The Plumbing & Heating Business Management System is an all-in-one plumbing business spreadsheet for plumbing and heating businesses. Log every job or sale, chase unpaid invoices, run your stock take, plan the rota, keep on top of daily checks, certificates and risk assessments, and see your profit on a live dashboard. It costs £15 once, with no subscription and no app, so you keep your own data in a file you already know how to use.

- One-off £15, not a monthly fee
- Works offline in Excel you already own, or in Excel online with your team
- Your data stays in your file, not on someone else's platform
