# Line-item library

The line-item library stores lines you bill again and again: products, services and freight. Each one keeps its description and rate.

- **While raising an invoice:** search the library and insert a saved line. You can also save any line from an invoice into the library.
- **Managing the library:** **Invoicing → Line item library** lists everything saved, where you can edit or delete lines. Managing the library needs the *Line Item Library → Manage* permission, separate from raising invoices.
