SAP to ADP Integration: How to Connect SAP with ADP

With data integration, new hires, employee changes, tax details and approved time off move from SAP to ADP automatically, and payroll journal entries flow back from ADP into SAP. Flexspring builds the integration to match your custom fields and business rules, then hosts and monitors it.

You decide which information you want to sync, and a data integration expert like Flexspring maps every field between the two systems and builds the connection. Custom integrations by Flexspring include unlimited custom fields and unlimited business rules. There is nothing for your team to install or maintain.

With data integration, new hires sync, including your custom fields, along with employee changes and rehires. You can also add approved paid time off, one-time payments such as bonuses and stock awards, direct deposit details, departments, locations, jobs and cost centers, interdepartmental transfers, benefits and allowances, time and attendance, and tax details and deductions. Payroll journal entries flow from ADP back into SAP.

Flexspring builds, hosts, and monitors the connector. An essential-fields build — standard fields plus up to five custom fields — goes live in 4–6 weeks. A custom build with more custom fields and business logic takes 8–10 weeks. The guide explains which one fits your setup. Custom integration by Flexspring includes unlimited custom fields and unlimited business rules. Flexspring does all the data mapping, so no internal IT resources are needed.

Flexspring does not store employee data beyond temporary transaction logs, and does not require anyone to handle the data manually. Flexspring meets SOC 2, GDPR and ISO 27001 standards.

No internal IT resources are needed to create your data integration. Flexspring’s team builds the integration to your requirements and monitors it afterwards, including handling API changes from either vendor. Your part is deciding which use cases you need and confirming Flexspring’s recommendations for how your fields should map.

With data integration, when a hiring manager presses the hire button in SAP, the new employee’s information appears in ADP automatically — nobody retypes it. Payroll journal entries flow the other way, from ADP into SAP, so your general ledger stays current without a manual export.

The best way to connect SAP to ADP depends on your data and business requirements. A standard connector can work for simple data flows, while custom fields and unique business rules require a tailored integration. If you go the custom route, you can build the integration yourself or choose a managed integration like Flexspring’s — built and maintained for you, which is typically faster and cheaper.
