Free change order generator for contractors

What to include in a construction change order

When a customer asks for different work after the estimate, write down what changes and what stays in the original scope. “Add electrical work” leaves too much open. “Add two kitchen outlets at the marked locations and remove the planned pendant light installation” gives both sides something specific to review.

Contractor and customer information

Include your business name and contact details, the customer’s name, and enough information to identify the job. If you’re working at more than one property for the same customer, include the work address in your notes.

Change order number and date

Give the document its own number and date. For example, CO-002 tells the customer which change you’re discussing when you send a revised copy or follow up on a question.

Reference to the original estimate or agreement

Identify the estimate number or agreement being changed. Add its date or the relevant scope description when that helps distinguish it from other versions. The estimate reference in the miniature and full editor is informational; it doesn’t connect the two records or update the original document.

Description of the requested change

State what the customer asked for, where it will happen, and how it differs from the original plan. For a renovation, describe the outlet locations and the fixture installation being removed, rather than relying on a conversation at the jobsite.

Added and removed work

List the new work separately from work that’s no longer being done. Specify whether the added price includes labor, materials, or both. If the homeowner will supply the fixtures, say so instead of including them in a material charge.

Price adjustments and credits

Show the quantity and price for each addition. Use a negative price for a credit, with a description such as “Credit: omit pendant light installation from estimate EST-1042.” Check that the credit reduces the net adjustment rather than adding another charge.

Revised totals

Keep the net change amount separate from the original project price. If you’re showing a revised project total, calculate it separately using the original amount and all agreed adjustments. The generator’s change order total represents this document’s adjustment; it doesn’t automatically recalculate the full contract value.

Notes and relevant terms

Record details that affect how you’ll do the changed work, such as customer-supplied materials or a scheduling change to discuss. Include the terms relevant to the change and make clear which details still need agreement. Creating or sending the document doesn’t itself obtain customer approval or modify an existing contract.

Example contractor change order

In this fictional renovation, homeowner Morgan Example asks Sample Electrical to add two kitchen outlets and omit a planned pendant light installation. The original estimate, EST-1042, covers $4,800 of work, including that installation. The homeowner now plans to keep the existing light.

Change order CO-002 · Date: October 11, 2026 · Reference: EST-1042

All quantities and prices below are illustrative, not recommended rates.

The change adds $520 of work and materials, less a $180 credit, for a $340 net increase. No tax or other adjustment is included in this example.

If this is the only agreed change, the revised project price would be $4,800 + $340 = $5,140. That calculation is shown here to explain the example. The generator doesn’t pull in the original project price or calculate that revised total for you.

A note could read: “Keep the existing pendant light. Add two kitchen outlets at the locations marked with the homeowner. Confirm the revised work and any scheduling change before starting.”

How to create and send a change order

1. Describe the changes in the free generator. Enter up to three changes in the miniature, with quantities and prices. Use a negative price for a credit on removed work. Add an estimate reference if you have one.
2. Continue to the full editor. Your entries carry over into an initially unsaved draft. Complete the document beyond the miniature’s fields.
3. Add the customer, references, and relevant details. Enter your company information, the change order number and date, and any notes or terms needed to explain the change. Review the original estimate reference.
4. Review the document and pricing. Check descriptions, quantities, additions, and credits. Confirm that the total is the change amount, rather than the price of the whole project.
5. Print or save as PDF. Review the document in the full editor, then choose a printer or Save as PDF through your browser.
6. Send it to the customer for review. Attach the PDF in your preferred email or messaging application. Ask the customer to check both the changed scope and the price adjustment.
7. Record any agreement separately. Use the approval process appropriate for your job and keep that record with the document. The free generator doesn’t collect electronic signatures, automate approvals, or track changes to an existing contract.

If you haven’t heard back, follow up with the change order number and another copy of the PDF. Clarify any open questions before starting the changed work. Saved documents remain in this browser on this device; keep an exported PDF with your job records as well.

Common change order mistakes

Describing additional work too vaguely

Replace “Extra electrical: $380” with the work and location. Name the two outlets being added and distinguish installation labor from materials so the customer can see what the added price covers.

Missing credits for removed items

Check the original estimate for work you’re no longer doing. List any agreed credit explicitly, with a negative price and a description tied to the removed item. Don’t leave the customer to guess whether the new price already includes it.

Leaving pricing unclear

Show quantities, unit prices, and the net adjustment. Check whether materials are included, supplied by the customer, or charged separately. Review each negative line to make sure it reduces the amount.

Failing to reference the original scope

Include the estimate number and describe the original item being changed. If there are several versions, add the date or other identifying details so everyone reviews the same starting point.

Starting changed work without documenting agreement

Send the description and pricing for review before you begin the extra work. Record what was agreed and keep it with the job information. A document you’ve created or sent isn’t a record of customer approval by itself.

Confusing the change amount with the project price

Label the change total as an adjustment. In the example above, $340 is the increase, not the price of the renovation. If you show the revised project total separately, check it against the original price and any other agreed changes.
