Introduce competition as a leverage tactic by stating a competitor's quote that is lower for similar functionality. Emphasize that your choice will hinge on price due to internal budget constraints. This tactic is particularly effective when you can articulate your preferences but stress financial limitations.

Push for the removal of any uplift specified in your contract renewal. You can do this by referring to the past agreement and pointing out that a price increase was unexpected, especially if your usage has remained stable. Frame this as a necessity for your budget constraints.

Negotiate to have any auto-renewal clause removed from the contract. Emphasize this as a requirement from your finance/legal team to retain control over future negotiations and flexibility in budget considerations.

If any new features or upgrades are being pushed, position your financial constraints in relation to security needs. Highlight that other vendors include similar features without extra costs, and use this as leverage in negotiations for discounts or waivers.
