Create a product library of the goods and services you sell, then associate them with individual deals. With products, you can easily track what you're selling to your customers. When you associate a product to a deal or quote, you are adding a line item, which is one instance of that product. Review the differences between a product and a line item:
Product: a product represents a good or service that you sell. You can create and manage products in the product library.
Line items: when you associate a product with a deal record or a quote, you are associating one instance of that product as a unique line item. The line item is no longer connected to the product, and any updates to the original product's information in the product library will not apply to the line items that are already associated with your deal records.
This article will go over how to create and manage products in the product library. To edit your line items, learn more about using the line items editor.
