Pilot with a shell-construction firm — Berlin

AI Invoice Agent — from the crew's day to the invoice, the same evening

A small operations suite for trades businesses: the foreman reports the day by voice in his own language, the AI turns it into a German report with priced positions, and the owner sends the invoice with one click.

AI Invoice Agent — from the crew's day to the invoice, the same evening
1

The problem

On a building site the crew changes daily and half of it does not write German. Hours get noted on paper, hidden work is covered before anyone photographs it, and the invoice is written weeks later from memory — which is where the money goes missing.

2

What we built

The worker opens the app on his phone, clocks in on his site, speaks his report in Bosnian, Croatian or English, and photographs hidden work before it is closed. The office gets a German daily site report with team hours, material and photos, ready as a PDF for the client. Positions are priced from the company's own price list. The owner reviews, adjusts and sends the invoice by email — and sees at any time who is where, who is on leave, which requests await approval and how many hours are still unbilled per site.

Our contribution

Built end to end — the report-to-invoice flow, the time clock and leave handling, photo documentation, the daily report PDF, the trade-specific vocabulary for five industries, and the sales package for the pilot.

The result

  • Invoice per § 14 UStG the same evening, sent with one click
  • Hidden work documented with photos before it is covered
  • Unbilled hours visible per site — lost money made visible
  • Time clock, leave requests and approvals for the whole crew, on a phone
