BIX Compliance Gateway

One connection for compliant e-invoicing and e-reporting

BIX Compliance Gateway

E-invoicing and digital reporting are now essential for doing business in many markets. Governments are setting rules on how invoices must be issued, received, reported and stored. While the goals differ – from improving tax transparency and reducing fraud to strengthening payment discipline and speeding up digitalisation – the outcome is the same: more structured and regulated invoicing.

For companies operating across borders, this creates complexity. Each country has its own models, reporting rules and technical standards, requiring constant monitoring and system updates.

BIX Compliance Gateway makes it simple

As part of Tieto’s B2B e-invoicing services, it offers secure, standardised connectivity to national e-invoicing and tax authority platforms – all through a single integration

Instead of building and maintaining multiple country-specific connections, you connect once to BIX. We handle local integrations, regulatory updates and authority connections. This ensures business continuity while reducing technical and operational effort.

The service supports organisations operating in regulated markets that need reliable, scalable and compliant invoice exchange.
