Rollup of Invoices from Zoho Finance/Books

Rollup of Invoices from Zoho Finance/Books

Hi, 

I am looking at taking data from Zoho  Finance/Books  adding them to an account within the accounts module

Products purchased - and adding them via a related list
Total GBP invoices paid (rolling up) everytime a new invoice is paid

is this possible between the two applications?

Thanks
