The account books of nail shops should be filled with customer information, including customer name, contact information, appointment time, etc., so as to facilitate follow-up and contact. Next, list the service items selected by each customer, such as manicure, nail polish painting and manicure design. For each service item, the expense details should be recorded in detail, including the unit price, quantity and subtotal amount of the item. Finally, record the customer's payment methods, such as cash, credit card or mobile payment. Such an account book could have helped the nail salon to manage the customer information, service items and financial situation, which is convenient for future review and statistics.
