FSM work orders and a mobile technician app

The technician finds out the job only at the office
The technician sees it on their phone, the dispatcher sees the progress.
This is not a giant ERP. Smaller contracting and field-service teams get exactly what matters in the field and in the paperwork.
Paper, spreadsheets, chat messages, folders and your invoicing tool in a single system.
The time you spend on admin today, you can spend in the field or with your family.
Every job, photo and signature in its place, still searchable years later.
Minutes instead of days: quote, work order and invoice in a single flow.
These figures are indicative: they refer to the typical tool and paper usage the system replaces, and to the time spent on administration.
“Terepbázis grew out of the daily operation of our own company. Behind every feature there is a specific situation, out in the field or in the office.”

GYURELL Kft., which develops and operates Terepbázis, is an HVAC and building services contractor. The requirements came from our own daily work: every feature from a real situation on site. This is not a customer reference: this is our own field.
The daily operation of GYURELL Kft., which the system's requirements came from.
I started out running a field service company, not as a software developer.
When I went looking for a work order system, I tried everything on the market. The ones that could do what I needed came with implementation and consulting fees a team of a few people simply cannot carry. The ones we could afford did not work the way a service company actually works.
In the end it was cheaper to learn to build software and build my own than to pay for any of the subscriptions. With plenty of dead ends and plenty of struggle, but what came out of it was exactly what I needed.
Along the way I arrived at the standard I still hold: administration cannot be a company's base cost. No company grows because someone spends the whole day sorting paperwork.
After the first maintenance round I knew we were heading the right way.
We sent out the due air-conditioning maintenance reminders. Within two days we had orders worth over one and a half million forints coming back, and more jobs grew out of those, because we went out to the customers, talked to them, and things started moving.
We did nothing new. The same customers, the same service. Until then there was simply nothing telling us in time that this was the moment to reach out to them.
That is the difference. Not that the work order looks nicer. That the system knows when the next maintenance is due, and says so before the customer calls someone else.
These figures come from the daily operation of GYURELL Kft., not from a customer reference. We operate Terepbázis ourselves, and we measured it on ourselves first.
