Why teams connect Magento and Plex ERP

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

Magento runs the storefront and takes the orders; Plex 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 Categories, Orders, Customers, Inventory source items (MSI) in Magento with Parts, Inventory, Production jobs, Sales orders in Plex ERP field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Plex 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 Feed quality and scrap data to dashboards supervisors check without logging into Plex.
  • 04 Sync production and inventory data from Plex into a warehouse or Postgres for plant-level analytics.

Common sync patterns

Fulfillment and shipment status close the loop

As orders are picked, shipped, or invoiced in Plex ERP, tracking and status flow back to Magento 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 Plex ERP is the inventory system of record: stock stays accurate

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

What you can sync between Magento and Plex 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.

Magento objects Plex ERP objects How this pairing syncs
Customers Customer accounts and address book; synced two-way with a CRM so order history and contact records stay consistent. Customers Account records kept consistent with the sales team's CRM 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 Shipment and tracking records against orders; created or read to drive fulfillment status between Magento and a 3PL/WMS. Shipments Outbound logistics records synced to trading partners and tracking systems Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Categories Catalog tree and product-to-category assignments; written into Magento to control merchandising and read out for taxonomy reporting. Purchase orders Procurement records mirrored to accounting and planning systems Categories is specific to Magento and Purchase orders to Plex ERP — each maps to any object or custom field on the other side.
Orders Sales orders with line items, totals, and status; typically read out of Magento into a warehouse or ERP for fulfillment and revenue reporting. Suppliers Vendor records aligned with procurement and AP tools Orders is specific to Magento and Suppliers to Plex ERP — each maps to any object or custom field on the other side.
Inventory source items (MSI) Per-source stock quantities under Multi-Source Inventory; written from a WMS/ERP so storefront stock matches the warehouse. Quality records Checksheet and inspection data pulled into plant dashboards Inventory source items (MSI) is specific to Magento and Quality records to Plex ERP — each maps to any object or custom field on the other side.
Invoices Invoice documents tied to orders; read out for finance and revenue recognition, or created via the sales API when billing downstream. Parts Item master records shared with CRM, e-commerce, and planning tools Invoices is specific to Magento and Parts to Plex ERP — each maps to any object or custom field on the other side.

How changes propagate between Magento and Plex 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.

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

Plex ERP Magento Interval-based propagation

DetectionStacksync polls Plex ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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

Rate-limit considerations

  • 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.
  • Plex ERP: Subject to the platform's API rate limits.
