When setting up Zenefits Payroll, you'll be given an effective date or start date. This will be the first date that you can approve a pay run in Zenefits. Note that you can create pay runs prior to this date, but you won't be given the option to approve them until the effective date.
The effective date that you choose will be the first day you are charged for Zenefits Payroll. While you will be billed for your base package starting the day you sign up for Zenefits, the charges specific to Payroll will not begin until your effective date.
If you forget your payroll effective date, or you have any questions or concerns, please feel free to reach out to the salesperson who assisted you, your CSM, or Zenefits Support.
