Excel Dashboard vs Power BI Finance Teams: Why Excel Wins
The Excel dashboard vs Power BI finance debate, from a six-figure portal my team skipped: why speed to iterate wins, plus a 3-question tool test.
Last week, I spent 4 hours rebuilding a dashboard from scratch. In Excel. Again. That’s where I keep landing in the Excel dashboard vs Power BI finance debate.
We have a portal. It cost six figures. It has 47 features we requested, a dedicated support team, and a roadmap full of improvements.
My team rebuilt the dashboard in Excel anyway.
Not because they’re stubborn. Because Excel is faster to iterate.
The Excel Dashboard vs Power BI Finance Debate I Keep Having
A colleague pushed back on this. “We should be using the portal more. That’s what it’s built for.”
He’s right. In theory.
In practice, here’s what happens:
The CFO asks: “What if we cut Program A and doubled Program B?”
Option 1 (Portal): Submit a request. Wait for the data team to adjust parameters. Review the new view. Request modifications. Wait again. Get the answer in 2 weeks.
Option 2 (Excel): Open the file. Change two assumptions. See three scenarios in 20 minutes. Done.
The portal has better features. Better security. Better audit trails. Better everything.
But Excel has something the portal doesn’t:
Speed to iterate.
The Philosophy I’ve Landed On
I have a high tolerance for iteration. But I have zero tolerance for tools that slow us down.
Here’s the distinction:
Good slow: Thorough due diligence on a major decision. Multiple reviews on a board presentation. Careful validation of source data.
Bad slow: Waiting 2 weeks to see a what-if scenario. Filing support tickets for dashboard modifications. Having a “roadmap” for features you need yesterday.
The portal fails because it optimizes for the wrong thing.
It optimizes for capability. What it can do.
Excel optimizes for iteration. What you can change right now.
Enterprise tools are built to handle everything. Spreadsheets are built to answer questions.
Guess which one survives.
The 3-Question Test Before Any Enterprise Tool
Before we adopt any new tool, I ask three questions:
- Can I model a scenario in under 30 minutes? If the answer is “submit a request” or “schedule a training,” the tool will fail. Not immediately. Eventually. When the CFO needs an answer fast and the tool can’t keep up.
- Can my team modify it without IT? If every change requires a ticket, the tool becomes a bottleneck. Finance moves too fast for approval queues.
- Will we still need Excel anyway? Be honest. If the answer is yes, you’re buying a tool and maintaining two systems. That’s not efficiency. That’s overhead.
Most enterprise tools fail question 3. We still end up in Excel for the “quick analysis” that becomes the actual decision.
The Messy Truth
I’m not anti-portal. I’m anti-slow.
The portal has its place:
- Historical reporting that doesn’t change
- Compliance documentation
- Audit trails for recurring reports
But for decision support? For scenario planning? For the question the CEO asks at 4pm on a Thursday?
Excel wins. Every time.
The cockroach of enterprise software. Nuclear winter couldn’t kill it.
Look at your last 10 “quick analyses.” Where did you actually do them?
If the answer is Excel (or Google Sheets, same thing), ask yourself: Why are we maintaining a portal we don’t use for the work that matters?
Maybe the portal’s fine for what it does. Maybe it’s time to stop pretending it does everything.
