OneStream is a capable unified CPM platform — but it typically means a seven-figure license, a 12–24 month implementation, and a closed model your team exports to Excel anyway. Konsolidat gives you the same consolidation rigor, Excel-native, on an open stack.
License plus system-integrator fees commonly run well into seven figures over three years — before your first clean close.
Enterprise CPM rollouts are long. Konsolidat is designed to reach a working consolidation in weeks, not quarters.
The logic lives in OneStream; the analysis ends up in Excel. Konsolidat makes Excel the native interface via =EPM() and keeps the engine open.
An honest comparison for a 10–500 user enterprise group over a three-year horizon. Figures are typical ranges, not quotes.
| Capability / Cost factor | Konsolidat | OneStream |
|---|---|---|
| 3-Year licensing | $0 (MIT) | $$$ six–seven figures |
| Implementation | Low–moderate | High (SI-led) |
| Time-to-value | Weeks–3 months | 12–24 months |
| Excel-native UX | ✓ =EPM() native | ⚠ Add-in |
| Statutory consolidation (IC / NCI / CTA) | ✓ Engine-driven | ✓ Strong |
| ERP integration (SAP / Dynamics / ERPNext) | ✓ via OData | ⚠ Connector / ETL |
| Source code access | ✓ Full MIT | ✗ |
| Vendor lock-in | None | High |

OneStream, like every commercial EPM, is a closed SaaS you rent — the model, the data, the roadmap, all on the vendor’s terms. Konsolidat gives you the whole application to run on your own infrastructure, inspect, fork, and own.
Konsolidat is an open-source EPM alternative to OneStream: Excel-native consolidation, allocation, budgeting and variance on a ClickHouse + dbt backend, connected to SAP, Microsoft Dynamics and ERPNext, with no license fee under MIT. It's a lower-cost, lower-lock-in option — not a feature-for-feature replacement in every niche.
Self-hosted Konsolidat has no license fee (MIT); your only cost is operating it. A managed option is available. OneStream typically involves six- to seven-figure licensing plus implementation over three years.
Yes — multi-entity IFRS/GAAP consolidation with FX translation, CTA, intercompany elimination, NCI and ownership changes, validated by 26 automated tests on every run.
Yes. Results come through =EPM() worksheet functions in the spreadsheets finance already uses — no new modeling UI to learn.
