The verdict in three sentences
A decision dashboard only earns its keep if it consolidates your sources in real time and speaks your KPIs, not the software's. In 2026 two paths compete: an off-the-shelf tool (Power BI, Metabase, Looker) quick to start but with recurring licences, or a custom dashboard at EUR 16,000-48,000 built for your processes. The tipping point is the number of sources to connect and the ETL complexity.
Off-the-shelf or custom: the comparison
The choice is not just the entry price. An off-the-shelf tool is cheap up front but bills per user and stiffens the moment your metrics leave the beaten track. Custom costs more to build but has no per-seat licence and fits your business exactly.
| Criterion | Off-the-shelf | Custom dashboard |
|---|---|---|
| Upfront cost | EUR 0 - 5,000 | EUR 16,000 - 48,000 |
| Licence | EUR 10 - 60/user/mo | None (hosting only) |
| Setup time | 2 - 5 weeks | 6 - 12 weeks |
| Business-specific KPIs | Limited | Unlimited |
| ETL / complex sources | Paid add-ons | Built in |
| Data control | Shared with vendor | Total |
| Extensibility | Vendor-capped | Free |
What makes up the custom budget
The cost of a custom dashboard is not the display but the data pipeline: connect, clean, aggregate, historise. Here is a typical 2026 breakdown.
| Item | Share of budget | Order of magnitude (EUR) |
|---|---|---|
| Source connection (API/DB) | 20 % | 3,200 - 9,600 |
| ETL and data model | 30 % | 4,800 - 14,400 |
| Dataviz and interface | 25 % | 4,000 - 12,000 |
| Roles, rights, security | 10 % | 1,600 - 4,800 |
| Testing and deployment | 15 % | 2,400 - 7,200 |
| Annual maintenance | - | 2,200 - 6,500/yr |
Mini case study
Lena, owner of a 30-person trading SME in Berlin, juggles her ERP, her CRM and three Excel files. An off-the-shelf tool at EUR 40/user/month for 15 users would cost EUR 7,200/year in licences without solving margin aggregation by product family. She picks a custom dashboard at EUR 30,000 with ETL. Over five years, custom totals 30,000 + 16,000 maintenance = EUR 46,000, versus EUR 36,000 in licences for the tool, but with KPIs the tool could never produce. The decision hinges on the value of the metrics, not a EUR 10,000 gap.

Are Power BI or Metabase enough for an SME?
Often yes for standard reporting. They hit their limits when your KPIs cross several heterogeneous sources or need business logic the tool cannot natively model.
How long to deliver a custom dashboard?
Expect 6 to 12 weeks. The bulk of the work is ETL and data reliability, not charts. A usable core can land as early as week 6.
What is ETL and why is it costly?
ETL extracts, transforms and loads your data into a clean model. It is 30 % of the budget because it drives reliability: a beautiful chart on wrong data is worthless.
Does custom really avoid licences?
Yes. You only pay hosting (often EUR 50-200/month). No per-user cost, which becomes decisive beyond 10-15 users.
Can we start off-the-shelf then migrate?
Yes, a sound strategy: validate the useful KPIs with Metabase, then internalise as custom once the need is stable and the user count justifies the investment.
