If you sell on multiple eBay accounts you can tie them all into the one SellerExpress account. SellerExpress offers support for multiple major eBay marketplaces including eBay.com, eBay.co.uk, eBay.ie and many more.
You can also sell on multiple accounts linked to a single eBay tied to a single SellerExpress account. For example, you can sell using multiple eBay.co.uk stores under a single SellerExpress account.
NB. You can have a maximum of three eBay accounts per national eBay marketplace.
