Almost every SME runs its business on Excel — and rightly so: it's flexible, everyone knows it, and it's already paid for. The right question isn't "is Excel bad?" (it isn't), but "at what point does it stop being enough?". This article answers with concrete signs, no tool evangelism.
What Excel Still Does Best
Let's start with what you should NOT migrate. Excel remains unbeatable for:
- One-off calculations and simulations — testing a pricing scenario, building a quick projection
- Small volumes with stable structure — a client list, a monthly expense tracker
- Individual work — when one person uses it and the same person maintains it
- Manual data entry — typing directly into cells is faster than any alternative
If that's your reality, staying on Excel is the right call. Migrating would be cost without return.
The 6 Signs You've Hit the Limit
- 1. The monthly report takes hours (or days) — someone copies data from several files, pastes, fixes broken formulas and rebuilds charts. Every month, again. This is the most common sign and the most expensive: see what it costs in report automation: how to save 10 hours a week.
- 2. There are several "versions of the truth" — the file sales_final_v3_FIXED.xlsx circulates by email and nobody knows which is current. Different numbers in the same meeting.
- 3. The spreadsheet freezes — tens of thousands of rows, chained VLOOKUPs, opening takes minutes. Excel was not built to be a database.
- 4. Data comes from more than one source — invoicing in one system, sales in another, marketing in a third. Crossing it all by hand is where the errors described in 5 mistakes SMEs make when analysing sales data are born.
- 5. A wrong formula has already cost money — a cell dragged badly, a forgotten filter, and a decision was made on a wrong number. With no change tracking, the error is invisible until it hurts.
- 6. More people need to see the numbers — partners, store managers, the sales team. Sharing a spreadsheet means sharing the ability to break the spreadsheet.
Two or more signs present? The migration probably pays for itself within months.
What Changes with Power BI
| Situation | In Excel | In Power BI |
|---|---|---|
| Monthly report | Hours of copy/paste | Refreshes itself on open |
| Data source | Scattered files | Direct connection to your systems |
| Volume | Freezes above ~100k rows | Millions of rows without effort |
| Sharing | Email attachment (versions diverge) | One link, always current, with permissions |
| History | Each month in a separate file | Automatic trends and comparisons |
| Cost | Included in Office | Desktop free; sharing ~€10/user/month |
And a detail that surprises many people: Power BI doesn't replace Excel — it works on top of it. Your spreadsheets can remain the data source; Power BI connects to them, cleans and presents. Migration doesn't force you to abandon anything on day one.
How to Migrate Without Trauma
- Step 1 — pick ONE pain point: the report that consumes most time (usually sales or finance) and start there. A first focused dashboard, like the one in how to create a sales dashboard in Power BI, proves the value in weeks.
- Step 2 — organise the source: standardise the source spreadsheet (one row per record, consistent columns, no merged cells). It's the invisible work that determines success.
- Step 3 — define KPIs before charts: which indicators actually matter for the decision? A dashboard with 30 charts is as useless as no spreadsheet at all.
- Step 4 — only then expand: with the first panel in real use, add other areas one by one.
What Taking the Step Costs
If you implement internally, the cost is learning time (Power BI Desktop is free, but the DAX and modelling curve is real — count on weeks until the first decent panel). If you hire it out, a professional SME dashboard typically runs €80 to €900 depending on complexity — the guide how much does a Power BI dashboard cost breaks down the ranges and what drives the price.
Conclusion: It's Not Excel OR Power BI
The "Excel or Power BI" question has a less dramatic answer than it seems: Excel for working data individually and running simulations; Power BI for consolidating, tracking and sharing the numbers that run the business. The two tools coexist in the same company — each in its role.
