From supplier data validation to a registry-ready annual declaration — with a sealed audit trail at every step, not just a spreadsheet with extra columns.
Start for freeValidate 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.
