This module solves one of the biggest problems that online sales have: low conversion rates, very few of your visits end up buying in your store. All these aspects undermine the overall performance of your online store, the worst of all is that many times is something that goes unnoticed.
With this module we propose to simplify your sales process so that your customers can do it in a single page avoiding cumbersome registration forms to complete the sale, endless validations, excessive purchase steps (registration, shipping, payment, confirmation, etc.) . Now making a purchase will become an easy, friendly and simple process, where your customers can see the shipping costs if you need to register, a summary of the cart in which to modify the quantities without having to reload the page.
