Website & Business Software2026Karo Kanaltechnik GmbH

Karo Kanaltechnik.

Website and custom business software for a drain cleaning company from Frauenfeld. The bilingual website has location pages for Zurich, Thurgau, St. Gallen and Appenzell and a price calculator. The software covers quotes, jobs, QR invoices, a technician view and a client portal; an iOS app is in progress.

The Challenge

Karo Kanaltechnik cleans, inspects and renovates drains and pipes and handles emergencies around the clock, from Frauenfeld across the cantons of Zurich, Thurgau, St. Gallen and Appenzell. Two things had to fit together: a website that gets found across this large area and brings in inquiries, and an operation that handles those inquiries without paperwork, from quote to on-site job to paid invoice.

Our Solution

The website offers a page for each service, location pages for towns in four cantons, pages for target groups such as property managers and municipalities, a public pricing page, a multi-step price and inquiry calculator, a glossary and a knowledge section, in German and English. Behind it runs custom business software. The office manages clients, scheduling, quotes and jobs there, and clients can accept quotes online. Invoices go out with a Swiss QR payment slip, and dunning runs in three stages. Technicians see their day and record time, job reports and photos. Clients get a portal with documents per property. An iOS app for use on the road is in progress.

Frequently Asked Questions

Why custom software instead of a standard solution for trades?+
Standard solutions cover the average. At Karo, quote, job scheduling, technician report, invoice and client portal are directly linked, and the software maps exactly these processes, without detours via spreadsheets or double data entry. The website and the software draw on the same data.
What is a QR invoice?+
The QR invoice is the Swiss standard payment slip. A QR code contains amount, recipient and reference, so customers can scan and pay the invoice with their banking app. Karo's software generates this payment slip automatically and links open invoices to the dunning process.
How does a company working in several cantons get found locally?+
With location pages only where the company really works, and with content that answers typical questions: prices, services and the emergency process. On top come pages for target groups such as property managers, municipalities and insurance claims, which have their own search queries.
