What you get

• reseller-inventory-profit-tracker.xlsx: blank workbook, tabs How to use, Dashboard, Settings, Inventory, Expenses
• reseller-inventory-profit-tracker-example.xlsx: the same workbook with 60 fictional items across 5 platforms and a year of expenses
• reseller-inventory-profit-tracker-guide.pdf: 1-page set-up guide
• README.txt, all in one ZIP

How it works

1. Settings: your platforms with the fee % each takes (typed in: check each platform's current fees and edit them), sourcing places, tax set-aside %, and the number of days after which stock counts as stale.
2. Inventory: one row per item: cost and date when you buy it, platform and list price when you list it, sold date, sale price and shipping when it sells.
3. Platform fee, profit, margin, days to sell and IN STOCK / SOLD fill in.
4. Dashboard: sales, revenue, fees, cost of goods, shipping, expenses and profit by month; each platform with profit and average days to sell; cash tied up in stock and stale items.

Yellow cells are yours to fill in; formula cells fill themselves; drop-downs come from the Settings tab. Fees are an estimate from the % you set, not a copy of your platform statement. Not tax advice; example numbers are fictional.

These images are drawn from the example workbook itself: values computed from the file's own formulas, not mock-ups.

Format

Excel .xlsx workbooks (no macros, no add-ins) and a 1-page PDF guide. Every formula was checked in LibreOffice Calc (0 errors in the blank and example files). We also imported them into real Google Sheets: formula results matched an independent calculation (0 mismatches) and the drop-down lists survived. To use one in Google Sheets, upload the .xlsx to Google Drive, open it and choose File > Save as Google Sheets. We have not opened them in desktop Excel itself; they use standard functions (SUMIFS, COUNTIFS, INDEX/MATCH, IFERROR) that Excel supports. If anything looks wrong, email support@tuper.app and we fix it or refund you.

Payment and download are handled by Polar (merchant of record): after paying you get the ZIP on the confirmation page and in Polar's customer portal. Single business use; please do not resell or share the files.
