Hello there!

I am trying to figure out a way to handle One-Time customers without having to create multiple accounts for every single one on Zoho Books.

I understand that I can create a placeholder account called "Walk-In Customer", for example, but I actually need to retain the information of every customer, as in I need to have their phone numbers saved in case a mistake happens, and I need to call them. 

From my understanding and experience, this information could go away if I make the "Walk-In Customer" account.

Does anyone know how I can manage this properly?

Any help is always appreciated.
