The product, in numbers.
Reports, done on site.
The engineers at Mainteniq were doing certificates and reports on paper, or on a laptop in a plant room. Small service firms of any trade end up spending their evenings typing up the day.
Run the whole job from a phone. Fill in the form on site, take the photos, get the customer to sign on the screen, and the signed PDF report is done before you leave.
A system, not just an app.
Maintivo started as a way to fix one workflow: the engineers at Mainteniq finishing their paperwork at night. We mapped the job from the first form to the final invoice, then built each step so it runs from one phone, synced with the web app in the office. It is the same approach we use for any business through custom workflow automation.
Reports are filled in and signed on site, instead of typed up in the evening, and the customer has a branded PDF before the engineer leaves.
Any small firm that repeats the same job steps can run them like this. See the Mainteniq case study, or custom workflow automation for how we map and build yours.
Six things it does.
Ready-made forms
Pick a form for your trade, tap through it, and the report builds itself. Nothing to set up first.
Photos and notes on site
Yes, no or not applicable, with a note. Photos go into the report as you take them, and it keeps working with no signal.
Signed on the spot
You and the customer sign on the screen. Photos carry the date and time, so there is always something to show.
A branded PDF
Your logo, company details and both signatures in one clean PDF, made with a single tap.
Report to invoice
With the invoicing add-on, a signed report becomes an invoice with VAT, a deposit and payment terms.
Teams and equipment
Engineers see only their own jobs. An equipment register tracks each unit and its next due date.

Questions, answered.
What is Maintivo?
A job sheet and site report app for small service firms. You fill in a form on site, the customer signs on your phone, and the PDF report is ready before you leave.
Does Maintivo work with no signal?
Yes. You keep working and the report uploads by itself when the signal comes back.
Can a report become an invoice?
Yes. With the invoicing add-on, a signed report turns into an invoice with VAT, a deposit and payment terms.
Is there an Android version?
The iPhone app is on the App Store. On Android, a tablet or a computer you use the Maintivo web app in the browser, with the same account.
Does the web app sync with the iPhone app?
Yes. The same user, including the admin, signs in to either one, and everything you do on the iPhone is synced to the web app automatically, and the other way round.
Is Maintivo a custom workflow system?
Yes. It started as a custom system for the engineers at Mainteniq: we mapped the job from the first form to the final invoice and built each step to run from one phone, synced with the web app. It is now an app any small service firm can use, and we build systems like it through custom workflow automation.
Who built Maintivo?
YektaD designed and built it end to end, plus the maintivo.com website and the App Store launch.
