A compliance hub for companies that invoice in several countries. Helios checks, converts, repairs and sends e-invoices, and warns you before a rule change or a rejection costs money.

One place for the e-invoice formats and rules of the world. Interline places every format on one shared invoice model, built on the Peppol PINT semantic model, so a real invoice can be traced field by field between any two formats, converted, and checked against the published rules of both.
