The verdict in three sentences
In Berlin in 2026, a custom business intelligence (BI) dashboard ranges from 16 000 to 55 000 EUR depending on the number of connected sources and indicator complexity. It ships in 6 to 12 weeks and enables decisions up to 30 % faster. The real cost is not the dashboard: it is every decision made blind for lack of reliable data.
How much a BI dashboard costs in Berlin
Budget depends mostly on the number of sources to connect, upstream data quality and the level of interactivity. 2026 ranges.
| Item | 2026 range (EUR) | Detail |
|---|---|---|
| Scoping & KPI definition | 2 000 - 5 000 | leadership workshops |
| Source connection (ETL) | 4 000 - 16 000 | 2 to 8 sources |
| Modelling & data warehouse | 3 000 - 13 000 | cleansing, joins |
| Dashboard design | 5 000 - 19 000 | interactivity, filters |
| Tool licence (per user) | 0 - 20 /month | Power BI, Metabase |
| Annual maintenance | 10 - 15 % of project | KPI evolution |
Off-the-shelf tool or custom build?
The choice is between adopting a market tool configured for you, or building a fully custom solution. Comparison.
| Criterion | Power BI | Metabase (self-hosted) | Custom (React/D3) |
|---|---|---|---|
| 2026 licence cost | 0 - 20 EUR/user/month | 0 EUR (hosting) | hosting 20-100 EUR |
| Initial setup | 9 000 - 27 000 EUR | 7 000 - 22 000 EUR | 27 000 - 55 000 EUR |
| Timeline | 4 - 8 weeks | 4 - 8 weeks | 8 - 12 weeks |
| UI customisation | medium | medium | full |
| Best for | Microsoft ecosystem | cost control, GDPR | unique experience |
For 80 % of Berlin SMBs, Power BI or Metabase configured to your needs offers the best cost/value ratio. A full custom build is justified when the dashboard becomes a client-facing product or a differentiator.
The hidden factor: data quality
A beautiful dashboard wired to dirty data is worthless. Data quality often represents 30 to 40 % of project effort: deduplication, reference harmonisation, missing-value handling. Budgeting this line avoids the trap of the dashboard nobody dares use because the numbers are wrong.
Mini case study
Marc, managing director of a 60-employee B2B distribution SMB in Berlin. His monthly reporting takes 3 days to consolidate in Excel and arrives 10 days late. He invests 30 000 EUR in a Power BI dashboard connected to his ERP, CRM and accounting, plus 14 EUR/user/month for 12 users (168 EUR/month).

Outcome: real-time reporting, 3 days/month freed for management control (at 45 EUR/loaded hour, 24 h x 45 x 11 months = 11 880 EUR/year). Above all, faster restocking decisions cut stockouts by 18 %: on 40 000 EUR of estimated lost sales per year, that recovers 7 200 EUR. Total ROI: ~19 000 EUR/year against 30 000 EUR in year one. Paid back in ~18 months, then strongly positive.
FAQ
How many sources can be connected?
Typically 2 to 8 for an SMB: ERP, CRM, accounting, e-commerce, spreadsheets, marketing tools. Each source adds 1 500 to 4 000 EUR depending on API complexity.
Power BI or Metabase: which to choose?
Power BI if you already run Microsoft 365 and want fast adoption. Metabase (open source, self-hosted) if you prioritise cost control and hosting your data in Europe (GDPR).
How soon will I get my first dashboard?
A pilot dashboard on a single source can ship in 3 to 4 weeks. The full multi-source version takes 6 to 12 weeks depending on the data quality to clean.
Do I need an in-house data analyst?
Not necessarily at launch: the vendor delivers self-serve dashboards. But beyond 50 users or to evolve KPIs regularly, an internal data owner strongly accelerates value.
What does maintenance cover?
Between 10 and 15 % of project cost per year: adding KPIs, adapting to source changes, fixing connectors and tool version upgrades.
