Field technicians and service teams when ready-made software is not enough

Ready-made or custom software to manage technicians and service calls?

Ready-made, for the part that is the same in every company: the schedule of service calls, the technician's app, the job report with photos and the customer's signature, the report sent automatically. Custom, for the piece that earns you money and that products do not follow, and often you only need to build that piece, next to the product.

On 31 October 2026 we put to Google, its AI Mode, ChatGPT and Perplexity, in Italian and in English, the case of an installation and maintenance company with 25 technicians and 15 vans that schedules by phone and in a spreadsheet, while the office retypes paper job reports to invoice. Every answer says to buy a ready-made product. Google's AI Mode puts it this way: building everything from scratch makes no economic sense unless your procedures are unique in the world.

We agree on the starting point, even though custom software is our job. If a ready-made product is enough for you, we tell you before the quote, even when it is a product we do not make. But almost all the answers stop there. Few say what to do when the product covers half of the work, and none mentions the rules on GPS in the vans. This guide starts from what is missing.

What should it do, from the call to the invoice?

It should follow the service call from the moment the customer phones to the moment they pay, without anyone retyping a single piece of data. The schedule alone is not enough: as ChatGPT wrote, your problem starts when the phone rings.

Of the 124 pages we read, from Google results and the sources of the AI answers, 70 mention the job report and the customer's signature together, 55 working without a connection, 44 planned maintenance or contracts. These are the minimum features, and serious products have them. The difference lies in the last row: if hours and materials do not reach the management system on their own, you have only moved the paper onto a screen.

A digital job report is worth having if what the technician writes at the customer's site reaches the invoice without anyone retyping it. In the systems we build data passes to the accounting system without double entry, and if the network drops, events are queued and resynchronised when it comes back.

How much does ready-made field service software cost?

From 5 to 91 € per user a month, excluding VAT, on the public price lists we read on 31 October 2026. For 25 technicians that is 1,500 to 27,300 € a year, plus the office users where the price list counts them.

The price lists are those of D-TEC, Nomadia, Synchroteam and Microsoft, all in Italian. It is not a ranking: the price says little until you know what it covers. Between an app costing a few euros and a platform at 85-91 € what changes is automatic route planning, contracts, stock and the links with other systems. Before comparing two prices, ask what activation, the link to your management system and the office users cost.

And how much does custom software cost?

It depends on what you build: only the missing piece or the whole system. The figures you find online help little, because none has a source that measures them and they change with the language of the question: Google's AI Mode itself, in English, multiplies by four or five the figure it gives in Italian.

An MVP is the first version that solves a single problem, but solves it in production: for example maintenance contracts with their deadlines, linked to the management system, next to the job report app you already use. A complete system, with a technicians' app that also works offline, scheduling, contracts, van stock and the link to the management system, costs more: the figure comes out of the analysis, within a range with the maximum written into the contract, as the guide on how much custom software costs explains.

We estimate maintenance on the work the software really requires, not as a percentage of the development cost, with hosting separate, as the guide on maintenance explains. On software we develop for you there is no license fee, so the cost does not grow with every technician you hire.

When is ready-made software not enough?

When the product covers the schedule and the job report, but not the work that earns you money. There are five signs, and each can be checked in a demo.

The most common case is the second one we put to the AI answers: a company with 12 technicians on boilers and air conditioners that already has a job report app, but not planned maintenance contracts, inspection deadlines and spare parts in the van, and no link to the management system. Google's AI Overview and AI Mode and Perplexity answer to switch to a sector app. ChatGPT warns that simply changing the job report app risks moving the problem without solving it, and suggests keeping the management system and putting next to it a system for contracts, deadlines and spare parts. Of the 124 pages we read, only 8 talk about stock in the van.

Often you do not need to redo everything: the job report app stays, and you build the missing piece, linked to the management system. The two roads can be combined, as the guide on custom or off-the-shelf explains. For people who work in the field we have already built these pieces:

Each project has its case study: managing technical interventions, resource and project planning and telecare monitoring and surveillance.

