Issue documents. Prove delivery. Automate payment.
Tamper-evident transmittals with tracked acknowledgment and milestone escrow — for teams that can't afford ambiguity.
TransmittalProof replaces email-based document handoffs with a verifiable, auditable process. Every file is hashed at upload, every transmittal is externally anchored, every acknowledgment is timestamped — and milestone payments release automatically when deliverables are approved.
Proof, acknowledgment, and payment — connected.
Most teams handle these as three separate problems. TransmittalProof treats them as one workflow.

Six steps from upload to payment.
Every step produces a verifiable record. Nothing is lost between handoffs.
Upload & Hash
Upload documents. Each file is SHA-256 hashed at the point of entry — creating a permanent fingerprint before anything else happens.
Build Manifest
Group files into a transmittal manifest with metadata, revision codes, and distribution lists. The manifest itself becomes part of the proof chain.
Anchor Proof
The transmittal record is anchored externally with a timestamp. The proof is independently verifiable and does not depend on our systems.
Send & Track
Distribute the transmittal to recipients. Track who received it, when they opened it, and whether delivery succeeded — all in real time.
Acknowledge
Recipients confirm receipt with a single click. Their acknowledgment is timestamped and anchored — creating legally defensible proof of delivery.
Release Payment
When a milestone deliverable is approved, escrowed funds release automatically. No manual invoicing. No 60-day payment terms.
Built for teams that issue controlled documents.
If your industry requires proof that the right document reached the right person — TransmittalProof fits.

Your documents stay yours.
Proof of authenticity doesn't require exposing your files. Verification is public — content is not.
Account Isolation
Every workspace is fully isolated. Your data, users, and proof records are never shared across accounts.
Document Privacy
Files are encrypted at rest and in transit. Only authorized users within your workspace can access document contents.
Verification Without Exposure
Public verification confirms authenticity without revealing document contents. Recipients verify proof — not your files.
Private Workspace
Your tenant workspace is yours alone. No cross-tenant data leakage, no shared infrastructure risks, no surprises.
Common questions.
What is TransmittalProof?
TransmittalProof is professional document transmittal software that combines tamper-evident proof of issuance, tracked acknowledgment workflows, and automated milestone payments into a single platform. It replaces email-based document handoffs with a verifiable, auditable process.
How does verification work?
Every transmittal generates a unique proof record anchored to an external timestamp. Recipients can verify the authenticity of any document by visiting its public verification page — no account required. The proof confirms the document has not been altered since issuance.
Is it legally defensible?
Yes. Every action — upload, transmittal, delivery, acknowledgment — is timestamped and externally anchored. The audit trail provides evidence of what was sent, when it was received, and who acknowledged it. This meets evidentiary standards for most jurisdictions.
Which industries use TransmittalProof?
Engineering, construction, oil & gas, legal, government, architecture, manufacturing, mining, maritime, healthcare, financial services, and insurance teams all use document transmittals. If your team issues controlled documents and needs proof of delivery, TransmittalProof fits.
How do payments work?
You define milestones tied to deliverables. Funds are held in escrow and release automatically when the associated deliverable is approved by the recipient. Settlement completes in minutes. The full payment trail — from milestone definition to fund release — is part of the audit record.
Do recipients need accounts?
No. Recipients can view transmittals, acknowledge delivery, and verify proof through secure links — no sign-up required. If your team wants recipients to have tracked accounts, that option is available on Team plans and above.
Simple plans. No per-document fees.
