Budgetary control is the process of comparing actual results to planned budgets in order to calculate variances and ensure maximum profitability. It involves preparing budgets, coordinating departments, and acting on performance results. A budget officer coordinates budgets across departments and informs management of deviations. Budget committees include department heads and are responsible for budget preparation and execution. Key factors that influence other budgets, like sales quantities, are identified. Budgetary control aims to maximize profits through planning, coordination, accountability, and correction of weaknesses.
