A contract clause requiring the client to pay for a minimum volume of services or materials, whether used or not.

A formal written amendment to an existing contract that modifies scope, cost, or schedule. Subcontractors should never perform out-of-scope work without a signed change order. Undocumented changes are a leading cause of unpaid invoices and disputes.
