## What are Products?

Products are items you sell to clients, either as physical goods or services. They are managed in a product catalog and added to projects and invoices. Products help you track revenue from item sales separate from time-based billing.

> **Products vs. time entries — the key difference is the unit.** A product record is measured in **pieces (pcs)**, whereas a time record (time entry) is measured in **hours**. This is the fundamental distinction between the two: products count how many items or units you deliver, while time entries count how many hours you work.
>
> **When to use Products:** If your price list should include a product or service that carries a **fixed fee** rather than an hourly rate, products are the way to go. In other words, use Products when you want to bill a fixed-fee item or service at a **per-piece price** instead of billing hourly time.

## Why Products Matter

Using products helps you:

- **Track item sales** - Record revenue from physical goods and services
- **Streamline invoicing** - Add products to invoices quickly with standardized rates
- **Analyze revenue** - See which products generate the most income
- **Separate from time-based billing** - Track product revenue independently from hourly work, because products are billed per piece (pcs) at a fixed price rather than per hour

## Creating a Product Entry

To add a product to a project:

1. Navigate to the project where you want to add the product.

2. In the project's billables section, click the **Products** link to view the products list.
