Most companies today hold more data than ever, yet that data usually lives scattered across disconnected systems: part of it in the ERP, part in Excel spreadsheets, part in the webshop, and part in marketing and sales tools. The problem is rarely a lack of data, but the inability to extract a meaningful picture of the business from it quickly and reliably. This is where Power BI, Microsoft's business analytics platform, makes the difference, as it connects data from different sources, turns it into visual reports and dashboards, and allows management to make decisions based on current figures rather than estimates or outdated spreadsheets maintained by hand.
What Power BI is
Power BI is a business analytics and data visualisation platform developed by Microsoft. Its core role is to bring data from various sources into one place, process it, and present it as interactive reports and dashboards that users can view on a computer, in a browser, or on a mobile device. Unlike static Excel spreadsheets that show the situation at the moment they were created, Power BI reports are connected to their data sources and refresh automatically, which means the figure on screen always reflects the real state of affairs. As part of the Microsoft ecosystem, the tool connects naturally with the software companies already use, such as Excel, the Microsoft 365 environment, and SQL databases.
Which sources Power BI pulls data from
The strength of Power BI lies in the fact that it is not limited to a single data source but connects several systems at once and presents them through a unified view. The most common sources companies work with are the following:
| Data source | Typical content |
|---|---|
| ERP system | Finance, inventory, procurement, sales |
| Excel and CSV | Manually maintained records and plans |
| Webshop | Orders, revenue, customer behaviour |
| CRM | Sales funnel, contacts, activities |
| SQL databases | Operational data from internal applications |
| Google Analytics | Traffic and sources of website visits |
Power BI does not merely pull these sources in but also links them together, so it is possible, for example, to see in a single report how much revenue a particular marketing campaign generated and how that affected inventory and procurement.
The difference between reports and dashboards
Power BI distinguishes between reports and dashboards, even though the terms are often used interchangeably in everyday speech. A report is a detailed document that can span several pages and allows deeper analysis of a specific topic, such as sales by product, region, or time period. A dashboard is a condensed overview that brings the most important indicators from one or more reports onto a single screen, serving as a quick daily control panel for management. Both are interactive, meaning a user can click on an individual element and immediately see how the rest of the data changes, without having to build a new table or chart.
Who benefits most from Power BI
Power BI is particularly valuable for companies that have outgrown the stage where Excel was sufficient but do not yet have a complex business intelligence system in place. Companies that make daily decisions based on sales, financial, or operational data gain the most, as the tool shortens the time from question to answer. The value is equally pronounced in organisations where several people need access to the same data, because instead of everyone keeping their own version of a spreadsheet, they all look at a single source of truth that refreshes automatically. For executives who want insight into the business without waiting for monthly reports, Power BI offers a way to see where the company stands at any moment.
How Power BI is introduced into a business
Introducing Power BI is not a matter of installing a tool but of thoughtfully setting up the entire data flow from source to report. The first step is an analysis that establishes which decisions the reports need to support and which data is required for that, because a good dashboard starts from a business question rather than from the available data. This is followed by connecting the sources and preparing the data, which is often the most demanding part, as data from different systems rarely arrives in the same format and needs to be aligned. Only then are the reports and dashboards built, and the entire process concludes with setting up automatic refresh and training the users who will work with the reports daily.

Frequently asked questions
Do we need a dedicated server for Power BI?
Not necessarily. Power BI offers a cloud version that requires no infrastructure of your own, while an on-premises option is available for specific cases. The choice depends on your security requirements and how the company wants to store its data.
Can Power BI connect to our existing ERP?
Yes. Power BI connects to most ERP systems, either directly or through a database or intermediate layer. Before the project begins, we check how the specific system exposes its data.
Do users need technical knowledge to work with the reports?
No. Finished reports and dashboards are designed so that end users can view and filter them without technical knowledge. Technical expertise is only required during setup, which Prolink handles.
How often is the data refreshed?
Depending on the source and configuration, data can refresh at set intervals or close to real time. The frequency is defined according to business needs during setup.
