Dear [Customer's Name], We hope this letter finds you well. We would like to inform you of an important change regarding your credit status with our company. After careful consideration, we have decided to convert your account's credit limit to C.O.D. (Cash on Delivery) status. This decision was made based on the history of your payment habits and the current economic environment. As a responsible business, we strive to maintain a healthy cash flow and minimize financial risks. By shifting to a C.O.D. basis, we aim to ensure timely and secure payments for our products and services. Please note that this change will be effective starting [date]. Consequently, upon placement of an order, we kindly request that all payments be made in full at the time of delivery. Our delivery personnel will no longer be able to process orders without immediate payment. We understand that this adjustment may cause some inconvenience, but we assure you that it is essential for us to continue providing you with the high-quality products and services you expect. It is our priority to maintain a mutually beneficial relationship, and we believe this alteration will promote transparency and fairness in our business interactions. We appreciate your understanding and cooperation during this transition. As always, we remain committed to serving you and meeting your needs. Should you have any questions or concerns, please do not hesitate to reach out to our customer service team at [phone number] or [email address]. We will be more than happy to assist you. Thank you for your support and continued partnership. Sincerely, [Your Name] [Your Title] [Company Name] [Address] [City, State, ZIP Code]
