Getting Started with Fluid Checkout

Fluid Checkout replaces the WooCommerce checkout, cart and order received pages with a consistent and better purchase experience, eliminating unnecessary friction at the most critical step of online sales. See all features on our homepage.

This documentation will guide you through the installation and configuration of Fluid Checkout Lite, Fluid Checkout PRO and other Fluid Checkout add-ons.

Installing Fluid Checkout Lite #

Fluid Checkout Lite is the free version of the plugin, offering essential features to enhance the default WooCommerce checkout experience.

Follow the steps below to install and activate Fluid Checkout Lite:

  1. On your website, go to WP Admin > Plugins > Add New Plugin.
  2. Search for “Fluid Checkout” in the plugin repository.

  2. Then click the button “Activate” to activate the plugin.
  3. Once activated, go to WP Admin > WooCommerce > Settings > Fluid Checkout.
  4. Then go to the sub-tab Checkout to configure the checkout form options.
  5. Click the button “Save changes” at the bottom of the page to save your changes.

Note: At this point your checkout page should be already running on Fluid Checkout. If you do not see any changes to your checkout page after following these steps, you might need to replace the WooCommerce block-based checkout and cart forms with the respective WooCommerce shortcodes on the designated pages on your website.

Manual installation from downloaded zip file #

Alternatively, you can download the latest version of Fluid Checkout Lite from the WordPress.org directory as an installable zip file and manually install it using the plugin upload option on your website admin.

  1. Go to the plugin page on WordPress.org at https://wordpress.org/plugins/fluid-checkout/
  2. Then click the “Download” button on the right part of the page.
  3. Once the download is completed, go to WP Admin > Plugins > Add new on your website.

  9. Then go to the sub-tab “Checkout” to configure the checkout form options.
  10. Click the button “Save changes” at the bottom of the page to save your changes.

Note: At this point your checkout page should be already running on Fluid Checkout. If you do not see any changes to your checkout page after following these steps, you might need to replace the WooCommerce block-based checkout and cart forms with the respective WooCommerce shortcodes on the designated pages on your website.
