A customer already exists with this name and phone
This article will take you through how to resolve app payment issues: A customer already exists with this name and phone.
This error occurs when the POS system detects duplicate account information, such as the same name and phone number, associated with multiple records. It prevents the system from processing payments properly, often causing a delay in service or a failed transaction.
To resolve this issue, remove the customer from the POS system. The account will automatically be recreated when they place their next order.
