ZUGFeRD EXTENDED profile

The EXTENDED profile provides additional data elements for sector-specific or advanced processes beyond the core EN 16931 model.

Recommended for

Organizations with advanced integration requirements
Sector-specific data needs (where supported by recipients)

What it typically includes

Extra reference data and additional business information
More granular line-level and tax details (where applicable)
Extensions that some systems can process

Limitations

Not every recipient supports EXTENDED fields
May reduce interoperability if recipients expect strict EN 16931

Typical use cases

Sector projects with agreed extensions
Complex enterprise invoice integrations where both parties align on the data set
