Overheads aren’t typically a place where you will find a lot of waste. Our experience is that business owners are very careful about managing their expenses, and the smaller the business, the truer that statement is.
Having said that, as a business grows, so do the layers of hierarchy. Management control can deteriorate, and the business can become a bit flabby. The trick is to trim the fat but not the muscle when evaluating your expenses.
As an absolute minimum, every business should do a thorough review of its overheads at the same time every year, so that it becomes a natural routine.
