Change order slip
Have the customer sign a change on your phone before the extra work starts: what it adds, the new price and the days, against the estimate and its 10% line.

How it works
- 1 Pick the job. Its estimate is the price every change is measured from, with its 10% line.
- 2 Write what changes and why, and price it in lines the way the estimate does: labour, materials, a service. A change can take work out too.
- 3 Hand them the phone to sign with a finger, or mark it signed on paper. Once signed it's locked, exactly as they agreed to it.
- 4 The panel keeps the running price: the estimate, what's signed, and what's still waiting on a signature, against the line. Bill the job and the signed changes go on the invoice.
Signed in, each change is kept on its job in your account, for you only: never in a link, a log or an AI prompt, and it's in your export. The customer's name on a printed slip is read from your customers when you print it, and isn't kept on the change. Signed out, the page shows a made-up job that's never kept.
Good to know
- Why get a change signed before the work?
- Because "you said it'd be $6,400" is the argument at the end of most jobs that grew. In Ontario, when a consumer contract includes an estimate, the Consumer Protection Act says you can't charge more than 10% above it unless the customer agrees to the extra or different work. A signed slip is that agreement, with the price on it. The check is on the price before tax. Protecting consumer rights and safety
- What should a change say?
- What's added or taken out, why, what it costs, and whether it moves the finish date, signed and dated by the customer. Ontario's guide for home renovation and roofing businesses asks for changes to the contract to be in writing. Everything else in the estimate stays as it was, and the slip says so.
- Does a finger signature on a phone count?
- Electronic signatures are generally accepted for agreements like this one (verify for your province and your contract). It's kept with the name, the date and how it was signed, and printed on the slip. If you'd rather have ink, print the slip, have them sign it, and mark it signed on paper.
- Something went wrong in a signed change?
- Write another change that puts it right. A signed change can't be edited, so what the customer agreed to is always what's on file.
- Is this legal advice?
- Guidance, not legal advice. It's based on Ontario's consumer rules as checked in October 2026. Other provinces have their own consumer laws, and work for a business is different again. Check anything you're unsure of with a lawyer or your province.
