Microsoft Goes All-In on Copilot — and Raises the Bar for Mid-Market
In March 2026, Microsoft set a clear course at FabCon: Fabric Data Agents are now generally available and positioned as "virtual analysts." At the same time, Power BI Q&A — the existing tool for natural-language queries — will be deprecated in December 2026 and replaced by Copilot.
For companies currently using Power BI, this means: if you want to keep asking questions in natural language, you need Copilot. And Copilot requires Microsoft Fabric.
The problem: Fabric is not cheap.
What Does Power BI Copilot Actually Cost?
Copilot for Power BI requires a Microsoft Fabric capacity — at minimum F64. That's approximately EUR 5,258 per month. On top of that, you need Power BI Pro licenses (~EUR 10/user/month) or Premium Per User licensing.
For a mid-market company with 20 users, the math looks like this:
| Cost Item | Power BI + Copilot | oneAgent |
|---|---|---|
| Platform license | ~EUR 5,258/month (Fabric F64) | EUR 0 |
| User licenses (20 users) | ~EUR 200/month (Pro) | EUR 550/month |
| Monthly total | ~EUR 5,458 | EUR 550 |
| Annual total | ~EUR 65,500 | EUR 6,600 |
That's a factor of 10. For 20 users.
At 50 users, the gap widens further: the Fabric capacity costs the same, while oneAgent scales linearly — EUR 1,375/month versus over EUR 5,758.
What Power BI Copilot Does Well
To be fair: Copilot is not a bad product. Microsoft has made significant progress in recent months:
- Natural-language queries: Ask questions in English, German, or other languages and get visualizations and answers directly in Power BI.
- DAX generation (GA): Copilot writes DAX formulas for you — a genuine time-saver for complex calculations.
- Mobile app: Copilot now works in the Power BI Mobile App.
- 10,000-character input: Longer, more complex queries are supported.
- Fabric Data Agents: The new "virtual analysts" can independently explore data and build reports.
If your company is already deeply embedded in the Microsoft ecosystem — with Azure, Dynamics 365, SharePoint, and Teams as core infrastructure — then Copilot is a logical extension.
Where It Falls Short for Mid-Market Companies
But this is exactly where the challenge lies for many mid-market businesses: the prerequisites don't fit.
1. Platform Lock-In
Copilot only works within Microsoft Fabric. At FabCon 2026, Microsoft unveiled its "Unified Database" strategy — a single data platform that consolidates all Microsoft services. That sounds convenient, but it means: your data, your analytics, and your workflows are tied to one ecosystem.
Gartner warns in its latest report that a "hard reset" in self-service analytics is needed. Too many companies have locked themselves into closed platforms that cost them flexibility.
2. Cost-Benefit for the Mid-Market
Fabric F64 is designed for enterprises. A company with 50 employees pays the same platform fee as one with 5,000 — making the cost per user disproportionately high.
3. Data Sources Beyond Microsoft
Many mid-market companies work with a mix of systems: SAP, Shopware, WooCommerce, industry-specific ERPs, Google Analytics, various CRM systems. Power BI can connect to many of them — but Copilot works best when data lives in Fabric. That means: migration, transformation, additional effort.
4. No Dedicated BI Team
Setting up Fabric and Copilot requires expertise: capacity planning, data modeling in OneLake, gateway configuration, governance settings. Enterprises have BI teams for this. In mid-market companies, this often falls to the IT lead — alongside 20 other responsibilities.
The Alternative: Analytics Without Platform Lock-In
oneAgent takes a different approach. Instead of requiring a complete data platform, oneAgent connects directly to your existing systems — no migration, no Fabric, no lock-in.
What oneAgent Does Differently
- 550+ connectors: SAP, Shopware, Salesforce, Google Analytics, PostgreSQL, Excel, REST APIs — oneAgent connects to what you have. Not just Microsoft sources.
- Natural language: Questions like "Which products had the highest return rate in Q1?" work in plain English or German, no SQL or DAX required.
- Verified answers: An automatic verification layer checks every answer against your actual data. No hallucinations, no rounded estimates.
- GDPR compliant: Hosted in Frankfurt, on-premise option available. Your data never leaves your network if you don't want it to.
- No vendor lock-in: oneAgent is an independent platform. You can switch at any time, your data belongs to you.
Feature Comparison: Power BI Copilot vs. oneAgent
| Feature | Power BI Copilot | oneAgent |
|---|---|---|
| Natural-language queries | Yes | Yes |
| Supported languages | Multiple (incl. German) | German, English + more |
| Data sources | Primarily Microsoft Fabric | 550+ connectors |
| DAX/SQL generation | Yes (DAX) | Yes (SQL, automatic) |
| Answer verification | No | Yes (automatic verification layer) |
| Minimum infrastructure | Fabric F64 (~EUR 5,258/month) | None (SaaS or on-premise) |
| GDPR / On-premise | Cloud only (EU data centers available) | Frankfurt-hosted + on-premise |
| Setup time | Weeks to months (Fabric setup) | Hours to days |
| Target audience | Enterprise (1,000+ employees) | Mid-market |
| Price (20 users) | ~EUR 5,458/month | EUR 550/month |
When Power BI Copilot Is Still the Right Choice
There are scenarios where Copilot is the better option:
- You already use Microsoft Fabric and have the capacity booked anyway.
- Your company has more than 1,000 employees and a dedicated BI team.
- All your data already lives in the Microsoft world (Azure SQL, Dynamics, SharePoint).
- You need deep DAX integration features and complex Power BI reports.
In these cases, Copilot is a sensible extension of your existing stack.
When oneAgent Is the Better Choice
oneAgent is a better fit if you:
- Have diverse data sources — not just Microsoft, but SAP, Shopware, Google Analytics, and more.
- Want to get started quickly — without weeks of Fabric setup.
- Need to control costs — EUR 25/user/month instead of EUR 5,000+ in platform fees.
- Don't have a BI team to administer Fabric.
- Require GDPR compliance with European hosting.
- Want to stay flexible rather than locking into one ecosystem.
What Gartner Says
In its latest analytics report, Gartner called on the industry to rethink self-service analytics. The message: major platforms are becoming increasingly complex and expensive, while the actual task — answering business questions quickly and reliably — should be simpler.
That's exactly what oneAgent does: reduce complexity. No platform migration, no new infrastructure. Just ask questions and get reliable answers.
Conclusion: EUR 5,000 per Month Doesn't Have to Be the Answer
Power BI Copilot is a capable tool — for companies that have already invested in Microsoft Fabric. For mid-market companies that use diverse data sources and can't spend five figures per month on a BI platform, there are better options.
oneAgent offers natural-language data analytics with 550+ connectors, verified answers, and European hosting — starting at EUR 25 per user per month. No lock-in, no Fabric, no hidden platform costs.
Try free for 14 days — no credit card, no Fabric license required.
