpot uses a tiered strategy to offer starter, professional, and enterprise tiers with distinctly different pricing levels and features.

4 questions to ask sales reps about the SaaS pricing model 

While we’ve shared some of the typical pricing structures you can expect, it’s important to keep in mind that they’re not always as transparent as they seem. One way to work through this is to ask potential suppliers for four things: 

1. Can they provide a contract that fits the needs of your specific business?

Although most SaaS suppliers have standard SaaS contracts, customers may also request a custom contract when their pricing page isn’t clear. When you reach out to your SaaS supplier, describe what changes need to be made to the standard contract, and be as specific as possible.

Your SaaS supplier will then review your request and let you know if it can be accommodated. If yes, they will provide you with a revised contract that has the right pricing strategy for you to review and sign.

2. Is the timeline of 90 days to assess renewals reasonable?

You should keep an eye on your renewal dates in order to avoid getting stuck with a contract you don't want. Before the renewal date arrives, determine whether you want to renew the contract. If so, check for any updates in the contractual terms or changes in pricing. Start 90 days prior to the renewal date — this way there will be some leeway if you need time for negotiation.

3. Do they provide SKU-level pricing? 

If your supplier’s user pricing model is consistent, their monthly and annual rates can be easily broken down into line items or functionality-level costs. SKU-level pricing is a fractionated version of the different price points, which helps you understand exactly what you are paying for. If bundled SaaS pricing options lack clarity, you can ask your SaaS provider for SKU-level pricing. 

4. Do they follow an economies of scale strategy?

The economies of scale concept is all about driving the average cost of service (ACS) down by acquiring a high volume of customers. When their ACS is low, SaaS service providers can not only offer competitive pricing on their products, but also great discounts on bulk SaaS license purchases. 

Because the economies of scale model places a lot of emphasis on price effectiveness, you’re highly likely to secure a win-win deal. 

How to negotiate SaaS pricing 

Whether it's part of your initial market research or you wait until the procurement negotiation process, determining whether a supplier’s pricing model works for you is a critical piece of SaaS buying. 

To simplify, identify your company's goals and how those align with the different pricing models available. For example, you may decide that a particular SaaS pricing model may save costs, but won’t give you all the features that you need. 

Once you’ve made a SaaS purchase, it’s essential to reassess your company’s needs upon renewal. You may discover that things have changed and the price that you’re paying is no longer advantageous. It is OK to go back to your SaaS supplier at that time and discuss other options. 

Tips for negotiating your SaaS costs

Negotiating SaaS costs can be difficult, but it is possible with some preparation. You should know what benefits are offered by a SaaS provider and how they compare to their competitor. Rather than pushing your supplier to give you a low price, look at the value of the product and think about the use cases you can fulfill with it.

The negotiation process can be tough, but you need to remember that it's not personal. While it is essential to take part in the discussion, active listening can go a long way in helping you find the middle ground in a negotiation.

There may be tension with procurement negotiation, but that doesn’t mean you have to settle for less or make a hurried decision. When you come into negotiations armed with pertinent data about your software needs, you’ll be in a better position to set limits on what you’re willing to spend. Both sides may need to make concessions in order to build or maintain a healthy supplier relationship.

Taming the SaaS vortex: A Vendr Fireside Chat with Datadog's Michelle Vita

With the explosion of SaaS, staying ahead of SaaS Procurement and ensuring a lean tech stack has never been more challenging. Procurement professionals work daily to tame the “SaaS vortex” and ensure they maintain value as they add complexity and license volume to the stack. This has forced an evolution in Procurement and new approaches for professionals managing the software buying process. 

Michelle Vita is well-versed in this evolution. As a procurement professional with over a decade of building procurement processes for business, Michelle’s career has evolved from traditional procurement roles in private real estate development to high-tech roles in real estate technology and SaaS. Most recently, Michelle took the reins as Head of Procurement for cloud-scale monitoring and security firm Datadog. 

