Minimum Commitment

A minimum commitment — also called a committed spend, commit, or minimum volume — is a contractual floor: the customer agrees to buy at least a stated amount of a product over a term, and owes it whether or not the amount is consumed. In exchange the vendor grants a lower unit rate, better payment terms, or access to features and support tiers reserved for committed accounts. The structure is common wherever billing is metered, which now includes most AI tooling: you commit to a volume of credits, tokens, API calls, records or minutes for the year, and pay a per-unit price below the pay-as-you-go rate. Minimum commitments are the main lever a buyer has to lower unit costs, and the main way a buyer gets stuck. The failure mode is forecasting. Commit high on the strength of an optimistic roadmap, ship the feature two quarters late, and you have paid full price for volume you never used — the discount is retroactively worthless, because your effective rate is the commitment divided by actual consumption, not the headline per-unit figure. Always compute that effective rate against a pessimistic usage case before signing. The terms that matter are whether unused volume rolls over into the next period or expires, whether you can draw down the commitment across multiple products in the vendor's catalogue or only the one you signed for, what the rate is for consumption above the commit, and whether the commitment ramps across the term instead of applying in full from day one. Ask what happens if you exceed the commit early: some contracts simply bill overage at list, others let you convert to a larger commitment mid-term at the discounted rate, which is materially cheaper if your usage really is growing.
