Mapping Reference

A-Cube Transfer converts the files you send into the e-invoice format required by each country's tax authority, such as FatturaPA in Italy and KSeF FA(3) in Poland. You keep the format you already produce:

• UBL (Universal Business Language), a standard format for business documents, as XML or JSON.
• The A-Cube standard CSV, one row for each invoice line.
• Your own format, through a custom CSV format that A-Cube builds for you.

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

• Source and target fields: which field of your file maps to which field of the national e-invoice
• 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.
