If you email an invoice to your customer with a credit card payment link with Stripe, and now want to manually enter a payment on the invoice or need to edit the invoice, first you will need to disable the credit card payment link.
This prevents an accidental double or incorrect payment on the invoice, and the customer will not be able to pay with a credit card.
You can find the Invalidate Payment link on the Apply Invoice Payment screen. Click "Invalidate Payment Link" if you want to manually enter a payment here.
If you invalidate the payment link, this is what your end customer sees when they click "Click here to pay by credit card" in their invoice email.
Note: You can only invalidate the payment link for one invoice at a time. If it's a recurring invoice, the payment link will reappear for following invoices.
If you accidentally invalidate the link and you want to continue allowing the end customer to pay this invoice by credit card, you will need to email the invoice again, and make sure the invoice is still set to accept a credit card payment.
