Each Contact has their own unique login for the Online Ordering site
The Email Address you set up is the address they will use to login. They can choose to create a password for themselves on the Online Ordering site or you can set a password for them.
The Contact Notes are very helpful for relationship building by recording small pieces of information you pick up in conversation. For example, if one of your Contacts is a big Green Bay Packers fan, you can note this down and this helps you pick up the conversation with the Contact on the next occasion you speak.
If you have enabled tokenized pre-authorization with either Authorize.Net, the your Contacts will be able to save their card details for future orders. You will also be able to manage those cards in the Back Office (i.e. delete card, save new card, etc). Card details are stored securely on Spoonfed and only the last 4 digits can be viewed by Users.
