Why change orders protect your margin

Every contractor has been there. The client asks for one more thing. You say yes on site. Weeks later, the invoice does not match what they expected—and your margin takes the hit.

Scope creep costs real money

Without a written change order, extra work becomes free work. Specialty trades feel this constantly: an extra primer coat, a soft subfloor, a deck repair under the shingles. Each “while you are here” request looks small until the job closes underwater.

A change order documents what changed, what it costs, and who approved it. That single habit turns verbal extras into sold scope.

What a good contractor change order includes

Description of the change, price impact, schedule impact if any, and a dated approval from the client. Keep it simple and send it before the work starts whenever you can. Digital approval links make that easier than chasing paper on a job site.

Connect change orders to estimate versions

Change orders should reference the accepted estimate baseline. If you overwrite quotes in a spreadsheet, nobody can prove which number the change applies to. Versioned estimates keep that baseline locked.

Connect change orders to your job budget

When a change order is approved, it should update the live job budget automatically. Sold price and cost both move. That way you always know what the job is actually making—including extras—not just the original bid.
