You know the story too well.
You did the job, the extra shifts, the urgent variation, the verbal instruction that “should be fine.”
Then suddenly…
“That’s not what we agreed.”
“We never asked for that.”
“Can you send over the paperwork?”
And just like that, the money starts slipping.
- The client forgets the change of scope.
- The supplier insists they delivered everything.
- The variation you discussed on site? Vanished.
If there’s no proof, it didn’t happen.
And if it didn’t happen, you don’t get paid.
That’s not just frustrating, it’s dangerous.
For your margins. For your business. For your team.
What Happens When You Don’t Use ProntoCalc?
- You lose track of verbal instructions.
- You miss key site photos that prove what happened.
- You waste time pulling together evidence after the fact, when the damage is already done.
And worst of all?
You keep doing the work, without getting paid for it.
ProntoCalc isn’t more admin. It’s more protection.
In just minutes a day, you can:
✅ Log variations
📸 Snap site photos with context
📝 Record instructions, changes, and delays, on the spot
That’s your paper trail.
That’s your proof.
That’s your pay, protected.
You’d never leave your van unlocked overnight.
Don’t leave your work unprotected either.
