ShipStation + Overstock Integration: clearance volume, shipped at clearance speed
Overstock.com moves clearance and closeout inventory in volume, and those orders need to get out the door efficiently. InfiPlex pulls your Overstock orders automatically, routes each to the right warehouse, and sends them into ShipStation so labels print on your carriers and rates — with tracking posting back to Overstock immediately.
How it works
How this integration works
Clearance selling is a throughput game: thinner margins reward efficient fulfillment, and closeout stock is by definition finite, so overselling is expensive. InfiPlex pulls Overstock orders into the same queue as everything else you sell, keeps the shared inventory count accurate in real time as closeout lots sell down, and hands each order to ShipStation where your carriers, rates, and automation rules do the shipping. Tracking flows back to Overstock automatically the moment a label prints.
