Change Order Clause
Also called: Change Control Process · Scope Change Clause
A change order clause defines the process for modifying a project's scope, timeline, or price after a contract is signed — requiring written agreement before new work begins. Without it, scope changes happen informally over email, and disputes about what was actually agreed become common.
In more detail
The core problem this clause solves: scope creep. Without a formal change process, a client's casual "can you also add..." request can turn into substantial unpaid extra work, because there was never a clear point where the original scope ended and a new, billable request began.
A working change order process requires the requesting party to describe the change, the provider to quote additional time and cost, and both parties to sign off in writing before the new work starts — turning an ambiguous conversation into a documented, billable amendment.
The clause should also address what happens if the parties can't agree on a change order's terms — whether the original contract continues unaffected, or whether unresolved change requests can trigger broader dispute or termination provisions.
A client asks a development agency to add a feature not included in the original scope of work. Under the change order clause, the agency provides a written quote for the additional time and cost, and work only begins once the client signs off — protecting both sides from a scope dispute later.
