Getting Client Sign-Off on Completed Work

A job isn’t finished when the work is done — it’s finished when the client agrees it’s done. A signature at completion converts “we’ll see” into acceptance, and it takes ninety seconds when the form lives on your phone.

Why sign-off changes the psychology of getting paid

Without sign-off, the moment of acceptance is fuzzy — it happens silently, sometime between your last day on site and the invoice due date, and the client controls when (and whether) it happened. With sign-off, acceptance is an event: a specific person, on a specific date, looked at the work and formally agreed it was complete and satisfactory. Payment disputes need ambiguity to live; a signature removes it.

There’s a softer benefit too: asking for sign-off reads as professionalism, not suspicion. It’s the same move a delivery driver or an equipment rental company makes — nobody is offended by it, and it quietly signals that your business keeps records.

What a good sign-off includes

Paper forms vs. e-sign platforms vs. on-device

Paper gets lost, lives in the truck, and separates the signature from the photos it refers to. Email e-signature platforms (DocuSign and friends) work, but they move the moment of acceptance to “later, at their computer” — which is exactly the delay you’re trying to eliminate, and they typically cost a monthly subscription. On-device sign-off keeps the moment where it belongs: the client is standing in front of the finished work, the photos are on the screen, and the signature happens now.

How SiteProof seals it

SiteProof’s sign-off isn’t a picture of a signature floating in a photos folder. The signature, the signer’s name, the agreement text, and the timestamp are cryptographically sealed together with the job record (HMAC-signed on your device). The sign-off then appears in the PDF job report in its own card, and it’s included in the exportable evidence package alongside the photos and proof manifest.

Scope note: SiteProof’s sign-off is an acknowledgment of work completion — the app tells clients this on the signing screen — not a substitute for your contract. For binding agreement language, consult a professional. Acceptance-at-completion plus your contract is the combination that protects you.
