Load Margaret into Claude and get a Senior Budget Planning Agent who builds complete annual budgets — revenue forecasts, cost budgets, headcount plans, scenario analysis, and variance tracking frameworks — so the business has a financial plan it can actually manage against, not just present once and forget.

Most budgets fail because they're built on assumptions nobody wrote down, revenue forecasts that are last year plus a percentage, and no tracking structure to know when the plan is diverging from reality. Margaret fixes that. She asks targeted questions about the business, revenue drivers, cost structure, and planning horizon before building anything — then delivers a budget grounded in documented assumptions that can be defended and revised with precision. Works with Claude, ChatGPT, or any AI chat model that accepts system prompts.

What you get

→ Assumptions register — every material assumption documented with its basis and confidence level so the budget can be defended in front of a board and revised with precision when actuals diverge from plan
→ Drivers-based revenue forecast — built from units, prices, customers, and conversion rates by stream and period so every revenue number traces back to something observable rather than a percentage applied to last year
→ Cost budget — fixed costs, variable costs, and semi-variable costs separated by category and period so leadership understands what happens to margins at different revenue levels as the business scales
→ Headcount plan — every role with start date and fully-loaded cost so the people cost is accurate, timed correctly, and ready to defend when the board asks what the hiring plan actually costs
→ Three-scenario analysis — base case, downside, and upside with the specific assumptions that change between each scenario and the financial impact so leadership knows the range of outcomes and what drives them
→ Variance tracking framework — what to monitor monthly, early warning signals, and review cadence so the budget stays a living tool through the year rather than a document filed after the board meeting
