A change order template is a form. Every competitor site has one you can download. Fill in the blanks, get a signature, move on.
Except most of those templates leave out the field that actually protects your cash flow.
The revised payment schedule is the element most contractors leave out of change orders, and the one most likely to cause a payment dispute. You can document every added outlet, every linear foot of unexpected rock, every week of schedule extension. If the signed change order does not specify when and how the additional money gets paid, you have a scope agreement without a payment agreement. That gap is where disputes live.
This template includes all six enforceable fields, the revised payment schedule included. Download it, or read through each section below to understand why every field matters before you fill anything in.
What a change order template actually is
A change order construction form is a written amendment to the original construction contract. Either the contractor or the owner can request one. It updates the scope of work, the timeline, the price, or a combination of these.
The key word is "amendment." After both parties sign a change order, it should be attached and made part of the original agreement. Before that signature, it is a proposal. And proposals do not generate invoices.
That distinction drives the rest of this article. A change order template is not just a record of what changed on a job. It is the first document in a payment chain: signed change order, revised payment schedule, invoice. Skip a link and the chain breaks.
The 6 fields every change order template must include
Most downloadable forms cover three or four of these. Six elements make a change order enforceable and billable:
1. A clear description of changes
Not "misc. extra work." A detailed description of what is changing, with those changes tied to the scope of the original contract. Vague language invites disputes at invoice time.
2. The parties involved
Owner, contractor, and any relevant subcontractors. Change orders are not valid until signed by all parties involved.
3. Updated total contract price
Include the dollar amount by which the price is being raised or lowered and the updated total. The cost breakdown must itemize labor, material, equipment, and any other categories, clearly showing quantities and unit rates.
4. Markup disclosure
A clear breakdown of overhead, profit, tax, insurance, and bonding applicable to the project. Burying markup in inflated line items erodes trust. Disclosing it as a separate line builds it.
5. Revised completion date
If the change adds work, it probably adds time. Document the new date.
6. Revised payment schedule
If the payment schedule from the original contract will be impacted, a new payment schedule needs to be detailed in the change order. This is the field most templates omit, and it is covered in depth below.
What triggers a change order
Five categories of change cover nearly every situation a contractor will encounter:
| Category | Example |
|---|---|
| Scope | Client adds a bathroom to the second floor |
| Schedule | Weather delays push the timeline by three weeks |
| Materials | Specified lumber is unavailable; substitute required |
| Site conditions | You open a wall and find asbestos, or dig a foundation and hit rock |
| Regulations or codes | A mid-project code update requires additional fire stopping |
Each of these affects cost, timeline, or both. The change order documents the corrective action and makes it billable.
COR vs. change order: two documents, one process
Contractors sometimes confuse these, or treat them as interchangeable. They are not.
A Change Order Request (COR) is what the contractor submits. It outlines the change in scope of work, cost, and schedule impact. Whether the change was requested by the client, caused by unforeseen conditions, or triggered by something else, the contractor is responsible for clearly outlining the change and presenting the costs in the COR.
Once approved, the customer issues a change order that formally updates the contract value.
On smaller residential jobs, the COR and the change order are often the same document. On larger projects, a COR sent by a general contractor to the owner is typically a package bundling multiple subcontractor CORs together. If you are a sub, your COR feeds into the GC's package. If you are the GC, you are assembling CORs from your subs into a single change order for the customer.
How to fill out the template: 5 steps
The process from identification to signature follows five steps:
Step 1: Identify the need. Something changed. Document what happened and why the original contract no longer covers it.
Step 2: Write the proposal. The proposal includes estimated costs for the requested changes and outlines any resulting changes to the completion date and payment schedule.
Step 3: Negotiate. The owner reviews the proposal. Numbers get adjusted. Scope gets refined. Clear itemization pays off here, because vague line items invite negotiation on everything.
Step 4: Prepare the formal change order. Once the details are agreed upon, complete the document with all six elements listed above.
Step 5: Get the signature. Each party acknowledges the document with their signature. Until this step happens, the change order is not legally valid.
The field most contractors skip
The revised payment schedule deserves its own section because skipping it is where the money problems start.
Consider the payment chain. The signed change order authorizes the revised scope. The revised scope generates a revised payment schedule. The revised payment schedule produces the invoice. Skip or delay the change order, and every step downstream stalls with it.
Now consider what happens when the change order is signed but the payment schedule is not updated. You have authorization to do the work. You do the work. You send an invoice for the additional amount. The client looks at the invoice and sees a number that does not match any agreed-upon milestone or draw schedule. That is a dispute.
The numbers back this up. 56% of U.S. small businesses are currently owed money from unpaid invoices, with the average outstanding balance sitting at $17,500. Nearly half (47%) report at least some invoices are overdue by more than 30 days. Change orders without revised payment schedules feed directly into these statistics, because submitting an invoice with unapproved changes damages the relationship and makes payment less likely.
The fix is straightforward. When you fill out the change order template, fill out the payment schedule section. Specify when the additional amount is due, whether it attaches to an existing draw or creates a new milestone, and what the updated total contract value is at each payment point.
When to use AIA Form G701 instead
This template works for residential and light commercial projects where the contractor and customer sign directly. For projects requiring an architect's signature, the standard form is AIA Form G701 from the American Institute of Architects.
If your project has an architect of record, use G701. If it does not, this template covers what you need.
After the signature: turning a change order into an invoice
The signed change order is not the finish line. It is the starting point for getting paid.
Once signed, the change order feeds into your construction invoice. The line items on that invoice should trace directly back to the itemized cost breakdown in the change order. If the change order specifies $2,400 in additional electrical labor and $800 in materials, the invoice should show those same figures, not a lump sum of $3,200 with no breakdown.
The revised payment schedule you documented in the change order tells you when to send that invoice. If you tied the additional work to an existing draw, invoice it with that draw. If you created a new milestone, invoice when the milestone is met.
This is the full chain: change order, revised payment schedule, invoice. Each document references the one before it. The contractor estimate set the original expectations. The change order updated them. The invoice collects on them.
Getting the change order signed is step one. Getting paid is the part that matters.
