How to Write a Change Order (So You Get Paid for the Extra Work, Not Stiffed for It)

If you've ever been halfway through a job and the customer goes "oh, and while you're in there, can you just..." then this one's for you.

That sentence has eaten more profit out of small shops than any cheap competitor ever will. Not because the extra work is hard, but because nobody wrote it down, nobody priced it, and at the end of the job there's a fight about whether it was "included." A change order fixes that. It's just a short written note that says what's being added, what it costs, and that the customer okayed it before you did the work.

Sounds formal. It isn't. A good change order can be a text message. The point is not the paperwork, the point is that the price and the yes happened before the work, not after.

What actually counts as a change

A change is anything that wasn't in the original quote. Customer wants a different tile than what you priced. They added a second coat. The wall opened up and there's rot you have to deal with. They asked for an extra outlet. None of that was in the number you gave them, so none of it is free.

The mistake guys make is deciding in their head that something is "small enough" to just throw in. Once or twice, fine, that's goodwill. But a job is death by a thousand little favors. Each one feels too small to bring up, and then you've done four hundred bucks of unpriced work and you're annoyed and the customer has no idea because you never said a word.

Rule of thumb. If it costs you real time or real material that your quote didn't cover, it's a change order. Write it.

Why you write it before you do the work, not after

This is the whole game. A change order before the work is a normal business conversation. A change order after the work is a bill for a surprise, and surprises are where customers dig in.

When you bring it up first, the customer is choosing to spend the money. They can say yes, say no, or pick a cheaper version. They feel in control, so they don't fight it. When you bring it up at the end, they feel cornered, like you snuck it on them, and even reasonable people get cheap when they feel cornered.

So the second the scope moves, you stop, you price it, you say it out loud. Even if you're standing right there with the tools in your hand.

How to say it without killing the vibe

You don't have to make it a big thing. Keep it light and matter of fact, like it's just how the job works, because it is.

In person it sounds like this. "Yeah I can add that. That's outside what I quoted so it'll be about [amount] extra. Want me to go ahead?" That's it. You said yes to the customer, you named the price, and you asked for the okay. Three seconds.

If you're not on site, a text does the same job. "Hey, happy to add the [thing] you asked about. It's not in the original quote so it'd be an extra [amount]. Want me to write it up and add it?" Now you've got it in writing and you've got their reply in writing, which is the part that saves you later.

The tone that works is not apologetic and not aggressive. You're not sorry for charging, and you're not daring them to argue. You're just a pro telling them what something costs. The calmer you are about the number, the less weird it feels to them.

What goes in the actual change order

Whether it's a text, an email, or a line on your invoice software, you want four things:

The date. What's being added, in one plain sentence. The price for that addition. And a line that says the original quote and timeline still stand otherwise.

That last line matters more than people think. "This adds [amount] and about a day to the schedule, everything else in the original quote stays the same." Now there's no argument later about whether the extra work pushed the whole price up or changed the deadline. You drew the box around exactly what changed.

Get a yes back in writing. "Sounds good" by text is enough for a small shop. You don't need a lawyer, you need a record.

When the change is bad news, like hidden damage

Sometimes the change order isn't the customer adding a want. It's you opening a wall and finding rot, or pulling up flooring and the subfloor is shot. This is the one that makes guys nervous because it's a price increase the customer didn't ask for.

Handle it the exact same way, just slower and with a photo. Stop, take a picture, show them. "So this is what was behind the wall, the framing's rotted here and here. I can't close it back up over that in good conscience. To fix it properly it's about [amount] and another half day. Here's what it looks like if we don't." Photos do the convincing for you. Almost nobody argues with a picture of rotted wood. What they argue with is a number on an invoice they never saw coming.

The contractors who get burned on hidden-damage changes are the ones who quietly fix it to be nice, eat the cost, and then resent the customer. Don't be that guy. Show the photo, name the price, let them decide.

The follow-up trap nobody warns you about

Here's where the money actually leaks. You send the change order text, the customer's busy and doesn't reply right away, and you've got a choice. Wait and hold up the job, or just do the work and sort the money out later. Most guys do the work. Then the change quietly never gets paid because there was never a clean yes, and bringing it up at the end feels awkward, so it dies.

That's the same hole that swallows unpaid quotes and forgotten invoices. Not the customer who refuses, the one who just went quiet on a number and never got a second nudge. You were on the next job, you forgot, and a few hundred bucks evaporated.

That's the gap I built QuoteChaser to close. It follows up on the quotes, change orders, and payments that go quiet, on a schedule, so the polite "hey, just need a thumbs up on that extra work before I do it" actually goes out on its own instead of living in your head until it's too late. You stay the easy-going one. The system does the chasing.

If you're tired of doing extra work for free because you never got the yes in writing, get on the waitlist here. It's built for one-to-ten-person trade shops, the guys with no office manager riding the paperwork.

Price the change before you swing the hammer, say the number like it's normal, and get the yes in writing. Do that and "while you're in there" stops being the phrase that costs you money and starts being the phrase that makes you more.
