Advanced Domain Setup
The simplest way to set up an online store in NetSuite is to create a Single Domain for Web Store and Checkout domain and secure it using an automatic certificate. This keeps both shopping and checkout activities on the same domain making it faster and more efficient. Such a domain is also easier to maintain as automatic certification means that Oracle NetSuite take care of the process of certificate renewal on your behalf.
However, in some cases, you may prefer to keep the web store and checkout on different domains. For details on how this setup works, see Web Store Sessions.
You may also prefer to obtain a certificate from your preferred certificate authority. For details on how to do this, see Manual Certificates.
