Need a pattern to choose 1 or both of 2 options (+ edited for clarity)

I have a screen which allows the user to capture bank account information (+ the account information is for someone that the user wishes to pay, either now or later - this is a banking context, not e-commerce) and then choose what to do with that information. The options are either pay or save or both. (+ the user may not be paying at this point so a solution that requires immediate payment will not work)

In my prototype (used for concept testing) I have represented these as 2 checkboxes. The user must select 1 or both. The interaction is clumsy and I'm looking for a more elegant solution.

The immediate requirement is for Web (desktop and mobile) but there may be a requirement for native app as well.

Any suggestions would be appreciated.
