Hi janeflorist,
On your current subscription, you can only process payroll for up to 4 employees per month. For example, if you have already processed payroll for 4 employees prior to the current pay run, and now you are trying to process payroll for another 3 different employees, the system will count these additional employees as the 5th, 6th, and 7th employees. This is why you are seeing the warning message. To avoid this, you would need to either stay within the 4-employee limit or consider upgrading your subscription to accommodate more employees.
Regards,
Sai
