How do your clients sign off on work today?

Hi all, I'm Denzil, the solo founder behind TweakTick. It launches here tomorrow (Thu 12 Nov).

TweakTick does two things. Clients leave feedback pinned right on your live site, images, PDFs or video. Then they approve each round with a 6-digit code from their email. Clients never create an account.

Before building it I read 601 reviews of feedback and proofing tools. The two biggest complaints:

1. Clients won't sign up or install anything just to leave feedback.

2. Prices and plans keep changing.

So I'd love to hear from freelancers and agencies:

• How do you record a client's sign-off today? Email, a call, a checkbox in some tool?

• Has a "we never approved that" ever cost you time or money?

• Would an emailed-code approval feel too formal for your clients?

Thanks, I'll reply to everyone.
