Run your entire product business from one spreadsheet.

If you make or sell physical products, you already know the problem: your inventory lives in one app, your invoices in another, your production costs in a notebook, and your actual profit is a guess. Product Business OS puts all of it in one connected Google Sheets / Excel workbook, so every number updates itself.

Log a purchase, a sale, or a production batch once — inventory, supplier balances, client balances, and your financial reports all update automatically. No manual re-entry, no separate apps, no end-of-month scramble.

Built for: Etsy and Shopify sellers, handmade and craft businesses, small manufacturers, and anyone selling physical products who's outgrown a plain checklist or basic tracker.

Why it works

✅ One system instead of five apps
✅ Real formulas — SUMIFS, INDEX/MATCH — every number recalculates itself
✅ Works in Google Sheets (free account) or Excel 2021 / Microsoft 365 or later
✅ No macros, no add-ons, no subscription

Getting started

Takes about 20 minutes to set up. Add your suppliers and clients, list your inventory, and start logging — the Setup & Instructions tab walks you through it step by step.
