Open-source EPM

Open-source EPM software.

Konsolidat is open-source (MIT) Enterprise Performance Management: multi-entity consolidation, cost allocation, budgeting, forecasting and variance analysis — Excel-native via =EPM(), on a ClickHouse + dbt backend, connected to SAP and Microsoft Dynamics. The open alternative to OneStream, Anaplan and CCH Tagetik.

How it works

What makes it work.

Full EPM

The whole close

Consolidation, allocations, budgeting, forecasting, variance and reporting — not a single-purpose tool, the full performance-management scope.

Open

MIT licensed

Full source-code access, self-hostable, forkable. No license fee, no per-user pricing, no lock-in.

Multi-ERP

Your source of truth

Native connectors to SAP, Microsoft Dynamics 365 via OData, so the data flows in automatically.

The unfair advantage

Open. Owned. Tested.

Unlike every commercial EPM, Konsolidat is open source and self-hostable — the whole application to run on your own infrastructure, inspect, fork and own.
