Connect weclapp with CRM, shop, and marketing: synchronize customers, articles, orders in real time. Bidirectional, GDPR-compliant, without installation.

Would you like to have consistent and accurate customer data in weclapp and Evalanche at all times without any IT projects? That’s exactly what MARINI is for.
With MARINI, the integration of weclapp and Evalanche is ready to use in just a few days and grows flexibly with your requirements.
And the best part: we handle the integration for you. Our experts set up your weclapp Evalanche 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 Evalanche and many other systems is also possible.






















weclapp is the cloud ERP for small and medium-sized businesses that combines inventory management, CRM, order management, and accounting on a single platform. Evalanche is the German marketing automation platform focused on B2B, lead management, and GDPR-compliant campaigns. Both systems are popular with growing companies looking to professionalize sales and marketing.
The weclapp Evalanche integration connects inventory management with marketing automation. Customer data, purchase history, and orders from weclapp automatically flow to Evalanche, while lead scores and campaign activities flow back to the ERP. This creates a consistent view: Marketing sees who’s already a customer, sales recognizes who’s currently active, and you can target existing customers with upselling or retention campaigns.
Sales and marketing often work with different data states. The integration ensures both teams access the same information and run relevant campaigns based on real transaction data.
Synchronize customers and contacts. Customer master data (Customers, Contacts) from weclapp is transferred as profiles to Evalanche. Pool memberships and custom attributes can be set automatically. Marketing always has current contact data for segmentation and campaigns.
Customer marketing based on purchase history. Who bought what and when? Which products does a customer already use? This data from weclapp flows to Evalanche and enables personalized cross-selling and upselling campaigns. Instead of generic newsletters, you send relevant offers based on real transactions.
Lead scoring back to ERP. Evalanche evaluates engagement: Who opens emails, clicks links, downloads whitepapers? This score is written back to weclapp. Sales sees directly in the ERP which contacts are currently active and can follow up with priority.
Trigger event-based marketing automations. Order completed, contract renewed, invoice overdue: Such events from weclapp automatically start workflows in Evalanche. Onboarding campaigns for new customers, reminders for open items, or feedback requests after delivery run without manual effort.
Send transactional emails with tracking. Order confirmations, shipping information, or invoices can be sent via Evalanche. You maintain consistent branding, track opens and clicks, and can directly integrate cross-selling elements in the emails.
Account Based Marketing with Custom Objects. Evalanche natively only offers profile-centric data. With MARINI Custom Objects, you can create a separate account entity: Account data from weclapp (revenue, industry, contract status) is stored in MARINI and linked to Evalanche profiles. Profile scores can be aggregated at account level. This enables true Account Based Marketing, even though Evalanche doesn’t support it natively.
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.

Marketing finally proves ROI. When campaign data from Evalanche is linked with revenue from weclapp, you see exactly which marketing activities lead to closures. No more gut-feeling budgets, but data-driven decisions. You invest in channels that actually convert.
Existing customers become a growth source. New customers are expensive. The integration enables targeted upselling and cross-selling with existing customers. Marketing automatically recognizes who uses which products and plays out matching offers. This increases customer lifetime value without doubling the acquisition budget.
Faster scaling without overhead. As your company grows, processes must grow too. With the integration, communication between ERP and marketing automation runs automatically. No manual copying of lists, no Excel acrobatics. Your team can focus on strategic tasks instead of data juggling.
For: Marketing, Sales, Customer Success, Operations
Segmentation becomes concrete. Previously, you may have segmented by industry or company size. Now you can segment by actual purchase data: Customers who bought product X but not Y. Customers with revenue over 50,000 euros last year. Customers with overdue invoices. Your campaigns become more relevant, response rates increase.
Sales knows who to call. Evalanche scores flow back to weclapp. If a contact has opened five emails in the last three days and downloaded a whitepaper, sales sees this directly in the ERP. No separate tool, no separate view. The next call comes at exactly the right time.
Customer campaigns run automatically. New customer registered? Onboarding series starts. Contract expires in 60 days? Renewal campaign starts. Customer hasn’t bought anything in six months? Re-engagement campaign starts. You build the workflows once, then they run without your intervention.
Consent management stays clean. Evalanche is GDPR-compliant and hosts in Germany. Opt-in and opt-out status is synchronized bidirectionally. If someone unsubscribes in the ERP, it’s updated in Evalanche and vice versa. You stay compliant without double maintenance.

Both systems have modern APIs. weclapp offers a REST API for all business objects (Customers, Articles, Sales Orders, Invoices, Inventory). Evalanche also has a REST API plus webhooks for event-based synchronization. MARINI connects both systems without requiring installation in weclapp or Evalanche.
Flexible mapping, individual field rules. Customer master data from weclapp is mapped to Evalanche profiles. You decide which fields are synchronized and which custom attributes are set in Evalanche. Calculated fields are also possible: Revenue buckets, product categories, or customer segments can be derived from weclapp data and written as tags in Evalanche.
Pool management and multi-tenancy. MARINI can synchronize multiple Evalanche pools simultaneously. In multi-tenant setups, pool aliases are correctly considered. If you manage different brands or business units in separate pools, data separation is maintained.
Custom Objects for Account Based Marketing. Evalanche doesn’t natively offer custom objects and follows a profile-centric approach. MARINI enables you to create custom objects in MARINI that serve as separate account entities. Account data from weclapp (revenue, industry, employee count) is stored in MARINI and linked to Evalanche profiles via API. Profile scores can be aggregated at account level to measure account engagement.
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 and Contacts from weclapp are transferred as profiles to Evalanche. Additionally, purchase history, orders, invoice status, and custom attributes can be synchronized. In the opposite direction, lead scores, campaign activities (opens, clicks), and consent status flow back to weclapp. Pool memberships and tags can be set automatically.
Evalanche natively only offers a profile-centric approach. True ABM becomes possible with MARINI Custom Objects: MARINI creates custom objects that serve as separate account entities. Account data from weclapp (revenue, industry, contract status) is stored in MARINI and linked to Evalanche profiles via API. Profile scores can be aggregated at account level to measure account engagement.
Both are possible. Evalanche supports webhooks that trigger synchronization immediately on events (new profile, changed score). weclapp changes can also be synchronized event-based. Alternatively, you can set up scheduled synchronizations, such as nightly updates for master data or hourly syncs for orders. MARINI offers flexible scheduling options.
Evalanche is a German provider with hosting in Germany and native GDPR features. Opt-in and opt-out status is synchronized bidirectionally: If someone unsubscribes in Evalanche, it’s updated in weclapp and vice versa. MARINI also hosts in the EU (ISO 27001 certified) and processes all data GDPR-compliant.
weclapp is typically leading for customer master data, orders, invoices, and inventory. Evalanche leads marketing activities, scoring, email engagement, and consent management. But you can also map hybrid scenarios: If marketing creates new contacts, they can be synchronized to weclapp. Leadership can be defined individually per object and field.
No. MARINI is neither a weclapp agency nor an Evalanche agency. Both adapters are ready to use out of the box, no installation in weclapp or Evalanche is required. MARINI offers full service: We can implement the integration completely for you or build it in a co-creation model with your team. You don’t need external system houses, configuration runs through MARINI’s no-code interface.
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.