At the recent Digital Procurement World conference, Michelle took the time to sit down with Vendr’s KR Barron to talk about taming the SaaS vortex and building a supportive, sustainable procurement practice for Datadog. She shared her insights on team-building, growing an agile organization, and empowering your stakeholders. 

We’ve captured the highlights from the session below. 

How team cooperation helped Datadog tame the vortex

Michelle has spent three and a half years at Datadog evolving the Procurement team from a “department of one” into a thriving, progressive team with operational and strategic mandates. 

During that time, she’s come to believe the heart of a progressive, strategic Procurement function is its people.

“There are two types of Procurement personas now,” she explains.

“Classic, traditional procurement professionals, with a 7-step process, etc. Then there’s the new procurement professional. They’re more strategic and agile, more a jack-of-all-trades. The industry, in general, is evolving toward this model.”

These young, powerful professionals and the explosion of SaaS have brought about this new breed of procurement professionals. 

These new professionals are also changing the way their stakeholders think about SaaS. They’re empowering employees to negotiate on behalf of their company to buy the right tools, with the perspective of “buying as if you were the owner of the company.” 

Michelle describes her own team at Datadog in these terms. Her first hire came by way of an internal candidate who already understood the procurement process from the stakeholder perspective. Michelle described this agile-focused colleague as “one of the best hires I’ve ever had.” This versatility has allowed them to grow with the team, take on new projects, and execute effectively. 

Since that first hire, Procurement at Datadog has evolved into a two-pronged department, with members focused on both operations and strategy. The team includes progressive-thinking procurement and contracts experts who leverage technology to educate stakeholders, create good policy, and create a seat at the table for Procurement.

Buy with intention

The economic uncertainty of 2022 has ushered in a more measured approach to buying than in previous years. Even as SaaS has become more challenging to optimize, being strategic about your business cases and volume has a positive impact on the software budget. 

Where once the rationale was to buy “as many licenses as we can move into someday,” Michelle and Datadog stick to a strategic, “buy as you go” license approach that helps the team save money and be more conservative. Having licenses waiting on the shelf for someday “is money that goes to waste.” 

The temptation is to buy the number of licenses you’ll need for a future date, incentivized by the perceived savings of a volume discount. But, “taking advantage of a discount isn’t good if they’re just sitting on a shelf unused,” reminds Michelle. 

Instead, the team has become more focused on getting the licenses they need for the current team. Procurement has also focused on the best management of those tools, performing license audits, and ensuring proper utilization. They’ve also gotten more strategic about tier levels. Datadog assigns top-tier licenses for some power users and viewer licenses for others that are cheaper. 

Strive for agility and automation

When faced with a lack of resources—be it budget, headcount, or data— Procurement is tasked with applying agility to the procurement process. Michelle is always on the lookout for places to reduce human activity.

“I’m a huge supporter of relieving the team of administrative burdens that don’t add value.”

To do this, the Procurement team looks at the end-to-end process, identifies those processes taking up human touch and time, and automates them.

The team has turned once onerous processes into touchless processes that reduce friction in day-to-day operations. For instance, vendor follow-ups used to take up considerable time for the team. Now, those processes are controlled by Robotic Process Automation (RPA). Bots now perform a follow-up workflow for outstanding items, allowing procurement to focus on higher-level tasks.

“Agility is important, but also [means] working with our partners, establishing relationships, and using them to grow.” 

The contract process also slowed down internal progress, so the team found ways to reduce friction and remove human intervention from the process. By integrating their contract system with an e-signature tool, they can move contracts for review to Legal automatically, collect signatures, and speed up the contract execution process. 

Agility relies on partnerships, so as part of the legal contracts automation, the Procurement team worked with vendors to use internal paper for contracts. Using an internal template that is acceptable to vendors gives the legal team more control over the review process and speeds up the time to completion. 

Empower your stakeholders

Stakeholder education plays a huge role in creating a collaborative, functional relationship between procurement and the larger organization. The key, says Michelle, is to empower stakeholders with just the information they need to execute. 

