Why teams connect Epicor ERP and Magento

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

Magento 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 Invoices, Shipments, Carts / quotes, Products in Magento with Customers, Suppliers, Parts, Sales orders 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 Magento — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Master Products, prices, and Category assignments in an ERP or PIM and write them into Magento's catalog by SKU.
  • 02 Keep MSI inventory source-item quantities aligned between a WMS/ERP and Magento so storefront stock matches the warehouse.
  • 03 Sync Epicor customers and AR invoices into a CRM so sales sees order history and credit status without ERP logins.
  • 04 Push won opportunities from the CRM into Epicor as sales orders and sync order status back.

Common sync patterns

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

Available quantities from Epicor ERP publish to Magento, so the store shows what can actually ship and stops overselling.

New orders reach the back office

An order captured in Magento creates the matching record in Epicor ERP 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.

What you can sync between Epicor ERP and Magento

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.

Epicor ERP objects Magento objects How this pairing syncs
Customers Master records synced with CRM accounts so sales and the ERP agree on ownership and credit status. Customers Customer accounts and address book; synced two-way with a CRM so order history and contact records stay consistent. 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.
Shipments Fulfillment confirmations synced to customer portals and commerce systems. Shipments Shipment and tracking records against orders; created or read to drive fulfillment status between Magento and a 3PL/WMS. 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.
Quotes Estimates that pair with CRM opportunities during the sales cycle. Invoices Invoice documents tied to orders; read out for finance and revenue recognition, or created via the sales API when billing downstream. Quotes is specific to Epicor ERP and Invoices to Magento — each maps to any object or custom field on the other side.
AR invoices Billing records surfaced in CRM or finance tools for collections visibility. Carts / quotes Active and guest carts (quotes) with items and totals; read for abandoned-cart analysis (not available on the Cloud Service subset). AR invoices is specific to Epicor ERP and Carts / quotes to Magento — each maps to any object or custom field on the other side.
Bills of materials Methods of manufacturing read for costing and planning integrations. Products Catalog items keyed by SKU; carry created_at/updated_at for incremental polling and are written two-way from a PIM or ERP into the storefront. Bills of materials is specific to Epicor ERP and Products to Magento — each maps to any object or custom field on the other side.
Suppliers Vendor masters kept aligned with procurement and AP automation tools. Configurable / variant products Parent configurable products link to simple product variants by attribute; synced so size/color SKUs and their prices stay aligned with source systems. Suppliers is specific to Epicor ERP and Configurable / variant products to Magento — each maps to any object or custom field on the other side.

How changes propagate between Epicor ERP and Magento

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.

Epicor ERP Magento 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 Magento through its API, with automatic retries and rate-limit backoff.

Magento Epicor ERP Sub-second propagation

DetectionMagento notifies Stacksync of record changes through webhook events. Polling with searchCriteria filters on updated_at (catalog, sales, and customer entities carry created_at/updated_at).

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

Rate-limit considerations

  • Epicor ERP: Subject to the platform's API rate limits and per-tenant throttling on Kinetic cloud deployments.
  • Magento: No fixed request-per-minute cap on PaaS/on-prem; responses page via searchCriteria pageSize/currentPage under a default maximum page size of 300 (Web API Input Limits), with /async/bulk endpoints for large writes.
