Some more context from review:

Probably not; we need to be really careful not to give the impression that the payent has failed, when actually only sending the receipt has.

Potentially this would be a good place for the view to handle the thrown errors somehow; then we can more easily display the error in-line with the receipt call that they relate to. This would probably need a specific view that can handle them, rather than the default button.

In the IPP version of this, the button turns into a spinner while it's sending, then a check mark when it's done. Equally, it could show the error and a retry button if it fails.
