For electrical, HVAC, roofing and plumbing subcontractors

The wrong engineer can't be sent to the job.

Tickets, distance and who's actually free — settled before the job leaves the office. Your crew sees it in an app with your name on it.

  • Nothing from an app store
  • A PIN, not a password
  • Your name and colours on it

The job that cannot go to the wrong man

A ticket lapsed in March and nobody in the office knows, because knowing is one person remembering a date on a card. Here is what that looks like when the office is not the thing remembering.

Worked example · one emergency, four engineers

16:42No heat — commercial boiler downRiverside House, floors 1–4Gas ticket required

2 of 4 can take it · 2 were never offered it

  • Ollie NashElectricalTesting & inspection1.2 kmNot offered — no gas ticket
  • Marek SobolGas ticketCommercial boiler4.2 km
  • Dana WhelanPlumbingCommercial boiler3.1 kmNot offered — no gas ticket
  • Ruth ElleryGas ticketCommercial boiler18.6 km

Send it to whichever of the two you would have rung.

Ollie and Dana were not warned off this job and did not see it greyed out. It was never on their phone. That is the difference between a reminder and a rule — and it is the one thing on this page you can check for yourself in ninety seconds, on a whole shift. Figures here are an example, not live data.

Four things that happen in a normal week

None of them is a software problem until the day it costs you a contract.

  1. 07:10

    The ticket that lapsed in March

    The job goes out to whoever is free. Whoever is free is not certified for it. Nobody in the office knew, because knowing is one person remembering a date on a card they last saw at an induction.

    The version of this that works is not a reminder. It is that the job is never offered to him in the first place — not flagged, not warned about, not there. He sees the four jobs he can do and none of the ones he cannot.

  2. 10:40

    The emergency, while everyone is already out

    Two questions decide it: who can do this, and who is nearest. Answering them means ringing round, and ringing round takes the twenty minutes that made it an emergency.

    Both are answerable the second it lands, from where each van actually is right now — not from where it started this morning.

  3. 13:00

    The toolbox talk nobody can find the sheet for

    You ran it. Everyone was there. The sheet is in a van, in a folder, in the rain, or it is in the office and three names are missing.

    The same talk goes out as a job. Each person opens it, reads it, signs it off. The record is what he tapped and when, and it does not live in a van.

  4. 16:30

    The job that finished on Tuesday and got invoiced in April

    Nobody is hiding the paperwork. It is in a pocket, then a dashboard, then a pile, and by the time it reaches accounts the client has forgotten the visit.

    When finishing the job is itself the paperwork, the gap closes on its own.

What your crew actually gets

An app with your name and your colours on it. They add it from a link — the way you'd save a website to the home screen — and it is there next to everything else on the phone.

  • Nothing from an app storeNo download, no company email, no company phone. A link or a code on the wall, once. On an iPhone it is the Share button, and the app tells them so.
  • No password to forgetThey set a PIN the first time, from a link you send. They can change it themselves. You are not the help desk for it.
  • On shift is their decisionNobody is reachable for work because a record exists. They say they are on, and they can say they are off — so an unanswered job is a real signal instead of a guess.
  • Today's jobs, and what each one needsWhat it is, where, what it needs, anything you want them to read first. They take it, do it, and mark it done.

What it doesn't do

Written down here rather than found out in month two.

  • It does not work without a signal.If your crews are regularly somewhere with no bars — plant rooms, deep basements, remote sites — say so now and we will tell you straight whether this is worth your time. We would rather lose the sale than the second month.
  • Your crew cannot attach photos to a job yet.What you get is a timestamped record of who marked what done and when. Photo attachments exist on the office side today, not the crew's. If site photos are the whole reason you are looking, this is not ready for you.
  • We do not hold SOC 2 or ISO 27001.Your data sits in the EU, there is a data-processing agreement you can read without emailing anyone, and the part that does the work is public and free — if our price ever stops working for you, your own IT can run it and you keep everything.
  • There are no customer logos on this page.We have not put words in anyone else's mouth. When someone real is happy to be named, they will be named here.

The cheapest way to find out

There is a 90-second thing on this site where you dispatch a shift yourself and then watch the same shift get dispatched properly. Most people lose it on one job, and it is always the same job. That is the whole argument, and it takes less time than reading this page did.

What you get

  • Ten talks — working at height, isolation, manual handling, hot works, asbestos awareness, and five more
  • Each one written to be read on a phone in about four minutes
  • A sign-off sheet that works on paper, for the sites that still want paper
  • A one-page site induction you can hand a new starter

It lands in your inbox in about a minute. Nobody rings you unless you ask us to.
