Invoice dispute

A disagreement between an agency and a client over whether a billed amount is owed, often triggered by disagreement over whether specific work was in scope.

Example

A client disputes a $2,400 line item on an invoice, arguing the work was a normal revision rather than a billable out-of-scope addition — the agency points to the signed change order as evidence it was pre-approved.

Why it matters for agencies

Invoice disputes over scope are almost always resolved (or avoided) by whatever documentation exists from before the work started. A signed change order settles the question quickly; an informal Slack message or verbal agreement leaves it much more open to dispute.
