Personio to ADP Integration: How to Connect Personio with ADP iHCM

When a hiring manager presses the hired button in Personio, the new employee’s information appears in ADP iHCM automatically — nobody retypes it. Flexspring connects Personio to ADP directly, so new hires, employee updates, and bank details move across in near real time. Your team gets fewer payroll corrections, faster onboarding, and an end to double-data entry between HR and payroll.

Flexspring builds, hosts, and monitors the connection for you. There are no files to upload and nothing for your team to maintain. A turnkey integration goes live in 2–4 weeks and a custom integration in 10–12 weeks. With Flexspring, you only pay for the use case or use cases you need.

How the integration works

1
Scoping. You pick the use cases you need from the list above. Flexspring maps every field between the two systems, including your custom fields and business rules.
2
Direct connection. Flexspring iPaaS connects the two systems to each other over secure APIs. There are no spreadsheets to export, no files to transfer, and no manual steps in the middle.
3
Near real-time sync. When a record changes — a hire, a promotion, an approved time-off request — the change moves across in near real time rather than waiting for an overnight batch.
4
Monitoring and error handling. The integration is monitored continuously, with error handling, visibility into every transaction, and a named support contact. When either app changes their API, Flexspring updates your integration.
5
Ongoing changes. Your integration is future-proofed for ongoing enhancements without re-implementation, and adapts to custom fields, new locations, new systems and business rules.

Flexspring iPaaS does not store employee data beyond temporary transaction logs, and meets SOC 2, GDPR and ISO 27001 standards.
