In this segment, Lara Guevara advises founders working with third‑party logistics providers (3PLs) to negotiate three concrete contract provisions before peak season rates take effect. First, request a percentage ceiling—a clear cap on how much the storage rate can increase during peak periods. Second, require advance written notice of any rate increase, specifying the number of days the provider must give before the change becomes effective. Third, define a precise effective date in the contract rather than vague terms like “peak season,” which can be interpreted differently by each party. Guevara notes that if a 3PL pushes back on these requests, it reveals the future flexibility of the relationship, but she observes that most providers will accommodate reasonable, written asks, preferring to avoid billing disputes later in the year.

A percentage ceiling, a specific cap on how far the storage rate can rise during peak, a number not will be reasonable. Advance notice, any increase communicated in writing with a stated number of days before it takes effect. And a precise effective date written into the contract, not peak season, which you and your TPL will define differently at exactly the moment it matters. If they push back on all 3, that's information about how the relationship goes next time you need flexibility. But in my experience, a specific, reasonable, written ask well before the trigger date gets accommodated more often than founders expect. Most GPLs would rather agree a fair cap now than a fight in a bills dispute in November.
