Reseller profit tracker: see which platform actually pays

Revenue is not profit. Once platform fees, shipping and the price you paid for the item are taken out, the platform that feels busiest is not always the one that pays best. This spreadsheet shows the difference per platform and per month.

What it does

• One log for every buy and sale: a 300-row sales log in one place instead of one sheet per platform.
• Fees filled in for you: six platform presets (Whatnot, eBay DE, Vinted, Depop, Kleinanzeigen, Poshmark), checked on 14 Oct 2026 and editable, plus two free rows for any other platform. Platforms change fees, so check the yellow Settings cells against the platform's current fee page.
• Net profit, margin and ROI for each sale, with a one-off "Fee override" for sales that differ from the preset.
• Dashboard by platform and month so you can compare where the money actually stays.
• DAC7 counter per platform: in the EU, platforms report sellers who reach 30 sales or EUR 2,000 on that platform in a calendar year. The tab counts this for each platform separately. It is a counter, not tax advice.
• German and English interface switch, any currency symbol, and a one-page Quick Start in both languages.

How it works

1. Check the fee presets in Settings and adjust anything that has changed.
2. Enter each item: what you paid, what it sold for, shipping and the platform.
3. Read profit, margin and ROI per sale, and the dashboard for the platform and month view.

Why one workbook for all platforms

If you sell in more than one place, single-platform trackers force you to compare numbers across files. The All Platforms version costs $9; the same shop also sells single-platform versions at $5 each (Whatnot, eBay DE, Vinted, Depop, Kleinanzeigen, Poshmark) if you only need one.

Good to know

It is an .xlsx file with standard formulas and no macros, built for Excel and Google Sheets and checked in LibreOffice. The workbook does not connect to any platform, so you enter your sales yourself. Platform names are used only to describe compatibility; they are trademarks of their owners and Size Run Studio is not affiliated with or endorsed by any platform. Purchases include a 30-day money-back guarantee on Gumroad.