The Datadog team invested time and resources in ensuring stakeholders had what they needed to learn the ropes. While the company had some resources in place, “Sometimes you need resources for various types of people since everyone learns differently.” 

The road to better stakeholder education started with a conversation. “We gathered stakeholder feedback from a survey on our processes.” The team issued an anonymous survey asking users to give their feedback about the purchasing process and the resources available to them. 

“Training kept coming up and coming up.” 

The team realized that even though resources were out there, the onboarding of those resources could be improved. “Our internal team feedback… kept coming up that people were starting [at the company] and not watching the videos.” Those conversations allowed the Procurement team to identify the issues and develop a plan. 

Automation has a part to play in the empowerment process, as well. “We wanted to empower stakeholders to do things that don’t require procurement touch.” To help stakeholders gain confidence in buying on behalf of the company, Michelle and the team implemented a guided help service for users.

Modeled on the “Clippy” office assistant featured in Microsoft Office, the procurement assistant program sits on top of the Procurement system, providing helpful pop-ups for users as they engage with the UI and perform routine tasks. If the user gets stuck or needs assistance, the assistant robot guides them through the process with a “click here” approach. This allows stakeholders to self-service needs without relying on procurement team members directly. 

Ideas such as these allow Procurement to remove itself from the areas where it doesn’t add value while still maintaining agility for the wider team. From there, they can develop stronger relationships between departments, gain a strategic seat at the table, and ensure that once they have that position, they can deliver value.

After all, “If Procurement is the Cost Savings Department, we break the trust of our internal stakeholders all the time.”

What is budget variance, and how it can impact your SaaS spend

Your team worked hard to create an accurate budget for the upcoming year. Considerable planning went into the financial model; Finance was confident in its assumptions. 

Now it’s mid-year, and your actual figures are off. Potentially really off in some places. 

What’s going on here?

Every company — small business and enterprise company alike — deals with budget variances and other FP&A challenges. In a swiftly changing economic and business environment, they’re somewhat inevitable. But you can control their occurrence and impact on the balance sheet. 

Get a recap of spending and deal flow in 2022, highlights of the changing SaaS buying landscape, and predictions for 2023.

See the 2022 SaaS buying trends.

Today we’ll look at budget variances: How they occur, what to do when you find one, and how to reduce their likelihood and impact on your business. 

First, let's fully define what a budget variance is.

What is a budget variance?

A budget variance is a difference between the budgeted amount for a specific department or project versus the actual amount.

Budget variances are a common part of the financial life of most companies. That being said, frequent or extreme variations in the budget can be disruptive to cash flow. Variances may signal a mismatch between expectations and actual results on revenue or planned spending for products and services.

Budget variances can be either positive or negative:

Positive: A positive budget variance (also called a favorable budget variance) means that your company spent less than intended on a specific budget item. There can be several reasons for a positive variance. And while a variance may not be a cause for concern, it pays to research these when they occur. Run a variance report on the business budget to look for any overestimations or changes to liabilities.

A budget variance should always be investigated, even if that variance seems like a windfall.

Negative: Most finance professionals think of this when they hear the word variance. A negative variance (an unfavorable budget variance) refers to spending over the allotted budget. There are several reasons why budget variances occur. While not every variance can be avoided, monitoring can help reduce their occurrence and impact.

How a budget variance can happen with a SaaS contract

Software contracts are also subject to the effects of variance. With a standard subscription built on an annual or monthly basis, variances are less common. Variance in a fixed contract usually happens because a department needs to add more licenses or tools after establishing budgets. But other contract structures — usage-based or drawdowns — are likely causes of unplanned SaaS spend.

5 common causes of budget variance

Budget variances aren’t always a matter of errors (though sometimes this is true). Here are the five most common sources of budget variances affecting your budgeting accuracy:

Changing economics: Shifting economic conditions is one of the most common sources of changes to actuals versus budgets. Changes in commodities prices, labor costs, overhead expenditures, and services can create big expense variances between the estimated spending and the numbers at the end of the period.

