What is an Evidence Pack?

What's in an Evidence Pack?

Light Evidence Pack (Free)

• JSON validation report
• List of issues found and fixes applied
• SHA-256 hash of original and fixed files

Full Evidence Pack (Pro/Business)

• Everything in Light, plus:
• Original invoice file (before fixes)
• Fixed invoice file
• Detailed change manifest (XPath, before/after values)
• PDF summary report
• Timestamp certificate
• All in a single ZIP archive

Cryptographic Verification

Each Evidence Pack includes SHA-256 hashes:

• Original hash: Proves the original file hasn't been modified
• Fixed hash: Proves the fixed file is exactly what we generated
• Pack hash: Proves the Evidence Pack itself is authentic

For Auditors and Compliance

E-invoicing mandates often require proof of validation. An Evidence Pack provides:

• Timestamped proof: When was the invoice validated?
• Rule reference: Against which EN 16931 rules?
• Change documentation: What was modified and why?
• Cryptographic verification: Has anything been tampered with?

For Internal Records

Even without an audit, Evidence Packs help you:

• Track which invoices were auto-fixed
• Understand what changes were made
• Prove compliance at any point in time

For Disputes

If a customer or supplier questions an invoice, you have complete documentation of its state at validation time.
