Hello,
I have extensive experience with Odoo development, specifically with Studio, and have successfully completed similar projects in the past. I am familiar with the fields you have listed, including Bank account, Bank name, BIC, Exchange rate, Invoice value, Currency invoice value, Payment terms, and Contratto, and understand the necessary steps to add these fields to the invoice report.
In terms of my approach, I will begin by selecting the appropriate object from Block, Inline, Table, Column, and setting their properties according to your requirements. I will then add the new fields to the report and make any necessary modifications to existing fields and labels.
Timeline: I estimate that the work will take approximately 7-10 business days to complete, depending on the complexity of the modifications required. Cheers
