The HaveAByte AyaNova hosting rate is $15 per month per scheduleable user, with a minimum of $100/month. It doesn’t matter which version you’re on, which options you have, or add-ons you have purchased, which parts you use, or don’t use. There is also a one-time setup fee of $299. That’s it!
Of course hosting an AyaNova installation for you requires a valid license from Ayanova. AyaNova has changed to a subscription model for support and updates as of May 2016. Subscription licensing costs are here: http://www.ayanova.com/purchase_AyaNova_online.htm
