If you run a plumbing company, a gas & electricity business, or an installations team, you know the strange arithmetic of growing. Win more work, and the admin behind that work grows faster than the team handling it. Every new job means another call to answer, another appointment to confirm, another invoice to chase. Eventually the office can’t keep pace with the vans and good jobs start slipping through the cracks.
That gap is the reason STJ Automations exists. We are a Maastricht-based company providing AI automation services to trades and property businesses across the Netherlands and Europe, from fire & security firms to home services providers and housing associations.
The problem isn’t the work, it’s everything around it
Skilled trades are facing a real labour shortage. Fewer people are entering the trades than are leaving them, which means every missed call, no-show, and unpaid invoice now costs more than it used to.
The cracks tend to show up in predictable places. A missed call after hours becomes a customer who books with someone else. An appointment without a reminder falls through and wastes a technician’s slot. An invoice sits unpaid for weeks because no one has time to follow up. A housing association can’t keep up with tenant maintenance requests, or a fire & security company misses a callback for a routine inspection. None of these are failures of skill, they are failures of bandwidth. And adding staff is slow, expensive, and harder than ever.
What we do
STJ Automations designs and builds AI agents that handle the calls, scheduling, and follow-up that slow growing teams down, so the people you already have can focus on the work itself. We work across six sectors: Gas & Electricity, Plumbing, Installers, Fire & Security, Home Services, and Housing Associations, each with its own call patterns, emergency callouts, and compliance follow-ups.
Four core agents cover most of the day-to-day admin these businesses deal with:
- After-Hours Reception: answers calls and messages when you’re closed, so an emergency callout for a gas & electricity or fire & security client never goes to voicemail.
- Daytime Reception: handles live calls and messages during the day, even when your plumbing or installation team is out on-site.
- Appointment Confirmation: sends automatic reminders and confirmations to cut down on no-shows, whether that’s a routine inspection or a housing association maintenance visit.
- Billing & Collections: follows up on unpaid invoices automatically, so cash flow doesn’t depend on memory.
When a business has a specific workflow, whether you’re an installer, a home services provider, or a housing association managing hundreds of units, we build a custom agent around it. Everything works with the systems you already use, so there is nothing to rip out and replace.
Our approach
Rather than offering a generic, self-serve product, we work closely with each client. We take the time to understand how a gas & electricity company, a plumbing business, an installer, a fire & security firm, a home services provider, or a housing association actually runs, tailor each agent accordingly, and provide ongoing support as the business grows. We work with a small number of clients so that each one receives proper attention. If administrative work is getting in the way of the work you’re actually good at, that is the problem we solve.
