How to Write a Change Order a Customer Will Approve

You opened the wall and the job changed. Rot, old wiring, a shutoff nobody mentioned, a customer who now wants the other fixture. If you keep working on a verbal "yeah, go ahead," you are hoping they remember the price the same way you do. They often do not. A change order is the short document that keeps the extra work from becoming a free extra.

Stop before you buy the extra materials

The moment to write it is when you find the change, not when you invoice at the end. Tell the customer what you found, what it will take to fix, and what it adds. Then wait for a yes. Buying the parts first and asking second is how a reasonable extra turns into an argument.

What the change order needs

It does not need legal language. It needs enough detail that someone who was not standing there can understand it a month from now.

• What changed. One or two sentences. "Supply line in the wall is corroded and needs to be replaced," not "extra work."
• Labor and materials, separate. So the customer can see where the number came from.
• The added amount. A single total for this change, on top of the original job.
• A photo, when it helps. The open wall, the failed part, the condition you could not have known about from the estimate.

Photos matter most when the change is something they cannot see once you close it up. A picture of the problem is harder to dispute than a line that says "additional repairs."

Get the yes in writing

A text that says "ok" is better than nothing. A clear approve or decline on the change itself is better than a text, because it stays attached to the job and the amount. If they decline, you stop that extra work. If they approve, the amount belongs on the bill they already have, not on a second invoice you have to explain later.

Do not fold the change into the original price quietly. Customers notice when the final number does not match what they approved. Showing the original job and the approved extra side by side is what makes the new total feel fair.

Keep drafts off the customer

A half-written change order is for you, not for them. Send it when the description and the price are ready. A blank or guessed number trains them to ignore the next one.

In EZ Invoices you add the change order on the invoice: what changed, labor, materials, and photos. The customer sees it on the pay page and can approve or decline. An approval adds that amount to the balance due, including the next unpaid stage if the job is billed in milestones. A draft stays off the customer page until you send it.
