The One Step Checkout module Nulled is a must-have module that simplifies the checkout process and makes it much easier and faster for customers to buy products at your store.
Responsive One Page Checkout removes unnecessary steps and makes the checkout process much simpler. It provides a nice checkout experience for the customers and greatly increases your website sales. The default and standard checkout that comes with Prestashop includes several “continue” actions required by the customer, this makes checkout very cumbersome and may lead to shopping cart abandonment. This checkout module has been implemented in thousands of web sites and our clients enjoyed the benefits with increased sales. The extension supports Multi language and it is Mobile Responsive and Ajax based.
