The verdict in three sentences
As long as the cash forecast lives in an Excel workbook fed by hand from 3 banks and the ERP, the CFO loses about 2 days a month and steers with already-stale data. A real-time cash dashboard (Power BI, Metabase or a custom decision app) costs EUR 15,000-45,000 in 2026, PSD2 bank connectors included. It turns manual consolidation into a reliable 13-week cash forecast refreshed every night.
What a cash dashboard costs in 2026
Three building blocks shape the budget: the BI platform, the connectors (banks + ERP) and maintenance. Here are the 2026 ballpark figures.
| Item | Packaged BI (Power BI/Metabase) | Custom decision app |
|---|---|---|
| Initial build | EUR 15,000-28,000 | EUR 30,000-45,000 |
| Bank + ERP connectors | EUR 8,000-14,000 | EUR 12,000-18,000 |
| Licences | EUR 10-20/user/month | own infra EUR 80-250/month |
| Maintenance | EUR 500-900/month | EUR 900-1,400/month |
| Timeline | 6-9 weeks | 9-12 weeks |
| PSD2 aggregation | Yes | Yes |
Packaged BI covers a standard need (balances, forecast, collections). Custom is justified for complex cash scenarios, multi-entity setups or deep integration into your systems.
What real time actually changes
The gain isn't just comfort: it's measured in CFO days and decision quality. Before/after for a multi-bank SME.
| Metric | Before (Excel) | After (real-time dashboard) |
|---|---|---|
| Consolidation time | 2 days/month | < 2 h/month |
| Data freshness | 5-10 days old | same day or overnight |
| Reliable forecast horizon | 4-6 weeks | 13 weeks |
| Banks aggregated | manual entry | 100% via PSD2 |
| Cash-strain detection | reactive | anticipated (alerts) |
| Consolidation errors | frequent | near zero |
Result: the CFO shifts from reporting to analysis, anticipates strain and negotiates credit lines with up-to-date numbers.

Mini case study
Sarah, CFO of a distribution mid-cap in Rotterdam with 4 bank accounts and one ERP, consolidated cash 2 days a month in Excel, with a forecast reliable to 5 weeks. Kolonell delivers a custom Metabase dashboard at EUR 26,000 + PSD2 connectors at EUR 11,000 + EUR 700/month maintenance. Consolidation drops to 1.5 h/month (about 22 h/month freed), forecast extended to 13 weeks. Over a year, about 250 CFO hours redeployed to analysis and two anticipated cash strains avoided costly overdrafts: ROI reached within the first half-year.
FAQ
How does PSD2 bank aggregation work? Through a licensed aggregator, the dashboard pulls balances and transactions from your banks via secure API automatically. No re-keying, and movements are available same-day or overnight.
Power BI or a custom app? For a standard need, Power BI or Metabase (EUR 15,000-28,000) is enough. Custom (EUR 30,000-45,000) is justified for multi-entity, complex scenarios or heavy system integration.
How long to deploy? Budget 6 to 9 weeks for packaged BI, 9 to 12 weeks for a custom app, bank and ERP connectors included.
Is the 13-week forecast reliable? Yes, once recurring inflows and outflows are fed automatically. Reliability typically moves from 5-6 weeks to a usable 13 weeks.
What maintenance budget should we plan? Between EUR 500 and 1,400/month depending on complexity: connector monitoring, metric changes, adapting to bank API updates.
