How to Write a Change Order That Gets Approved
A change order needs five things: what changed and why, what it costs, what it does to the schedule, a photo where the customer can't see the condition themselves, and a signature or written reply approving it. Send it the moment you find the issue, before doing the work, and never continue on a verbal yes — a text reply saying "approved" is enough, but something in writing is not optional.
Five things, no more
A change order that gets approved contains:
- What changed — the condition found, plainly described
- Why — what it prevents or why the original scope can’t proceed
- What it costs — from a rate agreed at signing, where possible
- Schedule impact — days added, if any
- Approval — a signature or a written reply, dated
Anything longer than that starts to read like a negotiation, so keep it to about a screen.
Send it from the job, not from the truck at night
The customer’s right there or easy to reach, the wall’s open, and the problem is sitting in plain sight. A photo and a number sent within the hour gets approved way more often than the same request raised after everyone’s gone home and had time to think it over.
The photo is the argument
Most change orders describe something the customer can’t actually see — inside a wall, under a house, behind old siding, beneath a slab. The picture does the persuading; your paragraph is really just there to explain what they’re looking at.
Price from a rate you already agreed
This is the whole reason to put as-found rates on the original estimate. “Rotten joist repair, $180 each, as quoted” is just arithmetic at that point. A number you invent mid-job, with the customer already committed, feels like leverage even when it isn’t — so don’t put yourself in that spot.
Never continue on a verbal yes
A homeowner who said “just do it” in the driveway will remember that conversation differently once the invoice shows up. There’s nothing awkward about asking for a text — send the summary, ask them to reply “approved,” and keep going.
Label them on the final invoice
Change orders shown as separate lines with their approval dates head off the worst conversation in residential work: a final invoice that’s bigger than the contract price with no explanation attached. Labeled and dated, the total explains itself and nobody has to ask.
Say no sometimes
Not every discovery needs solving today. “This should be addressed, here’s the price, it’s not urgent” builds more trust than trying to upsell everything you find. It also makes the change orders you do insist on land a lot more credibly.
Frequently asked questions
Does a text message count as approval?
Yes, for most residential work. What matters is that it's written, dated, and clearly refers to a specific priced change — 'approved' in reply to a message showing the photo and the number is far stronger than a signature on a form nobody read.
What if the customer refuses the change order?
Then you stop at the boundary of the original scope and document why. Some customers genuinely can't afford it — finishing the agreed work and leaving the rest quoted is a legitimate outcome, and infinitely better than doing it unpaid and resenting it.
Should I bill change orders separately or add them to the final invoice?
Separately, or at minimum as clearly labeled lines with their approval dates. A final invoice larger than the contract price is the single most common trigger for a payment fight in residential work — labeling removes the surprise.
How fast should I send one?
Immediately, from the job. The customer is already engaged, the evidence is in front of you, and a same-hour photo plus number gets approved far more often than one raised at the end of the day.
