SAP C4C is a cloud-based CRM system for sales and service with native SAP integration. Dynamics 365 Finance & Operations is Microsoft’s enterprise ERP for finance, supply chain, and manufacturing with global scalability.
The SAP C4C Dynamics 365 Finance & Operations integration connects your CRM with your ERP. Sales works with current prices from the ERP, Finance sees at a glance which opportunities have been won, and customers experience seamless processes. No duplicate data entry, no media breaks, no more guesswork.
The connection synchronizes leads, accounts, opportunities, products, prices, sales orders, and invoices in real-time. This way you see who bought what when, and everyone works with the same data.
Leads from campaigns directly to sales. Marketing qualifies leads, sales takes them over in SAP C4C, and as soon as a deal is won, the data flows to Dynamics 365 F&O. No manual copy-paste, no lost contacts. Marketing and sales finally play on the same team.
Opportunities become sales orders. Won deals in C4C are automatically created as sales orders in F&O. Finance starts invoicing, operations prepares delivery. The entire quote-to-cash process runs through without anyone having to transfer data.
Products and prices always up-to-date. Your product catalog resides in Dynamics 365 F&O, including price lists, discounts, and availability. Sales sees this information in SAP C4C, creates quotes with correct prices, and doesn’t waste time with follow-up questions. No more false promises.
Create customers once, use everywhere. A new customer in Dynamics 365 F&O is automatically created as an account in SAP C4C. Sales, service, and finance work with the same customer view. No duplicates, no inconsistencies, no confused customers.
Invoice status visible in CRM. Finance creates invoices in F&O, the status flows back to C4C. Sales sees whether an invoice has been paid and can react proactively if payments are outstanding. Service can prioritize inquiries better. Everyone is in the know.
Synchronize custom objects. You use custom modules in SAP C4C or custom entities in Dynamics 365 F&O? No problem. MARINI synchronizes these objects as well, including field rules, validations, and mapping. Your individual processes remain individual.
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.

For: C-Level, Management, Business Development
Time is money, and you save both. Your team spends less time on data maintenance and more time with customers. The connection between SAP C4C and Dynamics 365 F&O eliminates manual processes, accelerates the order-to-cash cycle, and reduces error rates. That means: faster revenue realization, better forecasts, more satisfied employees.
One customer view for everyone. Sales, finance, and operations work with the same data at the same time. You make decisions based on complete information, not based on assumptions. Who pays on time? Who has potential for cross-selling? Who needs attention? You see it at a glance.
Scalability without headaches. New products, new markets, new business models? The connector solution grows with you. Fields, objects, and rules can be adapted without programming. Your IT roadmap remains flexible, your business agile.
For: Marketing, Sales, Customer Success, Operations
Sales works with real data. Your field sales team sees in SAP C4C which products are available, what they cost, and whether the customer has outstanding invoices. Quotes are accurate, deals faster, complaints rarer. Before: check three systems. After: everything at a glance.
Finance no longer waits for Excel lists. Won opportunities automatically become sales orders in Dynamics 365 F&O. Invoices are created without delay, incoming payments are immediately allocated. You close faster, your liquidity improves, your reporting is accurate.
Customer Success responds proactively. A customer calls, and you see immediately in C4C whether invoices are outstanding, which products they use, and how the last delivery went. You resolve inquiries faster, before small irritations become big problems. Before: jumping between systems. After: one view, all information.
Operations plans based on real pipeline data. You see in Dynamics 365 F&O which opportunities in SAP C4C are about to close, and can control inventory, production, or purchasing accordingly. No more surprises, no bottlenecks, no excess inventory.
For: IT, Development, System Architects, Admins
No more maintaining self-made scripts. You have better things to do than debug APIs or monitor CSV imports. MARINI handles authentication, mapping, error handling, and logging. You configure the connector solution via no-code interface, your developers can focus on strategic projects.
Bidirectional, real-time, conflict-free. SAP C4C uses OData REST APIs, Dynamics 365 F&O provides Data Entities. MARINI synchronizes in both directions, recognizes duplicates, and resolves conflicts according to defined rules. You determine which system is leading for which field. The connection runs stably, even when both systems make changes simultaneously.
Custom objects? No problem. You use custom modules in C4C or custom entities in F&O? MARINI maps these just like standard objects. You configure field rules, validations, and transformations yourself. No vendor lock-in risk, no compromises on your processes.
GDPR and revDSG compliant, EU-only hosting. All data remains in the EU, the data center is ISO 27001 certified. You meet compliance requirements without additional effort. Logs, monitoring, and alerts are included by default. You see at any time what has been synchronized and can intervene specifically in case of errors.
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, we synchronize accounts, contacts, leads, opportunities, products, prices, sales orders, invoices, and activities. Custom modules in C4C and custom entities in F&O can also be connected. You determine which fields, objects, and directions are relevant.
SAP C4C provides OData REST APIs for all standard and custom objects, Dynamics 365 F&O uses Data Entities. MARINI connects directly to these APIs, without detour via SAP CPI or other middleware. Authentication is done via OAuth 2.0. Synchronization runs bidirectionally and in real-time.
Yes. Dynamics 365 F&O is frequently operated on-premises or in private cloud. MARINI can also connect on-prem systems. You install a connector locally, the rest runs via the MARINI platform. Security and compliance remain guaranteed.
You determine which system is leading for which field. MARINI recognizes conflicts, logs them, and resolves them according to your rules. Example: Customer names are overwritten from F&O, opportunities from C4C. You keep control, the connection does the work.
This depends on the number of objects, the complexity of the mapping, and your custom requirements. Simple setups run in a few days, more complex projects need a few weeks. MARINI offers full service or co-creation, you decide.
The costs depend on data volume, number of objects, and desired service level. MARINI offers transparent pricing models without hidden costs. Contact us for an individual quote that fits your needs.
