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.

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.

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.
