Concept

When einvoice is subject to e-reporting, then you upload the Invoice to Billit. When no e-reporting is applicable, then it does not have to be uploaded to Billit.

Status : Invoice will be e-reported

when invoice or Credit Note is stored in Billit,
regardless whewhether invoice is stored and not sent, or sent
exception : invoice should not have status draft
when conditions are met (e-reporting period, B2C or B2Bi)

Upload can be automated via API
