The document discusses various types of budgets including master budgets, operating budgets, financial budgets, sales budgets, cash budgets, flexible budgets, and activity-based budgets. It explains that a master budget includes all other financial budgets as well as a budgeted income statement and balance sheet. Operating budgets show projected revenue and expenses, while financial budgets project short-term and long-term incomes and outflows. Sales budgets are important as all other budgets are based on the sales budget. Cash budgets can protect companies from cash flow issues. Flexible budgets show costs for varying activity levels and can be constructed for actual activity levels for control purposes. Activity-based budgets determine resources needed to create output by working backward from activities and their drivers.
