Wrong Discount Price, Price changing automatically

Technical Q&A

Topic summary

A user is experiencing an issue where applying fixed-amount discounts in Shopify Draft Orders causes the original item price to change unexpectedly, resulting in incorrect final amounts.

Example of the problem:

  • Item starts at $100
  • After applying a $25 discount, the item price changes to $115
  • Final price becomes $90 instead of the intended $75

Key details:

  • The price changes to random amounts, not matching the Compare at Price or Original Price fields
  • The issue occurs both when applying discounts and sometimes when converting Draft Orders to Orders
  • Behavior is inconsistent and has happened multiple times

Potential workaround suggested:
One commenter recommends using the “Draft Order Edit” app, which allows setting custom pricing directly on products/variants without relying on the discount system.

The root cause remains unidentified, and the user seeks either a fix or the ability to manually set final discounted prices per item.

I have a problem when I try to apply a fixed amount discount in the Draft Order. The original price of the item just changes after I apply a set amount of discount causing the final amount to be incorrect. I remove the discount and re apply a different fixed amount and the original price would change again causing the final amount to be wrong again. Sometimes, everything looks good in the Draft Order and when I convert it to an Order, the original price will change again.

Example,

Item Price: $100
Fixed Amount Discount: $25 (I apply)
After I try to apply, the Item price would change to $115, so the Final Price would become $90 instead of the intended $75.

These has happened a couple of times. I was wondering if it’s because of the Compare at Price and the Original Price of the item that is causing the problem but I’ve checked and the changed price is not the Original Price as well, it’s just some random amount in between the prices.

I am hoping there could be an option for me to just put the the final (discounted) amount for each item so I don’t have worry about the original price changing. Please help!

Not entirely sure if this is what you’re after, but with Draft Order Edit, you can have custom pricing on ANY product (or variant) inside your draft order (without needing discounts etc). This means you can make ANY product cheaper or more expensive, depending on the unique order requirements, without needing to worry about discounts.
