Wonder Lister is an eBay listing platform which allows users to create, edit, duplicate, submit, and relist product listings. Included are tools for automation, sales reporting, order management, shipment tracking, consignor payouts, and data export for eCommerce sites including Shopify, Amazon, Etsy, and more. Wonder Lister allows users to create and save listings, and submit them to eBay at a later date, such as during a free listing promotion. The built-in scheduler can be used to automate listing and relisting of products, at dates and times selected by users. User-defined and custom information and item specifics fields can be added into listings, and users can create their own ad templates with tags. 'Best Offers' listings can be set up, with user-defined auto-accept and auto-decline thresholds. Wonder Lister can also be used to manage listings in bulk. Multiple products can be bulk listed based on the latest listing for each individual product, listings can be bulk duplicated, edited, and saved or sent to eBay, multiple fields in multiple listings can be edited at the same time, item specifics can be changed in bulk, and listings eligible for insertion fee credit can be relisted in bulk.
