A business' cash flow is the amount of money moving in and out of a company. A cash flow audit is simply a review of your cash inflows and outflows to help you better understand your finances. Not only does auditing ensure accuracy, but it acts as a cash flow analysis to help your company stay financially health. Additionally, this tool can help you identify areas to improve your cash flow, such as encouraging your customers to pay sooner to reduce the number of outstanding invoices you have or paying your vendors slower to keep more cash on hand to pay your most urgent expenses.
