Sell More Products is a set of plain guides for people who make or source products and sell them online: which channel fits which product, what each platform takes from a sale, how to price, ship, photograph and describe what you sell, and how to handle returns and reviews.
Every fee and rule comes from the source that sets it: Etsy’s and Amazon’s own policy and help pages, Etsy’s annual report, Shopify’s pricing page, the Federal Trade Commission, the IRS, the Consumer Product Safety Commission, the U.S. Postal Service and the U.S. Census Bureau.
We are not affiliated with any platform and nobody pays to be mentioned. Worked examples are plain arithmetic on published rates. Shopify shows its prices by country, so check the page for yours. The Payout check on this site runs in your browser.
Platforms change their fees and rules, sometimes several times a year. Before you commit stock or money, read the current page.
