Free Change Order Template for Contractors

A change order is the most important document most contractors never use. Until it costs them thousands of dollars.

Here is a scenario every contractor has lived through: you are midway through a bathroom remodel. The homeowner walks in, points at the wall, and says, "Can we move that outlet over there? And actually, let's add a heated towel rack." You say sure. You do the work. Then the final invoice comes, and the client says, "I never agreed to pay extra for that."

A change order prevents this. Every single time.

What Is a Change Order?

A change order is a written document that records any change to the original scope of work, schedule, or contract price. It describes what is changing, why, how much it costs, and how it affects the timeline. Both the contractor and the client sign it before the additional work begins.

Think of it as an amendment to your original contract. The original agreement says "install 10 recessed lights." The client wants 12 instead. A change order documents the addition of 2 lights, the cost, and both parties' agreement.

Why Change Orders Matter

They Protect Your Revenue

Without a change order, you have no documentation that the client agreed to pay for additional work. In a dispute, it is your word against theirs. Judges and arbitrators do not rule in your favor based on "they told me to do it."

They Prevent Scope Creep

Small changes add up fast. "Can you just..." is the most expensive phrase in construction. A change order forces everyone to acknowledge that a change has a cost. When the client has to sign off on an extra $350 for that outlet relocation, they think twice about whether they really want it.

They Keep the Project on Track

Changes affect timelines. Adding a heated towel rack means ordering the unit, running a dedicated circuit, and potentially waiting for an inspection. A change order documents the schedule impact so the client cannot complain that the project is running behind.

They Build Trust

Clients respect contractors who are organized and transparent. A change order shows that you take the project seriously, that you are not padding invoices after the fact, and that every dollar is accounted for.

What to Include in a Change Order

Every change order should include these elements:

Header Information

• Change order number (sequential: CO-001, CO-002, etc.)
• Date
• Project name and address
• Original contract number or reference
• Contractor name and business info
• Client name

Description of Change

This is the most important section. Be specific about:

• What is changing (add, remove, or modify)
• Why the change is being made (client request, unforeseen condition, code requirement)
• Where on the project the change applies

Bad example: "Additional electrical work"

Good example: "Add (2) 20A dedicated circuits for heated towel rack in master bath. Includes running 12/2 Romex from Panel B in basement, installing (1) single-pole 20A breaker, and (1) GFCI outlet behind towel rack unit. Required per client request during walkthrough on March 8."

Cost Breakdown

Show the client exactly what the change costs:

Schedule Impact

State clearly how the change affects the timeline:

• "This change adds 1 day to the project schedule."
• "No schedule impact. Work will be completed during the electrical rough-in phase."
• "This change requires an additional inspection, which may add 2-3 business days."

Revised Contract Total

Show the running total:

Signatures

Both parties must sign and date:

• Contractor signature and date
• Client signature and date

No signature, no work. This is non-negotiable.

How to Use Change Orders Effectively

Create Them in Real Time

Do not wait until the end of the day or the end of the week to write up a change order. When the client asks for a change, write it up right then. The longer you wait, the more likely you are to forget details or the client is to forget they asked for it.

Mobile-friendly tools make this easy. With Linkster, you can create a change order from your phone on the job site, add line items, and send it to the client for digital approval in minutes.

Number Them Sequentially

Use a consistent numbering system: CO-001, CO-002, CO-003. This makes it easy to reference specific changes on your final invoice and keeps everything organized if there is ever a dispute.

Reference Them on Your Invoice

When you send the final invoice, list each change order by number with its amount. The client should be able to trace every dollar on the invoice back to either the original contract or a signed change order.

Keep Copies

Store every signed change order with the project file. Digital is best because paper gets lost, damaged, or left in your truck. A good project management system keeps all change orders attached to the job automatically.

Common Change Order Mistakes

Doing the Work Before Getting Approval

This is the most common and most costly mistake. You do the extra work, then write up the change order after the fact. The client says they never agreed to it. Now you are stuck.

Always get the signature before you start the additional work. No exceptions.

Being Too Vague

"Extra work per client request -- $500" is not a change order. It is an invitation to a dispute. Be specific about what was done, what materials were used, and how labor was calculated.

Not Including Schedule Impact

If a change adds time to the project and you do not document it, the client will blame you for running behind. Document the schedule impact on every change order, even if it is "no impact."

Skipping Small Changes

"It is only $150, not worth the paperwork." Those $150 changes add up. Five undocumented small changes is $750 you might never collect. Document everything.

Moving Beyond Paper Change Orders

Paper change orders work, but they are slow and easy to lose. Digital change order management solves the biggest pain points:

• Instant delivery -- send it to the client's phone immediately
• Digital signatures -- approval in seconds, not days
• Automatic invoice updates -- approved changes flow directly to the invoice total
• Organized records -- every change order is stored with the job, searchable and accessible
• Audit trail -- timestamped approvals that hold up in disputes

Linkster includes built-in change order management on all paid plans. You create the change order, the client reviews and approves it in their portal, and the approved amount automatically updates the job total. When you are ready to invoice, every change order is already accounted for.

The Bottom Line

Change orders are not bureaucracy. They are insurance. They protect your revenue, prevent scope creep, and keep projects on track.

Start using them on every project, for every change, no matter how small. Your future self -- the one not arguing with a client about an extra $500 -- will thank you.
