Sealed invoices cannot be deleted or amended. Corrections issue a credit note that references the original — the trail your auditor expects.

CHAPTER 02

Cryptographic seal

Each invoice receives a SHA-256 fingerprint at issue. Recipients verify integrity independently — no account, no login, no trust required.

CHAPTER 03

Audit binder export

Year-end produces a single signed PDF containing every invoice, hash, actor, and timestamp — formatted for SOC 2, ISO 27001, and statutory review.
