A field service app for your technicians

Technicians fill in paper job sheets, photos sit on personal phones and someone in the office retypes it all for invoicing? We build you an app where technicians record the job on site — with photos and the customer's signature — and the office has it straight away.

You don't need to know which technology you need. Show us what one job looks like today, from the phone call to the invoice.

A service technician at a boiler with a service report on his phone

Sound familiar?

Paper job sheets

Illegible, crumpled, lost. And the invoice gets delayed because of them.

Photos on personal phones

Proof of the work sits in the technician's gallery between holiday photos.

Retyping in the office

Someone spends hours retyping reports into the system and fixing mistakes.

Disputes over time and materials

The customer says the technician was there for less time. Without a signature and record it is hard to prove.

What your technicians will be able to do

See their jobs

Address, contact, equipment history and what needs doing — on the phone before they arrive.

Fill in the report on site

Time, work and materials picked from lists, not typed.

Take photos and get a signature

Before and after photos and the customer's signature with a finger on the screen.

Work without signal

In a basement or on a building site, the report is saved and sent once there is signal.

Send the report to the customer

A finished report with photos goes to the customer by email right after the job.

And the office has everything

Reports ready for invoicing and an overview of jobs and technicians.

Website or mobile app? We'll work that out

Technicians work on phones or tablets, the office on computers. The app therefore usually has two parts on the same data.

Whether the mobile part goes into the App Store and Google Play or a web version is enough, we recommend based on how and where your people work.

When a ready-made tool is enough

There are off-the-shelf apps for service reports and field service management, and they can be enough for smaller teams. A custom app makes sense when:

  • you have your own forms, inspections or protocols a ready-made app can't do,
  • you want reports connected to your own invoicing, stock or accounting,
  • you have a larger team and pay a licence per technician,
  • you want an app that fits your people — otherwise they won't use it.

Frequently asked questions

Will technicians who dislike phones manage?

We design it so a report takes less time than paper: big buttons, picking from lists, minimal typing. Your people try it before launch.

Does it work without signal?

Yes. The report is saved on the phone and sent once signal returns.

Can it connect to invoicing?

Usually yes — a report can directly create the basis for an invoice. It depends on the system you use; we check it during the design.

Can report processing be automated further?

Yes. Checking reports, copying them into other systems or reporting can be automated by our sister brand Grow-AI.

How long does it take?

We work in two-week cycles and you try every finished part straight away. A simpler first version can reach people within a matter of months. You get an exact timeline together with the price after the first conversation.
