Beware, the payment can go through, in a day or two, the payment can be declined (basically an NSF). At that point you must manually create journal entries to reverse the transaction, recreate a new invoice to resend with a new payment link and then create a credit memo to clear out the first invoice linked to the declined payment. Someone should create a better process for this. If you have 2 or 3 declined payments in a month, it can get to be a hassle.
