What is the Revenue Schedules feature in Vtiger CRM?

The Revenue Schedules feature is a combination of fields that record Revenue Schedules for a product or service, including the price, duration, etc. 
It impacts the Deals, Products, and Services modules directly. 
When a product or a service with Revenue Schedules is added to a deal, the deal is automatically updated with this information from that product or service record, helping you create a deal effortlessly and without errors.
