Disabling a payment link in an invoice
I sent a customer an invoice with an early renewal discount but he didn't pay within the required timeframe. Based on his payment history, I suspect he will eventually pay but I don't want him to have that discount anymore. How do I keep him from just clicking the payment link in the original invoice and paying the discounted amount? Is there a way to disable the payment link in the original invoice so that he has to request a new invoice?
