It is the only way critical decisions and corrective actions can be planned and then taken. If the owner-manager is constantly putting out fires, monthly comparisons are not being made nor are timely corrective actions being taken. Corrective action is taken when expenses are over budget. Most small businesses get into financial trouble because they do the right thing too late. Taking timely corrective action is the mark of an effective business owner-manager.
Owner prepares budget.
An excellent budget prepared by an employee or accountant is virtually useless if the owner is not committed to it. Budget preparation educates the owner to the realities of the business. Looking at a budget prepared by another does not educate the viewer. When the owner has someone else prepare the budget, the control of the business has been delegated to that person. The budget is realistic.
