Can’t add product to cart on Shopify (Variant doesn’t exist)

Last updated: April 27, 2026

What you’ll see

When trying to add a product created with Customily to the cart, you get an error like:

  • “This variant doesn’t exist”

  • “Variant is unavailable”

  • Or the Add to Cart button doesn’t work.

Why this happens

This usually means Shopify can’t find a valid, available variant for the product.

How to fix it

1. Make sure the product is active

  • Go to your product in Shopify

  • Check that it is not set to Draft

👉 Many themes don’t allow adding draft products to the cart.

2. Check the product is available on your storefront

  • In the product settings on Shopify, look for Sales channels and apps

  • Make sure your Online Store channel is selected

3. Check inventory settings

  • Open your product variants

  • If Track quantity is enabled:

    • Make sure the variant has stock available

  • If you don’t need inventory tracking:

    • Disable Track quantity

4. Check shipping setup

If the product still appears as sold out or unavailable, it may not have valid shipping rates.

  • When publishing from Customily, the product is assigned to the Customily location

  • This location must have a shipping profile with valid rates

👉 If the Customily location is not included in a shipping profile, Shopify may treat the product as unavailable.

How to check:

  • Go to Settings → Shipping and delivery in Shopify

  • Open your shipping profiles

  • Make sure the Customily location is included and has rates assigned
