DSCO (recently acquired by Rithum) is a 3PL solutions provider that Poshmark has integrated with to allow for automated Order, Shipment Tracking, and Inventory Feeds between 3PLs and Poshmark.
We do not currently have an active Product Feed live with the DSCO system, so DSCO-connected sellers will need to use Poshmark's bulk upload template to create and edit listings in their closet.
