Change order
What the job is worth now — not what you bid. Numbered, priced, approved, and counted.
The contract
Entered once. Every change order and the payment application read from it, so they cannot disagree about what the contract is worth.

No change orders on this contract.
Why this isn’t a template
Everything free in this space is a spreadsheet or a Word file you fill in and save as CO-3 final FINAL v2. A file can hold one change. It cannot hold the number that actually matters, which is what the contract is worth after all of them — original sum, plus every approved change, with the pending ones visible and deliberately not counted.
That figure is what you bill against. Get it wrong and you under-bill a job you already did the work on.
Pending is not approved
Pending change orders are tracked here and left out of the contract sum on purpose. Billing against work the owner hasn’t signed off is a common way to get an entire payment application held up rather than just the one line — so the tool keeps the two figures apart and shows both.
Say why, not just how much
Different reasons get challenged differently, so the reason is a field rather than an afterthought. An owner request is the easiest to defend if you name who asked and when. An unforeseen condition is the most disputed category of all, which is why the description needs to say what was found and why it wasn’t visible at bid. A change an inspector called for is rarely refused once it’s in writing with the item named.
Where it meets the other tools
The estimate is where the original contract sum came from. This is what happens to it. The payment application reads the same contract record, so the two can never disagree about what the job is worth — approve a change here and the billing updates itself.
For the work itself, the work order dispatches it and the work log proves it was done. On a smaller job where there’s no formal contract, an invoice with the extra itemised is often all this needs to be.
General information, not legal advice. A change order is a contract amendment — what it must contain and how it must be executed depends on your own agreement. Everything is built on your device and nothing is sent to our servers.
