Handling Change Orders Without Losing the Client

By Nicholas Dunn · September 5, 2026 · 5 min read

TL;DR

A change order is any time the work shifts from what you bid — scope addition, material switch, design pivot, or a hidden condition you uncover after demo. Put it in writing, get it signed before you proceed, and frame it as a heads-up rather than a price hike. Bid the real cost every time; lowballing to be nice trains clients to expect free changes.

Change orders are not the problem. Handling them badly is. Done right, a change order protects the relationship and your margin at the same time. Done wrong — verbal, vague, or apologetic — and you end up either eating cost or fighting with a client you used to like.

I've been on both sides of this. As a finish carpenter running jobs, and now coaching trim-company owners through the business side. The owners who struggle with change orders almost always have the same two problems: their process is informal, and their framing is adversarial. Both are fixable.

What actually triggers a change order?

Four things, basically:

  • Scope addition. "While you're here, can you also do the mudroom?"
  • Material switch. They picked a different profile, or want stain-grade instead of paint-grade.
  • Design pivot. The built-in was going to be open shelves; now they want doors.
  • Hidden condition. You pull baseboard and find rotted subfloor. Old houses are full of these.

If any of those move the labor, the materials, or the timeline you bid, it's a change order. The trap most owners fall into is treating the first three as "real" change orders and the fourth as something they have to absorb. You don't. Hidden conditions are exactly what change orders exist for.

What's the right change order process?

Three rules. Written. Signed. Before work proceeds.

  1. Written. A short description of what changed, the additional cost, and the time impact. That's it.
  2. Signed. Physical signature, e-sign, or at minimum a clear "yes, proceed" reply in writing.
  3. Before work proceeds. The moment you start the extra work without sign-off, you've lost your leverage and your protection.

You don't need fancy software. A simple Google Doc template works fine — job name, original scope reference, description of change, cost, time impact, signature lines. Save it, duplicate it for each one, send it as a PDF. The format matters less than the discipline of using it every single time.

How do I present a change order without making it adversarial?

This is where most owners blow it. The framing they use is "this is going to cost you more" — which immediately puts the client on the defensive. The framing that works is "I want to make sure you know what's happening so there are no surprises."

You're not asking for permission to charge them. You're informing them of a decision point. The cost is just part of the information. Walk them through it like a partner, not a salesman:

  • Here's what we found, or here's what's changed.
  • Here are the options.
  • Here's what each option costs and how it affects the schedule.
  • Which way do you want to go?

Most clients respect this. The ones who don't are usually the same ones who would have been a problem anyway. Same dynamic applies on the other side of the table — see when your contractor pushes back on trim for the GC version of the same conversation.

Should I always charge for changes?

Almost always. There's a narrow exception for small relationship-investment items — an extra hour of caulking, a piece of shoe mold in a doorway nobody bid. Eating those occasionally is fine and builds goodwill.

But here's the rule that matters: bid the real cost every time you do charge. Do not lowball change orders to "keep the client happy." That's the single biggest mistake I see. When you discount the change, you're teaching the client that your numbers are soft, your changes are cheap, and they can keep asking for more. You're also losing money on every one.

If you're undercharging on changes because you're afraid of the conversation, you've got a pricing-confidence problem, not a client problem. That's the same underlying issue I wrote about in why trim companies underprice their work.

The verbal-agreement trap

"Yeah, just add it." Famous last words. Verbal yeses on the jobsite become "I never agreed to that price" when the final invoice lands. I've watched owners lose four-figure change orders this way because they trusted a thumbs-up from the homeowner and didn't paper it.

Two minutes. That's all it takes to send a text or email with the change, the cost, and "reply yes to proceed." Anything bigger, use the signed template. Your future self will thank you.

How do I cut change orders down in the first place?

Tighter specs upstream. The majority of change orders I see came from a bid that was vague to begin with — profile not nailed down, who supplies material not specified, what "complete" looks like never defined. If your bid doesn't say it, the client will assume the more expensive interpretation and you'll eat the difference.

I broke down exactly what belongs in a tight spec in how to write a trim specification, and the bid-reading side of it in how to read a trim carpenter bid. Read both. The hour you spend tightening your spec template will save you ten hours of change-order conversations across the year.

Job costing matters here too — without it, you won't even know which jobs are bleeding from uncompensated changes. Job costing for trim companies covers the basics.

Bottom line

Change orders aren't a sign the relationship is failing. They're a sign the job is changing — which happens on almost every project. The owners who handle them well share three habits: they write everything down, they frame the conversation as information rather than confrontation, and they charge the real cost every time. The owners who struggle do the opposite on all three.

If you're tired of eating changes you should have charged for, or losing clients over conversations that should have been routine, that's exactly the kind of operational fix I help trim-company owners work through.

Questions

Frequently asked

Anything that moves the job off the bid. A scope addition (add a closet build-out), a material switch (paint-grade to stain-grade), a design pivot (different profile, different layout), or a condition you discover after work starts (rotted subfloor, out-of-plumb walls in an old house). If it changes the labor, materials, or timeline you priced, it's a change order.
