 ## Analyze costs with customizable views
 
 While smart views offer a highly curated experience for targeted scenarios, custom views allow you to drill in further and answer more specific questions. Like smart views, custom views include a specific date range, granularity, group by, and one or more filters. Five custom views are provided for you to show how costs change over time. They're separated by resource and product. All aspects of custom views can be changed to help answer simple questions. If you require more advanced reporting, like grouping by multiple attributes or fully customizable reports, use Power BI or export raw cost details.
