Mapping Reference

A-Cube Transfer accepts invoices in a single, unified input format based on UBL (Universal Business Language) and automatically converts them into the specific e-invoice format required by each country's tax authority.

You send one UBL invoice — we handle the translation to KSeF (Poland), FatturaPA (Italy), and every other national format we support.

This section provides detailed, field-by-field mapping references for each supported country. Every page below documents:

• Source and target fields — which UBL field maps to which national e-invoice field
• Transformations — value mappings, date formatting, regex extraction
• Conditions — when a field is included or excluded based on invoice content
• Default values — fields that are automatically populated when not present in the source

These references are auto-generated from the mapping configuration used in production, so they always reflect the current behavior of the system.
