What licence to use for multiple users on one website?

Hi! I’m thinking of buying one of the web page templates. I want to create a web page on which I will have multiple users, and they will be charged for usage of the site.
Would this still qualify as a single end product, since it would be a single website, or would I need to buy a licence for every user of the website?

Single license will be fine for the website because it is a single end product. Thanks
