weclapp is a cloud ERP with integrated CRM, inventory management, and accounting for growing companies. Leadtributor automates lead distribution to sales partners, dealers, and field sales with feedback tracking and escalation management.
The weclapp Leadtributor Integration connects ERP-based order processing with intelligent lead routing for partner sales. Leads from weclapp are automatically assigned to the right sales partner, while partner feedback and conversion data flow back into the ERP. This creates a seamless lead-to-order process across multiple sales levels.
You sell through partners, dealers, or field sales and want to know what happens to your leads.
Automatically route leads from weclapp. Customer inquiries from the weclapp CRM are synchronized to Leadtributor in real-time and assigned to the appropriate partner based on region, radius, or competencies. No more manual forwarding.
Partner feedback back to the ERP. Status updates, responses, and conversion data from Leadtributor automatically flow back into the weclapp customer record. Inside sales and management can see which partner is processing what.
From lead to invoice without media disruption. When a partner converts a lead into an order, it is seamlessly created in weclapp as a sales order. Order processing runs as usual, including warehouse management, delivery note, and invoice.
Escalation for non-processing. If a partner doesn’t respond within the defined time, Leadtributor automatically routes the lead further. The escalation history is documented in weclapp.
KPIs and reporting across both systems. Conversion rates, average processing time, and partner performance from Leadtributor are combined with sales data from weclapp. This shows you which partners actually generate revenue.
Keep customer database synchronized. New customers acquired through partner sales are automatically created in weclapp, including partner assignment and complete lead history.
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.

Data exchange from Leadtributor to other systems such as CRM, ERP, or marketing automation is a prerequisite for our success. With MARINI, many systems can be connected to Leadtributor with ease. This way, our customers have no overhead and all data (leads, contacts, etc.) remains synchronized across all their systems at all times.
For: C-Level, Executive Management, Business Development
50% of deals go to the vendor who responds first. With the integration, you ensure that no lead disappears into the black box of partner sales. Automatic routing and escalation management guarantee fast response times, which directly impacts close rates.
Manage partner performance based on real numbers. You see not only who processes how many leads, but also who actually generates revenue. The connection between Leadtributor KPIs and weclapp invoice data gives you a fact-based foundation for partner discussions and territory decisions.
Scaling without losing control. The more partners you bring on board, the more complex lead distribution becomes. The integration automates the entire routing process while you maintain oversight via the weclapp dashboard. This allows you to expand your partner network without building additional capacity in inside sales.
For: Marketing, Sales, Customer Success, Operations
Before: Leads distributed to partners via Excel lists, no feedback. You manually matched postal codes, sent emails to partners, and then waited. Following up had to be done manually. Now: Lead comes into weclapp, Leadtributor routes automatically, partner provides feedback with one click, status appears immediately in the ERP.
Map sales territories digitally instead of in people’s heads. Who is responsible for which region? Which partner has which product competency? This is now stored in Leadtributor and applied automatically. No more discussions, no duplicate processing, no partner feeling overlooked.
Partners only see what they should see. External sales partners don’t need access to your weclapp system. They receive their leads via email or app, provide feedback, and you see everything centrally in the ERP. You retain control of your customer data.
Track campaign success down to partner conversion. Marketing generates leads through events, webinars, paid ads. These land in weclapp, are routed to Leadtributor, and you can see which campaign led to which revenue through which partner. Finally, the complete funnel, even for indirect sales.

Connect weclapp REST API v2 with Leadtributor Open API. Both systems offer modern REST endpoints. MARINI synchronizes the relevant objects: Customers and Contacts from weclapp, Leads and Partner Feedback from Leadtributor. The connection is bidirectional via the MARINI HubEngine.
Correctly map the Party endpoint in weclapp v2. In weclapp API v2, Customers, Contacts, Leads, and Suppliers run through the central Party endpoint. MARINI correctly maps Leadtributor leads to the corresponding Party objects and sets the right flags for lead qualification and partner assignment.
Event-based synchronization via webhooks. Both weclapp and Leadtributor support webhooks. New leads, status changes, and feedback updates automatically trigger synchronization. No polling, no delay, no unnecessary API traffic.
Custom attributes and flexible mappings. Leadtributor works with competencies, attributes, and individual fields. weclapp allows custom attributes on all objects. MARINI maps the specific requirements of your lead distribution without hitting system limitations.
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 synchronized as Leads to Leadtributor. In the opposite direction, lead status, partner assignment, feedback, and conversion data flow back. Optionally, Sales Orders from successfully converted leads can also be automatically created in weclapp. Custom attributes in both systems are supported.
This depends on your process. Often weclapp is leading for customer database, orders, and invoices, while Leadtributor controls lead routing and partner management. The integration is bidirectional: lead generation usually starts in weclapp or an upstream marketing system, while partner feedback and conversion status come back from Leadtributor. MARINI seamlessly maps both directions.
Leads from weclapp are synchronized to Leadtributor. There, routing takes place based on postal code, radius, competencies, or other criteria. The assigned partner receives a notification via email or app. If they don’t respond within the defined time, Leadtributor automatically escalates to the next partner. The entire history is written back to weclapp.
No. Partners work exclusively in Leadtributor, either through the web interface, mobile app, or directly via email link. They provide feedback with one click, without having to log into an external system. All information you need as a manufacturer flows automatically back into the weclapp system. Your customer data remains under your control.
Yes. If leads come from weclapp with campaign information, this data is preserved throughout the entire process. Leadtributor tracks which partner processed the lead, weclapp shows the resulting order and revenue. This allows you to perform ROI calculations not just to the lead, but to the actual closing through partners.
The technical integration via MARINI is ready to use in a few days. Both systems offer modern APIs, no installation is required. The greater effort usually lies in process definition: Which partners get which leads? What are the escalation rules? Which data should flow back? MARINI supports you with the design or takes over the complete implementation in full-service mode.
With MARINI, we use a reliable interface between our existing ERP system and HubSpot. The data exchange works seamlessly and delivers tangible added value in our day-to-day operations. We are particularly impressed by the platform’s clear structure as well as the direct and straightforward communication with the support team.
