Teamwork | All Paychex Customers
Teamwork automatically targets the pay period Paychex currently has open for entry. It doesn't let you choose which period — it sends to whatever Paychex reports as active. Once that period closes, Teamwork can't submit into it and returns "No unused pay period found." There's nothing to fix at that point — the period is gone and the account must manually enter the pay data batch.
Submit Before the Processing Date, Not Payday
The period is typically already closed for entry by the check date, so do not use payday as your deadline anchor. Use the Processing Date in Paychex Flex — that's the real cutoff. To find it:
In Paychex: Log in and go to the Payroll Center or Payroll Overview dashboard.
Select the upcoming pay period — the Processing Date shown is your submit-by date.
Alternatively, check the Calendar/Schedule tab to see all upcoming payroll deadlines at once.
Two Things to Watch
Late submission: If a customer receives the error "No unused pay period found," the period has closed. The fix is forward-looking: submit the current open period on time. Past periods cannot be reopened from Teamwork.
Period transition zone: In the first days of a new period, both the old and new period can briefly appear active. If dates look incorrect, have the customer confirm that the period shown in Teamwork ("Open Payroll Start / End") matches what they intend to pay before submitting.
Payroll date sync: From the Teamwork payroll reports tab, the dates will match the open cycle in Paychex, but the data still will not send if past the Submit by date
What to Tell Customers
"When you submit payroll to Paychex, make sure it's before the Processing Date shown in Paychex Flex — not payday. Once the period closes, Teamwork won't show an error, so it can look like the submission went through when it actually didn't. If you are not seeing your employees hours and tips in Paychex pay data grid, check that the period was still open when you submitted. Going forward, use the Processing Date as your deadline."
