Financial Analysis Agent

A comprehensive financial analysis skill that enables AI agents to produce defensible, CFO-ready financial outputs. Every technique here is grounded in standard accounting practice (US GAAP / IFRS compatible) and designed for agents operating on real financial data.

When to Use

• Monthly/quarterly financial close cycles
• Variance analysis on budget vs actual results
• Cash flow forecasting and 13-week rolling dashboards
• Generating CFO commentary and board-ready narratives
• Ratio analysis for lending covenants or investor reporting
• AR/AP aging analysis and collections prioritization
• Bank reconciliation pattern matching

When NOT to Use

• Tax return preparation or tax advisory (use a tax compliance skill)
• Audit opinions or attestation work (requires human CPA sign-off)
• Regulatory filings (SEC, state filings — requires compliance review)
• Valuation work (DCF, comps — requires a valuation-specific skill)
• Payroll processing or HR-related financial work

1. Variance Analysis Methodology

Variance analysis decomposes the difference between budget and actual into price, volume, and mix components.

Price Variance

Measures the impact of actual price differing from budgeted price, holding volume constant.

Price Variance = (Actual Price - Budget Price) × Actual Volume

Example:

Budget: 1,000 units @ $50 = $50,000
Actual: 1,000 units @ $53 = $53,000
Price Variance = ($53 - $50) × 1,000 = $3,000 Unfavorable (cost) or Favorable (revenue)

Volume Variance

Measures the impact of actual volume differing from budgeted volume, at budgeted price.

Volume Variance = (Actual Volume - Budget Volume) × Budget Price

Example:

Budget: 1,000 units @ $50 = $50,000
Actual: 1,100 units @ $50 = $55,000
Volume Variance = (1,100 - 1,000) × $50 = $5,000 Favorable (revenue)

Mix Variance

When multiple products exist, mix variance isolates the impact of selling a different proportion than planned.

Mix Variance = (Actual Mix% - Budget Mix%) × Actual Total Volume × Budget Margin

Three-Way Reconciliation

Always reconcile: Total Variance = Price Variance + Volume Variance + Mix Variance

If the three don't sum to the total, you have a calculation error. Never present unreconciled variances.

Materiality Thresholds

Adjust thresholds based on entity size. A $2M company uses different thresholds than a $200M company.

2. Cash Flow Forecasting (13-Week Rolling)

The 13-week cash flow forecast is the standard tool for liquidity management. It covers one full quarter on a weekly basis.

Collection Assumptions

Build collection curves from historical data:

Invoice Terms    Collection Pattern
─────────────────────────────────────
Net 30           Month 1: 15%, Month 2: 70%, Month 3: 12%, Bad debt: 3%
Net 15           Month 1: 80%, Month 2: 17%, Bad debt: 3%
COD              Month 1: 97%, Bad debt: 3%

Forecast Accuracy Tracking

Every week, compare last week's forecast to actual:

Forecast Accuracy = 1 - |Actual - Forecast| / |Forecast|
Target: >90% accuracy on 1-week forecast, >80% on 4-week

Red Flags

• Closing cash below minimum balance requirement in any week
• Three consecutive weeks of declining cash
• Collections falling below 85% of forecast
• Concentration: any single customer >25% of weekly inflows

3. Month-End Close Checklist
