Multichannel Reseller is a free guide for resellers who list the same items on more than one marketplace. Every fee on it comes from the marketplace's own fee page, with the date it was checked, and every net figure is arithmetic you can redo.
The short version
- Crosslist to move items that sit, not to rescue weak listings. A weak listing fails on four marketplaces at four times the work.
- Build the delisting routine before the second marketplace. One inventory record, a SKU on every item, and delisting within minutes of a sale.
- Compare fees on what they're charged on. eBay's 13.6% applies to the item, the shipping and the tax. Poshmark's 20% applies to the sale price alone.
- Two marketplaces is a workable rule of thumb for a solo seller. There's no prize for being everywhere, and a canceled order costs you on the marketplace where it happens.
Where to start
Start with the fee comparison to choose where to list, the calculator to price an item, or the delisting routine if you already crosslist.
- Deciding where to list? Marketplace fees compared has eight marketplaces' US seller fees and what you keep at $10 to $100.
- Pricing one item? The net proceeds calculator shows what it nets on three marketplaces side by side.
- Already crosslisting? The delisting routine and what a canceled order costs on eBay, Poshmark and Mercari.

Disclosure Multichannel Reseller is published by the team behind FlowLister, an AI eBay listing tool. FlowLister turns item photos into complete eBay listings: title, description, category, item specifics, price and shipping, in about 30 seconds. It publishes to eBay through eBay's official Trading API. Its crosslisting add-on posts eBay listings to Poshmark, Mercari and Depop. FlowLister does not support Vinted, Etsy, Shopify or Facebook Marketplace yet, and no dates are set. It's AI, so check each listing before you publish. We make it, so read this as a disclosure, not a review. Nothing on this site needs it.
