PaySuite was discontinued by the end of the 2019/20 tax year. To run payroll for the new tax year 2020/2021, you'll need to upgrade to either our either QuickBooks Online Standard or Advanced Payroll depending on your payroll requirements. Check out this link for your guidance on how to upgrade: Migrating from PaySuite.
If you have not selected a date to upgrade or opted out of the upgrade, your payroll data will be moved to the payroll product (Standard or Advanced payroll) based on the features you use.
