Notes from the Editorial Desk

Revenue ≠ profit

What you collect from a customer isn't what you keep. Subtract product costs, shipping, platform fees and all the other little surprises.

Margin vs. markup

Margin measures profit against the selling price. Markup measures it against cost. Confusing the two is a remarkably expensive hobby.

Beware the fine print

Marketplaces can charge category-specific fees, listing fees, advertising fees, payment processing and taxes. Check your actual fee schedule before setting prices.
