"Communication is important when running a business. One client we helped was not receiving the necessary information from the field. Their work wasn't being scheduled properly, and the company was not reviewing their cash flow or profitability on a consistent basis. After performing an operational review, we recommended that the company properly reconcile their accounting information and improve their reporting. Our team helped the client review their method of collections and implemented new procedures to reduce collection time. We assisted them in implementing incentive compensation programs, which led to increased profitability. We were able to help them consolidate staff duties and reduce their payroll costs. The savings we helped our client realize was quite substantial, and they appreciated that their accountants were able to look beyond the numbers and offer them effective management advice."
