Why teams connect Plex ERP and Shopware

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

Shopware 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 Customers, Orders, Order Line Items, Order Deliveries in Shopware with Shipments, Quality records, Parts, Inventory 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 Shopware — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Stream new `order` records with their `order_line_item`, `order_delivery`, and `order_transaction` rows into a warehouse or accounting system for revenue and fulfillment reporting.
  • 02 Sync `customer` records two-way with a CRM so support and marketing see order history while reps write updates back onto the account.
  • 03 Mirror purchase orders and receipts to accounting or planning tools.
  • 04 Feed quality and scrap data to dashboards supervisors check without logging into Plex.

Common sync patterns

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 Shopware, so the store shows what can actually ship and stops overselling.

New orders reach the back office

An order captured in Shopware creates the matching record in Plex ERP with customer, line items, and totals, so fulfillment and invoicing start without re-entry.

What you can sync between Plex ERP and Shopware

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.

Plex ERP objects Shopware objects How this pairing syncs
Customers Account records kept consistent with the sales team's CRM Customers Storefront customer accounts (`customer`) with addresses and group; synced two-way with a CRM or support tool. 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.
Quality records Checksheet and inspection data pulled into plant dashboards Order Line Items Per-order product rows (`order_line_item`); read alongside the order for revenue and fulfillment reporting. Quality records is specific to Plex ERP and Order Line Items to Shopware — each maps to any object or custom field on the other side.
Parts Item master records shared with CRM, e-commerce, and planning tools Order Deliveries Shipping records (`order_delivery`) carrying delivery state and tracking codes; written back from a 3PL or WMS. Parts is specific to Plex ERP and Order Deliveries to Shopware — each maps to any object or custom field on the other side.
Inventory On-hand balances and locations replicated for visibility outside the plant system Order Transactions Payment records (`order_transaction`) holding payment method and state; read to reconcile against a billing or finance system. Inventory is specific to Plex ERP and Order Transactions to Shopware — each maps to any object or custom field on the other side.
Production jobs Shop-floor work records combining ERP and MES data for output reporting Sales Channels Per-storefront configuration (`sales_channel`); used to scope and consolidate orders and customers across multiple storefronts. Production jobs is specific to Plex ERP and Sales Channels to Shopware — each maps to any object or custom field on the other side.
Sales orders Demand records written in from e-commerce or EDI channels and read out for fulfillment status Media Media assets (`media`) such as product images; referenced by id so file URLs and metadata sync into downstream catalogs. Sales orders is specific to Plex ERP and Media to Shopware — each maps to any object or custom field on the other side.

How changes propagate between Plex ERP and Shopware

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.

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

Shopware Plex ERP Sub-second propagation

DetectionShopware notifies Stacksync of record changes through webhook events. App-system webhooks on entity events (product.written, order.written, customer.written) deliver the changed record's primaryKey and updated field.

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

Rate-limit considerations

  • Plex ERP: Subject to the platform's API rate limits.
  • Shopware: No general throttle on Admin API entity endpoints; Shopware's RateLimiter guards only specific routes (login, oauth, password reset, guest order/contact) and is configurable on self-hosted stores.
