Products feature is available in Sales Pack.
Product items can be used with Opportunity, Quotes, Sales Orders and Invoices. They are also available for a customization in Entity Manager so you can create new relationships between products and other entities.
A product record has three price fields: Cost, List and Unit. There is the ability to automatically calculate Unit Price using different formulas according to a selected Pricing Type.
The product can be marked as Tax-free. It will prevent applying the tax rate upon adding the product to a quote, sales order or inbvoice.
Products can be added as line items to a Quote record. Product fields can be printed in PDF. More detail here.
Opportunity line items¶
Products can be added as line items to an Opportunity record. By default this feature is disabled. Administrator needs to add Item List field to Detail layout of Opportunity in Layout Manager. Make the cell full-width wide using minus icon.
Each product record can belong to some product category. Product Categories are presented as a hierarchical tree structure. Each category can have sub-categories.
Product Category is a separate entity type, hence an access can be controlled by ACL.
