Change order: what it means

Glossary term. Reviewed 2026-10-07. Process: Quotes and estimates.

DefinitionA change order is a written amendment that records a change to the scope, price or schedule of work the customer already approved. It captures what is being added or removed, what it costs, and that the customer agreed, so the final invoice matches what was authorized.

How it works in a service business

Jobs change once they start. A homeowner adds a second bathroom to the cleaning, or the plumber finds rotten wood nobody could see. Without a change order, those additions become arguments at invoice time. With one, everyone has agreed in advance. The tradeoff is friction in the moment: stopping to document a small add-on can feel pushy. A common mistake is a verbal okay on site, which is forgotten or disputed later. Make it quick: describe the change, give the price difference, and have the customer approve it by signature or message before the extra work begins. Keep the original quote visible so the total is easy to follow.

Example

Midway through a kitchen refresh, the customer asks for new cabinet pulls. The contractor sends a short change order with the added cost, and the customer approves it on a phone.
