I have a “Print invoice” button in the payment screen. I need to make sure that the user printed an invoice before been able to click on the “Credit card” payment option.
I have tried validating using a “Payment processed” rule along with the “Cancel Ticket Payments” action in case an invoice was not printed for the ticked. Unfortunately the Cancel Payments action cancels “all” the payments.
I need to prevent the user from leaving the Payment screen an amount is been payed with a credit card and no invoice was issued. When I issue an invoice I create I ticket tag on which I can later look up for.
Is there an easy way to solve this problem?
