Introduce competition by highlighting that you've received lower quotes or better value from competitors. This tactic leads to better negotiation outcomes as it creates a sense of urgency for your current vendor to remain competitive. You should emphasize the differences in costs and value additions to leverage negotiations effectively.

Utilize your existing budget that anticipated a lower rate increase and challenge any unexpected uplifts during the renewal process. Focus on established relationships and previous service levels that justify a removal or reduction of any proposed uplift based on your organization's spending growth.

Ensure your usage of the product aligns with what is under contract. Highlight any instances of underutilization to negotiate for better pricing or terms. Request reporting from your vendor on usage metrics to ensure leverage in discussing rates that reflect current needs.

Negotiate the removal of auto-renew options in your contract to maintain flexibility in the future. Emphasize that your finance team requires such adjustments to comply with their purchasing guidelines, and ensure it's a critical point in your negotiation.

If you plan to increase the number of users, emphasize economies of scale to negotiate a better rate per user. Present the growth to the vendor as an opportunity for long-term partnership that should reflect lower pricing due to increased volume.
