The AR to Ap Ratio is a key business metric used to analyze the performance of a company’s Accounts Receivable and Accounts Payable departments. This ratio is calculated by taking the current balance in accounts receivable divided by the average balance for accounts payable for a specific period of time. A higher AR to Ap Ratio indicates that the company is more effective at collecting payments from customers, while a lower ratio suggests that the company is having difficulty collecting payments. By monitoring and evaluating this ratio on a regular basis, companies can make insightful decisions about their cash flow and manage their accounts receivable and payable departments more effectively.
