How do I import Invoices from Freshbooks?

We're wanting to move from Freshbooks (FB) to Zoho Invoice for a few reasons.

We have a lot of invoices in FB and would like to move them over. For some reason FB's invoice export is very weak - it only exports: invoice_number organization fname lname amount paid po_number create_date date_paid terms,notes

Is there a widget or a way to port the invoices over using the APIs? It is literally impossible to do with the FB export - it simply lacks the info needed for the ZOHO import.
