Checkout+ is a consumer-paid returns model designed to benefit both merchants and shoppers. Merchants can eliminate the burden of return expenses while shoppers can unlock free returns by paying a small fee at checkout.

Before following the steps below, the merchant should confirm with their Merchant Success Manager that they're a Checkout+ customer.

1. In the Shopify admin, navigate to Sales channels → Online Store → Themes.

2. Find the theme to use for the want to edit, and then click Customize.

3. On the sidebar, click the App embeds icon.

4. Click the toggle button next to Loop Storefront.

   

5. Turn on the Checkout+ Integration toggle to active Checkout+

   

6. Click Save.

When going through the checkout process, Shopify will now replace the default checkout buttons with the Checkout+ button in both the cart and cart page.

How to set up Checkout+ in Checkout:

   • Include app block in Shop Pay - This allows the app block to be visible when using Shop Pay. Tip: Loop recommends turning this on!

7. Optionally, click the Preview Shop Pay link to see a preview of how the Checkout App Block will appear in Shop Pay.

To ensure the Checkout+ product can only be purchased one time per order, please setup the following in your Shopify settings:

1. Settings > Checkout > Scroll to 'Checkout rules'

   

2. Add Rule > Checkout Plus Cart Quantity Validator

   

3. Save > Turn On

   

4. Ensure your Checkout+ product has the following Product Tag in Shopify: checkout-plus-limit-quantity

   

5. Test to validate this is working properly by attempting to add multiple Checkout+ products to your cart

   

How do I know if I'm eligible to set up Checkout+? Before attempting to set up Checkout+, please confirm with your Merchant Success Manager that you're a Checkout+ customer. They will be able to verify your eligibility and provide any necessary guidance.

Does this setup work with third party carts such as Upcart and Aftersell? Yes, most of the time it will. However, if it doesn't, contact Loop support—we can manually add the Checkout+ buttons to your cart in order to complete setup.
