Quick answer. Finthesis is a turnkey financial-steering solution, designed for finance professionals (accountants, CFOs, controllers) and small and mid-sized businesses: reporting, data visualization, budgets and cash-flow forecasts, ready to use. Power BI is a custom business intelligence tool (from about USD 14/user/month), very flexible but one you must build and maintain. Your choice depends on the effort you can devote to setup, your need for flexibility, your budget and your internal skills.
2026 context: two steering philosophies#
Steering your finances requires up-to-date dashboards: cash, margin, profitability, forecast. Two approaches differ.
- The turnkey business solution (Finthesis) ships ready-to-use financial models: you import your accounting data and quickly get relevant outputs.
- Custom business intelligence (Power BI) offers near-total modeling freedom, at the cost of building and maintaining it.
This is not a "winner-loser" duel, but a trade-off between setup speed and flexibility.
Finthesis at a glance: ready-to-use financial steering#
Finthesis is a platform for financial reporting, data visualization, business intelligence and business planning, designed for finance professionals and finance departments alike.
- Features: budgeting (operating budget and cash-flow forecast), cost accounting, building multi-year forecasts from imported historical data, scenario testing, and data visualization (custom charts).
- Strengths: ready-to-use financial models, fast setup, a business language close to finance and accounting.
- Best for: accountants, firm staff, part-time CFOs, management controllers, small and mid-sized businesses.
- Recognition: according to the Palmarès du Chiffre, Finthesis is among the recognized reporting tools, with a first place in the reporting category in 2024 and a second place in 2025.
Power BI at a glance: custom BI#
Power BI is Microsoft's business intelligence tool, already detailed in our comparison of Power BI, Tableau and Looker Studio.
- Pricing: Power BI Pro from about USD 14/user/month; Premium Per User for extended capabilities.
- Strengths: near-total modeling flexibility, integration with the Microsoft ecosystem, a large community.
- Limits: you must build the financial models (the DAX formula language requires skill), then maintain them; without a ready-made business model, setup takes longer.
- Best for: organizations with internal data skills and a need for deep customization.

Effort vs flexibility at a glance#
| Axis | Finthesis | Power BI |
|---|---|---|

Special cases#
- Accounting firm producing client reporting: Finthesis, with its business models, speeds up output production.
- Part-time CFO working across several SMEs: Finthesis standardizes dashboards from one engagement to another.
- Organization with a data team and cross-functional needs (beyond finance): Power BI, with its flexibility, covers a broader scope.
- Very tight licence budget but internal skills available: Power BI Pro stays very accessible if you can build your models.
Points of vigilance in 2026#
1. Total cost, not just the licence#
For Power BI, the real cost includes building the models and maintaining them, often higher than the licence price. For Finthesis, ask for a quote including configuration and training. Compare the full cost over the first year and the next ones.
2. Source-data quality#
A steering tool is only as good as the data it presents. The quality of your accounting (up-to-date entries, reconciliations) drives the relevance of the dashboards, whatever the tool.
3. GDPR and hosting#
These tools process sensitive financial data. Require a data processing agreement (DPA) compliant with Article 28 of the GDPR, check hosting and frame any out-of-EU transfers (Chapter V of the GDPR). A steering tool does not replace statutory accounting archiving (ten-year retention, art. L123-22 of the Commercial Code).
4. User adoption#
A steering tool's value lies in regular use. A well-adopted turnkey tool beats a custom dashboard no one consults. Assess how easily your teams take it up.
Our chartered-accountant analysis#
In our steering engagements, we observe that turnkey solutions speed up the start, while custom tools are justified when needs go beyond the strictly financial scope. The "Finthesis or Power BI?" question often comes down to another: do you want to buy ready-made financial models, or build your own? A firm or part-time CFO producing standardized financial outputs for several structures saves valuable time with a business solution like Finthesis. An organization with cross-functional analysis needs beyond finance, and internal data skills, will benefit from Power BI's flexibility.
Our recommendation: start from the expected result (which dashboards, how often, for whom) and the time you can devote to setup. As a chartered accountant and statutory auditor, we remind clients that the tool does not create reliability: it is the quality of the source accounting that gives steering its value.
Hayot Expertise advice. Decide on the speed-versus-flexibility trade-off. If you want fast, standardized, business-oriented financial outputs, Finthesis fits well. If you have internal data skills and custom cross-functional needs, Power BI offers more freedom. In both cases, first ensure the reliability of your source accounting, check GDPR and hosting, and assess real user adoption before committing.
Frequently asked questions
Is Finthesis a competitor to Power BI?+
Not exactly. Finthesis is a business financial-steering solution, with ready-to-use models. Power BI is a general-purpose BI tool, very flexible but one you must build. They overlap on financial output, but follow different logics: ready-to-use versus custom.
Which is faster to set up?+
Finthesis, generally, because it ships ready-to-use financial models: you import your data and quickly get outputs. Power BI requires building the models, which lengthens setup but offers more customization.
What is the price of Finthesis?+
Pricing is generally on quote, by scope and user profile. Ask for a quote including configuration and training, and compare it to the full cost of Power BI (licence plus building and maintaining the models).
Can Power BI do cash-flow forecasting?+
Yes, but you must build the model. Finthesis natively offers budgeting and multi-year cash-flow forecasting from historical data. With Power BI, this kind of model is designed from scratch, which takes skills and time.
Do I need technical skills for Power BI?+
Yes, in practice. Building financial models in Power BI requires mastering its logic and formula language (DAX). Finthesis, business-oriented, mainly requires financial and accounting understanding, closer to the daily work of a firm or finance department.
Do these tools replace the accountant?+
No. They are output and decision-support tools. The reliability of the figures depends on the source accounting, and analysis and advice are the accountant's role. The tool informs the decision; it does not replace professional judgment.
