There's no charge to switch to Seller Hub. You only need to continue paying for subscriptions that you already have, such as Selling Manager Pro or Basic (or higher) Store to access that additional functionality from Seller Hub.
If you're already selling on eBay, all of your listings -- drafts, scheduled, active, unsold, ended, templates -- and orders will appear in Seller Hub, so you can jump right in and continue business as usual.
Seller Hub brings together the features from Selling Manager, Selling Manager Pro, and My eBay Selling in a modern streamlined interface that's easier to navigate.
Beginning in Fall 2020, the following sellers will be moved into Seller Hub with no ability to opt out:
If you fall into any of these categories, we recommend that you get an early start with Seller Hub and familiarize yourself with the new interface and great new features.
