Connect your ERP, CRM and inventory management systems to your online shop

There are four ways to connect an inventory management system. They differ in effort, costs, and maintainability – not in whether they work at all:

• Manufacturer's finished connector: JTL, plentymarkets, Xentral, and Actindo provide their own interfaces for common shop systems. This is the fastest way – but you'll be limited to the manufacturer's specific functionality.
• Direct API connection: REST or GraphQL on the shop side (Magento 2, Shopware 6, WooCommerce, Shopify), REST, SOAP or OData on the ERP side. The usual approach when custom fields or rules are involved.
• Middleware: This is useful when a system lacks a usable API or when multiple systems are interconnected. It translates formats and handles failures, preventing orders from being lost.
• File or database exchange: CSV and XML via SFTP or direct database access. For older inventory management systems, this is often the only way – and perfectly adequate if stock levels don't need to be accurate to the second.

The best approach depends on three questions: What interface does your inventory management system provide? How up-to-date do stock levels need to be – in real time or every 15 minutes? And in which direction does the data flow?

Typical scope of a connection: Articles, variants and attributes from the merchandise management system to the shop; orders and customer data back to the merchandise management system; stock levels and prices continuously synchronized; invoices, credit notes and tracking numbers back to the shop.

An ERP-shop integration connects your inventory management system (ERP/WMS) directly with your online shop (Magento, WooCommerce, or Shopware). This enables:

• Automated processes: Orders are automatically transferred to the ERP system.
• Real-time inventory: Stock levels are always up-to-date in the shop
• Time saving: No manual data maintenance across multiple systems
• Error reduction: Fewer errors through manual input
• Scalability: Growth without additional personnel costs

Studies show that companies with integrated systems can save up to 40% of their process costs.

We are integrating the three leading e-commerce platforms:

• Magento (Adobe Commerce): Version 2.3+ and Adobe Commerce Cloud
• WooCommerce: From version 5.0 onwards with WordPress 5.8+
• Shopware: Shopware 5 Professional and Shopware 6 (all editions)

These can be connected to over 30 different ERP, CRM and WMS systems, including SAP, Microsoft Dynamics, JTL-Wawi, plentymarkets and many more.

The integration time depends on complexity and scope:

We work agilely and deliver the first functional partial integrations after just 2 weeks.

Both occur – and the decision is based on the range of functions, not the purchase price.

Ready-made extensions are available for the most common combinations: JTL-Wawi with Magento 2 or WooCommerce, plentymarkets with Shopware, and Pickware within Shopware. They are quick to set up and inexpensive to purchase. Their limitations arise when dealing with custom fields, different pricing logics, B2B tiered pricing, or multiple warehouse locations.

A custom interface is worthwhile as soon as your processes deviate from the standard: customer-specific price lists, product configurators, multi-warehouse, multiple clients – or an inventory management system for which there is simply no ready-made connector.

In practice, the most common approach is a middle ground: using an existing extension as a foundation, supplemented with precisely the fields and rules that are missing from the standard. This is generally more cost-effective than developing a new extension from scratch and more flexible than relying solely on the standard. We can advise you on the best approach for your specific situation after reviewing your system's interface documentation.

By default, we synchronize the following data types:

Base data:

• Articles/products including variants and bundles
• Categories and product groups
• Customers and customer groups
• Suppliers and manufacturers
• Prices and tiered pricing

Movement data:

• Orders and contracts
• Invoices and credits
• Delivery notes and shipping data
• Returns and complaints
• Incoming payments

Inventory data:

• Real-time inventory levels
• Availability and delivery times
• Reservations and bookings
• Multi-warehouse management

Yes, we offer various synchronization options:

• Real-time: Instant transmission via webhooks and event triggers
• Near-real-time: Every 1-5 minutes via message queues (RabbitMQ, Redis)
• Interval sync: Hourly, daily or according to an individual schedule
• Batch processing: Nighttime large data transfers
• On Demand: Manual synchronization if required

We will choose the optimal method based on data volume, system load and your requirements.

We use modern API technologies for secure and high-performance integrations:

API types:

• REST APIs: For modern cloud systems (JSON-based)
• GraphQL: For flexible data queries (Magento 2, Shopware 6)
• SOAP/XML: For legacy systems and SAP
• OData: For Microsoft Dynamics and SAP
• Webhooks: For event-based real-time updates

Authentication:

• OAuth 2.0 for secure token-based authentication
• API keys with IP whitelisting
• JWT (JSON Web Tokens)
• Certificate-based authentication for enterprises

Safety is our top priority:

• Encryption: TLS 1.3 for all data transmissions
• GDPR compliance: Full compliance including data processing agreement (DPA).
• Audit logs: Complete logging of all transactions
• Backup & Recovery: Automatic data backup before each synchronization
• Monitoring: Monitoring: 24/7 monitoring with automatic alerts
• Penetration Testing: Regelmäßige Sicherheitsaudits
• Error handling: Automatic retry with exponential backoff

We support all current Magento versions:

• Magento Open Source: 2.3.x, 2.4.x (currently 2.4.7)

For Magento 1.x, we offer migration paths to Magento 2 with simultaneous ERP integration.

SAP Magento integration can be achieved in several ways:

• SAP Business One: Via DI API or Service Layer (OData)
• SAP S/4HANA: Via SAP Gateway and OData Services
• SAP ECC: Via RFC/BAPI or IDoc

Integration scope:

• Bidirectional product synchronization
