Presenting competition as an alternative has proven effective in negotiations. Bring up offers from competitors that have a lower cost or additional functionalities that the current vendor doesn't provide, emphasizing the need to secure a better deal based on what others are offering.
Negotiate to have the uplift removed based on your projected budget constraints. Reiterate that most suppliers do not impose uplifts under similar conditions, and emphasize that a flat renewal cost should be the standard when continuing the partnership.
Request the removal of auto-renewal clauses to maintain flexibility in your contract. Emphasizing this requirement can help open up negotiation opportunities, ensuring you can reassess the agreement before it automatically renews.
If the vendor is introducing new pricing models or features, communicate that while you recognize their importance, budget constraints require that these be offered at no additional premium. Illustrate that competitive offerings include similar features without extra costs.
Offer to provide a case study or act as a reference, contingent upon receiving better pricing. This approach can strengthen your position as a valued customer and encourage the vendor to consider your request more favorably.
