Sound familiar?
You're running your business
on instinct and chaos.
Smart tradespeople are losing jobs, time, and money — not because of their craft, but because of their admin.
Quoting eats your week
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.
Scope of works takes hours
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.
Variations approved by memory
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.
No real all-in-one exists
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
Quote on site. Win the job before you leave.
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.
One platform · the whole job

Every step connected.

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.
