A 20-sheet Excel system that runs a small product business: live dashboard KPIs, product catalog, sales orders, returns, purchase orders, stock movements, manufacturing, and profit tracking, all wired together with real formulas and no macros. Works in Excel and Google Sheets, and a blank copy is included so you can start empty.
Daily workflow: log every stock event in Movements. For Manufacture, add one positive row for the finished good made and one negative row per component consumed. Log customer orders on Sales Orders and returns on Returns; the check columns confirm each one against Movements. Set your business name, currency, and as-of date in Settings to make it yours in about five minutes.
Single-user license, pay once, yours forever. You may use it in commercial projects; redistribution or resale of the product itself is not permitted.
