Why Konsolidat?
Because excellent analysis thrives on Excel.
The Problem
Corporate Performance Management is a $5B market dominated by five vendors — Tagetik, OneStream, Anaplan, Planful, Prophix — all charging $150K–$350K per year in license fees alone. Implementation adds another $50K–$350K. Three-year total cost: $200K–$1.4M.
For what?
- A consolidation engine your controller could describe on a whiteboard
- FX translation rules that haven't changed since IAS 21 was published in 1983
- Intercompany elimination that's just a matching algorithm
- Budget vs. actual variance that's subtraction
These are solved problems. The complexity isn't in the math — it's in the vendor lock-in.
Meanwhile, every finance team ends up in the same place: exporting to Excel. The $300K tool becomes a glorified data pipeline into a spreadsheet.
The Insight
What if the spreadsheet was the interface?
=EPM("USMF", 2024, "Q1", "401100")
One formula. Entity, year, period, account. The value appears. No portal, no training, no "EPM workbench." Just Excel — the tool your finance team already knows, already trusts, already lives in 8 hours a day.
Behind that formula: a modern open-source data stack that's faster, cheaper, and more transparent than any commercial EPM/CPM.
What You Get
Full IFRS/GAAP Consolidation
Not a toy. Not a demo. A production consolidation engine with:
- Multi-entity FX translation — closing rate for balance sheet, average rate for P&L
- CTA calculation — automatic Currency Translation Adjustment as an equity plug
- NCI split — group vs. non-controlling interest based on ownership percentage
- Intercompany elimination — rule-based netting across 3 IC patterns
- Top-side adjustments — manual consolidation journals (goodwill, fair value, reclassifications)
- 4-layer fully consolidated trial balance — entity + IC elimination + CTA + topside, unified
Every calculation is tested. 150+ data-quality assertions run on every build — not "trust us, it works," but assert_nci_plus_group_equals_translated with a 0.01 tolerance. The math is in the SQL. You can read it.
Driver-Based Cost Allocations
Three-step cascading allocation engine:
- IT costs distributed by headcount
- Facility costs distributed by square meters (including IT costs that landed there)
- Management fees distributed by revenue (including all prior cascaded amounts)
Each step sees amounts from prior steps. The allocation pool is verified: assert_each_step_sums_to_pool. No rounding black holes.
Budgeting with Configurable Spread
Annual budgets automatically spread across 12 months using weighted profiles:
- Even spread — $1.2M becomes $100K/month
- Seasonal retail — peaks in November (1.8x) and December (2.5x), troughs in February (0.5x)
- Custom profiles — define any 12-weight pattern
The spread is verified: assert_spread_sums_to_annual. Your annual total is preserved to the penny.
Variance Analysis That Thinks Like a Controller
Five measures, not just "actual minus budget":
| Measure | What It Tells You |
|---|---|
actual_amount | What happened |
budget_amount | What was planned |
variance_abs | The gap |
variance_pct | The gap in context |
variance_favorable | Is this good or bad? |
The favorable logic is account-type aware: revenue up = good, expense down = good. Tested with assert_favorable_revenue and assert_favorable_expense.
Excel-Native Reporting
Six worksheet functions cover every scenario — five reads plus EPMSAVE for budget write-back:
=EPM("USMF", 2024, 5, "401100") Actuals
=EPM_BUDGET("USMF", 2025, "FY", "6100") Budget
=EPM_VARIANCE("USMF", 2025, "Q1", "6100") Variance
=EPM_DEBIT("USMF", 2024, 5, "1300") Debits
=EPM_CREDIT("USMF", 2024, 5, "1300") Credits
=EPMSAVE(125000, "USMF", 2025, 5, "6100", "BUDGET_2025", "base") Write budget back
Ctrl+Shift+R refreshes an entire sheet in one HTTP round-trip. 500 formulas = 1 API call. The VBA module batches everything.
