Use a Free Subdomain with Square Online
About free subdomains
If you don't already own a custom domain and aren't ready to buy one, you can create a free subdomain ending with square.site (like "mybusiness.square.site") for your Square Online site. Using a free subdomain helps with getting you up and running quickly while you continue creating your website and building your brand.
Before you begin
When you first set up your Square Online site, you automatically get a free subdomain based on your business information. If you prefer creating a custom subdomain (like "store.mybusiness.com"), learn how to use a custom subdomain with Square Online.
