It's easy — you need to enrol in the Salary user program on the Fi app.
To do this:
Tap 'Upgrade to Salary Account' on the Home screen.
Next, contact your HR/ Payroll team to upgrade this Savings Account to your Salary account, as Fi only enables this program to its partner companies.
After your salary is credited for the first time in this Savings Account, you will automatically receive the Salary plan upgrade and all of its benefits!
