Why teams connect Easypost and Epicor ERP

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

Easypost runs the storefront and takes the orders; Epicor ERP 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 Shipment, Address, Parcel, Rate in Easypost with Shipments, Bills of materials, Customers, Suppliers in Epicor ERP field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Epicor ERP, 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 Push won opportunities from the CRM into Epicor as sales orders and sync order status back.
  • 04 Mirror parts, on-hand inventory, and job status into a reporting database for shop-floor dashboards.

Common sync patterns

One customer master

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

Where Epicor ERP is the inventory system of record: stock stays accurate

Available quantities from Epicor ERP 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 Epicor ERP with customer, line items, and totals, so fulfillment and invoicing start without re-entry.

What you can sync between Easypost and Epicor ERP

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.

Easypost objects Epicor ERP objects How this pairing syncs
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. Shipments Fulfillment confirmations synced to customer portals and commerce systems. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Jobs Production jobs whose status feeds shop-floor dashboards and delivery-date updates. CarrierAccount is specific to Easypost and Jobs to Epicor ERP — each maps to any object or custom field on the other side.
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. Quotes Estimates that pair with CRM opportunities during the sales cycle. Webhook is specific to Easypost and Quotes to Epicor ERP — each maps to any object or custom field on the other side.
Address Origin and destination locations; create, retrieve, and list, plus address verification (delivery and residential) to normalize and validate addresses before they are saved downstream. AR invoices Billing records surfaced in CRM or finance tools for collections visibility. Address is specific to Easypost and AR invoices to Epicor ERP — each maps to any object or custom field on the other side.
Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Bills of materials Methods of manufacturing read for costing and planning integrations. Parcel is specific to Easypost and Bills of materials to Epicor ERP — each maps to any object or custom field on the other side.
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. Customers Master records synced with CRM accounts so sales and the ERP agree on ownership and credit status. Rate is specific to Easypost and Customers to Epicor ERP — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Epicor ERP

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.

Easypost Epicor ERP Sub-second propagation

DetectionEasypost notifies Stacksync of record changes through webhook events. Webhooks deliver an Event via HTTP POST on object changes (e.g.

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

Epicor ERP Easypost Interval-based propagation

DetectionStacksync polls Epicor ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change-date fields.

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

Rate-limit considerations

  • Easypost: Fixed 5 requests/second on index (list) endpoints plus a dynamic load-based limiter protecting buy and rate operations; exceeding either returns HTTP 429 Too Many Requests.
  • Epicor ERP: Subject to the platform's API rate limits and per-tenant throttling on Kinetic cloud deployments.
