SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Founders struggle to translate financial forecasts and goals into concrete spending plans, and often discover budget overruns too late. This Skill converts driver-based forecasts into line-by-line operating budgets, reconciles them against cash constraints, and tracks actuals versus budget with classified variance analysis. ## Core Features & Use Cases - Budget Construction: Builds budget lines using fixed amounts, percentage of revenue, growth rates, or per-headcount methods, summed into a budgeted P&L by period. - Cash Reconciliation: Verifies the budget keeps projected cash above the minimum-cash balance every period and surfaces infeasible plans with trade-off options. - Variance Tracking: Computes budget-versus-actual variances in dollars and percentages, classifies them as on-plan, warning, or critical, and distinguishes timing differences from run-rate changes. - Use Case: A founder asks for a quarterly FY2027 budget funding a Q2 sales hire and a Q3 marketing push while keeping at least $50k cash; the Skill drafts the budget, flags a Q3 cash-cushion breach, and recommends shifting spend to Q4. ## Quick Start Build my quarterly operating budget for next year from the current forecast, fund my hiring and marketing goals, and keep at least $50k cash in every period.

FAQPage Schema
How do I build an operating budget from a financial forecast?▼

Provide the base forecast, founder goals, and cash constraint, and the Skill builds each budget line using fixed, percentage-of-revenue, growth, or per-headcount methods. It sums lines into a budgeted P&L by period and reconciles the plan against your minimum-cash balance.

How to track actual spending vs budget with variance analysis?▼

Use track_variance mode with period actuals to compute dollar and percentage variances per line and year-to-date. Each variance is classified as on-plan, favorable, warning, or critical, and labeled as a timing difference or a run-rate change.

What happens if my budget exceeds available cash?▼

The Skill flags the budget as infeasible when projected cash drops below the minimum-cash balance in any period. It surfaces the shortfall with trade-off options such as trimming discretionary spend, shifting timing, or founder-approved financing.

When should I use scenario analysis instead of budget building?▼

Use scenario-and-sensitivity-analysis when stress-testing the plan under downside assumptions rather than building the operating budget itself. For near-term cash-out risk, use cash-runway-monitor instead.

Can the budget builder approve spending automatically?▼

No. The Skill drafts budgets and tracks variances but never commits funds. Approving the budget as binding spend authority, authorizing specific spend or hires, and arranging financing all require founder approval.
