Verify a document

Enter a verification hash from a Chain of Custody document or demand letter to independently verify that an invoice audit trail has not been tampered with.

How it works
1.Find the verification hash on your Chain of Custody document or demand letter.
2.Paste it above and click Verify.
3.We recompute the entire hash chain from scratch and confirm whether the audit trail is intact or has been altered.

This verification is independent. Anyone can verify a hash without an InvoiceProof account.
