# Recover unpaid invoices

> Use the Korint app to track and retry failed payments.

With a large number of policies all being billed at different rates, it is easy to lose track of
outstanding invoices. Korint proposes an unpaid management module to visualize failed payments,
and automate payment recovery.

## Customer Balance

Each customer has a balance tracking the difference between invoices and payments. If a balance is negative,
then the customer owes money for their policy. If the balance is positive, then the customer is owed money - typically
this happens after a customer requests to stop the policy at a date far in the past, for example if they forgot to
declare a sale of their insured asset.

## Tracking failed payments

Each brokerage firm can access an accounting summary of their portfolio. In it you will find a list of all policies that have at least
one failed payment, with information such as:

* the policy
* the number of unpaid invoices for that policy
* the number of days since the failed payment
* links to dashboards so that you can retry payment, send a recommended letter (ERE) if configured, suspend or stop the policy.

You can filter these results by issuance date of the invoices.

All failed payments can be retried. By default, the retry will use the current default payment method.

## Charging additional fees

At a product level you can configure additional fees for unpaid invoices. If a payment fails for an invoice, the additional fees
will be added to a replacement invoice, and a new payment will be attempted.

For example, a customer is invoiced 100€, and additional fees are set to 10€. If the payment for that invoice fails, then the invoice
is automatically credited and a new invoice for 110€ is issued.

| Invoice          | Amount | Status                                            |
| ---------------- | ------ | ------------------------------------------------- |
| Original invoice | 100€   | WRITTEN\_OFF - This invoice has been credited     |
| Credit invoice   | -100€  | CREDITED - Credits Original invoice               |
| December 2025    | 110€   | PAYMENT\_IN\_PROGRESS - Replaces Original invoice |
