Before & after photos, on the certificate.
Don't just say the job's done — show it. Engineers capture before and after photos on site, 1 Sign verifies they were taken during the job, and they're embedded in the signed PDF certificate your customer receives.
Why photo proof matters
A signature says the customer was happy. Before and after photos show exactly what they were happy with — and protect you long after you've left site.
End "he said, she said"
Disputes about the condition of a site or the standard of work are settled in seconds when the certificate shows the before and the after, side by side.
Protect your workDate-verified, not dug up
Tell 1 Sign roughly how long the job lasted and it only accepts photos taken in that window. Old photos from the camera roll are rejected automatically.
See it in actionLook like the pros you are
A branded certificate with photos, signatures and a unique reference is marketing as much as paperwork — proof of quality your customers can forward on.
Brand your certificatesHow it works
Built into the same sign-off your engineers already complete — no extra app, no uploading later from the office.
Snap on site
The engineer takes before photos as they arrive and after photos when the work's done — straight from the sign-off form, camera or gallery.
Checked against the job
1 Sign asks how long the job lasted and verifies every photo was taken within that window, so the evidence is genuine.
On the certificate
The photos are embedded in the signed PDF certificate and emailed to your customer instantly — and stored in your control panel forever.
Photo proof of work, for every trade
Whether you're servicing commercial doors, rewiring a unit, deep-cleaning a kitchen or repairing storm damage, before and after photos answer the question every customer and every dispute comes down to: what did the site look like when you arrived, and what did it look like when you left?
Paper job sheets can't carry photos. Texting them to the office loses them. 1 Sign keeps the photos, the customer's signature and the job details together in one signed, time-stamped PDF completion certificate — emailed to the customer before your engineer leaves site and searchable in your control panel whenever you need it again.
