Why teams connect Easypost and Manhattan Associates WMS

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

Easypost runs the storefront and takes the orders; Manhattan Associates 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 CarrierAccount, Webhook, Shipment, Address in Easypost with Items, Shipments & LPNs, Receipts, Locations & Zones in Manhattan Associates WMS field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Manhattan Associates WMS, order and customer detail from Easypost — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.
  • 02 Pull Shipment, Rate, and Refund records into a warehouse to report shipping cost per carrier and service and reclaim postage on labels that were never scanned.
  • 03 Stream ship confirmations and tracking to the ERP and CRM so customer service answers from live data.
  • 04 Mirror inventory positions across the distribution network into a central warehouse for network-level visibility.

Common sync patterns

Where Manhattan Associates WMS is the inventory system of record: stock stays accurate

Available quantities from Manhattan Associates 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 Manhattan Associates WMS with customer, line items, and totals, so fulfillment and invoicing start without re-entry.

One product catalog

Where both systems keep item records, SKUs, descriptions, and attributes stay aligned so the store and the back office describe the same product.
