What problem does it solve? Ecommerce operators often manage budgets in disconnected spreadsheets, discover marketing overspend only at month-end, and split annual revenue evenly across months despite heavy seasonality. This Skill provides a structured process for building rolling operating budgets, tracking budget vs. actuals, and alerting on spend pacing before it is too late to act. ## Core Features & Use Cases - Revenue Budgeting with Seasonality: Build channel-level revenue budgets from trailing 12-month actuals using per-channel growth rates and seasonal indices instead of flat monthly splits. - Marketing and Inventory Budgets: Allocate marketing spend as percentage-of-revenue rates per channel with fixed brand costs and seasonal multipliers, plus open-to-buy inventory budgets based on weeks of cover and supplier lead times. - Variance Analysis and Alerts: Produce monthly budget vs. actuals variance reports with materiality thresholds, and mid-month pacing alerts that flag overspend or underspend by department. - Use Case: A finance lead connects Shopify to QuickBooks, builds a 2026 revenue budget weighted toward Q4, sets Meta ads at 12% of website revenue, and receives a critical alert on day 20 when Paid Social pacing hits 2.55x its expected utilization. ## Quick Start Ask the AI to build a 12-month revenue budget for your Shopify store using last year's monthly actuals, 20% growth, and seasonal weights, then generate a budget vs. actuals variance report.
