A slow or unreliable report is almost never a problem with the report itself. The issue lies in the underlying model: the relationships between tables, how data is loaded, and decisions that are no longer visible to anyone. We support your Power BI environment with the modeling discipline we have developed over twenty years of data projects.
A report that will not load, figures that do not add up, or a slow dashboard: that is what a user reports. But the cause rarely lies in the visual. A refresh may fail because a source has changed. A relationship between tables may be set up incorrectly, causing a total to be wrong. Or a model may be structured in a way that makes every interaction require too much processing. Those are the things we look at first.
We handle these reports and resolve the underlying cause. A failed refresh, usually due to a changed source, a timeout, or a scheduling conflict. A data connection that needs to be reauthorized. And performance issues, which are often solved not with a faster machine but with a better model: fewer unnecessary relationships, smarter calculations, and a structure that does not recalculate the entire model with every click.
The routine work continues as well: adding users, adjusting roles and permissions, arranging access, and making the smaller visual changes that inevitably come up. We take care of those too.
A Power BI environment that no one manages gradually becomes cluttered. Reports pile up, refreshes start causing problems, permissions become outdated, and no one knows which dashboard is the source of truth anymore. That is why we review your environment on a fixed schedule. We perform these checks using Power BI’s own monitoring dashboards and usage metrics, and via the REST API where that is more practical.
When everything is running smoothly, most of this goes unnoticed—and that is exactly the point. If you keep an environment properly maintained, you do not have to figure it all out again every year.
Most Power BI problems we solve do not originate in the reporting layer, but in the underlying model. A dashboard is only as reliable and fast as the data model it runs on, and that model is often where things go wrong when delivery is rushed.
Here is an example that occurs more often than you might think: in Power BI, you can create multiple relationships between two tables, but only one can be active. If you are not aware of that, you can end up with totals that are correct in one place but not in another, without receiving an error message. You only spot issues like that when you know where to look.
That perspective does not come from Power BI alone. We know the platform itself well, from DAX to the reporting layer and the service, but the reason we find difficult problems quickly is that we have been applying the underlying data discipline for twenty years. Data modeling was not invented with Power BI; it is a field we have learned across multiple platforms. Our consultants are PL-300 certified, and that knowledge is built on a foundation of twenty years of data projects. Read more about our Power BI work on our Power BI Consulting page.
Do you have a Power BI environment that someone else set up? We start with an assessment. We examine the data models behind the reports, the refreshes and connections, the permissions structure, and how reports and workspaces are organized, so both sides know exactly what we are taking over.
This almost always produces a list of items that need attention. We address anything urgent, and include the rest in a plan. Often, the biggest gains are not in the reports you see, but in the underlying models: improving their design can resolve several issues at once.
Power BI support is available through the same support packages as our other platforms: Starter, Booster, and Premium, with fixed response times and a monthly allocation of hours. Starting at €950 per month. You can find the full comparison, including add-ons, on our Support & Management page.
Not sure which package is right for you? We will look at the number of reports and users, the complexity of your models, and which tasks you already handle yourself.
We’ll be happy to take a look with you and discuss what stands out, how urgent it is, and what the right next step would be.
Yes, and we start by finding the real cause. Slowness is rarely caused by the visual itself. It is usually the underlying model: too many or incorrect relationships, calculations that run again with every interaction, or a dataset that has grown beyond what the design can handle. We address the root cause rather than applying a temporary fix.
We investigate where the error originates. Sometimes it is in the source, sometimes in the refresh, and often in the model—for example, an incorrectly configured relationship between tables that causes a total to be correct in one place but not in another. This is exactly the kind of problem that does not generate an error message and requires a thorough understanding of the model.
Yes. DAX is powerful, but it is also easy to misuse. A measure may be correct on paper but grind to a halt with large datasets, or a calculation may produce slightly different figures than expected because of the context in which it runs. We examine what the calculation does, why it behaves that way, and whether there is a more efficient approach. The solution is often not in the measure itself, but in the underlying model.
Yes. Microsoft regularly removes visuals from Power BI, which can suddenly prevent reports that rely on them from working properly. We identify which visuals are being phased out and replace them in time, before users encounter a blank area in a report.
Yes. In many organizations, the number of reports and workspaces grows faster than anyone can keep track of. Eventually, no one knows which dashboard shows the correct figures. We map out what exists, what is actually being used, and what can be removed, then help you restore an environment where it is clear which information is authoritative.
Two things. First, continuity: if your administrator is unavailable or leaves, management of the environment continues. Second, another perspective on difficult cases, such as a modeling issue your team cannot resolve or a report that remains slow despite everything you have tried. Your own team stays in control, while we handle peaks in demand and provide expert input when needed.
Yes. We start with an assessment of the models, refreshes, permissions, and the organization of reports and workspaces. Afterward, you will know what is in place, what needs attention, and in what order it should be addressed.
Both. Power BI has become part of Microsoft Fabric, so in practice they overlap. If your question mainly concerns reports, datasets, and the model, you are in the right place. If it is more about the broader data platform, pipelines, and capacity, our Microsoft Fabric support page is a better place to start.
Whether a report has stopped working or you want to know if your environment is still configured correctly, Barry and Eric will be happy to discuss it with you. Send us an email, call us, or schedule an appointment directly at a time that suits you.
