oneAgent and Power BI Copilot both enable natural-language data analysis, but they differ fundamentally in cost and target audience. Power BI Copilot requires Microsoft Fabric (starting at approx. EUR 4,900/month), while oneAgent starts at EUR 25 per user per month. For mid-market companies, oneAgent is up to ten times more affordable — with comparable functionality and GDPR-compliant hosting in Frankfurt, Germany.
What Does Power BI Copilot Actually Cost?
The licensing costs for Power BI Copilot are not immediately obvious. Copilot is not a standalone product — it is a feature within Microsoft Fabric. And Fabric has a significant minimum price.
Prerequisites for Power BI Copilot
- Microsoft Fabric F64 capacity: approx. EUR 4,900/month — this is the entry barrier
- Power BI Pro licenses: approx. EUR 10/user/month (or PPU at approx. EUR 20)
- Microsoft 365 licenses: required for Fabric, often already in place
Cost Comparison: 20 Users
| Cost Item | Power BI + Copilot | oneAgent |
|---|---|---|
| Platform license | ~EUR 4,900/month (Fabric F64) | EUR 0 |
| User licenses (20 users) | ~EUR 200/month (Pro) | EUR 500/month |
| Monthly total | ~EUR 5,100 | EUR 500 |
| Annual total | ~EUR 61,200 | EUR 6,000 |
| Onboarding / setup | Variable (consulting) | From EUR 1,500 (one-time) |
Factor 10. For the same core function: employees ask questions about their business data and get answers.
Cost Comparison: 50 Users
| Cost Item | Power BI + Copilot | oneAgent |
|---|---|---|
| Platform license | ~EUR 4,900/month | EUR 0 |
| User licenses (50 users) | ~EUR 500/month | EUR 1,250/month |
| Monthly total | ~EUR 5,400 | EUR 1,250 |
| Annual total | ~EUR 64,800 | EUR 15,000 |
The Fabric capacity is a fixed-cost block. With oneAgent, costs scale linearly with user count — no minimum fee.
Feature Comparison: oneAgent vs. Power BI Copilot
| Feature | oneAgent | Power BI Copilot |
|---|---|---|
| Natural-language queries | Yes — chat interface for all employees | Yes — within Power BI |
| Supported languages | German, English, more | German, English, more |
| Data sources / connectors | 550+ (Shopware, SAP, ERP, CRM, etc.) | Power BI data models (Fabric/OneLake) |
| Connector setup | Pre-configured, plug-and-play | Requires Dataflows and Semantic Models |
| AI architecture | Deterministic AI layer — no hallucinations | LLM-based (GPT-4) — probabilistic |
| DAX generation | Not needed (direct queries) | Yes — Copilot generates DAX formulas |
| Report creation | Automatic visualizations | Yes — creates Power BI reports |
| Fabric Data Agents | Not applicable | Yes (GA since March 2026) |
| GDPR-compliant | Yes — hosted in Frankfurt, on-premise option | Depends on Fabric region and configuration |
| On-premise option | Yes | No (cloud-only) |
| Minimum cost/month | EUR 25 (1 user) | ~EUR 4,910 (Fabric F64 + 1 Pro license) |
| Target audience | Mid-market | Enterprise, Microsoft ecosystem |

| Vendor lock-in | Data-source agnostic | Microsoft ecosystem |
Where Is Power BI Copilot the Better Choice?
We believe in honest comparisons. There are scenarios where Power BI Copilot is the right decision.
1. You Already Pay for Microsoft Fabric
If your organization already runs a Fabric capacity — for Data Engineering, Data Science, or Real-Time Analytics workloads — then Copilot is a sensible add-on. The base cost is already covered, and Copilot leverages your existing infrastructure.
2. Your BI Team Lives in Power BI
If your analysts work in Power BI daily, maintain DAX models, and build complex reports, Copilot is a productive extension. It generates DAX formulas, suggests visualizations, and accelerates the workflow of experienced Power BI users.
3. You Need Fabric Data Agents
Since March 2026, Fabric Data Agents are generally available. These "virtual analysts" can automate complex analysis pipelines — a capability that exists at this depth only within the Microsoft ecosystem.
4. Enterprise with 1,000+ Users
For large organizations with existing Microsoft licensing, the Fabric costs per user become manageable. At 1,000 users, the EUR 4,900 Fabric capacity adds only ~EUR 5 per user.
Where Is oneAgent the Better Choice?
