This is an example. For Sven, the quote now goes to the customer as a link, who approves it with one tap.

The painting was never the problem. The evenings were.

Measure up, calculate at home, put it in Word, email it. And then hope the customer hadn't already picked someone else.

BeforeForty-five minutes per quote, in the evening at the kitchen table. The customer heard back after a few days.

NowTwo minutes, on the customer's doorstep. The quote arrives before the coffee is finished.

Built with one request to Claude

Sven can't code. He told Claude how he builds up a price, and got a tool that works exactly the way he calculates.

I'm a house painter. Make a calculator for my phone that lets me create a quote at the customer's. I charge € 230 per exterior window frame, € 145 per interior door, € 14 per m² of wall and € 16 per m² of ceiling. Front door € 340, wood rot € 165 per spot, scaffolding € 290. If the old paintwork is fair or poor, add 10 or 25 percent.

Claude builds it. Waterbloom makes sure it lives at its own address, so it works on any phone and Claude can adjust it later when a price changes.
