## Deleting Inventories

Unbilled inventories can be deleted if needed.

**Delete Usage Product Inventory:**

Use `DELETE /usage-product-inventories/{id}` to remove an unbilled usage product inventory.

**Delete Rental Product Inventory:**

Use `DELETE /rental-product-inventories/{id}` to remove an unbilled rental product inventory.

**Important:** Only unbilled inventories can be deleted. Once an inventory has been included in a bill, it cannot be deleted.
