We build one system for tradespeople — so you can stay on site

Most tradespeople run their business from the van, the scaffolding and the kitchen table in the evening. Quotes in one tool, invoices in another, hours on a slip of paper, calls that slip away. We brought it all into one place — and let an AI handle the boring parts.

Why we do it

Software should work for the tradesperson — not the other way round

We’ve seen too many systems that promise a lot and end up as one more thing you have to remember to update. So we built the opposite: a system that takes the call when you can’t get to it, drafts the quote and posts the invoice to your books — so you stay in control with the full overview on one screen.

Everything is developed close to real tradespeople who use it every day. That’s why it feels like a good piece of kit — not like software.

What we stand for

Trades only

We do one thing: software for tradespeople. That’s why the language, the tasks and the flow fit the way you actually work.

Built with tradespeople

Every feature is shaped by real owners and crew who use it on site every day.

A real person on the line

When something’s on fire, you reach a person who knows the system — right away.

Honest pricing

One flat price, everything included. No hidden fees, and we never cut you off — you only pay for genuine overage.

The people behind it

Meet the team

We’re a small Danish team. Frederik and Lucass built every line of the system themselves — because we were tired of watching skilled tradespeople drown in quotes, calls and invoicing hassle. Peter handles partnerships and customer relations. When you call, it’s a person who picks up. Not a call centre.
