In apartment buildings across Belgium, you’ll often find ista hard at work behind the scenes. They’re the ones making sure people get fair and accurate bills for heating and water. They install meters. They read them. They take care of the technical setup that lets tenants only pay for what they use. It’s a job that takes a lot of coordination, planning, and fieldwork—and it has to be done right the first time.
ista Belgium handles over 200,000 apartments and works with more than 18,000 building managers and owners. That’s a lot of places to visit, a lot of meters to install or check, and a lot of people to keep informed.
But for a long time, much of that work was being tracked the old-fashioned way: emails, spreadsheets, and printed instructions. It worked, but it was starting to slow them down.
The Problem: Too Many Moving Parts, Not Enough Structure
Every job—whether it was a new meter installation, a maintenance visit, or a meter reading—needed clear planning. Technicians had to know where to go, what type of building they were entering, which equipment to bring, and who to talk to on-site.
Sometimes that information was missing. Sometimes plans changed last-minute and it didn’t reach the technician in time. Other times, reports came back incomplete or had to be filled in later—by hand. The office team often had to follow up, double-check reports, or fix details after the job was already done.
When you’re doing this kind of work at scale, small problems like that start to add up. And they take away time from helping customers.
The Change: One Place to Plan, Work, and Follow Up
When ista started using Wello, things changed quickly.
Now, every job is created and tracked in one system. When a request comes in—say a building manager asks for an installation or meter check—it’s added to Wello with all the details: the address, the building entry info, the type of meter, any special instructions.
The technician sees this right away on their phone. No more calling the office or searching through emails. They know exactly what’s expected.
On-site, they can tick off tasks, write comments, take photos, and get the resident or manager’s signature. Everything is saved instantly. When the job’s done, the report is done too. No paperwork, no delays.
What It Felt Like for the Team
The biggest change wasn’t just faster reports or better planning—it was the feeling of control.
Technicians said they felt more prepared before going on the road. They stopped having to second-guess the job or call the office for updates.
The office team felt the pressure lift too. They weren’t chasing updates or fixing half-filled forms. Everything was logged as it happened. They could spend more time helping customers and less time fixing errors.
Even customers noticed the difference. Reports came faster. Follow-up was clearer. If someone asked for an update, the answer was there—right away.
Helping with the Big Picture
ista also works on large projects like helping buildings meet new European energy rules (like EED 2.0). These jobs involve many steps and need accurate records. Wello helped here too, making it easy to track what’s been done and what still needs to happen—without losing time or missing details.
With every visit recorded clearly and tied to the right building and client, ista could show proof of work quickly, keep audits simple, and focus on delivering better service instead of digging through files.
Final Thoughts
ista Belgium’s job is all about making energy use visible, fair, and easy to manage. Wello helped them bring that same clarity into their own daily work.
From planning visits to getting reports done, Wello gave them a better way to stay organised and respond faster—without needing to change the way they work. It just made it smoother.
Now, ista teams spend less time on the small stuff and more time doing what they do best—helping people use energy smarter.
If your team runs installations, inspections, or technical visits across many buildings or sites, Wello can help you breathe easier—just like it did for ista.