Budgeting errors: Human error does play a factor in budgeting issues. This can be a matter of underestimating actual expenses or even a simple data entry issue on an Excel sheet or a line item. Variances of this type may be positive or negative, but if they occur repeatedly, it may be time to review your budgeting process and streamline where necessary.

Pricing changes: changes to the pricing of your services or fixed assets can create a variance in a budget. For instance, if insurance premiums at renewal are higher than anticipated for a fixed asset costs have risen as a matter of expansion, variances may be the outcome. It’s important to keep an eye on planned expenditures that diverge from the original budget and make adjustments where necessary.

Process streamlining: Improvements in your operational or financial processes may create a positive budget variance. Implementing streamlined spending approval processes, for example, may result in reduced tail spend that will positively impact the budget for that.

Risk and employee fraud: One unfortunate source of budget variance is risk-based costs such as disaster recovery, legal fees, and procurement fraud. These variances are hard to predict and either and harder to avoid. The best prevention for such budget shortfalls is increased due diligence and robust financial monitoring.

5 examples of budget variance in software

Software budgets are subject to variances just like any other cost. Here are some ways your SaaS buying budget may become out of sync with the actuals.:

Usage changes

Changes in how you use a piece of software may result in fluctuating actual costs associated with that tool. For instance, increasing service level tier mid-contract to better route team or project requirements will consume more of the budget than planned. Building flexible budgets with some play for software changes can help alleviate budgeting issues at the end of the period


Usage-based contracts such as those that charge her credit or her impression may result in higher than expected spending for those tools. When establishing a contract for a usage-based tool, discussing scenarios where usage changes is important. Sometimes, the supplier is willing to work with you for anticipated increases mid-contract. A good rule of thumb is that becoming a better customer should never be more expensive.

Early drawdown

Draw-down contracts that rely on a pool of funds, service credits, or use may be subject to early renewal if usage exceeds the anticipated amount or allotment. As with overage fees, it’s important to establish the ground rules with your supplier before you sign the contract. Using more of a product should offer an advantage instead of a penalty.

Incorrect usage estimates

Both overage scenarios above are often associated with underestimating the need for a product at the point of negotiation and contract execution. Building better modeling for expected usage can help reduce the occurrence of this type of variance. Make this a point of negotiation when dealing with a new supplier for a usage-based or drawdown contract.

License/user increases

Sometimes growth requires spending. One source of budget variance is the need for more licenses or seats of a specific software tool throughout the contract. This happens when hiring cadences increase or new projects get underway. This is another point where a successfully negotiated supplier relationship can benefit when you realize your needs have changed.

How budget variances can impact your bottom line

Budget variance can be an insidious drain on revenue if left unchecked. Overages in your budget, especially those overages which cannot be tied to a product or project, must be mitigated wherever possible.

Budget issues that affect cash flow can affect your financial statements and creditworthiness as a downstream impact if ongoing problems are left unresolved. 

What to do when you notice a budget variance

Research the variance cause: granular access to data is your best ally in tracking and resolving budget variances. When you discover an issue between your budget in your actuals, take the time to dig into the numbers and establish that the variance has occurred (that it’s not the result of a data entry error or oversight) and the root cause, if any.

Plan a course of action: Once you establish that a budget variance has occurred, you need to decide how you will handle the variance going forward. There are a few possible scenarios for handling discrepancies between your budget and your actuals.

  • Increase or decrease the budget to align with new information.
  • Divert from other budget lines to satisfy a shortfall.
  • Find ways to boost actual revenue to align it with expectations.

If you find these adjustments are becoming frequent, it pays to investigate and improve budgeting or estimating criteria.

4 ways to avoid unforeseen variances in your budget

Regular review and maintenance of your budget are the best ways to avoid changes in your actuals outside budget parameters. A streamlined process and help from technology can also improve budget outcomes.

