Change Orders: How to Document Them (Before They Become Disputes)

You're halfway through a bathroom remodel. The homeowner walks in and says:

"Hey, while you're at it, can you add a few more outlets? And maybe move the vanity to the other wall?"

You say sure, figure it's a couple hundred bucks, and keep working.

Three weeks later, the invoice goes out. And then comes the call:

"Why is this $3,000 more than we agreed? You said you'd throw those outlets in."

Now you're in a he-said-she-said dispute over something that should have been documented.

Verbal change orders are the #1 cause of payment disputes in construction.

What Is a Change Order?

A change order is a written document that modifies the original contract. It captures:

• What changed. New work, deleted work, modified work.
• The cost. How much extra (or less) it will be.
• The timeline. How much extra time (if any) it will take.
• Signatures. Agreement from both parties.

Without a change order, you have:

• Your memory of what was said
• Their memory of what was said
• No written record
• A dispute waiting to happen

Why Change Orders Go Wrong

1. Verbal Agreements

"Sure, I can add that." "No problem, we'll figure it out."

These seem reasonable in the moment. But memory is unreliable, and clients tend to remember lower numbers than you remember quoting.

2. "Throwing It In"

Clients often assume small changes are included in the original price. "You're already here, can you just...?"

Without documentation, they'll argue it should have been free.

3. Scope Creep

One small change leads to another. Each change seems minor, but combined they add up to thousands in extra work — none of which was documented.

4. No Price Discussion

The change is discussed, but not the cost. Client assumes it's minimal. You assume they understand it's extra.

5. Email Chains

Even if you discuss via email, if you don't have a clear "yes, I agree to this amount," you're still in dispute territory.

How to Document a Change Order

Every change order should include:

The Change Order Process

1. Client requests a change. Verbally, by email, or in person.
2. You stop and document. Don't just say "sure" and keep working.
3. You estimate the cost. Labor, materials, any other costs.
4. You present the change order. In writing, before the work begins.
5. Client signs or declines. No work until you have a signature.
6. Work proceeds. After you have written approval.

What If the Client Won't Sign?

Sometimes clients say:

• "Can't we just figure it out at the end?"
• "I trust you, just do it."
• "This is slowing things down."

Your response:

"I want to make sure we're on the same page about cost. I've had situations where clients were surprised by the final invoice, and I don't want that to happen here. A quick signature now saves us both a lot of hassle later."

If they still refuse to sign, don't do the extra work.

It's better to pause and explain the process than to do work you won't get paid for.

Change Orders by Communication Method

In Person

Client says: "Can you add outlets in the bedroom?"

You say: "Absolutely. Let me write this up and get you a price before we start."

Then: Write it up. Get a signature. Then do the work.

By Phone

Client calls: "Hey, I want to change the tile in the bathroom."

You say: "Got it. I'll text you a change order with the updated price. Once you confirm, we can proceed."

Then: Send a text or email with the details. Get written confirmation.

By Email or Text

Client texts: "Can we add can lights in the kitchen?"

You reply: "Sure! That would be $450 for 6 can lights installed. Here's what's included: [details]. Please confirm and I'll add it to the invoice."

Then: Wait for their written "yes" before proceeding.

When to Use Change Orders vs. When to Adjust the Final Invoice

Always Use Change Orders For:

• Any work outside the original scope
• Additions the client requests
• Material substitutions
• Design changes
• Unforeseen conditions (plumbing inside walls, rot under flooring)
• Timeline extensions
• Anything that affects the price

You Can Adjust Without Change Orders For:

• Minor adjustments within the same trade (moving an outlet 6 inches)
• Work explicitly included in the original contract
• Credits for client-supplied materials (document these too)

How Many Change Orders Is Too Many?

It depends on the project size, but if you're doing more than 5-10% of the original contract value in change orders, something is wrong.

Possible causes:

• The original scope wasn't defined clearly enough
• The client keeps changing their mind
• You're underpricing the original contract and making it up in change orders

The fix: Better upfront scoping, detailed contracts, and clear communication about what is and isn't included.

Change Order Template (Quick Version)

For smaller changes, a simplified version:

What If You Already Did the Work Without a Change Order?

Sometimes you just... did the work. No change order. Now what?

Immediately:

1. Document what was discussed (write down the conversation while it's fresh)
2. Document what was done (photos, receipts, hours)
3. Send an email summarizing: "Per our conversation on [date], we added [work]. The cost for this was $[amount]. Please confirm."
4. Follow up until you have written acknowledgment

If they dispute:

• You have your documentation
• You have photos of the work done
• You have receipts for materials
• It's better than nothing — but nowhere near as good as a signature

Key Takeaways

• Verbal change orders = payment disputes. If it's not written, it didn't happen.
• Stop work until you have approval. "Sure, let me get you a price" is the right response, not "no problem."
• Document every change. What changed, why, how much, and signatures.
• Email/text counts. But formal change orders are better.
• Scope changes add up. Track change order totals against original contract.

The change order process feels like it slows things down. But it's faster than arguing about money after the work is done.

"Let me write that up" takes 5 minutes. Arguing about it takes months.
