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.
