Why teams connect DEAR Inventory and Easypost

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

Easypost runs the storefront and takes the orders; DEAR Inventory 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 Address, Parcel, Rate, Tracker in Easypost with Sale orders, Purchase orders, Customers, Suppliers in DEAR Inventory field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from DEAR Inventory, 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 Sync stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.
  • 04 Push sale orders from a storefront or CRM into DEAR for fulfillment without manual re-entry.

Common sync patterns

New orders reach the back office

An order captured in Easypost creates the matching record in DEAR Inventory 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.

Fulfillment and shipment status close the loop

As orders are picked, shipped, or invoiced in DEAR Inventory, tracking and status flow back to Easypost so buyers see accurate updates.
