Need help to get a functionality using slicer

Hello every one,

I am building a report and want to minimize the number of pages. My data model has accounts table and a clients table. My report has a page which shows the number of accounts with sales (for example), I am thinking of using a slicer which has two values client and accounts so that if user clicks on accounts the visual shows number of accounts and if user clicks clients , the visual shows number of clients, but I have no idea how to achieve that. 

Could somebody provide me any direction here?

Thank you
