Hi Edward,
Transferring data between companies will always mean Export and Import. What do you mean by 'not working'?
What version of Adagio Invoices are you using? If version 8.x then there is only one format to export and re-import. If version 9.0X then there are definable templates for both Export and Import, which have to match for column layout.
