Version-bound sign-off
Approvals attach to the specific file hash reviewed. A later revision needs its own approval — no retroactive blur.
Feature · Client approval
Client approval, recorded — not buried in chat
Send one link. Your client reviews the work and approves with a tap. The sign-off is recorded with a UTC timestamp against the exact version they saw — so “I never approved that” stops being a conversation.
“Looks good!” in WhatsApp is not an approval
Most freelance disputes are not about bad work — they are about fuzzy sign-off. A thumbs-up emoji, a verbal OK on a call, a “go ahead” buried in a 300-message thread. When scope questions or payment delays come later, nobody can point to what exactly was approved, or when. You need approval that is specific to a version of the work, recorded somewhere neither side can quietly edit.
Who this is for
- Freelancers who deliver work in review rounds
- Agencies that need client sign-off before production
- Anyone who has lost a payment argument over a vague OK
- Teams replacing email threads with a single source of truth
How it works
- 1
Upload the version to review
Add the deliverable to a project. Proofmark hashes the file with SHA-256, so the approval is tied to those exact bytes.
- 2
Send the approval link
One tokenized link, shareable over email or WhatsApp. No client account needed — clients hate signing up for your tools.
- 3
Client reviews and signs off
The client sees the work, the scope, and an unmistakable approve action. Rejections come back with written feedback instead of a phone call.
- 4
The record is kept for both of you
Timestamp, IP address, version, and signature are recorded, and a proof certificate is generated that either side can verify online.
Recorded rejection feedback
When a client requests changes, their written reason is stored on the project, not lost in a call.
No client login
Clients approve through a secure tokenized link. Zero-friction for them, recorded evidence for you.
Certificate on approval
Every approval can produce a proof certificate with a public verification URL you can share.
Frequently asked questions
Do my clients need a Proofmark account?
No. Clients open a secure link, review the work, and approve or request changes. Only you need an account.
What exactly gets recorded when a client approves?
The approval timestamp (UTC), the IP address it came from, the client's signature, and the SHA-256 hash of the version approved. You can export it all in a proof packet.
Is a recorded approval legally binding?
Proofmark keeps honest, timestamped records of approval, delivery, and payment status. Whether a record is enforceable depends on your contract and jurisdiction — Proofmark is not a substitute for legal advice.
Can I require approval before final files are released?
Yes. Combine approval links with payment-gated delivery so final files unlock only after sign-off and payment confirmation.
