Data Integration between Salesforce and ERP Systems: A Middleware-Based Approach

Abstract

Effective data synchronization between Salesforce Customer Relationship Management (CRM) and Enterprise Resource Planning (ERP) systems remains a critical challenge in multi-platform enterprise environments. Discrepancies between customer, inventory, and order data can create operational inefficiencies and erode customer satisfaction. This study proposes a middleware-based integration framework utilizing MuleSoft and custom RESTful APIs to enable both batch and real- time bi-directional synchronization between Salesforce and SAP ERP. The architecture addresses typical challenges such as data latency, transformation inconsistencies, and fault tolerance. A case study was conducted in a retail organization integrating Salesforce Sales Cloud with SAP S/4HANA. By combining platform events, Apex triggers, and MuleSoft’s Anypoint Platform, the system achieved latency below 3 seconds for critical transactions, with over 98.5% data consistency in asynchronous flows. This paper evaluates architectural patterns, performance benchmarks, and governance strategies employed. The findings support middleware as a viable solution for unifying enterprise application ecosystems in real-time.
