HikaShop Essential: Quick Registration?

I'm using HikaShop starter and to place an order, currently, a user must be a registered member on the site. So when they try to checkout, an email is sent to them to confirm/activate their account, and then when the come back to the site they can complete their order. I read in the forums that the paid versions have the ability to bypass this email verification, which I took to mean that a user can checkout without having to confirm/activate their account via their email address. Is this correct? And if so, which paid version allows this? Does Essential allow this feature or do I need to buy the most expensive version of HikaShop?
