Both signatures, on the report your customer keeps
A record produced by Maintivo from a sample visit, with the engineer’s and the customer’s signatures, the findings and the photos on your letterhead.
On your iPhone on site. On Android, a tablet or the office computer too.
One account for the whole firm. A report an engineer finishes on site is on the office screen as soon as it uploads, and a customer added at the desk is on every phone.
- iPhone: the app. It works with no signal and uploads when you are back in range.
- Android phones, iPads and other tablets: the web app at app.maintivo.com. Add it to the home screen and it opens like an app.
- Laptop or desktop: the same web app on a big screen, for reviewing reports, clients, invoices and the team.
- Always in step: the same reports, customers and PDFs everywhere. One subscription covers all of it.



The arguments a signature on the day prevents
Before“You never did that.” And you have nothing signed to show.
With MaintivoThe customer signs the report on your phone before you leave, next to the photos of the work.
BeforeThe invoice gets queried because the job was never signed off.
With MaintivoA signed report can become an invoice the same day with the invoicing add-on.
BeforeA paper sign-off sheet goes missing in the van.
With MaintivoThe signed PDF is stored against the customer and sent to them by email.
BeforeEvery engineer gets sign-off a different way, or not at all.
With MaintivoEvery form ends with the same sign-off step, for every engineer.
Why sign-off on the day matters
The week after a job is when the questions start: “you never did that”, “that was already broken”, “we did not agree to that part”. A signature on the day, on a record that shows what you found, what you did and the photos to prove it, ends most of those conversations before they begin. It also lets you invoice the same day, because the customer has already agreed the work was done.
How sign-off works in Maintivo
- Fill in the job on site: what you found, what you did, readings and photos
- Sign on the screen, then hand the phone to the customer to sign
- If the customer would rather not draw a signature, record that instead, so the report says so
- The PDF with both signatures, your logo and the photos is ready to send before you leave
- Engineers cannot change a report once the owner or an admin has closed it
Is an electronic signature valid?
For most job sheets there is no legal requirement for a customer signature at all; it is simply the clearest proof that the work was done and accepted. Under the Electronic Communications Act 2000, section 7, an electronic signature can be used as evidence of whether a document is genuine. What makes a signature worth having in practice is that it sits on the right record, with the date, next to the work it confirms. For gas safety records, HSE accepts an electronic signature as a way of identifying the engineer.
Any job, any trade
Use sign-off on a general job sheet, a service visit, an inspection, a commissioning record, a gas safety record or an F-Gas leak check. Every form ends with the same sign-off step, so every engineer in your team gets the job signed the same way.
On iPhone, Android, a tablet or a computer
The iPhone app works with no signal and uploads the signed record later. On Android or a tablet, the web app at app.maintivo.com does the same sign-off in the browser, on the same account.

Common questions
Electronic signatures can be used as evidence in the UK under the Electronic Communications Act 2000, section 7. For most job sheets no customer signature is legally required, but a signature on the day is the simplest proof that the work was done and accepted. For landlord gas safety records the signature the law requires is the engineer’s.
Record that the customer preferred not to sign, so the report says so, and keep the photos and notes of the work. A dated record of the visit is still useful evidence.
No. They sign on your phone or tablet. They get the signed PDF by email, and can ask for a printed copy.
Engineers cannot change a report once the owner or an admin has closed it. The owner can see every report as it comes in.
Yes, with the optional invoicing add-on: a signed report becomes an invoice with VAT, a deposit and payment terms, so the job can be invoiced the same day.
