Why teams connect Blue Yonder WMS and Easypost

Keep the storefront in step with the back office: Easypost and Blue Yonder WMS share products, inventory, and orders in real time, in both directions.

Easypost runs the storefront and takes the orders; Blue Yonder WMS owns the item master, the stock on hand, and the finance behind every transaction. The two overlap wherever the same products, customers, and sales matter to both — and when re-keying or an overnight batch is what connects them, the store oversells items it can't ship, quotes prices finance never set, or leaves buyers waiting on status that already changed.

Stacksync syncs Tracker, Batch, CarrierAccount, Webhook in Easypost with Inbound shipments (ASNs), Purchase orders, Outbound orders, Shipments and shipment confirmations in Blue Yonder WMS field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Blue Yonder WMS, order and customer detail from Easypost — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Verify and normalize customer Addresses through EasyPost before they are saved to the CRM or OMS to cut failed deliveries and carrier address-correction surcharges.
  • 02 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.
  • 03 Mirror WMS inventory balances into a warehouse or ERP so planning and finance see the same on-hand numbers.
  • 04 Keep the item master aligned between the ERP and the WMS so new SKUs are receivable on day one.

Common sync patterns

One customer master

Where both systems keep customer records, a correction in either propagates to the other, ending dual maintenance.

Where Blue Yonder WMS is the inventory system of record: stock stays accurate

Available quantities from Blue Yonder WMS publish to Easypost, so the store shows what can actually ship and stops overselling.

New orders reach the back office

An order captured in Easypost creates the matching record in Blue Yonder WMS with customer, line items, and totals, so fulfillment and invoicing start without re-entry.
