# Manual Billing Setup

**Manual Billing Codes** are setup to default G/L accounts on the financial sales document lines. If G/L accounts are left unspecified (blank) on the **Manual Billing Setup**, then the G/L accounts can be selected when creating the sales document. Financial or sundry sales documents require a **Manual Billing Code** to be selected when creating the invoice or credit memo.

The **Manual Billing Setup** also controls which financial sales documents appear on the **Billing and Income Report**, for example it may be necessary to exclude intercompany recoveries from the report, or populate only the sales value, or only the income value.
