The verdict in three sentences
A custom BI decision dashboard costs 20,000 to 70,000 EUR in 2026 for an SME/mid-market firm, versus 10 to 40 EUR/user/month in Power BI or Metabase licenses. The choice depends on source complexity (ERP, CRM, accounting) and your data governance needs. ROI shows up as close days saved and decisions made on consolidated figures rather than scattered Excel exports.
Custom vs licenses: the real comparison
An off-the-shelf tool is enough to visualize already-clean data. Custom pays off when you must model, clean and automate heterogeneous sources.
| Approach | Upfront cost | Recurring | Timeline | Fits |
|---|---|---|---|---|
| Power BI licenses only | 0 - 3,000 EUR | 10 - 20 EUR/user/month | 2-4 wks | Already-clean data |
| Self-hosted Metabase | 5,000 - 12,000 EUR | 50 EUR/month hosting | 3-5 wks | In-house tech team |
| Custom BI (model + ETL) | 20,000 - 45,000 EUR | 12%/year maintenance | 6-9 wks | Multiple sources |
| Full decision platform | 45,000 - 70,000 EUR | 12%/year maintenance | 9-12 wks | Multi-entity firms |
The hidden cost of licenses-only is the human time spent preparing data upstream, often underestimated.

Mini case study
Mehdi, CFO of a 90-person trading firm, replaces 11 Excel files with a BI dashboard at 38,000 EUR, plus 150 EUR/month hosting and 12%/year maintenance. Month-end close drops from 8 to 5 days, i.e. 3 days/month freed for two controllers, valued at roughly 2,400 EUR/month. The 15 consolidated KPIs replace hours of manual consolidation. Over 12 months, the time saved covers most of the investment, before better commercial decisions.
FAQ
Isn't Power BI enough? If your data is already centralized and clean, yes. As soon as you cross ERP, CRM and accounting with business rules, you need a modeling and ETL layer licenses alone don't provide.
How many indicators should we track? Better 12 to 15 truly actionable KPIs than 60 ignored charts. Good scoping removes vanity metrics and prioritizes what triggers a decision.
Where to host the data? With a regional host to stay compliant, with encryption and fine-grained access control. Count 80 to 150 EUR/month for an SME.
How often does data refresh? A nightly daily refresh suits most SMEs; real time only matters for specific operational flows and costs more.
What maintenance budget? About 12%/year: sources evolve, new KPIs are added and connectors must follow source-software updates.
