# Products

### Definition

A product is an item or service that can appear on an invoice line. It holds a name, a description, a unit price, and optionally a default tax rate.

### Purpose

Products standardize what appears on invoice lines. They avoid re-entering the same item details on every invoice.

### Relationships

* Referenced by invoice lines.
* Can have a default tax rate.
