# Billing Procedures

## Resolving Failed Payments

For self-service accounts on paid plans where a credit card on file is no longer valid, Mezmo follows this procedure.

1. Attempt billing. If failed, go to next step.
2. Wait 1 day. Retry billing. If failed, go to next step.
3. Wait 5 days. Retry billing. If failed, go to next step.
4. Wait 7 days. Retry billing. If failed, paywall is implemented on the account. Go to next step.
5. Wait until the end of the month. Retry billing. If failed, the account will be archived. Data ingested will no longer be saved.

> Enterprise accounts are not subject to automatic downgrades. If your Enterprise plan has a failed payment, contact your account representative or Mezmo support to resolve the issue.
