Garage management spreadsheet: run your garage from one Excel file

The Garage Management System is an all-in-one garage management spreadsheet for independent garages, MOT centres and mobile mechanics. Track sales and VAT, chase unpaid invoices, run your stock take, plan the staff 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.