1. Cost Matters
For mid-market companies with 20 to 200 users, the cost difference is not marginal — it is fundamental. EUR 6,000 vs. EUR 61,200 per year for 20 users. That is budget you can invest elsewhere.
2. Your Employees Are Not BI Experts
oneAgent is built for business departments: sales, procurement, management, controlling. These people want answers, not DAX formulas. The chat interface requires no training — you ask a question, you get an answer.
3. You Use Diverse Data Sources
With over 550 native connectors, oneAgent connects your Shopware data with your SAP, your CRM, and your accounting system — without building a centralized data model in Fabric first.
4. Deterministic Results Are Business-Critical
The deterministic AI layer in oneAgent guarantees correct results. No "the AI miscalculated." When you query revenue numbers, they are accurate — always. Power BI Copilot uses a probabilistic language model; errors can occur on complex queries.
5. GDPR and Data Sovereignty
oneAgent is hosted in Frankfurt, Germany. An on-premise installation is available for organizations with strict data-protection requirements — in regulated industries, for example. Your data never leaves the EU.
6. You Want No Vendor Lock-In
oneAgent is data-source agnostic. If you switch your ERP tomorrow, you connect the new system. With Power BI Copilot, you are tied to the Microsoft ecosystem.
Who Should Use Which Tool? — Decision Matrix
| Criterion | oneAgent | Power BI Copilot |
|---|---|---|
| Company size | Mid-market | 500+ employees |
| Analytics IT budget | Up to EUR 20,000/year | From EUR 60,000/year |
| BI expertise in-house | Low to medium | High (Power BI admins available) |
| Existing infrastructure | Diverse systems (SAP, Shopware, CRM) | Microsoft 365 + Fabric |
| Primary users | Business departments, management | BI department, analysts |
| Data protection requirements | High (regulated industries, on-premise) | Standard (cloud acceptable) |
| Time to value | Days (plug-and-play connectors) | Weeks to months (Fabric setup) |
Quick Recommendation
- Mid-market without Fabric: oneAgent. The cost difference speaks for itself.
- Enterprise with Fabric: Power BI Copilot as an extension of your existing setup.
- Mid-market with Power BI (no Fabric): oneAgent. Keep Power BI for dashboards, use oneAgent for ad-hoc queries.
- Regulated industries: oneAgent — on-premise option and deterministic results.
Power BI Q&A Is Being Retired — What Now?
Microsoft has announced that Power BI Q&A will be retired in December 2026. Q&A was the previous way to ask natural-language questions in Power BI — without a Fabric license.
For companies currently using Q&A, there are two options:
- Upgrade to Fabric + Copilot: At least EUR 4,900/month additional cost
- Switch to an alternative like oneAgent: From EUR 25/user/month

Frequently Asked Questions
Can oneAgent Fully Replace Power BI?
No — and that is not the goal. Power BI is a comprehensive BI tool for report creation, dashboards, and data modeling. oneAgent complements or replaces the query layer: instead of building reports, employees ask questions in a chat. Many companies use both in parallel — Power BI for complex dashboards, oneAgent for ad-hoc questions.
Do I Need Technical Knowledge to Use oneAgent?
No. Setup is handled through a guided onboarding process (from EUR 1,500). Connectors are connected via plug-and-play. Daily use requires no BI skills — you type questions in natural language, like in a chat.
What Does "Deterministic AI" Mean in oneAgent?
Conventional AI models like GPT-4 generate answers probabilistically — they "guess" based on probabilities. This can lead to hallucinations: incorrect numbers that sound plausible. oneAgent uses a deterministic AI layer that translates queries into exact database queries. The result is always traceable and correct.
How Quickly Can oneAgent Be Deployed?
Typically, setup takes a few days. During onboarding, your data sources are connected, access rights are configured, and initial queries are tested. No months-long implementation like Fabric is required.
Does oneAgent Work with My Existing Systems?
With over 550 native connectors, oneAgent covers the most common systems in the DACH mid-market: Shopware, SAP, Microsoft Dynamics, Salesforce, DATEV, various ERP and CRM systems, databases, and cloud services. If your system is not listed, nearly any data source can be connected via REST API.
What Happens to My Data?
oneAgent is hosted in Frankfurt, Germany, and is fully GDPR-compliant. Your data does not leave the EU. For organizations with special requirements, an on-premise option is available — the platform runs entirely within your own infrastructure. No data is used to train AI models.
