Connect SAP S/4HANA and CAS SmartWe: synchronize business partners, prices, orders bidirectionally. Real-time, without ERP installation. EU hosting.

Would you like to have consistent and accurate customer data in CAS SmartWe at all times without any IT projects? That’s exactly what MARINI is for.






















CAS SmartWe manages contacts and sales opportunities. The cloud CRM is affordable, quick to set up, and built for small teams. Yet even small teams need marketing leads in CRM, customer data in ERP, and engagement signals from marketing automation.
MARINI connects SmartWe with your ecosystem: contacts synchronized, leads automatically transferred, engagement data made visible. Bidirectional, real-time, no-code. Your sales team works with complete data, your marketing sees CRM status, your ERP knows every customer.
Small businesses choose affordable cloud CRM systems like SmartWe because cost per user is low and setup is quick. Yet precisely these companies often have a heterogeneous system landscape: marketing runs in Evalanche or HubSpot, accounting in weclapp or Dynamics 365 Business Central, the shop on Shopware. Without integration, SmartWe remains a data silo, marketing leads are transferred manually, revenue data is missing from CRM. MARINI connects SmartWe with all relevant systems and turns the affordable cloud CRM into the central data hub for sales and customer relationships.

CAS SmartWe integration is not an industry-specific topic — it is a process-driven one. That said, the concrete requirements vary considerably: in the financial sector, the focus is on compliance, KYC processes, and regulated data flows. In mechanical engineering and manufacturing, the priorities lie in partner sales, aftermarket processes, and complex customer structures with hierarchical relationships. In the media industry, it is subscriptions, reader engagement, and multi-channel distribution that drive integration needs. The following industry pages demonstrate how MARINI addresses these requirements in practice.
CAS SmartWe is an affordable cloud CRM for small teams. MARINI connects it with the rest of your system landscape, even when budgets are tight. Cloud connectivity, no installation, EU-only hosting.
Native connectors vs. integration platform. SmartWe offers individual native connections to selected systems, for example via webhook or API key. This works for simple point-to-point connections, but becomes complex as soon as you want to orchestrate multiple systems, transform data, or store centrally. MARINI delivers a central platform for all SmartWe integrations: bidirectional mapping, field rules, validation, duplicate management, monitoring, and logs in one place. You build the integration once and extend it as needed, without starting from scratch for each new system.
Custom development vs. permanent platform. Small companies occasionally develop their own scripts or Zapier flows to connect SmartWe with other systems. This works short-term, but becomes a maintenance nightmare as soon as APIs change or new requirements emerge. MARINI takes over technical maintenance: API updates, error handling, retry logic, and monitoring are included. You focus on your business processes, not script debugging.
Generic iPaaS vs. specialized solution. Platforms like Zapier or Make are generic and support many systems superficially. For complex B2B integrations, features like custom object mapping, relationship synchronization, or advanced duplicate management are often missing. MARINI specializes in B2B CRM integrations and knows the requirements of sales and marketing teams: hierarchies, activities, campaign attribution, and bidirectional synchronization without data loss.
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.
