How to enter customer information in the anti-counterfeiting invoicing system?

The entry can generally be done in advance (when the company adds new customer records) or during the process (when there is new company invoicing information)

The entry is in the system settings - customers During coding, it is recommended that the customer's code be set to a tax number or entered in the form of a first-level code (XX) or a second-level code (XX) XXX. The former is easy to ensure the uniqueness of the code, and the latter is easy to manage and search

Finally, I suggest you also enter the shortcode and use the slogan for invoicing
