Introduction

In today’s connected business environment, enterprises rarely operate with a single application. Sales, finance, customer service, and expense management often run on separate platforms — each excellent at what it does, but potentially creating operational silos when they don’t communicate effectively. For companies using SAP S/4HANA Public Cloud, this is especially true when integrating with Salesforce for CRM, SAP Concur for expense management, or other specialized applications. Without seamless connectivity, the result is slow data flow, duplicated effort, and incomplete visibility.

The Business Challenge

One of our professional services clients operated with:
• Salesforce for managing customer relationships and contracts
• SAP Concur for tracking and approving expenses
• SAP S/4HANA Public Cloud for finance, billing, and project accounting

The absence of robust integration led to:
• Manual re-entry of Salesforce contract data into S/4HANA for invoicing
• Delays in expense posting from Concur to S/4HANA Accounts Payable
• Data mismatches between systems, causing reconciliation and reporting delays
• Increased administrative workload across finance and operations teams
