Q&A BIX Compliance Gateway

Provides secure, standardised access to national e-invoicing and tax authority platforms through one connection, helping businesses stay compliant across markets.

What is Compliance Gateway?

BIX Compliance Gateway is a service that helps organisations meet national e-invoicing and digital reporting requirements through one secure connection. It provides access to national e-invoicing and tax authority platforms while handling local integrations, required formats and regulatory updates. The service supports both B2B and B2G invoicing models and is designed for businesses operating in regulated markets.

How does it work?

Instead of building and maintaining separate integrations for each country, businesses connect once to BIX. The platform then manages connections to supported tax authority systems and national e-invoicing platforms. BIX also monitors regulatory changes, handles format requirements and maintains integrations to ensure compliant and reliable invoice exchange across multiple markets.

Why should I use Compliance Gateway?
