Flexspring Named HR Data Integration Experts of the Year

Workday to Paychex Flex Integration: How to Connect Workday with Paychex Flex

When someone is hired in Workday, their information appears in Paychex Flex automatically — nobody retypes it. Flexspring connects Workday to Paychex Flex directly, so new hires and later changes to an employee record reach payroll with the information needed to pay people correctly. Your team gets fewer payroll corrections and an end to double-data entry between HR and payroll.

Flexspring builds, hosts, and monitors the connection for you, and no internal IT resources are needed — Flexspring’s experts do all the custom data mapping. A custom integration is fully deployed in 8-10 weeks.

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.

Do you actually have to choose?

A lot of people arrive here comparing the two products. If you’re deciding which single system to buy, that’s a real decision and this guide won’t make it for you.

But many teams don’t choose. They keep Workday as the HR system of record — where managers hire, update records and run reporting — and Paychex Flex for payroll. That works well, right up until someone has to keep both in sync by hand. Disconnected apps are the problem this data integration solves: Workday stays the place people work, and Paychex Flex gets clean data on time without anyone retyping it.
