Konsolidat. It is MIT-licensed EPM whose job is the group close — FX, CTA, intercompany elimination, NCI — not a dashboard and not a general ledger. Results land in Excel through =K.EPM(). The engine is ClickHouse + dbt. Honest about what it is not: no OneStream Marketplace, no DIY spreadsheet pack.
Most “open source finance” tools stop at GL or BI. Group consolidation needs ownership, eliminations and currency. That is the bar.
Trading, inventory profit, dividends, IC loans — configurable, not a spreadsheet workaround. IFRS engine →
NCI from a time-variant ownership tree, including mid-period and step acquisitions.
Closing / average / historic rates by account type; CTA computed and balanced automatically.

|---|---|---|---|---|
| Group close (IC / NCI / CTA) | Engine-driven | Manual / fragile | Strong, licensed | Usually absent |
| License | $0 MIT | $0 tools | Six–seven figures | Often $0, wrong job |

| Tests on every close | 139 named assertions | None | Vendor-controlled | Varies |
Konsolidat — MIT-licensed multi-entity IFRS/GAAP close with IC, NCI, FX and CTA, Excel via =K.EPM(), tested on every run. Other open-source finance tools are usually GL or BI, not statutory group consolidation.
Yes. Configurable IC elimination and NCI from a time-variant ownership tree. Detail: open-source IFRS consolidation.
Excel stays the interface. The engine holds ownership, eliminations and business-combination journals in version-controlled SQL. Excel-native consolidation.
