Frequency of closing the Billing period

The best business practice is to close the Billing period before you close the General Ledger period.

When you close the Billing period, the Billing application checks for records that were not updated to the general ledger, such as invoices and returns. If any exist, then the Billing application creates a report that tells you there are records that you need to update.

The Billing application also checks the input file for interface invoices.
