Car wash management spreadsheet: run your car wash from one Excel file

The Self-Service Car Wash Management System is an all-in-one car wash management spreadsheet for self-service car washes, jet wash bays and valeting sites. 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.
