Facebook Seller App

Meta launched the Facebook Seller App on July 24, 2026 — timed to Facebook Marketplace's tenth anniversary. It's free, currently available on the US App Store for iOS, with Android and a web version in testing. This book explains exactly what it is and what it actually does, verified directly against Meta's own published materials.

The app's core feature is AI-powered listing creation built on Meta's own Llama 4 multimodal model. Upload a photo, and it generates a draft title, description, category, and suggested price automatically. The book covers what that AI tool actually does versus what it claims to do, including an honest assessment of where it's accurate, where it misses, and what you still need to verify before publishing any listing.

Beyond AI listings, the app adds bulk listing for multiple items at once, a unified inbox that groups buyer messages by item instead of mixing them into regular Messenger, real inventory management for viewing, editing, relisting, and removing listings from one place, and a performance dashboard showing views, clicks, message threads, and completed sales. Facebook Verified — a free, selfie-based seller identity check separate from the paid Meta Verified subscription — launches alongside it.

Chapter 5 covers what this actually means for eBay sellers and online resellers with sourced, honest context: eBay's stock fell 3.7 percent the day Seller launched, confirmed across six independent financial sources. eBay's fee structure runs roughly 13 to 15 percent in final value fees versus Meta's advertising-based model. And eBay already has its own comparable AI listing tool, called Magical Listing — this app enters a competitive space, not an empty one.
