Use pandas to aggregate historical receipts and payments by month, then apply seasonal factors and growth rates to project future periods. The Skill's CashFlowManager class generates 12-month rolling forecasts with confidence intervals and cumulative cash positions.

Calculate NPV by discounting each future cash flow at your discount rate and subtracting the initial investment. IRR is found by solving for the rate where NPV equals zero, using scipy's fsolve function as shown in the InvestmentAnalyzer class.

Budget variance analysis compares actual spending against budgeted amounts by department and period. The Skill uses SQL queries to compute variance percentages and classify each department as On Track, Over Budget, or Under Budget based on a 5% threshold.

No, it focuses on financial planning, analysis, and internal reporting rather than filing taxes or submitting regulatory documents. It supports tax planning strategy and compliance documentation, but actual filings require licensed accounting professionals.

Forecast accuracy degrades because seasonal factors and growth assumptions are extrapolated from historical patterns that may not hold. The Skill mitigates this with confidence intervals of plus or minus 15% and recommends 90-day liquidity visibility as the reliable horizon.
