Connect and set up Paychex Flex

Connect Paychex Flex with Workstream to sync employee data seamlessly and simplify your onboarding to payroll process.

Connecting Paychex Flex with Workstream ensures a smooth data flow between your onboarding and payroll systems.

Once the integration is set up, new hire details collected during onboarding are sent from Workstream to Paychex Flex, keeping your payroll records accurate and up to date without manual effort.

šŸ“Œ You need the Edit onboarding processes and onboarding documents permission to set this up.

    Paychex Flex company ID

    If you have more than one Paychex company (for example, one per tax entity), add each one, then choose which company this onboarding process should use.

  4. Finish setting up the process and select Save.

If Paychex hasn't granted Workstream access yet, the company shows as Pending ("Pending Paychex approval (it can take 1 to 3 days)"). Workstream checks automatically and updates the status once access is granted.

šŸ’” If you don't see the Paychex task when building an onboarding process, contact Workstream Support.
