For customer care it is extremely useful when a customer has had one or more failed payments to be able to share a link with that customer so he or she can pay the invoice directly!
In Firmhouse, you'll find an invoice section on the subscription detail page where you will find a button for failed payments labeled 'Show invoice payment link'.
What this does is open a modal and shows you an URL that can be shared with the customer.
If the customer opens that unique URL for the invoice they are able to make a single payment that is outside of their regular subscription payments. Depending on the enabled payment method(s) the user is able to select, for example, a different bank or payment method for this specific payment.
