From sourcing to shipment, Refynd is designed around the real reseller workflow.

Refynd is an early-stage concept for people who buy and resell across platforms like Vinted, eBay, Marktplaats and Facebook Marketplace. The goal is to make resale less manual: understand what is in stock, what is worth relisting, which offers to accept, when demand is rising, and where money is actually being made.

Inventory intelligence Track stock, quantities, seasonal demand, item costs, photos and listing quality.

Inbox automation Manage buyer conversations, sold-item cleanup, offer rules and previous transaction history.

Pricing and offers Set acceptance and rejection ranges, monitor demand, and act before stale listings sit too long.

Bundle profitability Split bundle purchases into per-item costs so resale margin calculations stay useful.

Relisting workflows Automatically relist multi-quantity items, refresh old listings and keep marketplace stock moving.

Shipment tracking Collect shipment updates, surface delays, and keep fulfilment admin from becoming a spreadsheet mess.
