The verdict in three sentences
A decision-making BI dashboard costs between 8,000 and 30,000 EUR excl. tax in 2026, depending on the number of sources (ERP, CRM, e-commerce), calculation complexity and customization level. The typical timeline is 6 to 10 weeks and most of the budget goes into data connectors, not charts. The right trade-off is between an off-the-shelf tool (Power BI, Metabase) and a custom dashboard: the former is fast, the latter fits your business rules.
How much does a BI dashboard cost in 2026
Price mostly comes down to the data: cleaning, connecting and making it reliable is 60 to 70% of the effort. Here are the 2026 ranges.
| Scope | Connected sources | 2026 cost (EUR excl. tax) | Timeline |
|---|---|---|---|
| Single-source dashboard | 1 (e.g. e-commerce) | 8,000 - 12,000 | 3-4 wks |
| Standard multi-source dashboard | 2-3 | 12,000 - 18,000 | 5-7 wks |
| Consolidated dashboard + alerts | 3-4 | 18,000 - 24,000 | 7-9 wks |
| Custom decision platform | 4+ | 24,000 - 30,000 | 8-10 wks |
Add data-flow maintenance of 150 to 600 EUR excl. tax/month: APIs evolve, data schemas change, and a broken flow makes the dashboard useless.
Power BI / Metabase vs custom dashboard
The question isn't "which is better" but "which fits your needs". An off-the-shelf tool covers 70% of SMEs; custom wins when indicators are specific to your business.
| Criterion | Power BI / Metabase | Custom dashboard |
|---|---|---|
| 2026 initial cost | 8,000 - 16,000 EUR | 18,000 - 30,000 EUR |
| Monthly license | 10 - 20 EUR/user | 0 (self-hosted) |
| Setup timeline | 3-6 weeks | 7-10 weeks |
| Business-specific indicators | Limited | Full |
| Integration into your app | Weak | Native |
| Annual maintenance cost | 1,500 - 4,000 EUR | 2,500 - 7,000 EUR |
Practical 2026 rule: start off-the-shelf, switch to custom when licenses exceed 6,000 EUR/year or when indicators get too specific.
Mini case study
Julien, CFO of a services SME in Lyon (60 employees), consolidates revenue, margin and cash by hand in Excel every month: 2 days a month, i.e. 16 hours at a loaded cost of 45 EUR/hour = 720 EUR/month, with reporting always a month late.
He commissions a multi-source dashboard (ERP + CRM + bank) for 19,000 EUR excl. tax, maintenance 300 EUR/month. He saves 720 EUR/month of time and, above all, monitors in real time: a cash alert avoids an overdraft costing 1,800 EUR/year. Net annual cost: 3,600 EUR maintenance. Annual gain: 8,640 + 1,800 = 10,440 EUR. ROI on the initial investment: about 14 months, then recurring net benefit.

FAQ
Is Power BI enough for an SME?
In 70% of cases, yes: 8,000 to 16,000 EUR setup and 10 to 20 EUR/user/month. Custom becomes relevant beyond 6,000 EUR of annual licenses or for very specific indicators.
Why does BI cost more than expected?
Because 60 to 70% of the budget goes into connecting and cleaning data, not charts. A poorly structured source can add 3,000 to 6,000 EUR.
How long for a first dashboard?
A single-source dashboard ships in 3 to 4 weeks. A consolidated multi-source dashboard with alerts takes 7 to 9 weeks.
Do I need a data warehouse?
Not always. Below 3-4 sources, a connector layer is enough. Beyond that, a warehouse makes everything reliable for an extra 5,000 to 10,000 EUR.
What maintenance budget should I plan?
Count 150 to 600 EUR excl. tax/month to maintain flows, adapt connectors and evolve indicators. That is what keeps a dashboard always up to date.
