By presenting other competitors that offer comparable functionalities at lower prices, you can leverage their proposal to encourage Quiq to lower their pricing. Make sure to highlight specific competitors' offers and articulate how this affects your decision-making process regarding renewal.
Since Quiq's offer includes potential uplift, you should negotiate to have the uplift removed or reduced. When presenting your case, reference your previous budgeting and show that industry standards frequently do not include uplifts.
Given you may be overusing services, address the topic of overage charges in your renewal conversation and seek to have them waived. This can often be a point of negotiation, especially if you've demonstrated growth or high utilization.
If you are uncomfortable with auto-renewals, request to have this clause removed from your agreement. Emphasizing finance team guidelines can aid in this negotiation.
Offering to participate in references or case studies can serve as a value add to Quiq that they may reciprocate in the form of better pricing or terms. Highlight that this can increase their business credibility.
