# Rating and Billing

Rating and billing consists of loading usage records, calculating their charges and applying them to an invoice.

This is done through the following processes:

- Validing

**CDRs**

CDR = call detail record. This is a formatted string of information within a file that is supplied by a service provider. It contains the details of a call (such as service number, originating number, call start time, terminating number, etc.). Formats for CDR files vary by service provider.
- Applying charges to the CDRs
- Re-rating CDRs
- Creating call summary information
- Initiate billing (by calculating new invoice balances)
- Re-billing customers and/or billing groups for an invoice cycle
- Testing rate plan scenarios on line
