Change order

A change order is a written modification to the original contract scope or price — added work, a selection upgrade, or a condition discovered on site.

Change orders should adjust both the contract price and the job's budget, with overhead and profit markup applied. Unbilled or undocumented changes (scope creep) are a top cause of margin erosion, especially on remodels with allowances and selections.
