According to the manual:
Difference between a customer name and a contact name
A customer name is the name of the organisation and a contact name is the name of the user who is operating the ERPNext system.
For Example: If American Power Mills is an organisation name and their founder Shiv Agarwal has installed ERPNext on his system. Then,
Customer Name: American Power Mills
Contact Name: Shiv Agarwal
Well in my case, most of the customers are individual, only a few are corporate customers. How to solve this?
