Why does it display “You cannot add items to this order because it contains an item with a fixed selling plan.” when I try to update my customer's pre-order, and how can I edit this?
If a customer wants to change the variant of a pre-ordered item (e.g. switch to a different size or color), you might run into an issue where Shopify prevents order edits due to the "selling plan" attached to the pre-order:
"You cannot add items to this order because it contains an item with a fixed selling plan."
This is a Shopify limitation, but there’s a workaround that may help.
How to edit a pre-order if a customer needs a different variant
- Go to Orders in your Shopify Admin.
- Open the customer's order and remove the pre-ordered item from the order.
- Save the changes.
- Once the pre-order item is removed, Shopify will allow you to edit the order.
- Add the correct variant (or any other necessary changes).
- Save the order with the new variant added.
- Inform the customer about the change.
Important notes
- The new item you add won't be recognized as a pre-order by Shopify or Early Bird.
- Deferred payments and fulfillment dates from the original pre-order will not apply to the newly added item.
- Early Bird reporting will not track the new variant as part of the original pre-order campaign.
- If the change impacts fulfillment timing, be sure to notify your customer accordingly.
