The job finished on time. On budget. No complaints.
The client never came back.
Why? Because throughout the whole job they had no idea what was happening. No updates. No visibility. No confidence that things were under control, even when they were.
The work was good. The communication wasn't.
And for most clients, that's the thing they remember.
Transparency isn't a nice-to-have. It's part of the product. Clients who feel informed trust the builder. Clients who trust the builder come back. Clients who come back don't need to be won.
ProntoCalc gives builders the data to keep clients in the loop at every stage, so the relationship doesn't end at handover.

"I'll sort the invoice when I'm back in the office."
That sentence has cost builders thousands.
Every hour between finishing a job and raising the invoice is an hour where:
— Extras get forgotten
— Details blur
— The final bill shrinks
The job was right. The work was done. But the invoice didn't reflect it.
ProntoCalc Ltd means the invoice is ready before you've left the site.
While the job is fresh. While you remember the extras. While the number is right.
We’ve all been there.
“Could you just have a look at...”
And before you know it you’re three days in, at mate’s rates, with materials that have already wiped the margin.
Working for family and friends is part of the trade. But doing it for less than it costs you isn’t generosity, it’s a subsidy straight out of your business.
Knowing your real numbers makes these conversations easier. When you know what a job actually costs, you can decide what to charge, rather than just saying yes and hoping for the best.
ProntoCalc helps you know the number before the conversation, not after the job is done.
