Shopware 6 can be connected to an ERP system in three ways: ready-made connectors from the Shopware Store, middleware platforms, or a custom-built integration via the Shopware API. Which route fits depends on your ERP system, the data to be synchronised and your processes. Typically, products, stock levels, prices, customers and orders are kept in sync.
Connecting the ERP or inventory management system is one of the most important building blocks of a professional online shop: without it, products, stock levels and orders have to be maintained twice – a time sink and a frequent source of errors. Shopware 6 is well equipped for this, as its API-first architecture exposes all shop functions through documented programming interfaces.
Implemented properly, the integration noticeably automates day-to-day business: new products from the ERP appear in the shop automatically, orders flow into the ERP without manual retyping, and stock levels stay consistent across channels – even when you sell on marketplaces in parallel. At the same time, the risk of overselling decreases because the shop always works with current stock levels. This reduces transfer errors and frees up capacity in your team.
Three routes to an ERP integration
- Ready-made connectors: For widespread systems such as JTL-Wawi or common ERP solutions, ready-made plugins and connectors exist. They are comparatively quick to deploy but primarily cover standard processes.
- Middleware platforms: An integration layer between ERP and shop translates data formats and controls synchronisation centrally. Useful when several systems need to be connected – for example marketplaces or a PIM in addition.
- Custom integration: A tailor-made integration via the Shopware API also covers special processes – such as customer-specific prices from the ERP, complex variant logic or particular approval workflows.
Which of the three routes fits can be narrowed down with a few criteria: how widespread is your ERP system, and does a well-maintained connector exist for it? How far do your processes deviate from the standard? And how many additional systems should be connected in the medium term? For standard processes with a common ERP, a ready-made connector is often the most economical entry point. As soon as customer-specific pricing logic, special processes or a high degree of automation are required, a custom integration is usually the way to go – in return, it grows with your requirements.
Typically synchronised data includes product master data and variants, stock levels, prices and customer-group conditions from the ERP to the shop – and orders, customers and payment status in the opposite direction. Shipping and tracking information as well as invoice data can also be included in the synchronisation. A clear definition of which system is the leading source for which data (single source of truth) is essential. Without it, conflicts and inconsistent data sets arise that have to be cleaned up laboriously later.
What matters in practice
In our integration projects – for example with SAP Business One or Microsoft Dynamics – a few principles have proven their worth: synchronisation should be fault-tolerant and log transfer errors instead of silently losing data. Time-critical data such as stock levels needs shorter synchronisation intervals than master data. And the integration should be built in an update-safe way so that Shopware and ERP updates do not throw it off track.
The project usually starts with an analysis: which ERP is in use, which fields and processes need to be covered, what data volumes are involved? This results in a mapping concept that defines how the fields of both systems correspond to each other. After implementation, a test phase with real data follows on a staging environment before the integration goes live. An overview of the systems we connect can be found on our integrations overview.
In addition to the ERP, connecting your accounting is often worthwhile – for example via a DATEV integration for invoice and payment data. We are happy to clarify which combination makes sense for your system landscape in a free initial consultation.
