Description

Upgrade your Zen Cart checkout system with a modern layout and functional process that increases your store's conversion rate. One Page Responsive Checkout is packed with features that improve the usability of the checkout process and make it easier for customers to complete purchases on your website, regardless of their device or browser. The responsive CSS makes the checkout transform the dimensions of your website for the perfect layout—whether your customer is searching on a mobile device, a tablet, a desktop, or even a large screen TV.

Using a One Page Checkout module for eCommerce websites is essential to avoid losing customers throughout the checkout process. As mobile devices become more popular for online shopping, consumers demand simple design. Luckily for your eCommerce store, Numinix has developed this one-page checkout module that requires minimal site changes to implement. One Page Responsive Checkouts provide the speed of one-click checkouts without the risk of increased order cancellations. Instead, eCommerce site owners enjoy a higher conversion rate and lower dropoff rates that are commonly associated with traditional multi-page checkout methods.

    Note: In case the cron scripts take too long to run that cause Timed Out errors in browser (large customers database). Setup the cron to run from command line instead of wget (e.g. on linux web server: /usr/bin/php /home/yourdomain/public_html/store_credit_cron.php)

    $disabled_types = explode(',', MODULE_ORDER_TOTAL_SC_DISABLED_TYPE);

    }
    if (MODULE_ORDER_TOTAL_SC_DISABLED_FOR_WHOLESALE == 'true' && isset($_SESSION['customer_whole']) && $_SESSION['customer_whole'] != 0 && in_array('reward', $disabled_types)) {

Note: If the cron scripts take too long to run and cause timeout errors in the browser (with large customer databases), set up the cron to run from the command line instead of wget (e.g., on a Linux web server: /usr/bin/php /home/yourdomain/public_html/store_credit_cron.php).

FAQs

FAQs

What is the One Page Responsive Checkout module?

The One Page Responsive Checkout is a modern Zen Cart module that streamlines the entire purchase process into a single, user-friendly checkout page where customers can complete billing, shipping, and payment details in one place. By eliminating multi-step navigation, it improves checkout speed, reduces friction and cart abandonment, and enhances the overall shopping experience across desktop, tablet, and mobile devices.

How does this module improve my store’s conversion rate?

A shorter and simpler checkout process makes it easier for customers to complete their purchase. By reducing page loads and unnecessary steps, customers are less likely to abandon their cart. A clear, single-page checkout helps increase completed orders, especially for shoppers on mobile devices.

Is it difficult to install or integrate into my existing Zen Cart setup?

No. The module is built to work with standard Zen Cart installations and follows Zen Cart best practices. It integrates with most common payment and shipping modules and can be configured without the need for custom development.

How is this better than traditional multi-page checkout systems?

Traditional checkout systems require customers to move through several pages to complete an order, which can slow down the process and lead to frustration. A single-page checkout keeps everything visible and easy to follow, allowing customers to complete their purchase more quickly and with fewer interruptions.

Will this work for customers shopping on mobile devices?

Yes. The checkout is fully responsive and adjusts automatically for phones, tablets, and desktop screens. Mobile shoppers can complete their purchase comfortably without zooming, excessive scrolling, or layout issues.

Will implementing this module require major changes to my site?

No. One Page Responsive Checkout is designed to require minimal site changes for implementation. It integrates smoothly with your existing Zen Cart installation.

Does the checkout page reload during the process?

No. The checkout uses Ajax technology, so there are no page reloads. This creates a faster, smoother experience for your customers as they move through the checkout steps.

Can customers log in using their Facebook account?

Yes. The module includes Facebook login integration, making it even easier for customers to complete their purchase quickly.

Does this work with other Zen Cart modules?

Yes. The checkout comes pre-integrated with popular modules like Gift Wrap and PO Box Ban, so you don't need to merge shared files; you can install the modules separately.

Can I track checkout performance in Google Analytics?

Yes. The module includes built-in support for tracking customer checkout steps with Google Analytics, helping you understand and optimize your conversion funnel.

Service Policy

Our stated prices for all modules we install are based on installation into the default platform configuration. We always ensure your logo and basic color palette are in place when we install a plugin. However, any additional "custom" styling, design work, or derivitive tasks generated due to a site's non-default configuration could require additional prepaid programming hours.

This plugin is open source and requires ionCube Loader v4.4 or later to be compiled with PHP in order to install and upgrade the plugin. All orders are automatically subscribed to the billing frequency selected at the time of purchase. Recurring billing can be cancelled at any time. Once your license has expired, a new license will be required in order to continue using the plugin.
