If you want to restrict clients to only adding their bank account as a payment method (meaning that they can only pay with ACH) you should use this function.
With this option checked, new clients will only be able to pay using ACH. Existing clients will be able to use their existing card on file until it expires at which point their only option will be to add a bank account.
How do I set Adding a Bank Account as my only Payment Method?
Check the boxes for "Prefer ACH" and "Do not allow new cards".
Clients are now asked to add a bank account in preference to another payment method. Although your clients still have the choice to click the link to add a card if they prefer.
