# Opportunity Products Overview

> Add products to an Opportunity with the Opportunity Products button so you can price a potential sale before converting it to an Order.

## What This Section Covers

Adding **products** to an Opportunity captures exactly what a member or organization is considering buying — memberships, event registrations, sponsorship packages, training programs, and more. Pricing the Opportunity this way lets you forecast the sale and gives the conversion the line items it needs: converting an Opportunity to an Order requires at least one product.

You add products with the **Order Entry** component, which appears on an Opportunity as the **Opportunity Products** button. Each product you add creates an `OpportunityLineItem` record on the Opportunity.

## Key Concepts

* **Opportunity Products** — the button on an Opportunity that opens the Order Entry component so you can search for and add products.
* **Opportunity product** (`OpportunityLineItem`) — a single product line added to an Opportunity.
* **Product search** — the search box inside Order Entry where you find products to add.
