Why teams connect Easypost and Dynamics 365 Business Central

Keep the storefront in step with the back office: Easypost and Dynamics 365 Business Central share products, inventory, and orders in real time, in both directions.

Easypost runs the storefront and takes the orders; Dynamics 365 Business Central 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 Webhook, Shipment, Address, Parcel in Easypost with Journals, Dimensions, Payments, Customers in Dynamics 365 Business Central field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Dynamics 365 Business Central, 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 Sync vendor and purchase order data with procurement or AP automation tools.
  • 04 Create sales orders in Business Central automatically from e-commerce or CRM order records, and sync fulfillment status back.

Common sync patterns

Fulfillment and shipment status close the loop

As orders are picked, shipped, or invoiced in Dynamics 365 Business Central, tracking and status flow back to Easypost so buyers see accurate updates.

One customer master

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

Where Dynamics 365 Business Central is the inventory system of record: stock stays accurate

Available quantities from Dynamics 365 Business Central publish to Easypost, so the store shows what can actually ship and stops overselling.
