E-Commerce: ERP Integration

ERPIntegration

Without a reliable ERP integration, you manage prices, inventory, and orders twice over — error-prone, time-delayed, and hostile to scale. We integrate your Shopware shop with SAP, Microsoft Dynamics, Xentral, Sage, or other ERP systems so data syncs in real time and manual transfers become a thing of the past. Your shop always works with current data; your team gains time for tasks that actually create value.

Challenges you'll recognise

  • Inventory and prices in the shop diverge from the ERP because manual transfers are time-delayed or contain errors.
  • New orders must be manually or batch-exported to the ERP — time-consuming and error-prone at high order volumes.
  • An ERP outage has previously blocked the checkout or caused data loss with orders.

Bidirectional Sync

Prices and inventory flow from ERP to shop; orders flow from shop to ERP. We implement this bidirectional synchronisation with real-time or event-based updates so customers always see current availability and your ERP is informed immediately about new orders. No more time-delayed batch imports.

Field Mapping & Transformation

ERP data structures and shop data structures rarely align. We create a complete field mapping, implement data transformation logic, and handle edge cases like product variants, price groups, and multi-warehouse inventory consolidation. The mapping document is transparent and makes every decision traceable.

Error Handling & Monitoring

In a bidirectional integration, conflicts and errors will eventually arise — a stale inventory in the ERP, an order that couldn't be transferred. We implement robust error handling with retry logic, error queues, and alerting so no order ever silently disappears and you always have visibility into sync status.

Performant Architecture

ERP integrations must be performant without blocking the shop checkout. We use asynchronous processing and message queues so ERP communication runs in the background — a temporarily unavailable ERP does not interrupt the order process. Messages are stored persistently and processed upon restoration.

Good to know

  • Real-time inventory reduces cancellations

    When inventory data is synchronised with a delay, customers can order items already sold out in the ERP. Real-time or short-interval synchronisation reduces the cancellation rate and protects the customer experience.

  • Async queue decouples ERP and checkout

    When ERP communication happens synchronously in the checkout process, the ERP determines checkout load time. Asynchronous message queue architecture decouples both systems — the checkout confirms immediately; the ERP is informed independently.

  • Field mapping must be documented

    Undocumented mapping decisions are a frequent cause of later integration problems. When nobody knows why a field was mapped a certain way, debugging becomes expensive. A maintained mapping document is a mandatory part of any serious ERP integration.

Frequently asked questions

Which ERP systems do you integrate?
We integrate common ERP systems including SAP (ECC and S/4HANA), Microsoft Dynamics 365, Xentral, Sage, Lexware, and custom ERP systems with their own API. For systems without direct API support, we work with file-based interfaces or middleware solutions.
Does synchronisation run in real time or as a batch?
That depends on the requirements and the capabilities of the ERP system. Inventory and price changes can be transferred in real time via webhook when the ERP supports it. For ERP systems without event support, we implement short-interval batch synchronisation with configurable intervals.
What happens if the ERP is temporarily unavailable?
New orders are stored in a persistent queue and automatically transferred once the ERP is available again. The shop checkout continues uninterrupted in the meantime. You receive an alert when the connection is interrupted and again when it is restored.
