Cross-list once, sell everywhere
Take a single listing and post it to eBay, Poshmark, Mercari, Depop, Etsy, Grailed, and Facebook Marketplace in one click. Auto-delists on sale to prevent double-selling. The de-facto standard for serious resellers.
Lighter, app-first cross-listing
Mobile-first cross-listing across 10+ marketplaces with photo editing, sale detection, and bulk actions. Generous free tier so you can try it before committing.
Cheapest USPS labels, period
Free software with USPS Commercial Plus pricing — the same wholesale rates Amazon and big merchants get. No monthly fee, no tier-based pricing, no upsells. Just print labels and pay USPS rates.
Scan books for instant resale-value lookups
Bluetooth scanner + iOS/Android app that pulls Amazon sales data and tells you in seconds whether a book at the thrift store is worth flipping. The standard tool for book resellers.
Live-stream auctions for collectibles
Leading platform for live-stream selling. Built for trading cards, sneakers, Funkos, comics, and other collectibles where buyers want to feel a sale happen. Built-in payment, shipping, and buyer protection.
The tools above are for selling. Below are guides to picking the right tool for checking what your stuff is worth.
