You may choose to link an account manually with an account number and routing number. This will require a one-time verification process to confirm the account is under your control. See more about verification of manual links here.
When an account is manually linked, Flourish Cash will not be able to display the balance of your linked account, and hence Flourish SmartBalance will not be available. However, you can still initiate transfers into and out of your accounts yourself at any time on the Transfers page.
Please note that beyond the above restrictions, your Flourish Cash account will function identically whether you manually link accounts or link accounts via secure online login.
