The verdict in three sentences
A real-time dashboard (websockets, continuous ingestion, alerts) tracking production, stock and SLAs live costs 20,000 to 45,000 EUR in 2026, delivered in 8 to 14 weeks, with 150-500 EUR/month of streaming infrastructure. It is only justified when stale data is expensive: an undetected incident, a stockout, a breached SLA. For decision-level management, an hourly or daily refresh is simpler and far cheaper.
The line items of a real-time dashboard
The premium over a classic dashboard comes from continuous ingestion, websockets and an alert engine that must stay reliable 24/7.
| Line item | 2026 range (EUR) | Detail |
|---|---|---|
| Discovery & real-time KPIs | 2,000 - 5,000 | Target latency, alert thresholds |
| Ingestion pipeline | 5,000 - 12,000 | Kafka/queue, machine connectors |
| Real-time layer (websockets) | 4,000 - 9,000 | Live push, reconnect, backpressure |
| Alert engine | 3,000 - 7,000 | Rules, escalation, email/SMS/Slack |
| Live UI (animated charts) | 3,000 - 8,000 | Recharts/D3, big-screen mode |
| UAT + monitoring | 2,000 - 5,000 | Load testing, observability |
| Total | 20,000 - 45,000 | 8 to 14 weeks |
2026 order of magnitude: an industrial operations dashboard (machine sensors, SLA alerts) lands near 32,000 EUR + ≈ 300 EUR/month infra.
Real-time vs periodic refresh
| Criterion | Real-time (websockets) | Periodic (polling) |
|---|---|---|
| Data latency | < 2 seconds | 1 min to 24 h |
| 2026 build cost | 20,000 - 45,000 EUR | 12,000 - 30,000 EUR |
| Monthly infra | 150 - 500 EUR | 30 - 120 EUR |
| Complexity | High (streaming, alerts) | Moderate |
| Best for | Production, SLA, monitoring, trading | Sales, margin, HR, reporting |
| Proactive alerts | Native | Delayed |
| Server load | Continuous | Per interval |
Decision rule: only pay for real-time if the value of reacting within seconds beats the premium. For 90 % of executive dashboards, periodic is plenty.
Mini case study
Sofiane, operations director at a logistics firm in Rungis (3 warehouses). His picking shortfalls were detected 2-4 hours late, triggering client penalties for missed SLAs. He commissions a real-time dashboard at 33,000 EUR + 300 EUR/month infra, with automatic alerts the moment a line breaches its threshold.
Before: 14 SLA incidents/month at ≈ 800 EUR penalty = 11,200 EUR/month. After go-live, detection in < 1 min and immediate reaction: incidents down to 3/month, i.e. 8,800 EUR/month saved (105,600 EUR/year). Payback in under 5 months, infra included.

FAQ
How does it differ from a classic BI dashboard?
Classic BI refreshes periodically (hourly, daily) and supports decisions. Real-time pushes data continuously (< 2 s) and supports reacting to operational incidents. Architectures and costs differ sharply.
Do I really need real-time?
Only if late data costs money: SLAs, stockouts, safety, machine supervision. For sales, margin or HR, an hourly refresh suffices and costs 40 % less.
How much does streaming infrastructure cost monthly?
Depending on event volume: 150 EUR/month for a moderate stream, up to 500 EUR/month for several thousand events/second with high availability.
Can we add SMS and Slack alerts?
Yes: the alert engine routes by rules to email, SMS, Slack or Teams, with escalation if no one acknowledges. Budget 3,000-7,000 EUR for this component.
What is the setup timeline?
Expect 8-14 weeks depending on source count and availability criticality. A first useful stream can ship in 5-6 weeks, then be enriched.
