If you would compare close.io in a first instance to other CRM's they would be more expensive. However it is good to know that there are no hidden costs, the platform offers a lot of features and you should be able to generate extra-revenue per user than what you pay extra.
Close.io is build to make it usage as easy as possible for the sales person.
