# Bill Line Items - Default Descriptions

1When setting up priced Product Plans and Prepayment or Balance amounts to apply usage-based or unit-based charges against your end-customer Accounts for consuming Products, there are several places where you have the option to define custom descriptions for Bill line items:

* **Plan Templates/Plans**: Standing Charge and Minimum Spend descriptions.
* **Plan Groups** - Standing Charge and Minimum Spend descriptions.
* **Pricing** - Usage and Minimum Spend descriptions.
* **Counter Pricing** - Recurring subscription charge descriptions.
* **Prepayments** - Fee, Usage, and Overage descriptions.
* **Balances** - Draw-down description, one-off Charge description.
* **Accounts** - Charge description.

This topic explains how Bill line item default descriptions are compiled *if you omit custom descriptions for Bill line items.*

## Parent/Child Account Bills - Line Item Descriptions

Default descriptions for line items that appear on Bills where there is a Parent/Child Accounts set up follow the same rules for compiling the DESCRIPTION text, except the *name of the Child Account* is also appended to the default description text string.

<Warning>
  **Warning - Case where Child Account code also shown in description!** If you have the Account Plan attached to the Parent Account and set the **Account hierarchy billing mode** to **Bill parent account - bill line item per account**, then the Bill for the Parent Account will append both the Child Account **name** and **code** to the description text for any Child Account usage charge line items.
</Warning>
