Thank you for contacting us.
I noticed you said you were updating these sites using one instance of Sitefinity, so it sounds like you have one site with several domain aliases. Am I correct? In this scenario, you would only need one Sitefinity Standard Edition license. We would also have you sign an annex to the Sitefinity license agreement stating that these are domain aliases and not separate websites.
Our license policy for the Standard Edition is simple to follow. Our license policy for Sitefinity is per domain for $899. You can use the license on an unlimited number of sub domains, servers, machines and developers. The license also comes with 1 year of our subscription package, guaranteeing a 2 business day turnaround on technical inquiries via our support ticket system. The subscription also comes with major and minor upgrades for 1 year. Renewing the subscription is 30% of the cost of the license, which is $270.

Regardless of how many servers you use or whether the websites are part of one company, if these websites are five totally different sites (i.e. yahoo.com, google.com, telerik.com, microsoft.com, facebook.com), you would need five licenses for these five domains. As an alternative, you could assign sub-domains to these sites and these would be complimentary because Sitefinity only regulates the top level domain.
I hope that I have clarified our license policy for you. We would be happy to answer any other sales or licensing questions that you might have. Please e-mail us at email@example.com and a member of our team shall give you online ordering instructions, a quote for PO purposes, or answer additional inquiries.
All the best,
the Telerik team
