And the best part: we handle the integration for you. Our experts set up your weclapp Magento interface on your behalf or together with your team.
Important note: The video shows the integration of HubSpot with SAP C4C. Of course, connecting to weclapp with Magento and many other systems is also possible.






















weclapp is a cloud-based ERP with integrated CRM, inventory management, and accounting for small and medium-sized businesses. Magento (or Adobe Commerce) is one of the most powerful e-commerce platforms for sophisticated online shops with extensive product catalogs and complex requirements.
The weclapp Magento integration connects both systems bidirectionally in real-time. Orders from the shop automatically become orders in weclapp, inventory levels and prices flow back to the shop. The result: no duplicate data entry, no system breaks, no overselling. Your teams work with current data, customers see accurate delivery times.
Without integration, every order leads to manual transfer, inventory levels are juggled via Excel, price changes get lost. The consequence: errors, delays, frustrated customers and teams.
Automatically transfer shop orders to the ERP. As soon as a customer orders in the Magento shop, the order is created in weclapp. Customer data, items, quantities, prices, and shipping addresses are transferred error-free. Your team can pick, pack, and ship immediately.
Synchronize inventory levels in real-time. Availability from weclapp is displayed in the shop. Customers see whether an item is in stock, ships today, or arrives in two weeks. Overselling is a thing of the past.
Manage prices centrally and use them everywhere. You change prices in weclapp, they appear in the shop. Discount campaigns, tiered prices, and customer group conditions are transferred automatically. No second price system, no discrepancies.
Sync customer master data between shop and ERP. New customers from the shop are created in weclapp, master data remains synchronized. You have a consistent customer view for sales, service, and accounting.
Manage product data centrally. Item master data, descriptions, attributes, and categories are transferred from weclapp to Magento. You maintain once, publish everywhere.
Display delivery status and tracking in the shop. As soon as picking or shipping occurs in weclapp, the customer receives an email with tracking information. Fewer inquiries, better customer experience.
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.

With MARINI, we have found a flexible and reliable partner for data integration with our customers. In today’s environment, we’re dealing with countless systems. At the same time, resources, especially in IT, are becoming increasingly scarce. Through MARINI, we conveniently deliver our data to any of our customers’ systems, whether CRM, ERP, or MDM – quickly and securely.
For: C-level, Management, Business Development
Scaling without chaos. When your shop grows, orders and complexity grow too. With automated synchronization, processes remain stable, even with 500 orders per day. You can enter new markets without doubling your team.
Liquidity through faster processing. Every minute an order ships earlier brings you closer to payment. Automation shortens order-to-cash time, improves cash flow, and reduces capital tied up in inventory.
Data-driven decisions instead of gut feeling. When shop and ERP data are synchronized, you see in real-time which products are performing, where bottlenecks emerge, and which customer groups are most profitable. You can react faster and plan more strategically.
For: Marketing, Sales, Customer Success, Operations
Personalization based on real purchase data. When order history and product interests flow from Magento to weclapp (and further to CRM), you can segment campaigns based on actual buying behavior. Cross-selling and upselling become relevant instead of annoying.
No guesswork with customer inquiries. A customer calls asking about their order. Your service team sees the order status, shipping information, and payment receipt in weclapp immediately. No follow-up questions, no waiting time, satisfied customers.
Fewer returns through accurate delivery promises. When the shop displays real inventory levels, customers only order what’s available. You avoid cancellations, frustration, and negative reviews.
Targeted reactivation of cart abandoners. Abandoned carts from Magento can flow to CRM via weclapp and trigger nurturing workflows. You bring back potential buyers before they go to the competition.
For: IT, Development, System Architects, Admins
APIs instead of plugins. MARINI uses the REST APIs of weclapp and Magento 2. No installation in the shop, no plugins that break with every update. You retain control over your systems and can upgrade anytime.
Bidirectional synchronization with conflict resolution. Data flows in both directions. You define which system is authoritative for which entity. MARINI handles mapping, validation, and resolves duplicates. In case of conflicts, you decide how to react.
Custom attributes and multi-store scenarios. Magento allows custom attributes on products, customers, and orders. MARINI synchronizes these fields too. If you operate multiple Magento stores, all can be connected to the same weclapp instance.
Monitoring, logs, and alerts in real-time. Every synchronization is logged. You see in a dashboard which data was transferred when and whether errors occurred. Alerts via email or Slack keep you informed.
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, customers, orders, products, inventory, prices, categories, and delivery status are synchronized. Invoices, delivery notes, and tracking information from weclapp flow back to the shop. Custom attributes from Magento are also supported. You decide which objects and fields are synchronized.
Yes, MARINI can integrate both Magento 1 and Magento 2. Magento 1 reached end of life in June 2020 but is still used by many shops. Magento 2 offers more comprehensive APIs (REST, GraphQL) and is the recommended version. Both can be integrated with weclapp.
It depends on the data type. Inventory levels, prices, and orders typically come from weclapp. Product presentation in the shop, categories, and customer preferences are often maintained in Magento. MARINI allows you to define which system is authoritative for each entity. Bidirectional synchronization is possible.
Yes. If you operate multiple Magento stores or websites, all can be connected to the same weclapp instance. MARINI orchestrates the data flows and can apply store-specific rules. This is especially relevant for international setups or different brands.
No. MARINI uses the native REST APIs of weclapp and Magento 2. Nothing needs to be installed in your systems. This means: no dependencies on plugin updates, no compatibility issues with system upgrades. You retain full control.
MARINI synchronizes in real-time. As soon as an order comes in Magento, it’s created in weclapp. Changes to inventory levels or prices in weclapp appear in the shop within seconds. You can configure sync intervals and triggers as needed.
Data is only the gold of the digital age when it is integrated and consistently translated into decisions. That is exactly what MARINI stands for: we connect data sources, make data actionable, and enable purpose-driven, model-based analytics—fully aligned with the principles of Robotic Selling.

With MARNI, we were able to successfully optimize our digital sales processes. We were particularly impressed by the flexibility and scalability of the platform, which helped us to implement our projects quickly and efficiently.
