How can I find out credit days of customers for the overdue amounts?

To find out the credit days of customers for overdue amounts, you can start by reviewing your company's credit policy, which typically outlines the standard payment terms offered to customers. Next, check your accounting or invoicing software for records of invoices issued, their due dates, and any payments received. Additionally, consider reaching out to your accounts receivable department for insights into customer payment behaviors and historical data. Finally, analyzing aging reports can help identify patterns in overdue payments and assess the average credit days for each customer.
