It is recommended to use the integration for a simulation of the software house's own billing, allowing the billing team to view the electronic invoice prototypes and compare them in parallel with the physical invoices generated ( even without having an electronic billing resolution). In this way, your own accounting and tax team can provide feedback on the quality of the integration.
