What our customers say
How fiber-optic contractors put their evenings back.
5.0
2 hrs/day saved“Before Vistwerk my Bauleiter spent two hours every evening rebuilding the day from memory into Excel. Now the crews send their WhatsApp voice notes from the trench and the Tagesbericht is basically written before he gets back to the office.”
4.9
40% faster billing“Our Aufmaß used to lag two months behind the actual work, so we were always waiting on payment. With the daily extraction we close the quantity survey the same week the trench is dug, and the invoices go out far sooner.”
4.8
5 crews, one system“We coordinate five subcontractor crews on the same Telekom rollout and every one of them used to document differently. Now every Bautagebuch comes out in the same format, so the audit trail finally holds together.”
4.7
Codes caught, not lost“I was sceptical that an AI could understand a crew member mumbling HK and NVt codes into a voice note in the wind. It transcribes the German correctly and flags anything it is unsure about for me to check, which is exactly what I wanted.”
4.9
Days to an afternoon“When Telekom asked for our completion notice and the photo documentation, we used to scramble for days digging through phones. The Fertigstellungsanzeige and Fotodokumentation are now assembled from what the crews already sent, so it took an afternoon.”
4.8
Weekly report in minutes“The Rückmeldedatei against the Bauzeitenplan used to be a Friday afternoon battle with the original Excel template. Vistwerk fills the actual progress straight into our own file, so the weekly report to the client is no longer a fight.”
5.0
Evenings back“As a smaller firm we do not have a back-office documentation team, it was always me at the kitchen table at night. Letting the crews just send photos and a quick voice note gave me my evenings back without losing the paper trail.”
4.9
Zero audit findings“We passed our last documentation audit without a single open finding, which has never happened before. Having every Bautagebuch and Aufmaß consistent across all our subcontractors is what made the difference.”
