The all-in-one platform for Swiss tradespeople. Quotes in minutes, not days. WhatsApp + email in one inbox. Change orders with a digital paper trail.
Sound familiar?
Smart tradespeople are losing jobs, time, and money — not because of their craft, but because of their admin.
Site visit. Manual calculations. Formatting. Sending. Follow-up. By the time it's out, the client has already signed with someone faster. You didn't lose on price — you lost on speed.
Writing up what needs to happen, for which team, in what order — takes hours every job. Then they do it wrong anyway because the brief was unclear or they didn't read it.
Client asks for extra work on-site. Team does it. No written approval. You invoice for it. Client says they never agreed. You have no proof — and you eat the cost.
WhatsApp. Three email accounts. A quoting tool. An invoicing app. Paper forms. You've tried stitching it together. It never fully works. Things fall through the gaps every single job.
The wedge · on-site quoting
Photograph the room, pick the finish, and the fixed price builds itself from live supplier prices. Your client signs in about 20 minutes — while a competitor is still booking a second visit.

We were running our business on WhatsApp, three email accounts, and instinct. Every quote was taking two or three days. Now we quote on-site in 20 minutes, every change order is signed digitally, and invoicing is automatic. We won two jobs last month that we would have lost before — because we were faster.
