The verdict in three sentences
A leader steering on Excel always decides late and with disputed figures. A BI decision dashboard consolidates your sources into a single, automatically refreshed truth, which speeds up and secures decisions. In 2026, an SME dashboard runs between 8,000 and 30,000 EUR depending on source count and real-time needs.
The real cost of flying blind
The problem isn't Excel: it's manual reconciliation. Every Monday, someone exports sales, cash, stock, pastes it all into a workbook, fixes formatting errors and sends an already-stale PDF. This ritual costs time and, worse, hides weak signals: an eroding margin, a slowing client, dead stock.
A well-designed dashboard doesn't just replace that workbook. It changes decision frequency: from a passive monthly review to weekly, even daily steering on critical indicators.
What a BI dashboard costs in 2026
Price depends mostly on the number of sources to connect and the level of automation. A dashboard fed by a single CRM costs far less than a sales + accounting + stock + e-commerce consolidation.
| Scope | Connected sources | Project cost | Timeline |
|---|---|---|---|
| Essential | 1-2 (sales, accounting) | 8,000-12,000 EUR | 3-5 weeks |
| Consolidated | 3-4 (+ stock, CRM) | 13,000-20,000 EUR | 6-9 weeks |
| Advanced | 5+ (+ e-commerce, HR) | 21,000-30,000 EUR | 10-14 weeks |
| Critical real-time | flow < 15 min | +20-30% | +2-4 weeks |
Recurring costs (hosting, tool licenses like Metabase, Power BI or Superset, maintenance) run around 100 to 600 EUR per month in 2026 depending on the solution. A self-hosted open-source stack cuts licenses but requires slightly more maintenance.
Which metrics to instrument first
Common mistake: wanting to measure everything from the start. A good first dashboard focuses on 8 to 12 indicators that genuinely trigger decisions.
| Domain | Priority metric | Related decision |
|---|---|---|
| Sales | Revenue vs target, pipeline | Sales follow-up |
| Cash | DSO, receivables | Reminders, financing |
| Margin | Margin per product/client | Pricing arbitrage |
| Stock | Turnover, stockouts | Reorder, clearance |
| Production | Service rate, delays | Prioritization |
Start with the metrics whose lag costs the most. DSO and margin per client are almost always in the top 3 for SMEs.

Sophie is CFO of a 40-person industrial SME in Lyon. Each month she spends 12 hours consolidating four exports for a leadership committee that discovers figures three weeks late. Kolonell delivers a Metabase dashboard connecting ERP, accounting software and CRM, refreshed nightly. Cost: 17,000 EUR. Result: 11 hours a month recovered (~130 h/year at 50 EUR loaded = 6,500 EUR), and above all an automatic margin alert that let her renegotiate a loss-making contract, saving 22,000 EUR over the year. ROI reached in the first quarter.
FAQ
Isn't Excel enough?
Excel is still useful for one-off analysis, but it doesn't automatically consolidate multiple sources or refresh in real time. The dashboard removes manual reconciliation, often 10 to 15 hours a month in an SME.
Power BI, Metabase or Superset?
Power BI suits Microsoft environments with existing licenses; Metabase and Superset (open source) cut license costs and suit SMEs wanting data control. The choice depends on your stack and recurring budget.
How long for the first version?
An essential dashboard (1-2 sources) is delivered in 3 to 5 weeks. We favor a quickly useful first version, then enrich by iterations.
Do I need a data warehouse?
Not always. Under a few million rows, a direct connection is enough. Beyond that, a warehouse (BigQuery, dedicated Postgres) secures performance and history.
Who updates the data?
Nobody: it's automated. Connectors fetch data on a defined interval (nightly, hourly, real time). The whole point is to remove any manual entry or export.
