How it works

How the InfiPlex Overstock integration works

Overstock.com has operated for over two decades as a place shoppers go specifically for clearance and closeout pricing, which today sits alongside Beyond, Inc.'s other retail brands as the liquidation-focused outlet in that portfolio. InfiPlex connects your Overstock.com seller account so orders pull into the same queue as every other channel, ship through your warehouse or a 3PL, and reconcile against one real-time inventory pool.

Flow diagram: Overstock.com sends new orders to the InfiPlex Order Management System about every 15 minutes. InfiPlex pushes tracking numbers and real-time inventory back to Overstock.com, and routes orders to Your Warehouses, 3PL / WMS Partners, Other Channels for fulfillment.

The InfiPlex Overstock.com sync rail: orders from your Overstock.com seller account flow into the OMS, ship from your warehouse or 3PL, and return tracking to Overstock.com — while inventory stays reconciled across every other channel in one pool.
