Now, you do not need to abandon your Cart to create a new Customer. You can add a new Customer while you are on your Cart page!
Here is how you can do that:
A list of all your existing customers will appear. To add a new customer, tap on the New button on the page. You will be able to fill in all you customer details here.
When you are ready, click "Save" and a new customer will be created and added to the Order. Remember if you are writing an order quickly, Name, Address Label and Address Line 1 are the required fields.
The next time you create an order you will be able to select this customer from your list of existing customers. Simply tap on "Choose Customer".
