If you sell goods in Doudian and the payment is slow, you can take the following methods to solve it:

1. Check the order status: Check the order status in the Doudian background to confirm whether there are any orders that have not been paid, or whether there are refunds or other situations that cause payment delays.

2. Contact customer service: If there is a delay in payment, you can contact Doudian customer service to obtain relevant information about the payment progress through online customer service or by calling Doudian customer service hotline. Sometimes, the payment time is delayed for various reasons, and you can get the accurate status by contacting customer service.

3. Verify the payment account information: Ensure the accuracy of the payment account information. If the payment account information such as bank account and Alipay is wrong or incomplete, it may affect the payment efficiency of Doudian. Checking and ensuring the accuracy of account information can reduce the payment delay caused by account errors.

4. Set a reasonable delivery time: Processing orders and shipping as quickly as possible can speed up the payment collection of Doudian after the buyer confirms receipt, and at the same time improve the buyer's satisfaction.

5. Pay attention to account turnover: Regularly monitor the turnover of Doudian accounts and check whether there are undelivered orders and refunds.

In short, if Doudian is slow to return funds, you need to carefully verify the reasons, contact customer service, check account information, properly handle orders, and regularly monitor account turnover to ensure the accuracy and timeliness of the return. If the problem continues, you can also consider upgrading to a merchant level to enjoy more Doudian customer service support services and improve operating efficiency.
