What CBAM reporting software actually needs to do

Validate incoming supplier data

Catch missing fields, unit mismatches, and out-of-range values before they reach a declaration.

Track the reporting calendar

Every deadline — declaration, verification, certificate surrender — in one place, not a separate spreadsheet.

Distinguish default from actual values

Flag which line items still rely on the regulatory default markup vs. verified supplier data.

Keep a sealed audit trail

Every calculation record traceable and tamper-evident, ready for verifier or customs review.
