Client sign-off
The dated proof that the client approved a specific deliverable, so the project can move on without reopening the last phase.

What it is
Client sign-off is a dated record that an authorized client contact reviewed a specific version of a deliverable and accepted it against the agreed criteria. It can be a signed form or a recorded approval in the project system. The useful part is not the ceremony. It is the link between one named version, one approver, and one decision.
Reach for sign-off at phase boundaries: approved wireframes before visual design, approved designs before development, and an accepted final build before handoff. Print has done this for a century with the bon a tirer proof, French for good to pull: the client signs the physical sheet, and that signed sheet is what the press run is judged against. Copy the discipline, not the paper. Record the deliverable name, version or URL, acceptance criteria, known exceptions, approval date, and what the approval triggers, such as the next phase or a milestone invoice.
Gotcha: 'looks good' in a busy chat thread does not identify what was reviewed. Freeze the version and route approval through the person named in the contract. Sign-off also does not make later changes free: a revision after approval is a change request, not a reopened round.

Create a DocuSign client sign-off form for the deliverable below. Include project and SOW references, deliverable name, immutable version number or URL, acceptance criteria as checkboxes, known exceptions, the approval decision, approver name and authority, date, signature, and the milestone invoice triggered by acceptance. Add a short statement that later changes to the approved version require a change order. Keep it to one page and do not use a vague 'looks good' approval.
