SAP payroll is at a generational crossroads: thousands of organisations still run on-premise SAP Payroll (a deeply proven engine), SAP's strategic direction is SuccessFactors Employee Central Payroll, and a mature managed-payroll market happily runs the whole function as a service. The decision is as much operating-model as software: who owns payroll expertise, per country?
The providers below focus on the service-and-platform side — global payroll platforms and EOR-capable providers with SAP integration. All post payroll results into SAP GL; they differ in country breadth, managed-service depth and how natively they consume SAP (or SuccessFactors) HR data.
