Insights · BuildersHow do custom home builders stop losing money on change orders?

Most builders don't lose money on change orders because they price them badly. They lose it because some changes are never priced at all. A client asks for a wider window on a site walk, the framer says "no problem," and three weeks later nobody remembers who agreed to what. The work got done. The invoice never did.

Where the money actually goes

The loss sits in one gap: between "the client asked" and "the client signed." Everything that happens in that gap is at risk.

• Changes agreed on site. A client talks to a foreman or a sub, not to you. The change gets built, but it never reaches the office.
• Work that starts before a signature. Even when a change is written up, the crew often starts before the client approves the price.
• The ripple nobody priced. A change costs more than its materials and labor. It can push the next trade back, add a week of supervision and rentals, and move money out of your account before the next draw comes in.
• Changes that never become a bill. An approved change sits in an email or a text thread and never makes it onto the next draw or invoice.

None of these is a pricing problem. Each is a handoff problem: information that exists in someone's head or phone and never reaches the place where it turns into money.

A change-order process that fits on one page

You don't need another software subscription to close this gap. You need four rules your whole team knows, and one log everyone writes to.

1. Every change gets a line in the log the day it is asked for. What changed, which trade it touches, who asked and the date. Price can come later. The line can't.
2. No work before a signature. The client approves the price in writing, by text or email, before anyone picks up a tool. If a change truly can't wait, the owner decides, and the log shows it.
3. Every change is priced the same way. Pick one method and stick to it: cost plus your contract markup, cost plus a flat fee, or a fixed price per change. Add a line for schedule time when a change adds days.
4. Approved changes go on the next bill automatically. Decide up front whether clients pay in full before work starts, half before and half after, or with the next draw, and put that in the contract.

Make it easy for the field

A process only works if the people on site use it. Most foremen and subs will not open an app at the end of a long day. They will send a text.

So let them keep texting. A short message such as "client wants the island moved 2 feet, plumber needs to reroute" can become a log entry: the change, the trade and the date, with the original words kept next to it. If the foreman writes in Spanish, keep the Spanish and add the English. Nobody on the crew has to change how they work. The office, or an AI assistant set up for this one job, does the data entry.

Two rules keep that trustworthy. The assistant never fills in a cost or a date it wasn't given; it leaves the cell blank for a person to complete. And nothing goes to a client until a person has read it.

See the ripple before you say yes

A good change-order log answers three questions for every change, not just one:

• Budget: what does it add to that trade's budget and to the contract price?
• Schedule: does it push the trades that come after it, and by how many days?
• Cash: how much money goes out before the client's payment or the next draw comes in?

If the change adds living space, check it against what the permit allows before you agree to it. Finding that out after framing is expensive.

You can try this on sample numbers in the free Builder Kit. Its change-order tab prices each change, checks it against the permitted square footage, and shows what approved changes do to the schedule and to the money going out each month.

The Monday review

Once a week, before the site meetings start, look at one short list: every change that is not yet signed, with any work already started on it at the top. That list is where the money leaks. Ten minutes on it every Monday will catch more than a month of cleanup at the end of the job.

Then check that every change approved last week is on the next draw or invoice. If it isn't, add it before you forget why it mattered.

Common questions

What is a change order in construction?

A change order is a written agreement to change the work in a construction contract, with the new price and any added time. It protects both the builder and the client by recording what was asked for and what it costs.

Should work start before a change order is signed?

As a rule, no. Once the work is built, it is harder to agree on a price. If a change truly can't wait, the owner should make that call deliberately and record it in the log.

How should builders price change orders?

Use one consistent method, such as cost plus your contract markup, cost plus a flat fee, or a fixed price per change. Add a charge for schedule time when a change adds days to the job, since supervision, rentals, insurance and loan interest keep running.

Do I need construction software to track change orders?

Not to start. A well-designed spreadsheet or QuickBooks, a simple log and four clear rules are enough for most small builders. Software makes more sense once the habit is in place and the volume justifies it.

Can AI help with change orders?

Yes, with limits. AI can turn a foreman's text into a log entry, draft the approval message for the client and flag unsigned work. A person should still set the price and approve anything that goes to a client.
