How to use custom domain names in Jotform?

Can't I use a domain name with my form? I'm using a QR code on a leaflet that opens up a jotform domain which is confusing to my leads. I'm disappointed to not see this as a basic feature as this is a standard feature acorss many other similar platforms such as unbounce.com

So far I can't use a facebook ad pixel and I can't use a domain name.... Jotform seems pretty weak so far. Espcially when I could just code this whole form and feature myself with some basic Javascript and use my domain and a facebook pixel.

Custom domains is an Enterprise feature. It used to be on standard / paid plans, but was moved to Enterprise feature.

That's a load of nonsense. It's a basic feature anyone would expect as standard. So go on then, just to make me laugh... how much is the enterprise plan?
