How to Get Formal Client Sign-Off on a Website Project

"Yeah, looks great!" is not sign-off. It's a liability. Verbal approval has ended more agency-client relationships — and cost more money — than almost any other single problem. Here's how to build a proper sign-off process that protects everyone.

What happens without formal sign-off

These are real scenarios that play out in agencies every week:

""I never approved the mobile layout""

You rebuild a responsive design you already built and signed off — for free.

""I'm not happy with the homepage. I said that at the start.""

Without a written record, you can't prove they approved it. You rebuild it.

""I'm not paying the final invoice until X is fixed.""

Without sign-off, they can withhold payment indefinitely over any complaint.

""We launched and now I want changes to the navigation.""

If there's no formal completion record, "one more change" never ends.

In every case, written sign-off would have either prevented the dispute entirely or given you clear grounds to push back.

What formal sign-off should include

Sign-off isn't one document at the end. It's a series of approvals at key stages throughout the project — and a final comprehensive sign-off at delivery. Staged approvals prevent the "but I never liked the homepage" conversation because you have proof they approved it three weeks ago.

How to actually get clients to sign off

Clients are busy. They procrastinate on approvals. Here's what works:

Make it easy — not a PDF they have to print and scan

The more friction, the longer it takes. A digital checklist they click through in two minutes beats a formal document they'll ignore for two weeks.

Be explicit about what approval means

Don't say "let me know if you're happy with this." Say "Please click Approve on each item below. Once all are approved, we'll proceed to launch." Clarity drives action.

Gate progress on approval

Don't start the build until the design is approved in writing. Don't launch until the final checklist is complete. "We can't proceed until this is signed off" is completely reasonable — and protects both parties.

Create a timestamp

A record of what was approved and when is what actually matters legally. "Client approved homepage design on March 15th at 2:43 PM" is useful. "Client said it looked nice in a Slack message" is not.
