Why teams connect Acumatica and Easypost

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

Easypost runs the storefront and takes the orders; Acumatica 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 Parcel, Rate, Tracker, Batch in Easypost with Journal Transactions, Projects, Opportunities and Cases, Customers in Acumatica field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Acumatica, order and customer detail from Easypost — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Create a Tracker for every outbound shipment and stream tracker.updated webhook events into Postgres or a warehouse so support and ops see live delivery status beside order records.
  • 02 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.
  • 03 Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
  • 04 Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.

Common sync patterns

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 Acumatica, 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.

What you can sync between Acumatica and Easypost

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Acumatica objects Easypost objects How this pairing syncs
Shipments Fulfillment documents read to update tracking in storefronts and CRMs. Shipment The central writable object: create with a to/from Address and Parcel, receive Rate options, then buy a label to get postage_label and tracking_code; retrieve and list with cursor pagination. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Projects Project cost and billing structures synced with delivery tools. Rate Carrier service and price options EasyPost generates on a Shipment; read-only - you select a rate id and buy it, you do not create or edit rates directly. Projects is specific to Acumatica and Rate to Easypost — each maps to any object or custom field on the other side.
Opportunities and Cases Built-in CRM records synced with external sales and support tools. Tracker Tracking for a shipment by tracking_code and carrier; create a Tracker to begin tracking, read status and tracking_details, and receive tracker.updated events via webhook as the parcel moves. Opportunities and Cases is specific to Acumatica and Tracker to Easypost — each maps to any object or custom field on the other side.
Customers AR master data synced with CRMs and billing tools. Batch Bulk shipment processing; create a batch, add or remove shipments, buy all labels at once, and generate a consolidated label or ScanForm for the day's orders. Customers is specific to Acumatica and Batch to Easypost — each maps to any object or custom field on the other side.
Vendors Supplier records aligned with procurement and AP automation. CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Vendors is specific to Acumatica and CarrierAccount to Easypost — each maps to any object or custom field on the other side.
Sales Orders Order documents created from e-commerce and CRM systems, read back for fulfillment status. Webhook Event subscriptions delivering an Event via HTTP POST on object changes; full CRUD (create, retrieve, list, update, delete) and the mechanism for near-real-time change delivery to Stacksync. Sales Orders is specific to Acumatica and Webhook to Easypost — each maps to any object or custom field on the other side.

How changes propagate between Acumatica and Easypost

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

DetectionAcumatica notifies Stacksync of record changes through webhook events. Push notifications configurable on data changes, plus polling on LastModifiedDateTime fields.

DeliveryEach detected change is written to Easypost through its API, with automatic retries and rate-limit backoff.

DeliveryEach detected change is written to Acumatica through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations
