Quantity of tickets. and total time worked for each client

[rslemer]

I wish a report with a quantity of tickets, open and closed, in month, for each client

In fact, I wish the quantity, total number hours worked, for calculate a invoice for each client

My client, can be open a ticket thru email, and I did scheduler the mail scanner to get this email and open a ticket.

First problem, is system only associate ticket with my client, if email sender in account. For this problem, is possible system associate ticket a account for all contact emails, associate a this same account ?

Example

Account 1 - email account@account.com.br
Contact1 - email contatc1@account.com.br ( this contact is associate a account, previously .. )
Contact2 - email contact2@account.com.br ( this contact is associate a account, previously .. )

I wish, sender is account@account,com.br, contact1@account.com.br, contact2@account.com.br associate ticket open thru mail scanner a account.

Or that is another way, I get this report ?
