Document Management | Audit Evidence Packs
Per-filing evidence packs assemble themselves. Hash-verified at export.
The state sales tax return for last quarter? The pack carries the return, the workings behind each figure, the underlying invoices, the exemption certificates as they stood on each sale date, the filing confirmation and the proof of payment. The annual report? The records, the supporting entries and the sign-off. One click, hash-verified at export.

Compliance + integrations
Audit packs the auditor and the regulator both accept.
The pack is assembled in the form an engagement file takes, so it goes to your auditor rather than being taken apart and rebuilt by them. The hash-verified chain is what lets them rely on it without re-vouching the source.

Audit Evidence Packs FAQ
What buyers ask.
How is the hash chain verified independently?
The pack carries a verification key and a small command-line tool. The auditor runs the verification against the archive; the tool confirms each file hash against the chain and the chain root against the signature. Any mismatch flags. The verification is cryptographic, not based on metadata.
For a tax notice from FY 2018-19, can we still pull the pack?
Packs stay re-assemblable for as long as the underlying records are retained. Re-assembling a return from three years ago works exactly like re-assembling last quarter's, and the hash chain stays intact across the whole retention period, which is the part that matters if anyone questions whether the evidence changed.
What if the auditor wants to add their own working papers to the pack?
Auditor working papers can be uploaded against the pack with auditor sign-off. They become part of the audited pack with their own hash and audit trail. The pack signed by both the auditor and the system carries dual integrity.
