In short: Power BI and Excel are complementary tools, not rivals. Excel remains the right choice for financial modelling, scenario planning, and individual data analysis. Power BI is the right choice when you need live dashboards connected to your ERP or CRM, consistent reports shared across teams, and reporting that does not rely on someone manually exporting and maintaining spreadsheet files. For most UK SMEs using Dynamics 365 or Business Central, both tools have a role and they work best together.

Eight signs your business has outgrown Excel for reporting
Excel is a powerful tool, but it was not designed to be the reporting layer for a growing business. These are the most common indicators that Power BI connected to your ERP data would deliver a step change in visibility.
1. The monthly report takes hours to build
Someone is spending significant time each month copying data from your accounting system or ERP into a spreadsheet before any analysis begins.
2. Multiple versions of the same report exist
Different departments or managers maintain their own copies of a KPI report, and the numbers rarely agree with each other.
3. Reports are distributed by email
Sending spreadsheet files by email creates version control problems and makes it impossible to ensure everyone is working from current data.
4. Excel slows or crashes on large datasets
Reports covering several years of transactions, or pulling from multiple data sources, cause performance problems that make analysis frustrating and unreliable.
5. You cannot control who sees what
Sharing a spreadsheet file with financial data gives everyone access to everything. Power BI row-level security allows precise control over what each user sees.
6. Dashboards are screenshots, not live data
The dashboard shared with the board or senior team is a static snapshot rather than a live view that reflects the current state of the business.
7. Reporting depends on one person
If a single individual holds the knowledge of how the reporting spreadsheet works, the business has a significant operational and continuity risk.
8. You are using Business Central or Dynamics 365
Both platforms have native Power BI connectors. If you are running these systems and still reporting primarily through exported spreadsheets, you are not using what you already own.
When to use each tool
Use Power BI when…
- You need live dashboards connected to Dynamics 365 or Business Central
- Reports need to be shared consistently across teams without version risk
- You want dashboards embedded in Microsoft Teams or SharePoint
- Datasets are too large for Excel to handle comfortably
- Different users need to see different data (row-level security)
- Senior leaders need a real-time view of operational KPIs
- You want interactive filtering and drill-through without rebuilding reports
Keep using Excel when…
- You are building financial models, budgets, or forecasts
- You need full formula flexibility (VLOOKUP, INDEX/MATCH, complex IF logic)
- You are doing one-off ad hoc analysis that does not need to be shared
- You are manipulating or cleaning raw data before loading it elsewhere
- You need what-if scenario modelling with sliders and input cells
- The output is a working document, not a published report
Power BI connected to your Business Central and Dynamics 365 data
Advantage implements Power BI for UK SMEs as part of Business Central and Dynamics 365 deployments, replacing manual spreadsheet exports with live executive dashboards, operational KPIs, and financial reporting. Finance directors get the visibility they need; operations leaders get the metrics that drive decisions. And the business stops depending on one person who knows how the spreadsheet works.

Power BI implementations are most valuable when built around actual business decisions, not data for its own sake. We design dashboards with the end user in mind from the start.
We identify the KPIs, reports, and audiences that matter most, so dashboards are built around actual business decisions, not what is easy to extract.

Frequently Asked Questions: Power BI vs Excel
Common questions from UK businesses evaluating whether to move from Excel-based reporting to Microsoft Power BI, answered honestly by Advantage, Microsoft Solutions Partner.
What is the difference between Power BI and Excel?
Excel is a general-purpose spreadsheet application suited to ad hoc analysis, financial modelling, and data manipulation. Power BI is a dedicated business intelligence platform designed for building live, interactive dashboards and reports that connect directly to operational data sources.
The two tools are complementary. Many organisations use Excel for modelling and Power BI for publishing and sharing live reports with broader teams. Microsoft designs them to work together within the Microsoft 365 ecosystem.
Is Power BI better than Excel for reporting?
For publishing live operational reports and dashboards to business users, Power BI is significantly more capable than Excel. It handles larger datasets, connects directly to ERP and CRM systems such as Dynamics 365 and Business Central, and provides controlled sharing without the risk of emailed spreadsheet files with conflicting version numbers.
Excel remains the better tool for individual analysis, financial modelling, and scenarios requiring full formula flexibility. Most businesses benefit from using both.
Can Power BI read Excel files?
Yes. Power BI connects directly to Excel workbooks stored in SharePoint or OneDrive, and can import or live-query Excel data. Excel data can also be uploaded directly into Power BI Desktop.
For organisations transitioning from Excel-based reporting, this means existing data and models can be incorporated into Power BI dashboards without starting from scratch. Over time, the goal is typically to replace manual Excel exports with live connections to source systems.
Does Power BI replace Excel?
No. Power BI and Excel serve different purposes and are designed to work together. Excel remains the right tool for financial modelling, scenario analysis, and individual data manipulation. Power BI is the right tool for publishing live dashboards, sharing consistent reports across teams, and connecting to operational data sources.
The most practical approach for most UK SMEs is to use both: Excel for building models and working with numbers, Power BI for publishing dashboards that give everyone access to consistent, current data.
Is Power BI included in Microsoft 365?
Power BI Pro is included in Microsoft 365 E5 plans and available as an add-on licence for approximately £8.40 per user per month on other Microsoft 365 plans. Power BI Desktop is free to download and use.
Many UK SMEs already have access to Power BI Pro as part of their existing Microsoft 365 licences without realising it. It is worth checking your current licence entitlements before purchasing additional tools.
What are the signs that a business has outgrown Excel for reporting?
Common signs include:
- Multiple people maintaining separate versions of the same report
- Time spent each month manually copying data from accounting or ERP systems into spreadsheets
- Reports that take hours to refresh
- Excel slowing or crashing when handling large transaction datasets
- Difficulty controlling who can see or edit sensitive financial data
- A lack of real-time visibility into operational KPIs
- Reporting that depends entirely on one individual who built the spreadsheet
These are all scenarios where Power BI connected to a live data source adds significant value.
Can Advantage help us move from Excel reporting to Power BI?
Yes. Advantage implements Power BI for UK SMEs, typically as part of a Dynamics 365 or Business Central deployment. We connect Power BI directly to your ERP and CRM data to replace manual spreadsheet exports with live dashboards, deployed to Microsoft Teams and SharePoint.
