FAQ

Excel or Google Sheets?: Built for Excel (2016+) and LibreOffice. Google Sheets imports it with formulas intact, minus minor formatting.
Does it include sales tax and Promoted Listings ads?: Yes — eBay fees its percentage on shipping and tax too, and there's an ad-rate column per row. Most free spreadsheets skip both.
What if eBay changes fees?: Update the Rate Card sheet — every formula references it. We also keep the site's fee tables updated; check margingauge.com when in doubt.
Refunds?: If the workbook doesn't work for you, email hello@margingauge.com within 14 days for a full refund.
