Windows software built around the work of eBay sellers.
Sellius is Windows desktop software for eBay sellers. It combines AI-assisted listing drafts, reusable listing templates, inventory management, bulk editing, eBay synchronization, sales, buyer messages, Best Offers and multiple seller accounts in one workspace.
What is Sellius?
Sellius is a seller application that runs on Windows. It brings the work of preparing listings, organizing inventory, revising active listings and handling buyer communication into one desktop workspace. The product is called Sellius, and its official website is selliuspro.com.
Built from experience selling on eBay
Sellius grew out of running an eBay business and spending roughly a decade working with traditional listing software. Repeated data entry, slow interfaces and disconnected tasks shaped the tools we wanted to build: editable drafts, reusable templates, bulk changes and account-aware inventory.
Choose a tool for each part of the workflow
| Seller task | Sellius tool |
|---|---|
| Prepare a draft from listing photos | Smart List AI |
| Reuse a format for similar items | Quick List templates |
| Find and organize listing records | Inventory management |
| Revise a group of active listings | Bulk Editor |
| Handle buyer questions and Best Offers | Messages & Offers |
| Track the order side of the business | Sales & Orders |
For different kinds of eBay inventory
The workflow supports sellers listing apparel, collectibles, books, magazines, home goods, electronics and other eBay inventory. Templates reduce repeated entry; photo-based drafts help with one-off items. The seller verifies the facts for each item before listing.
Your review stays part of the process
Smart List prepares drafts in Work In Progress. You can edit the generated text, check condition and item specifics, confirm business policies and decide when the listing is ready. Learn more about creating eBay drafts from photos or read the Sellius FAQ.
