More control, more opportunities
ShipStation is the fulfillment engine behind Kaizen Seller's Direct-to-Consumer shipping workflow. Orders from any connected marketplace flow into ShipStation for label generation, then tracking automatically syncs back to the originating channel.
Multi-Channel Order Routing
Amazon, eBay, BigCommerce, and Google Shopping orders are routed into ShipStation as a single fulfillment queue.
Multi-Carrier Label Generation
Generate shipping labels with USPS, UPS, and FedEx based on package weight, dimensions, and destination.
Address Validation
Buyer shipping addresses are validated through ShipStation before label creation to prevent undeliverable shipments.
Automatic Tracking Sync
Tracking number, carrier, and ship date are automatically pushed back to the originating marketplace (Amazon, eBay, BigCommerce, Google Shopping) within minutes of label creation.
