Exact wording
Change order wording: four sentences that hold up on invoice day.
Most change orders fail at the wording. Too vague and the customer can later claim they approved something smaller. Too legal and it never gets sent, because nobody drafts contract language standing in a hallway. Wording that works is short, specific, and structured the same way every time.
Direct answer
Effective change order wording has four parts: name the added work specifically, state that it is outside the original quote and why, give the price for that work alone, and ask for a written approval before the work begins. Each part exists to close off a specific argument later.
01Workflow
The four-part structure
- 1
Name the work: specific enough that it cannot be confused with the original scope.
- 2
Anchor it outside the quote: say why it is extra, in one clause.
- 3
Price it alone: the cost of this change, not a new job total.
- 4
Ask for written approval before starting: a reply, a signature, anything in writing.
02Practical notes
What matters in the field.
Every sentence closes off a future argument.
Naming the work kills 'I thought you meant the small one.' Anchoring it outside the quote kills 'I assumed that was included.' Pricing it alone kills disputes about what the number covered. Approval-before-work kills 'I never agreed to that.' If a dispute stings on invoice day, the missing sentence is usually one of these four.
Specificity is the whole game.
'Additional electrical work - $300' invites an argument. 'Move three kitchen outlets up 6 inches to clear the new backsplash - $281' does not. Numbers, locations, and counts make the record self-explaining months later.
The same wording works in every format.
The four parts fit a text message, an emailed PDF, or a printed ticket with a signature line. Small change, text approval. Bigger change or discovered damage, signed PDF with photos. The structure does not change - only the formality around it.
Write it before the work, every time.
Wording sent after the work is done is an invoice justification, not a change order. The same sentences carry completely different weight depending on whether they arrive before or after the labor. Before, they are an offer the customer accepts. After, they are a bill the customer inspects.

Example
Copy-ready change order wording
While opening the wall for the shower valve, we found the drain line is corroded and needs replacement - this is outside the original quote, which assumed the existing drain was serviceable.
Replacing the section of drain line is $340 for labor and materials.
Please reply 'approved' and we'll take care of it today before closing the wall back up.
04FAQ
Common questions.
Do I need legal language for a change order to count?
No. A dated written record showing the specific work, the price, and the customer's written agreement is what matters in a small-job dispute. Plain language is actually stronger, because it proves the customer understood what they approved.
What if the customer approves verbally on site?
Follow it with a one-line text immediately: 'Confirming the extra work we discussed - [work] for [price], per your OK just now.' A confirmation the customer does not correct is far better evidence than an unrecorded conversation.
How is this different from just quoting the extra work?
A quote describes work you might do. Change order wording explicitly links the new work to an existing job and existing quote, which is what prevents it from being absorbed into 'what I already paid for.'
