Client sign-off: how to get a client to approve your work

By the Docmend team · Updated 16 October 2026 · 5 min read

Short answer

A client sign-off is written confirmation that a deliverable or a project stage is accepted. Put what’s being approved in one short document, then get it confirmed: by reply email, by a signed PDF, or by a signing link that records who signed and when. The Docmend Chrome extension, which gets Google Docs, PDFs and Word files reviewed and signed from one link, handles that last route.

What does client sign-off mean?

Sign-off is the moment a client says “yes, this is done”. It can cover a whole project or one milestone: the brand concepts, the first draft of the copy, the staging site, the final report. Getting it in writing matters for practical reasons:

Scope: when a new request arrives after sign-off, you both know it’s a change, not part of the original job.
Invoices: many freelancers invoice a milestone once it’s approved, and a sign-off makes that moment clear.
Revisions: it closes a round of feedback so the next round starts from an agreed version.

What a sign-off means in a dispute depends on your contract and where you work. This guide is about getting a clear, recorded approval, not legal advice.

What to put in a sign-off form

Checklist

Project and deliverable name
Version number or date of the deliverable, so nobody approves the wrong file (to check what changed between two versions, use Compare PDF or Text compare)
What’s included
What’s out of scope
Open items you’ve agreed to handle later
Approver’s name and role
Date and signature

Copy-paste template

Paste this into a Google Doc or Word file, fill in the brackets, and delete what you don’t need. It is a plain starting point, not legal language; if your contract defines acceptance, follow its wording.

Keep it to one page. A sign-off the client can read in a minute gets signed faster than one that reads like a contract.

Way 1: Approval by email (free)

Send a short email that summarises the deliverable, using the checklist above, and ask the client to reply “Approved”. Attach or link the final version so the approval clearly refers to it.

It is quick and costs nothing, and most clients will do it. The downside is that approvals end up scattered across inboxes and threads, and a one-word reply is easy to lose or to argue about later. If you go this way, file the email with the project and save a PDF of the approved version.

Way 2: A signed PDF (free)

Fill in the template and save it as a PDF. In Google Docs, choose File → Download → PDF document. In Word, choose File → Save As (or Save a Copy) and pick PDF.
Email the PDF and ask the client to sign it and send it back.
They sign it in an app they already have, such as Chrome’s PDF viewer, Preview on a Mac, or Markup on an iPhone. Our guide on how to sign a PDF without Adobe covers their side, if they ask.

You get a signed document instead of a reply, which is easier to file. It still depends on the client signing correctly and remembering to return it, and you get no record of when it was opened or signed. For more on the options, see how to get someone to sign a document online for free.

Way 3: Review, then sign from one link (Docmend)

Collect the last notes on the deliverable

Sign-off goes more smoothly when the last round of comments is settled first. With Docmend you send a review link for the Google Doc, PDF or Word file. The client opens it in any browser, highlights text and leaves notes with just their name, and can also approve or sign. The link is read-only, so they can’t change your file. For the full feedback workflow, see how to get client feedback on a document.

Get the sign-off signed

Open the sign-off form as a Google Doc and choose Send for signature, or upload it as a PDF. Docmend turns a Doc into a PDF.
Tap where the client should sign, and add name and date boxes.
Enter the client’s email, or copy the signing link and send it yourself.
The client opens the link, draws or types a signature, and clicks Finish. No account.
The signed PDF is emailed to you both, with a signing certificate as the last page.

The certificate records the time, the signer’s email and a fingerprint of the document; see what the signing certificate shows and how both sides get the signed PDF. If you need a record of the approval, use the signature request rather than relying on a note in the review link. Docmend has a free plan, and Pro at $4 a month or $36 a year.

Which way fits?

Way	Cost	Record you keep	Client needs an account	Best for
Email approval	Free	The reply email	No	Small, informal milestones
Signed PDF	Free	The signed PDF, if it comes back	No	One-off sign-offs with patient clients
Docmend review and signing link	See Docmend pricing	Signed PDF with a signing certificate, emailed to you both	No	Deliverables that need notes first, then a signed approval

Sign-off for design and video work

Designs, websites and videos are hard to approve from a written summary alone. A short screen recording where you walk the client through the final version helps. Docmend Video lets you record your screen or camera in the browser and share one link; the client comments on the exact second they mean, or replies with a video, and neither of you needs an account. Once the comments are resolved, send the sign-off form for signature as above.

Docmend’s signing links provide simple electronic signatures (drawn or typed signature, name, date, signing certificate). For contracts that need a certified or qualified e-signature, use a dedicated signing service.

Common questions

Is an email approval enough?

It depends on your contract and your jurisdiction, so ask a lawyer if it matters. A signed sign-off form gives you a clearer record than a one-word reply. See our answer on whether an electronic signature on a PDF is legally valid.

Can the client sign on a phone?

Yes. A Docmend signing link opens in a mobile browser, so the client can sign on a phone or a laptop with no account.

Can the client change the document?

No. A Docmend review link shows a read-only copy. The client can highlight text, leave notes, and approve or sign, but can’t change your file. See can a reviewer edit my file from a comment link.
