Minimum purchase commitment

A promise to buy a set quantity or spend a set amount over a period, with a payment owed for any shortfall even if you buy less.

What it means

A minimum purchase commitment requires the buyer to buy a certain volume or spend a certain amount during a period, such as a year. In a take or pay arrangement, the buyer must either take delivery of the minimum quantity or pay for it anyway. These terms are common in supply, manufacturing, logistics, energy, and cloud services contracts.

In return, the buyer usually gets a lower unit price, guaranteed capacity, or exclusivity. A small cosmetics brand might commit to buying 50,000 bottles a year from a packaging supplier at a discount. If sales slow and it needs only 30,000, it may still owe for the missing 20,000, either at full price or through a shortfall fee.

These commitments favor the seller, who gets predictable revenue to justify investment. The main risk for the buyer is committing on optimistic forecasts. Buyers sometimes argue that a shortfall payment is an unenforceable penalty, but courts often treat take or pay terms as a pricing arrangement rather than a remedy for breach, and the analysis varies by jurisdiction.

What to watch for

  1. Check how the minimum is measured, whether monthly, quarterly, or yearly, and whether excess purchases in one period offset shortfalls in another.
  2. See how any shortfall is calculated and whether it is payable at full price or a reduced rate.
  3. Look for relief if the seller fails to deliver, raises prices, or a force majeure event limits your ability to buy.
  4. Confirm whether the commitment continues through renewals and what you owe on early termination.

Example clause

Buyer will purchase at least 50,000 Units in each Contract Year. If Buyer’s purchases in a Contract Year fall below that amount, Buyer will pay Supplier, within 30 days after the end of that year, a shortfall fee of $0.40 for each Unit below the minimum.

If you buy fewer units than promised, you pay a per-unit fee on the difference at year-end.
