Found water damage under the sink. Replace 8ft section + sister joist.
Built for remodelers, GCs, electricians, plumbers, roofers, painters, landscapers, and every trade that's done free extras.
The client said yes on the phone. No text, no email, no record. When the invoice hits, suddenly they don't remember agreeing to it.
You did the extra work in good faith. Now they're disputing the final bill and you have nothing in writing to back it up.
The average disputed extra is $300–$800. Multiply that across a few jobs a year and you're leaving thousands on the table.

Open ScopeProof on your phone and photograph the extra — the rotten joist, the surprise wiring, the additional demo.

"I used to text clients 'is that extra OK?' and call it approved. Lost $1,200 on a bathroom remodel because of it. Now every extra has a signed approval before I touch it."

"My GC tried to say I never got approval for the panel upgrade. I pulled up the proof packet with the photo, price, and his client's signature. Conversation over."

"Setup took five minutes. Sent my first approval link on a real job the same day. Client approved it from her phone while I was still on site."

"Collected $3,400 in extras on a kitchen reno I would have eaten before. The signed PDF made the final invoice a non-conversation."

"Homeowners actually respect the process now. They see the photo and price up front, tap approve, and we keep moving. No more 'I didn't agree to that.'"

"I run three crews. Before ScopeProof, every Friday was a fight over what got added. Now I just open the dashboard and see every approved dollar in one place."

"First week I used it I caught $880 of work I would have done for free. The link is so simple the client signed from his truck."

"I'm a one-woman shop. This replaced a messy folder of texts and screenshots. Every job now closes with a clean proof packet."
