BauhelferSay it in your language. Your customer gets it in German.
Bauhelfer.app is your office in your pocket: you speak into your phone — in Russian, Ukrainian, Polish, Croatian or English — and get a clean German quote or invoice. No typing.
Try it for freeHow it works
Speak
Hold the microphone button and say what it's about — in your language, German trade terms are fine.
Check
The app shows you in your language what it understood. If something is missing, it asks — it never guesses.
Send
A finished PDF in German with all mandatory details — straight to your customer.
Example with made-up data — this is what the app looks like.
What the app does
Quotes & invoices
Quotes with versions, invoice only after acceptance. Issued invoices are frozen — corrections by cancellation, as the German tax office requires.
Receipts by photo
Snap a receipt — it's assigned to the right job as material or subcontractor cost.
Working hours by voice
“Today 6 hours at Müller's, Vova 4 hours” — done, for you and your helpers.
What's left for you?
Revenue minus material and subcontractors: see at once what a job really earns.
Works offline
Basement, building site, no signal? Recordings stay on the phone and upload once you're back online.
Your language
Русский, Українська, Polski, Hrvatski, Deutsch, English — the app talks to you in your language.
