In the current business environment, the importance of efficient and accurate invoice processing cannot be overstated. Handling invoices is a crucial part of the accounts payable function that involves receiving, recording, and paying bills from suppliers.

Unfortunately, traditional manual methods of managing invoices are time-consuming, prone to human error, and can cause delays in payments, resulting in strained supplier relationships. Invoice automation provides a solution to these problems, offering businesses a more effective way to manage their invoicing process.


What is invoice automation?

Invoice automation is a technology-enabled approach for managing the invoicing process in an organization. The main goal of this type of automation is to reduce or eliminate manual interventions in invoice processing, thereby increasing efficiency, accuracy, and cost-effectiveness.

The automation software uses technologies such as optical character recognition (OCR), machine learning (ML), and artificial intelligence (AI) to capture, process, and store invoice data automatically. It can extract pertinent information from incoming invoices, regardless of their format or source, and input it into the relevant systems for processing and payment.


The process of invoice automation

So how exactly does invoice automation work? Let's break it down into the fundamental steps:

Invoice capture

This is the entry point of the invoice into your business's financial system. Traditional methods require a staff member to manually enter the details of an invoice into the system, which is time-consuming and prone to human error, especially when dealing with large volumes of invoices. Invoice automation streamlines this process—the software is capable of capturing invoice data from a multitude of sources, regardless of whether the invoices are in paper or electronic formats.

The software leverages OCR technology to scan paper invoices, converting them into a digital format and extracting crucial information such as supplier details, invoice amount, date, and line item details. For electronic invoices, the software can automatically parse the necessary data from the document.

Data extraction and validation

After the invoice data has been captured, the software then proceeds to extract relevant information. This typically includes details like the supplier's name, invoice number, invoice date, line item details, and the total amount. The accuracy of this data extraction is critical for the subsequent steps in the process, hence the use of technologies like OCR, ML, and AI to ensure precision and consistency.

Following data extraction, the software then validates this information against existing company data, such as purchase orders and receipts. This validation process is vital in preventing duplicate payments, ensuring that the invoiced amount matches the purchase order, and confirming the receipt of the goods or services.

Invoice approval

After validation, the invoice is then routed for approval. The approval process in an automated system is defined by pre-established rules and workflows, allowing for a consistent and efficient procedure. For instance, invoices below a certain amount may be approved automatically, while larger invoices could require manual approval by a manager. Some sophisticated automation systems are capable of automatically matching invoices with corresponding purchase orders and receipts. If the documents match, the invoice can be approved with no human intervention needed.

Payment processing

Upon approval of the invoice, it's then processed for payment. An integrated invoice automation system can seamlessly communicate with the company's payment processing system. This facilitates a smooth transition from invoice approval to payment execution, reducing the time required to pay suppliers and potentially improving supplier relationships.

Record keeping and reporting

Once the payment is processed, the invoice data doesn't just disappear. The automation software archives this data, creating a traceable audit trail for future reference. This historical data is valuable not only for audit purposes but also for deriving insights about the company's spending patterns, supplier performance, and process efficiency. The system can generate reports that provide visibility into various aspects of invoice processing, such as processing speed, bottlenecks, supplier payment terms, and more.

The value of invoice automation lies in its ability to seamlessly integrate these steps, creating a streamlined, efficient, and largely hands-off approach to managing supplier invoices. This not only minimizes the potential for human error but also significantly reduces the time and resources required to process invoices, allowing businesses to focus on their core operations.

Key features to look for in an invoice automation system

When choosing an invoice automation solution for your business, there are several key features to look for:

Ease of integration

One of the first and most important things to consider is how well the invoice automation solution integrates with your existing systems. This includes your ERP, accounting software, payment processing systems, and any other software you use to manage your finances. A good invoice automation solution should be able to smoothly integrate with these systems, ensuring seamless data transfer between them and eliminating the need for manual data entry or importing and exporting data between different software. An integrated system also helps maintain data consistency across your software ecosystem.

Multi-channel invoice capture

Invoices come in many forms and from various sources. Some vendors might send paper invoices, others might email PDFs, while others might use electronic invoice formats. Therefore, a robust invoice automation solution should be capable of capturing invoices from all these sources and in all these formats. This includes the ability to scan and digitize paper invoices, parse PDF invoices, and process electronic invoices.

Intelligent data extraction and validation

Once the invoices are captured, the system should be able to accurately and efficiently extract the necessary information. This is where technologies like OCR, ML, and AI come into play. OCR can convert different types of documents, including scanned paper documents and PDFs, into editable and searchable data. ML and AI, on the other hand, can be used to train the system to recognize and extract relevant information, such as invoice numbers, dates, line item details, and total amounts. The system should also validate this data against your existing records to ensure accuracy and consistency.

Automated approval workflows

The ability to set up custom approval workflows is another vital feature of an invoice automation solution. This enables you to establish predefined rules for invoice approvals. For example, you might set rules based on invoice amounts, with smaller invoices being approved automatically and larger ones requiring manual approval. An efficient approval workflow not only speeds up the invoice processing time but also reduces the chance of human errors and oversights.

Reporting and analytics

The ability to generate comprehensive reports and analytics is essential in any invoice automation solution. This feature provides visibility into your invoice processing activities, helping you track your performance over time. It can also offer valuable insights into your spending patterns, identify potential bottlenecks in your invoice processing, and help you monitor key metrics like processing time and cost per invoice. These insights can inform strategic decisions and drive process improvements.


As your business grows, you'll inevitably need to process more invoices. The invoice automation solution you choose should be able to scale with your business, handling increased volumes of invoices without compromising on performance or efficiency. Scalability also applies to accommodating more complex invoice processing scenarios as your business operations evolve.

Security and compliance

Last but certainly not least, security and compliance are critical considerations. Invoices contain sensitive information, and you need to ensure that this data is stored and processed securely. Look for a solution that offers robust security features, such as data encryption, user access controls, and audit logs. The solution should also help your business comply with relevant financial regulations and standards.

By focusing on these features when evaluating invoice automation solutions, you can ensure that you choose a system that not only streamlines your invoice processing but also adds value to your business in the long run.
