Built for the trade, not for an office.

Most software was made for someone sat at a desk. Checker was built for someone under a boiler, on a roof, or in a van between jobs. It works the way you actually work.

15 tools, one app.

Every part of the business, joined up. Add a customer once and they show up everywhere – quotes, jobs, certificates, reminders, the lot.
