Introduce competition by informing them of lower quotes from alternative vendors. This tactic emphasizes that you are actively exploring more affordable options, which can create leverage during pricing discussions.

Negotiate to remove auto-renewal features from the contract. This can allow for enhanced flexibility and the opportunity to evaluate the product's value on an annual basis without automatic commitments.

Anchor your negotiation around budget requirements which do not accommodate large uplifts in pricing. This tactic pressures the vendor to keep costs reasonable when they are trying to increase rates due to features or usage expansion.

Leverage the addition of more users to negotiate a lower per-user cost. This can help in reducing the overall pricing as volume growth typically warrants discounts.

Propose your participation as a case study or as a reference in exchange for better pricing or favorable terms. This can create value for the vendor while costing you nothing extra.
