What is a change order?
A change order is any approved change to the original scope of work. It usually adds labor, materials, time, or coordination that was not part of the first price.
Why change orders are often underpriced
Contractors often treat change orders like small add-ons and price them quickly. That usually misses supervision, disruption, procurement time, and the fact that last-minute changes are rarely as efficient as the base scope.
Why margin matters here
Margin tells you how much of the final selling price remains after cost is covered. If you price from markup when you meant margin, the change order can look profitable while still shrinking the job's actual profit.
