The GC said "just do it"? Get it in writing: labor, materials and equipment priced, signed on your phone, sent as a T&M tag PDF before you leave the job.
Get paid for the work nobody wrote down.
Extra work starts with someone on site saying "just do it, we'll sort the paperwork later". Months later the paperwork is the argument. ChangeProof turns that moment into a priced, signed PDF before you leave the job.
SIXTY SECONDS, ON SITE
• Describe the extra work and why it sits outside the contract
• Name the person who authorized it — the field that decides who pays
• Add labor: who, what trade, hours, rate, overtime as its own line
• Add materials and equipment, with markup if your contract allows it
• Attach photos of what you actually did
• Get the client or superintendent to sign on the screen
• Export one PDF and send it
THE TOTAL IS THE POINT
Every line adds up as you type it, so the amount is on screen while the person who approved the work is still standing next to you. No spreadsheet afterwards, no rebuilding it from memory on Sunday night.
BUILT FOR THE FIELD
• Works fully offline — no signal needed
• No account, no login
• Your first tag is free
• Tags stay on your iPhone
• Sequential tag numbers, so you can point to T-014 and everyone knows which one
WHY THIS DOCUMENT MATTERS
Two thirds of specialty contractors still write time and materials on paper tags. Those tags get lost, and the work gets written off. A tag with the labor priced, the photos attached and both signatures on it is a different conversation with the general contractor — one you can send the same day.
