Assumptions & Limitations
- •The model is deterministic and monthly — it projects your drivers forward with clear arithmetic, one scenario at a time.
- •Defaults are illustrative benchmarks. The paid version ships in Excel so you can wire in your real chart of accounts.
- •For a model built entirely around your business — hiring waves, fundraising rounds, working capital — commission a bespoke engagement.
- •Educational decision-support tool — not financial, investment, tax, or legal advice.
