Given the competitive landscape, leverage any price quotes from competitors to drive down the pricing or terms. Present them as viable alternatives during negotiations, making it clear that budget constraints are leading you to consider these other options.
In negotiations, highlight that with the current usage and performance, a price increase (uplift) is not justified. Base this on your previous contract terms and emphasize the current financial expectations, which do not account for any uplift. Use this as leverage to secure a more favorable agreement.
If there are concerns about ROI or if the current metrics aren't meeting expectations, emphasize the requirement for a month-to-month or short-term commitment. This tactic allows for reassessment after a brief period to determine if continued engagement is beneficial.
Insist on removing auto-renewal clauses from the contract as a prerequisite for moving forward. Highlight that this aligns with current finance/legal requirements and it will allow for separate negotiations in the future. This gives you control over future engagements and deadlines.
Offer to participate as a reference or in case studies as part of the negotiation. This relationship-building tactic can help in discussions for price reductions, as you're adding marketing value to their organization.
