I built a voice-to-invoice bot for German construction companies
No App, No typing, No training needed... Just speak --> get a professional PDF Invoice in second.
Here the workflow :
- Contractor sends a voice message on Telegram
- Whisper AI transcribes it
- GPT-4 extracts items, quantities, prices
- A professional PDF invoice or Angebot is generated automatically
- Bot sends the PDF back instantly on Telegram
Full stack running in production: → n8n on Hetzner VPS 🇩🇪 → HTTPS via domain kinvoice → Telegram Bot as the UI → html2pdf for document generation → Multi-document support (Rechnung + Angebot)
The contractor doesn't need to learn any software. They just talk. The bot does the rest.
This is what I'm building for German SMEs — simple AI automation that saves hours every week.
Onboarding first customers now.
