Thanks Miriam for mentioning the what happens when cancelling Yext article that Nyagoslav Zhekov has done really good research for us here, even though Yext states that they do not remove listings after cancellation.
Like Miriam said there are ways of going around Yext, but some have switched over to Yext empire including Local.com, and American Towns. Not sure of your specific industry but these directories are generally not in the top 10 most important listings so some of us choose to go for the main listings manually and add others as needed per industry.
As for enterprise account I was able find info in a $149 a year re-seller account that gives you 5% off for your clients: http://www.yext.com/pl/reseller-scanning/resellers-faq.html
