how do roofers and carpenters use whatsapp to create legally compliant construction documentation

Question

Accepted Answer

Roofers and carpenters use WECAVIS to convert a WhatsApp photo and a short voice or text message into a legally compliant, timestamped PDF report in under 30 seconds - no app installation, no login, and no form-filling required.

Four document types cover every legal protection a trade needs:

Tagesbericht (daily report): The worker photographs completed work, sends a voice note, and WECAVIS AI (powered by Anthropic and xAI) transcribes it from over 30 languages into German, capturing hours worked, materials used, GPS location, and site conditions in a minute-precise PDF.
Behinderungsanzeige (obstruction notice): Documents site disruptions under Section 6 VOB/B, creating a legally valid record the moment the obstruction occurs.
Gefahrenmeldung (hazard notice): Captures safety hazards with photo evidence and an automatic severity classification - minor, moderate, severe, or critical.
Materialanforderung (material request): Tracks every order with a timestamped record supporting post-calculation (Nachkalkulation).

All reports are automatically assigned to the correct project and stored in the WECAVIS web portal. WECAVIS starts at 99 EUR per month with no hardware or training costs.
