Price Books allow you to create pricing schemes based on different sales tracking codes or on an activation date. Instead of creating multiple catalog plans with different prices to be used, you can use a price book and a sales tracking code or date to use a catalog with an appropriate price easily.
You can create pricebooks to simplify pricing. Pricebooks can then be selected when creating subscriptions or products to select a pricebook to determine a price.
For example, you can have a subscription priced at $35.50 for your Tampa clients and $20.50 for your Orlando Region clients on the same plan. Using the sales tracking code, the price book will determine the price to apply.
Use a future date to automatically set renewal pricing. This also allows you to see a history of past pricing.
