# Financial-plan-builder
A spreadsheet that lives in version control. Reads a YAML config,
emits a monthly cash projection with the numbers you actually need
to make funding-vs-runway decisions.
## Disclaimer
This skill produces numbers from a YAML config. It does not:
- Advise on whether to raise capital.
- Predict revenue.
- Account for taxes (the skill emits a `[TAX]` flag wherever tax
treatment matters; the operator/accountant fills in).
- Model complex equity, debt, or warrant structures.
- Replace an accountant or financial controller for material
decisions (audited reports, tax filings, due diligence).
If the YAML inputs are wrong, the output is wrong. The skill's
value is consistency — the same config produces the same projection
every time, so the operator can iterate on the inputs (what if I
hire one engineer in month 4 instead of month 2?) without rebuilding
the spreadsheet.
## Input — `finances/plan.yml`
The skill reads `finances/plan.yml` at the repo root (or a path the
operator passes). Example:
```yaml
plan:
name: 2026 H1 projection
starting_balance_usd: 180000 # cash in bank on day 1
start_date: 2026-01-01
horizon_months: 12
revenue:
# MRR streams. The skill compounds growth at the configured rate.
