By role

For the Nachunternehmer whose crews already work in WhatsApp

Leon, Necmettin, and OMTG send voice notes, photos, and a line of text from the Gehweg the way they always have. Nothing new gets installed on the truck, nobody sits through training, and the evening write-up that used to eat an hour mostly disappears. Vistwerk turns what they already send into the report — and names your firm correctly as Ausführende every time.

What your crew already sends — German and Turkish, voice or text

Your crews do the work twice

First on the Gehweg, then again at the kitchen table — re-typing what they already said into a report so the GC can file it.

Yet another app to refuse

Field crews won't adopt a new tool, and you shouldn't have to make them. The phone and WhatsApp they already use is the whole interface.

German and Turkish in the same chat

Necmettin's lines are Turkish, Leon's are German, often in one thread. A tool that only handles German loses half of what was said on site.

Credited wrong, or not at all

When the GC merges the day, it's easy for your firm's meters to land under the wrong sub — or for SunBau to go unnamed where it should read Ausführende.

What changes with Vistwerk

The crew keeps sending WhatsApp. The admin and the credit sort themselves out.

No new app

WhatsApp stays the only thing on the truck

Voice notes, photos, and text go to the same number as always. Whisper auto-detects German or Turkish per message, so a Turkish voice note is read as accurately as a German one — no app, no login, no training day.

  • Same WhatsApp number, same habit
  • German and Turkish transcribed per message
  • HK and NVt codes matched against the project schedule

Voice, photo, text — straight from the Gehweg
Credited

Your firm reads as Ausführende, every time

Each message is tagged to your firm before it ever reaches a document, so your meters land in your section of the sub-grouped Tagesbericht and your name carries through to the Fertigstellungsanzeige as Ausführende.

  • Your meters stay in your sub's section
  • Named as Ausführende on the filing
  • Original audio and photo attached, so nothing is in dispute
