BOS was built by people who needed a better way to manage their work and stay organised. After trying and testing plenty of other apps, we kept finding useful features spread across different systems — but never everything we needed in one place.
So we built BOS to bring those everyday tools together: jobs, customers, bookings, quotes, invoices and the figures behind the work. One app to help small businesses stay on top of the day-to-day.
