The verdict in three sentences
A custom BI (business intelligence) dashboard costs 12,000 to 40,000 EUR excl. tax in 2026 depending on connected sources and warehouse depth. A Power BI or equivalent licence costs 10 to 20 EUR per user per month, but assumes someone models your data. The real cost is not the tool: it is preparing and making data trustworthy.
Custom vs licence: how to decide
Two worlds coexist. Self-service licences (Power BI, Metabase, Looker Studio) are cheap to run but need in-house skills. Custom builds bundle connectors, a warehouse and governance, and run without a resident BI expert.
| Criterion | Self-service licence | Custom BI |
|---|---|---|
| Upfront cost | 0 - 4,000 EUR | 12,000 - 40,000 EUR |
| Recurring cost | 10 - 20 EUR/user/month | 150 - 600 EUR/month hosting |
| Setup time | 2 - 4 weeks | 6 - 12 weeks |
| In-house skill required | High | Low |
| Connected sources | 1 to 3 simple | 5+ heterogeneous |
| Real time | Limited | Yes |
For an SME with no data analyst, custom is often cheaper over 24 months because it removes dependence on a scarce resource.
What makes up a BI budget in 2026
BI project pricing breaks down into rarely displayed line items. Here they are for a standard multi-source project.
| Line item | 2026 cost (EUR excl. tax) | Share of budget |
|---|---|---|
| Connectors / ingestion | 3,000 - 8,000 | 20-25 % |
| Data warehouse | 4,000 - 12,000 | 25-30 % |
| Modelling / KPIs | 3,000 - 9,000 | 20-25 % |
| Dashboards / UX | 2,000 - 7,000 | 15-20 % |
| Training / change management | 1,000 - 4,000 | 8-10 % |
Warehouse hosting (cloud) adds 150 to 600 EUR/month depending on volume and refresh frequency. These figures are a 2026 order of magnitude.
Mini case study
Thomas, head of a 40-person distribution SME in Nantes, spends 2 days per month manually consolidating sales, margin and stock from 4 Excel files and his ERP. He invests 19,000 EUR excl. tax in a custom BI connected to ERP and CRM, with real-time dashboards. He reclaims 16 days per year (about 6,400 EUR of executive time) but above all spots 3 recurring stock-outs worth 42,000 EUR in lost sales over the year. The project pays for itself in under 6 months from reduced stock-outs alone.

FAQ
How much does a BI dashboard cost for an SME in 2026?
A custom project runs from 12,000 to 40,000 EUR excl. tax. A licence approach costs 10 to 20 EUR/user/month plus in-house modelling time.

Yes if you have someone able to model the data. Otherwise, the hidden cost is a profile at 300-450 EUR/day to build and maintain the reports.
How long to a first usable dashboard?
Expect 2 to 4 weeks self-service and 6 to 12 weeks for a custom multi-source BI with a warehouse.
Can we get real time?
Yes, but continuous refresh raises hosting cost by 20 to 40 %. Many SMEs settle for hourly refresh, which is plenty.
