Found extra work? Photo, voice note, thirty seconds. It comes back written up and priced, your customer taps once to approve, and it's on the final invoice with their name against it.
Most trades assume unbilled extras come from customers refusing to pay. They rarely do. It goes four other ways — and only one of them involves a row.
Found on a Tuesday, invoiced six weeks later, reconstructed from memory. Nobody argues because nobody remembers.
The quote said £8,450 and the invoice says £11,200. You take £600 off rather than have the conversation.
"I told him on site" against "he never mentioned it". Without evidence you lose that one every time.
A disputed £400 extra sits on top of nine grand for six weeks. That's cashflow, not just margin.
No forms. No job set up first. You can do it standing in a trench with dirty hands and one bar of signal.
"Customer wants the old fence posts out as well. Two of us, half a day, plus disposal." Talk like you'd talk to your mate.
Comes back as a properly worded variation with labour, materials, plant and disposal split out. Change any figure you don't like.
A link by email or text. No app, no login, one button. Their name and the time are recorded against the photo and the price.
Each extra sits as its own line with the date they agreed it. No lump sum at the end, no conversation you've been dreading.
Big targets, high contrast, readable in daylight. Designed for gloves and a cracked screen.
Photos hashed and timestamped on capture. Approvals recorded with name, time and device. Prices locked once agreed.
Cost rates sit behind your charge rates and are never sent to the customer. Not hidden in a page they could inspect — never sent at all.
Your lads raise extras from their own phones. You see who's finding money and who's giving it away.
Approved extras become their own lines on the final account, each carrying the date and name of whoever agreed it.
It does variations. It won't try to become your CRM, your scheduler or your accounts package.
