If you have a SuiteCommerce website, then you will also need to set up your website for multiple languages.
First, you’ll need to update your website settings. Navigate to Commerce > Websites > Website List, and select Edit next to the website you wish to configure for foreign languages. After you choose which languages this website should use, you’ll also want to create a domain name for this website in each of the supported languages. You can add a new domain name to your account at Commerce > Hosting > Domains > New.
Once you have language-specific domains for your website, you’ll need to connect each domain to a specific locale code. When someone accesses the website from a specific location, NetSuite will know based on the associated locale code to display the correct foreign language. You can set this up at Commerce > Web Sites > Configuration.
And finally, you’ll need to update all your landing pages with the correct translation, which you can do either via a CSV import or by using Site Management Tools.