Period ranges — Q1, H1, FY — aggregate automatically. No helper columns, no SUMIFS, no manual grouping.
The Numbers
3-Year Total Cost of Ownership (~50 users)
| Tagetik | OneStream | Anaplan | Konsolidat | |
|---|---|---|---|---|
| License fees | $150K–300K | $240K–534K | $540K–1.05M | $0 |
| Implementation | $50K–200K | $50K–200K | $150K–350K | $10K–30K |
| Infrastructure | Included | Included | Included | $9K–24K |
| 3-Year Total | $200K–500K | $300K–700K | $700K–1.4M | $20K–55K |
That's not a rounding error. It's 90–97% savings.
What You Spend Instead
| Role | FTE | Annual Cost |
|---|---|---|
| Group Controller | Existing | $0 incremental |
| FP&A Analyst | Existing | $0 incremental |
| Data/Analytics Engineer | 0.3 FTE | ~$30K–50K |
| Infrastructure (ClickHouse + Frappe) | — | ~$3K–8K |
Total ongoing: ~$33K–58K/year vs. $150K–350K/year for license fees alone.
The Stack
No proprietary runtimes. No vendor SDK. No Java applets from 2008. Just tools your engineers already know:
| Component | Why This One |
|---|---|
| ClickHouse | Columnar OLAP — SUM ... GROUP BY in milliseconds, not seconds. Financial reporting is exactly this workload. |
| dbt | SQL transformations as code. Version-controlled, testable, reviewable. Your consolidation logic is in Git, not a vendor black box. |
| Frappe | Python web framework with built-in auth, roles, and REST API. No separate auth service, no API gateway, no token server. |
| Airbyte | Open-source ELT. D365 OData connector with cross_company=true. Full extraction in one sync. |
| Cube | Semantic layer for metrics and dimensions. Consistent definitions across Excel, API, and dashboards. |
| Excel + VBA | The interface your finance team chose for themselves 30 years ago. We're not fighting it — we're powering it. |
Every component is replaceable. Don't like Frappe? The API is 200 lines of Python. Don't like Airbyte? Any tool that writes to ClickHouse works. Don't like VBA? The REST API is standard HTTP JSON.
What's Tested
This isn't a prototype. 150+ assertions validate every build. The core consolidation and business-logic checks alone:
| Category | Tests | What They Prove |
|---|---|---|
| Consolidation math | 8 | translated = local x rate, group + NCI = translated, BS uses closing rate, P&L uses average |
| CTA integrity | 2 | CTA non-zero when rates differ, CTA zero for same-currency entities |
| IC elimination | 1 | Eliminations net to zero per group per period |
| Allocation completeness | 2 | Each step sums to pool, no self-allocation |
| Budget spreading | 2 | 12 periods per line, spread sums to annual total |
| Variance logic | 3 | Formula correct, revenue favorable when up, expense favorable when down |
| Trial balance | 3 | Debits = credits, GL ties to TB, all accounts in chart |
| YTD | 1 | Period 12 YTD = full year total |
| Journals | 2 | Topside journals balanced, adjustment type always populated |
| Entity tie-out | 2 | FCTB entity layer ties to consolidated TB |
Run dbt test after any change. Green means the math is right. Red tells you exactly which row broke and why.
Who It's For
Best fit: Private mid-market companies (2–50 entities) running D365 F&O who need consolidation, budgeting, and variance analysis — and don't want to spend $300K/year for the privilege.
Not for: Public companies requiring SOX-certified audit trails, or organizations with 500+ budget planners needing Anaplan-class write-back.
The honest gaps (all buildable):
- Cash flow statement (indirect method from BS deltas — ~3 days)
- Multi-GAAP dual reporting (reporting_standard dimension — ~1 week)
- Rolling forecasts (12-month sliding window — ~3 days)
These are on the roadmap. The core consolidation, allocation, and variance engine is done.
