Firmhouse offers several ways for your customers to pay for an invoice manually. This is useful when a charge on someone’s credit card or bank account fails, or when you create an invoice manually for a customer to cover extra one-time costs like repairs or additional services. Every invoice generated by Firmhouse has its own unique link. On this link, the customer can view their invoice and its payment status. If the invoice is unpaid, they can pay for it straight from the invoice page with their preferred payment method.Documentation Index

Finding and Sharing Payment Links
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.

How Customers Access Invoice Payment Links
Customers can get invoice payment links in several ways:- You copy-paste the link from your customer’s detail page in the Firmhouse portal (as described above)
- From a link included in billing or failed payment email notifications
- From the Invoices overview in the Firmhouse Self Service Center
Invoice Payment Page
When a customer opens an invoice payment link, they see the invoice details and a payment button if the invoice is unpaid. They are able to make a single payment that is outside of their regular subscription payments, and depending on the enabled payment method(s), can select a different bank or payment method for this specific payment.
When Manual Payment is Available
Customers can manually pay their invoice even when automatic payment retries are scheduled for a future date. However, manual payment is temporarily blocked when a retry has already been initiated and is waiting for bank confirmation (for example, SEPA payments that take 1-2 days to process). Once the retry attempt completes (either successfully or by failing), manual payment becomes available again. If a customer pays manually while a retry is scheduled, the scheduled retry will be automatically cancelled to prevent duplicate charges.Saving the Payment Method for Future Use
Customers can save a new payment method on their subscription when they pay for an invoice via payment link. They can do this by leaving the “Store payment method for future payments” option checked.
