Free tools and guides for Mercari sellers — starting with what you keep after fees.
The 10% selling fee on price plus buyer-paid shipping — and what you actually earn on a Mercari sale.
Open the tool →Mercari limits accounts for prohibited items or conduct, repeated violations, risky activity or pending verification — and tells you why by in-app message and email. How to respond and avoid the next one.
Mercari doesn’t verify everyone at sign-up — it asks at certain limits: to sell above the $2,000 price limit, when you become a high-volume seller under the INFORM Consumers Act, and for a W-9. What each needs, and the 10-day deadline that can suspend selling.
On Mercari, buyers can bundle several of your items into one purchase or one offer (up to $2,000), shipped in one box. How you accept, counter or decline a bundle offer within 24 hours, how bundle shipping is calculated and who pays, Shipping Protection, and why partial returns aren’t allowed.
On Mercari, a buyer’s cancellation request goes through automatically if you don’t confirm shipment within 24 hours. Cancelling yourself can cost 5% of the item price (up to $25), and frequent cancellations can limit your account.
On Mercari, buyers can only get a mandatory return within 72 hours of delivery, for items significantly not as described, damaged in shipping or counterfeit. “Doesn’t fit” and “changed my mind” are your choice. Labels, the 50-pound rule, refund timing and what to do if a return arrives damaged.
On Mercari you choose a prepaid label (USPS, UPS or FedEx, flat rates across all 50 states, up to $200 Shipping Protection) or ship on your own with tracking. Who pays, size and weight limits, the 3-business-day rule, and the October 2026 rate update.
