What Is Approval Lock? Explicit Client Sign-Off for Creative Work
Approval Lock™ explained: why chat reactions are not approvals, how Definition-of-Done gates work, and how locked approval opens payment release.

A 👍 in Slack is not an Approval Lock. A "looks amazing!" email is not one either. On creative projects, informal praise creates payment disputes because nobody recorded who accepted which version when.
Approval Lock™ is Zlaip's primitive for immutable client sign-off, explicit, attributable, and tied to milestone gates. This glossary-style guide explains what it is, when it applies, and why it matters for freelancers and clients.
Approval Lock in one sentence
Approval Lock is a deliberate, immutable record that a designated approver accepted a specific deliverable version after every Definition-of-Done item for that milestone was complete.
It is not a mood. It is not a reaction. It is accountability.
What must be true before Approval Lock
Gates fire in order:
- Agreement Lock™, terms, scope, and revision limits are sealed
- Creative submits milestone deliverable → recorded in timeline
- Revision rounds consumed within Revision Boundary™ (or change order for extras)
- Every Definition-of-Done item marked complete
- Designated approver performs explicit Approval Lock
Skipping DoD turns approval into guesswork about whether the work was actually finished.
Approval Lock vs common substitutes
| Substitute | Why it fails |
|---|---|
| Chat reaction | No version binding; any participant can click |
| Verbal OK on Zoom | No durable record; he-said/she-said |
| Email "approved" without version | Ambiguous which file was accepted |
| Payment as implicit approval | Client may dispute quality after paying |
Proof of client approval for disputes and escrow release needs the first column: person, version, timestamp, explicit action.
What happens after Approval Lock
Once locked:
- The approval record is append-only, not edited or deleted
- Payment Release Gate™ may open, invoice draft, send, or milestone escrow step
- The Vault retains hash-chained evidence alongside submissions and revisions
Clients get clarity on what they owe; creatives get a defensible basis to invoice.
Can approval be undone?
Approval Lock is immutable by design. If something was wrong:
- Open a revision request only if rounds remain, or
- Execute a change order for new scope, or
- Resolve through dispute process if parties disagree
Silent "un-approval" in chat does not rewind a locked record.
How clients approve deliverables online
In Zlaip's client approval workflow:
- Review submission in Accountability Chat
- Request revisions (within limit) or
- Confirm DoD complete and lock approval explicitly
Stakeholders may view progress without binding authority if the contract names a single approver.
Bottom line
Approval Lock is how creative work gets a real deliverable approval, not vibes in a side channel. It protects both sides and opens the path to payment release on shared facts.
