Shopware is a flexible e-commerce platform for B2B and B2C with a strong focus on the DACH market. SAP Business One is an ERP system for the smaller mid-market and covers finance, sales, purchasing, and warehouse management.
The Shopware SAP Business One integration connects e-commerce and ERP in real-time. Orders automatically become sales orders, inventory levels flow into the shop, prices remain consistent. The result: seamless order-to-cash without media breaks, no overselling, and less manual work.
This integration solves typical problems between shop and ERP. Here are six scenarios from real-world practice.
Automatically create orders. Every shop order is created as a sales order in SAP Business One, with all line items, customer data, shipping method, and payment method. Finance and warehouse work with the same data the customer entered at checkout.
Synchronize inventory levels. Availability from the ERP is displayed in real-time in the shop. Products that are not in stock are marked or hidden. This prevents overselling and disappointed customers.
Use prices from the ERP. Price lists, customer group conditions, and tier prices come from SAP Business One. The shop always displays current prices, even for B2B customers with individual agreements.
Synchronize customer master data. New shop customers are created as business partners in SAP Business One. Existing customers are recognized and matched. Addresses, email, and phone numbers are available in both systems.
Display delivery status in the shop. Tracking information from the ERP or logistics becomes visible in the customer account. Customers see when their order was shipped without contacting support.
Connect multiple Shopware instances. Many companies operate a B2C shop and a B2B shop. MARINI synchronizes both with the same ERP, distributes data securely, and orchestrates complex workflows in real-time.
The use cases on this page are not theoretical, but implementing them requires experience. You can set up integration and data management yourself through MARINI’s no-code interface, or have our team configure it for you. For implementation in your systems, we work collaboratively with you and your service providers. If you don’t yet have a suitable service provider, we’re happy to recommend an appropriate partner from our network.

Prices always up to date. Marketing plans a promotion, sales adjusts prices in SAP Business One. The shop displays the new conditions immediately, without anyone having to work in the backend.
Customer service with complete visibility. Service representatives see order history, open items, and delivery status in SAP Business One. They can answer customer questions faster and with more depth.

Service Layer as interface. MARINI uses the SAP Business One Service Layer (REST/OData) for the integration. The Service Layer must be installed and configured. Without an activated Service Layer, integration is not possible.
Bidirectional synchronization. Shopware 6 offers a modern Admin API and Store API. MARINI synchronizes products, customers, orders, and inventory levels in both directions. Webhooks enable event-based real-time synchronization.
Mapping and field rules. Shopware and SAP Business One have different data models. MARINI maps fields, validates content, and applies rules. Custom fields and user-defined fields (UDFs) are supported.
On-premises connectivity. SAP Business One is often operated on-premises or hybrid. MARINI can also connect on-prem systems without requiring installations in the ERP. This works securely via encrypted connections.
Business-critical data deserves maximum reliability. At MARINI, security isn’t an add-on—it’s our lived standard. Our security architecture at a glance:
This keeps your central data infrastructure stable, protected, and scalable at all times. Together, we’ll find the right integration and tailor it precisely to your requirements.
Typically products, categories, customers, orders, prices, inventory, and carts. Custom objects and user-defined fields (UDFs) from SAP Business One are also supported. Synchronization is bidirectional.

Yes. SAP Business One is often operated on-premises. MARINI can also connect on-prem systems without requiring installations in the ERP system. The connection is encrypted and secure.
