Basic definition

To add your customers, go to

Sales > Customers > Add new

This will open a new window where you will be able to add all your customers basic information, categories, contact person information etc.

In the 'ship to' line, you can add a different shipping address, if needed.

You can also add a customer when you are creating a new sales order. If you started creating a sales order by going to Sales > Sales Order > Create, and you do not have the customer predefined, you can use the 'quick add' option and define a new customer by typing in only the basic information.

Of course, you can always go back to that particular customer in the customer list (Sales > Customers) and add additional information.
