Verify models before high-stakes decisions
Shared pattern: The model looks finished. A decision is approaching. Confidence is thinner than the deadline.
Independent verification is designed for that moment — regardless of whether the model was built by hand, inherited from a template, assisted by a spreadsheet copilot, or generated by an automated workflow.
Decision contexts where verification helps
The same discipline applies across settings — pick the rows that match your week:
| Context | What is at stake | Verification focus |
|---|---|---|
| Lender or credit meeting | Covenant headroom, debt service, collateral narrative | Covenants, cash flows, statement ties |
| Client or sponsor presentation | Credibility of outputs you are endorsing | Material drivers, scenario case, obvious defects |
| Investment committee | Capital allocation, returns, downside | Scenario provenance, key sensitivities |
| Board or credit committee | Formal approval on recorded minutes | Statement integrity, version frozen vs presented |
| Transaction close or signing | Locked numbers vs last iteration | Version comparison, last-minute edits |
| Internal sign-off | Partner or manager reliance | Assumption documentation, structural consistency |
You do not need a different product for each — you need a repeatable pass before the meeting that matters.
The independence question
Ask explicitly:
Could the same system that helped build this model also confirm it is correct — without a separate check?
If the answer is yes, you have speed — not independent assurance.
Kalc is designed as the separate check: it does not build models; it verifies them and returns severity-ranked findings with cell-level evidence.
What a useful verification pass covers (outcomes)
Designed to help you see:
- Whether formulas behave consistently across the grid
- Whether assumptions are documented and traceable
- Whether financial statements in the workbook appear to tie
- Whether the active scenario case is identifiable
- What changed since the last pass (when comparing versions)
Findings identify and suggest. You decide what to fix and what to escalate.
Synergies with consulting and internal review
Verification before the meeting complements formal review:
| Before external review | Fix clear defects; arrive with a findings summary |
|---|---|
| During iteration | Re-run after material edits |
| After review | Confirm remediations landed; catch drift |
| Between full engagements | Maintain baseline hygiene when a full review is not yet booked |
Productivity: fewer rounds on issues you could have caught early.
Reliance: you know your starting point before someone else reads the file cold.
When software is enough — and when to escalate
| Use verification passes | Escalate to human review |
|---|---|
| Iteration between meetings | Sign-off for credit/regulatory filing |
| Preparing a pack for your reviewer | Dispute or litigation support |
| Sanity check before a client call | Novel structure outside your team's experience |
Optional: verify in an automated build loop
Teams using agents or scripts to populate models can call the same independent check via API/MCP: build → verify → remediate from findings → re-verify. The agent builds; the checker stays separate.
