The verdict in three sentences
A real-time dashboard isn't a prettier Excel sheet: it's a data pipeline feeding a visualization layer at a short interval. In 2026, budget EUR 18,000-45,000 for custom, plus EUR 5,000-12,000 for ETL/ELT, with a refresh under 5 minutes. The real payoff isn't aesthetics but responsiveness: deciding in hours instead of days.
Batch vs real-time: two architectures, two budgets
Most SMBs don't need second-by-second real time. The question is: what freshness delay justifies the extra cost? Here's the 2026 comparison.
| Criterion | Batch (nightly) | Micro-batch (5-15 min) | Real-time (< 1 min) |
|---|---|---|---|
| Data freshness | day-1 | 5-15 minutes | near-instant |
| Pipeline cost | EUR 5,000-8,000 | EUR 8,000-12,000 | EUR 12,000-20,000 |
| EU hosting | EUR 80-150/month | EUR 150-300/month | EUR 250-400/month |
| Complexity | low | medium | high |
| Use case | monthly reporting | sales/production | support, logistics, fraud |
For 80% of SMBs, micro-batch at 5-15 minutes offers the best cost/benefit ratio. True real time is justified for support, logistics or anomaly detection.
Breaking down a typical project budget
A decision dashboard project splits into clear line items. Here is a 2026 estimate for a multi-source SMB (ERP + CRM + e-commerce).
| Line item | 2026 range | Detail |
|---|---|---|
| Scoping & KPIs | EUR 2,000-4,000 | workshops, indicator definition |
| Data pipeline (ETL/ELT) | EUR 5,000-12,000 | connectors, transformations |
| Modeling & warehouse | EUR 3,000-7,000 | schema, historization |
| Visualization layer | EUR 6,000-15,000 | dashboards, filters, exports |
| UAT & go-live | EUR 2,000-5,000 | testing, training |
| EU hosting (year 1) | EUR 1,000-4,800 | server, backups |
A data engineer / BI consultant day rate is EUR 620-800 in 2026 (ballpark). Average timeline: 6 to 10 weeks from scoping to production.

Mini case study
Marc, who runs a 60-person manufacturing-and-distribution SMB, loses 6 hours of committee time every week reconciling divergent Excel exports. He invests EUR 28,000 in a micro-batch dashboard (10-min refresh) consolidating sales, production and support. Result: the 6 weekly reconciliation hours vanish, about 300 hours/year. Valued at EUR 45/h, that's EUR 13,500/year recovered, not counting decisions made 2 days earlier on stockouts. Payback in roughly 2 years, before responsiveness gains.
FAQ
Does a real-time dashboard replace my ERP? No, it reads it. It aggregates data from the ERP, CRM and other sources for a consolidated view the ERP alone doesn't give.
Why does the pipeline cost more than the charts? Because 70% of the work is invisible: cleaning, reconciling and making data reliable. A beautiful chart on wrong data is worthless.
Do I really need real time? Rarely to the second. Micro-batch (5-15 min) covers most steering needs at 30-40% lower cost.
Where is the data hosted? On EU hosting (EUR 80-400/month depending on freshness), GDPR-compliant, with automatic backups.
What's the implementation timeline? 6 to 10 weeks for a standard multi-source scope, including 2-3 weeks for a first usable POC.