Perform budget variance analysis

Regular cost performance and budgeting review are essential to reducing or eliminating variances. Some research is a routine part of your financial cadence. For example, large variances may show up during the month and closing activities for flux analysis.

As an added precaution, quarterly budget reviews are a tried and true way of heading off variances in your budget before they can become a more significant issue. Touch base with your department heads to understand changes to the spending plan before they occur and make necessary adjustments as a proactive measure.

Perform scenario analysis

For instances where you’re budgeting parameters may change, consider running scenario analysis and creating contingencies for possible outcomes. By building a budget that can absorb a variety of outcomes, you establish more confidence in the budgeting process and smooth the path for later analysis.

Consider rolling budgets

If your industry or business is subject to variable costs, seasonality issues, or other changes, consider moving away from a static budget. Rolling budgets, which are adjusted monthly or quarterly, may give your financial reporting the flexibility it needs for more accurate, agile financial planning.

Track usage

Tracking software usage, especially in usage-based or drawdown SaaS pricing models, can help you avoid overages in your software spending before they get out of hand. Create regular calendar events to check usage numbers or set up notifications within your platform that can alert you to changes between planned and actual usage. The small step will translate to big savings and cost avoidance if your project plans or scope of work changes.

The 4 types of purchase orders you’ll create when buying software

Planning procurement activities — whether for supplies, products, services, or software — requires a high level of visibility. The process gets easier by documenting planned purchases to the best of your ability. Department heads will know what purchases are on the horizon, IT can plan for capacity and implementation, Finance can plan spending more accurately, and accounting can lay the groundwork for a smooth end-to-end purchasing process. 

One way to achieve all these objectives is to streamline the purchase order process. You ensure everyone knows the game plan by documenting purchase information completely (and in advance). 

But what’s the best way to plan if you don’t have all the information? As it turns out, the structure of your purchase order can help show what you know and leave room for future planning. 

Let’s look at the different types of purchase orders you can use for purchasing software, and how to use them most effectively. 

What is a purchase order?

A purchase order form is a standardized form a buyer transmits to a supplier. The purpose of the purchase order is to outline the requirements and necessary information for placing an order and having it filled. Purchase orders are standard practice for businesses buying supplies, goods, and software from their suppliers. The purchase order also serves as a record for tracking and confirming accurate and timely delivery of purchases.

When to create a software purchase order

The purchase order process begins after the evaluation and selection of a supplier. It represents the beginning of the purchase portion of the procurement process, after any needed sourcing activities. 

Most often, a purchase requisition precedes the purchase order. This initial document (sometimes called an intake form) outlines the parameters of the business need, any requirements the solution must meet, and any preliminary evaluation the stakeholder has conducted. The information from the purchase req serves as the basis for completing the final purchase order before transmission. 

The requisition also creates a second data source for checking the accuracy of orders once the products, materials, or software licenses come in. Accounts payable checks the purchase requisition, purchase order, and invoice for parity in a three-way matching process. This process ensures compliance with delivery terms, date of delivery, the quantity of items ordered, etc. It is one component of ensuring legal protection, as it serves as a source of truth for the outcome of a supplier agreement. 

When you know exactly what you need from a selected supplier, you can create a purchase order for immediate or future use. Depending on the timing and quantity of the purchase, you may create one of four common purchase order types: standard PO, planned PO, blanket PO, or contract PO. More on those next. 

The 4 types of software purchase orders and when to use them

While standard POs are most common for the purchasing process, there are several ways to structure a purchase order. The type of PO you use will depend on the details and timeline of your purchase. Selecting the right type of purchase order structure helps smooth the procurement process and aids budgeting and planning from the accounting side. Pre-planning purchases through the right purchase order allows finance to ensure the cash will be available when needed.

