Beforehand, the "External" payment method was more of a catch-all payment method for anything sold where payment was processed outside of the system. Now, you can classify box office transactions as paid via ACH or Check explicitly.
In the Box Office app, agents add items to a cart as they normally would, and when they get to payment, choose the External tab. They'll see the ability to choose ACH or Check alongside External Device.

They can use all payment methods for known-customer sales or anonymous customer purchases.
Tip: use order notes after the fact to notate the check # of ACH reference #.
Reports have been updated to itemize and filter by these additional payment types.

This is only available in the Beta Box Office--the future of Box Officing.
