02
Every marketplace charges differently
Amazon, eBay, Etsy, Walmart, Shopify, and more — every marketplace prices fees differently. Your spreadsheet breaks every time one of them changes.
03
Pricing by gut feel
"This should leave something" is not a margin. Nobody tells you the minimum price you can afford to sell at.
Why not spreadsheets
A spreadsheet works. Until—
A spreadsheet is a ledger — not a margin engine.
- 1
When fees change, you have to rebuild the formulas. Marketplace templates come with source and effective date, and we update them when rules change.
- 2
You have to find last month's margin calculation again. Every calculation is saved as a snapshot — compare before and after listing.
- 3
To try another marketplace, you have to copy the sheet. Switch the template here and the same SKU recalculates instantly.
