This post will show how to implement some javascript snippets to improve your store conversion with our One Page Checkout:

  • Field reduction
  • Sidebar messages
  • Order reservation countdown timer

Then go inside Shopify admin to section Settings->Files and upload the file. Copy the file url, then go to Apps->One Page Checkout and paste the file location to field Custom javascript file and click Save settings button.
