Twenty-four modules, one system

One system, no integrations to babysit

From enquiry to invoice in the same place. The same client, the same project and the same amounts everywhere. Nobody retypes anything. Nothing drifts apart.

All modules

Every invoice line points back to a signed job sheet

Date, engineer, hours, what was done and who signed. When a client calls about a line, that call takes ten seconds instead of an afternoon.

How that works

The job sheet is signed where the work is

Hours, materials, photos, signature and variations on the engineer’s phone. With no signal too. In a crawl space or on a roof that is the normal state of affairs.

Out on site

Capacity is the first question, not the last

Your turnover is capped by your capacity, not by demand. Which week is full, and can we still take this job on. That question sits up front, not in a module off to one side.

Who it is for

Who this was built for

For building, installation and maintenance companies of five to seventy-five staff, in the Netherlands and Belgium. Too big now for spreadsheets and email, too small for a system that comes with a consultant.

Installation and building servicesHeating and plumbing · electrical · ventilation · cooling and climate · heat pumps · solar and batteries · data and security
Many small job sheets in a day, maintenance contracts running underneath and breakdowns coming in between. What counts here is that the engineer finishes the job sheet on site and that whatever is filled in lands on the project straight away.
Contractors and buildersNew build · conversion · refurbishment · maintenance contracting
Working in phases, with interim invoices, variations and a progress statement. Retention and the G-account belong here as routine, not as an exception. The margin leaks halfway through. That is where you need to see it.
Roofing, façades and insulationRoofers · dormers · window frames and façade elements · glazing and solar shading · insulation
Crews somewhere different every day, a lot of material per job sheet, lead times that drive the schedule, and a handover where a photo is the proof.
Fit-out and finishingPlasterers · floor layers · carpentry and interior fit-out · painters and property maintenance · tilers
Plenty of hours and little material in a job, a schedule that shifts on the day because the trade before you overran, and variations agreed on the floor. In property maintenance you add long-term planning and void works per home.
Service and maintenanceMaintenance contracts · call-out service · fire safety and inspections · doors and access · drainage and pipework
Service visits that have to be on time, response times you are tied to, and statutory inspections flagged separately from the rest. The most untapped work sits here, in the equipment you already look after.

Trade not on the list?

Any technical company with people out in the field and an invoice it has to be able to explain fits here. Even if your trade is not on the list. If you are not sure, tell us in the conversation how your work runs. If it does not fit, we will say so.

By role: what is on the screen

It carries your name, not ours

Platrom is fully white-label. Your logo, your colours and your typeface are on every screen your people work in. And on every document that goes out. Your client sees your quote and your invoice. Not a software vendor’s.

The colours come out of your logo
You upload your logo and the system proposes the colours. It does not ask for hex codes, because almost nobody knows them. If your colour sits below the legibility threshold, it is nudged up. A button whose text cannot be read is not branding.
On every document
Quote, invoice, job sheet and reminder come out of a template you build yourself from blocks, with your logo and your colours. A client who prescribes their own layout gets a template of their own.
At your own address
Your people sign in at yourcompany.platrom.nl, with a certificate in that name. That is not cosmetic. It is the reason a user from one company never ends up in another company’s environment by accident.

One week, one thread

This is the same job, touched five times by five different people. Nobody retypes anything, and at the end everyone knows where the line on the invoice came from.

  1. Tue 08:12 · Office

    The enquiry comes in

    An email from a housing association lands in the work queue, sorted by how long it has been waiting rather than when it arrived. The system has already read it: this is a breakdown, it is urgent, and the next step is shown beside it. Calling is one click.

  2. Tue 11:40 · Estimator

    The quote goes out

    The estimate turns into a quote with sections, provisional sums and optional items. The client signs it online. On approval the work is waiting as a job, with the budget that sat underneath it.

  3. Wed 06:55 · Site manager

    The work is dispatched

    On the schedule the work order moves to Thursday, to two engineers who have room that day. They see it on their phone, with the site, the equipment, the history and how to get in.

  4. Thu 16:41 · Engineer

    The job sheet is signed

    On the roof, with no signal. Hours, materials, photos and the client’s signature. The variation agreed on the spot is signed for as well. The moment the phone finds a bar it is all in.

  5. Fri 09:03 · Accounts

    The invoice goes out

    The line on the invoice points back to that job sheet: date, engineer, hours, what was done and who signed. When the client calls about that line, the conversation is over in ten seconds.

The planning board answers the question that has come to decide this trade. Can we still take this job on? Capacity caps turnover, not demand.

The job sheet is signed where the work happens

Hours, materials, photos, the client’s signature and the variations you agree on the spot. On the phone the engineer is already holding.

With no signal
In a crawl space, behind a thick wall, on a roof out in open country. Everything keeps working and goes across on its own the moment there is a bar again. Offline is not the exception here but the normal state of affairs.
Variations that are signed for
The conversation you would otherwise have three weeks later with a client who remembers none of it. Now it is there in black and white, with a signature and a time.
No Friday afternoon
No paper job book landing on a desk half filled in, and no evening spent retyping. What is signed is in.

What is in it

No separate programs trying to keep up with each other through an integration. One system, in which the same client, the same project and the same amounts are the same everywhere.

What it costs, with no conversation first

Three plans that differ in which modules are in them, not in how much of the same thing you are allowed. Three users are in every plan. Above that a user costs €33 per month.

The whole chain in one system

This is where the first companies will be

Platrom is going live now. The first environments are being set up this month. Their names will appear here once they are happy with that and not a day sooner. Until then you get to see the system itself. Everything on this site can be walked through in a demo on your own work.

Come and look in a demo

Half an hour, on your own work

No slides. We take one of your projects. A breakdown, a roof refurbishment or a maintenance contract. We walk it through the system, from enquiry to invoice line.

  • You are talking to someone who built the system, not an account manager with a script.
  • Your request lands in a work queue on our side, with a clock on it.
  • No newsletter and nothing sold on.
We confirm the time by email. Nothing is put in a calendar automatically.

We use your details only to reply. No newsletter and nothing sold on. See our privacy statement.