What does Italian law ask of those who service boilers and air conditioners?

Two obligations with a deadline, which the software must know because, if you miss them, you are the one who answers for it. After the energy efficiency inspection of a heating system, the technician fills in and signs an inspection report; one copy goes to the person responsible for the system, who attaches it to the system logbook, and one copy goes to the Region or autonomous Province at the intervals set by the decree (Presidential Decree 74/2013, article 8, in Italian). On equipment containing fluorinated gases, installations, leak checks, maintenance, repairs and decommissioning are reported to the F-gas database within thirty days of the work (Presidential Decree 146/2018, article 16, in Italian).

On the boiler question, Google's AI Overview and AI Mode and Perplexity mention these obligations, and use them as an argument for the ready-made product: the vendor updates them for you. That is true, and a good reason to look at sector apps first. But it only holds if the app also follows the rest of your work: if contracts live in a separate spreadsheet, you miss the deadline anyway.

An obligation with a deadline belongs in the software as a rule, not in the memory of whoever schedules the work. Heating system registers change from region to region, and as with the whole guide this is a technical contribution, not legal advice.

Can you put GPS on technicians' vans in Italy?

Yes, but switching on the service is not enough. Under the Italian Workers' Statute, a tool that can lead to remote monitoring of workers may be used only for organisational and production needs, for workplace safety and to protect company assets, and only after an agreement with the trade union representatives or, failing that, with the authorisation of the Labour Inspectorate (article 4, in Italian). The Inspectorate has a dedicated form to apply for authorisation of satellite tracking systems.

GPS appears as a feature in 47 of the 124 pages we read and in 6 of 22 AI answers. No page and no answer mentions the Workers' Statute or the union agreement. If the job report app also records where the technician is during the day, that feature must be assessed separately.

Before switching on GPS, ask your employment consultant, not the software vendor: the vendor sells you the feature, the responsibility stays with you.

Where do you start?

From the point where a piece of data is written twice today.

1. For a week, count the job reports the office retypes and how long it takes, and the calls made only to find out where a technician is.
2. List the deadlines you cannot miss: periodic inspections, reports, F-gas submissions, contract renewals.
3. Try two or three products with a demo on your real cases. For companies working on boilers and air conditioners, Perplexity suggested three: a boiler with its annual inspection, an air conditioner with F-gas and a van with 30-50 spare part codes. Above all, check how hours and materials pass to your management system.
4. Start with a few technicians: Perplexity suggested 5 technicians and one coordinator for 30 days. Measure a few things: job reports reaching the invoice without being retyped, service calls closed the same day, deadlines met.
5. If a product covers everything, take it. If it covers part of it, build only the missing part, next to it.

You start from the piece that costs the most hours today, not from the list of every feature. Starting small is often the road we recommend: a module in production tells you more than a specification.

An example: 25 technicians and 15 vans

An installation and maintenance company with 25 technicians and 15 vans schedules by phone and in a spreadsheet; job reports are on paper, and the office retypes them to invoice. It is the case we put to Google and the AI assistants. The figures below are made up, to be replaced with yours.

The first step is the count. With 60 service calls a day and 4 minutes to retype each job report, the office spends 4 hours a day retyping, before even looking for a lost or illegible report.

The second is the product. For 25 technicians an app at 5 € a month costs 1,500 € a year, a platform at 91 € costs 27,300. The cheap app handles the signed job report well, but maintenance contracts stay in a spreadsheet, and the spare parts in the 15 vans are counted at the end of the month.

The third is the missing piece, built next to the app: contracts and deadlines that generate service calls, the stock of each van drawn down from the job reports, and hours and materials passing to the accounting system. To start, the first is enough, contracts and deadlines linked to the management system. It is an MVP: with us an MVP starts from 10,000 € and takes 6-8 weeks, and we estimate maintenance of a management system with integrations at about 5,000 € a year. After two months of use you decide whether to add the van stock.
