Important note: The video shows the integration of HubSpot with SAP C4C. Of course, connecting to weclapp with Dynamics 365 Sales and many other systems is also possible.






















weclapp is a cloud-based ERP system for small and medium-sized businesses with integrated inventory management, CRM, e-commerce connectivity, and accounting. Dynamics 365 Sales is Microsoft’s CRM platform for sales with AI-powered insights and native Microsoft 365 integration.
The weclapp Dynamics 365 Sales integration connects sales activities with operational order processing in real time. Customers, contacts, opportunities, products, and orders flow bidirectionally. Sales teams work with current prices and inventory levels, while order fulfillment and accounting experience no delays.
The integration eliminates the typical gap between sales system and ERP.
Synchronize customer data end-to-end. Accounts and Contacts from Dynamics 365 Sales are created as Customers and Contacts in weclapp. Bidirectionally: changes in accounting or service immediately reach sales. No more duplicate data maintenance.
Turn opportunities into orders. As soon as a deal is marked as won in Dynamics 365, a Sales Order is automatically created in weclapp. Delivery dates, prices, and payment terms flow along. The sales process no longer ends in an Excel list.
Provide products and prices from the ERP. Articles and Price Lists from weclapp are available in Dynamics 365. Sales works with current conditions, not outdated calculations. Quotes are reliable.
Display invoice status in the CRM. Open items, payment receipts, and dunning status from weclapp appear directly in the Dynamics 365 Account. Sales can communicate proactively before problems escalate.
Manage quotes bidirectionally. Quotes from Dynamics 365 are saved as Quotations in weclapp. Changes by the inside sales team flow back to the CRM. Both teams work on the same document.
Make inventory visible to sales. Inventory from weclapp informs sales about availability. Delivery dates are based on real data, not guesswork. Customer satisfaction increases.
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.
