Report- save revenue by date

Hi,

Our intention is to organize clients in 2 main groups: Leads and Active Clients ( with contract ongoing) for instance.

So this is our case study for Active Clients: in one group we have 3 clients :

  • Client 1 with 100 euro/ month, start contract on January

  • Client 2 with 200 euro/ month, start contract on February

  • Client 3 with 300 euro/ month, start contract on March

So, in April or at some point in the future, in a revenue evolution report, should we be able to observe in a graphic/ bar all these values per month (January, February and March)?

It is very important for us to obtain this type of report.
Thank you,
Roxana