Standard purchase orders (SPO)

The Standard PO (aka a “regular purchase order”) is one most buyers are familiar with. Standard purchase orders represent the intent to complete one transaction with a specific product type, quality of items, and quantity. The purchase order should outline all the necessary information for completing the transaction. Standard purchase orders are often used for a one-off purchase. 

For software purchases, a buyer may need a set number of licenses for the company or department. For instance, ten seats of a specific accounting software solution for everyone in the AP department. In this case, they would order the specific number of licenses needed to set everyone up with their own instance of the software. 

Planned purchase orders (PPO)

The second common type of purchase order is that planned orders are similar to standard ones but for a future, undetermined delivery date. These purchase orders are developed with all the details of standard orders. The money for these is placed in a reserve called an encumbrance) so the money will be available when it’s time to place the order. Once it’s time to transmit and fulfill, accounting performs a release of the funds and completes the purchase. 

Planned purchase orders are ideal for purchases that are made on a semi-regular basis. One example is office consumables like coffee and tea. The purchasing department estimates what you’ll need to use based on previous purchases and timeframes. They then create a series of orders and release them as necessary (for instance, when the admin reports they’re down to the last few boxes). Planned purchase orders are handly when the order details are the same, but the exact consumption period isn’t known. 

One example of software purchasing on a planned purchase order: A development team will need 30 licenses of a popular development tracking tool for an upcoming project. The project is slated to kick off in the year's second half,  but the exact date is unknown. In this case, the team can encumber funds within the project budget and create the planned order during the planning phase. When it’s time to implement the tracking software, AP releases the funds and completes the purchase. 

Blanket purchase orders (BPO)

When you know you need an item continually, but you’re unsure of how many, a blanket purchase order can reduce redundant work and make the procurement process smoother. The information stays the same in this case, but the quantity and timeframe are unknown. Printer paper is a great example because its usage fluctuates based on the headcount in the office and the types of projects happening at a given time. With a blanket order, the release happens when the supplies run low, and the quantity is updated based on expected use for the next interval (whether a month, a quarter, etc.) 

Blanket orders may present backorder issues for the supplier if the quantity greatly exceeds expectations. For this reason, blanket orders come with a safeguard for the supplier: they outline a maximum quantity for a single purchase. This ensures the buyer can plan SaaS spending and get what they need (within reason) without creating inventory management issues for a supplier trying to fulfill orders for many customers at a specific period of time. 

In purchasing software, the team may need to requisition communication tools to meet the expected headcount for each hiring sprint. The exact timing of the orders is unknown, and the number of licenses may change depending on the hiring activity. The team can rely on receiving a certain number of licenses even if there is some fluctuation in the headcount. 

Contract purchase orders (CPO)

A contract purchase order has the least detail but still sets up the basic parameters of the purchase for when needed. It's essentially a promise of future orders, and an outline of the terms and conditions each party will adhere to once those POs come to fruition. A contract purchase order is not a binding contract until accepted by the seller.  

Contract purchase orders don’t contain the specific delivery schedule, quantity, or item information. They may have mutually decided timeframes for purchase (for instance, a quarterly estimate). In software, these purchase orders may come in handy when working with a software reseller. They outline the necessary details for transactions but leave the specifics for a future date when more information is available. 

What to include in every SaaS purchase order

Every purchase order — whether standard, planned, blanket, or contract — should offer the baseline details to complete the purchase. When developing a purchase order to buy SaaS software, include the following information for your procurement and supplier-side stakeholders:

Supplier information

Once known, detail the supplier information, including any details necessary to transmit the purchase order and pay the resulting invoice. By outlining the necessary information for the entire purchase process, you reduce back-and-forth communication and ensure quick delivery/implementation and payment of software. 

Tier/service specs

If known, outline the service or tier level information for the products you’re purchasing. By being more specific on the purchase order, it's easier for accounting and receiving stakeholders to verify that the desired products were ordered and delivered. 

Payment details

If the suppler has specific payment terms (for instance, early payment discounts, preferred payment forms, volume order discounts) outline these in the PO to ensure accurate billing and timely payment.
