Negotiate to remove any auto-renewal clauses in the contract. This gives you control over future renewals and allows for time to evaluate performance and cost effectively before committing to another term.
Engage in discussions to reduce or remove the proposed uplift cost. Emphasizing that it was not part of the previous contract terms can help leverage a better deal for renewal.
Request to carry over any current one-time discounts into future terms, if applicable. Clarify that these discounts were not explicitly stated as one-time only in the previous agreement, allowing for potential savings.
