Days Outstanding In Accounts Receivable (DOAAR) is a measure of how long it takes a customer to pay off their debt. It is calculated by dividing the total amount of outstanding invoices in a given period by the average daily sales during that same period. The DOAAR metric helps businesses understand how quickly they can expect to receive payments from customers, allowing them to better manage cash flow and make informed decisions about funding. Knowing this metric can help businesses maintain healthy accounts receivable and successfully manage their financial operations.
