Nobody is "wrong" for using Excel: it's the right tool to start with, and in many companies it stays useful forever. The problem isn't Excel — it's the moment a company outgrows its reports without noticing. Here are the five signs I see most often.
1. The monthly report takes days
If someone spends the first days of the month gathering exports, pasting sheets and fixing formulas, the numbers arrive after the decisions have already been made. A report that costs days of work isn't reporting: it's data craftsmanship.
2. Three versions of the same number exist
Sales according to the sales team, to accounting and to management — three files, three figures, and every meeting starts with an argument about who is right. That's the symptom of a missing single source of truth.
3. Only one person knows how to update it
The "reports file" with 40 tabs and formulas layered over years: as long as that person is around, it works. Holidays, sickness or resignation — and the company discovers it doesn't know how its own KPIs are calculated.
4. The data runs out, the questions don't
"What if we looked at it per store? Versus last year? By time slot?" — every new question is an afternoon of work. With a real data layer, those same questions are a filter in a dashboard.
5. Errors are discovered by customers
A shifted cell reference, a partial copy-paste — and the wrong price ends up in a quote. Errors in manual spreadsheets don't warn you: they surface.
What to put underneath (without a revolution)
You don't need to "throw Excel away": you need a data layer beneath it. Data flows automatically into a centralized, clean base; on top of it sit dashboards that refresh themselves — and, for those who love it, Excel connected to live data instead of pasted copies.
That's the path described in Business analytics and Dashboards & KPIs. If two or more signs sound familiar, let's talk: the first map of sources and reports takes a few days.
