What does the In-Store Credit Card Processing for a Pressero account include?

As of 2017, secure certificates can be enabled on any Pressero site in the Settings > Domains window and installed automatically for any site at no extra cost, they are included with your subscription. Any old certificate ordering information no longer applies. The site address must direct to Pressero on DNS, and the certificate process can take up to 24-48 hours to complete getting a certificate for your site address, but usually will complete in a few hours or less.
Please check the article What do I do when I'm ready to "go live" with my Pressero site? for the DNS pointer values you will need to point your domain address or subdomain address to Pressero, so that Pressero will be able to serve the site to those requests after the address is entered in Ch. 034 Domains Tab in Settings
