Decimo Decimal Discounts sets the percentage value of discounts that already exist in your store to any decimal number, such as 11.5 percent, which the admin cannot accept on its own.
Getting started
-
1
Create a percentage discount in Shopify
This app edits discounts — it does not create them. In Shopify Admin go to Discounts → Create discount, choose either "Amount off products" or "Amount off order", and set the value type to Percentage. Any starting value is fine; you will change it here.
Only percentage discounts appear in this app. Fixed-amount, free-shipping and Buy X Get Y discounts are not shown.

2
Open the Discounts page
Your percentage discounts are listed with their current value. The list is pulled from Shopify each time you open the page. If you just created a discount and do not see it, press Refresh.
-
3
Set a decimal value
Press Edit on a discount, type the exact value you want — for example 11.5 or 7.25 — and press Update Discount. Anything from 0.01% to 99.99% with up to two decimal places is allowed.
A live preview shows the change before you save, e.g. "Will change from 10.00% → 11.50%".

Change many at once (Pro)
On the Discounts page, tick the discounts you want, type one value in the bar that appears at the bottom, and press Update all. A summary shows how many were updated, how many were already at that value, and any that failed.
Select-all ticks the discounts on the current page. Move to the next page and tick again to include those too.

Confirm it took effect
The new value appears in Shopify Admin immediately and applies at checkout on the next order. Every change is recorded on the Activity Log page with the old value, the new value and the time.
Common questions
Why can I not set a decimal value in Shopify Admin?
Shopify Admin rounds percentage discounts to whole numbers. The underlying API accepts decimals, which is exactly what this app uses — so a value like 11.5% is stored and honoured at checkout, it simply cannot be typed in Admin.
A discount I created in Shopify is missing from the list.
Press Refresh on the Discounts page. If it still does not appear, check that it is a percentage discount — fixed-amount, free-shipping and Buy X Get Y discounts are outside this app's scope.
Why is my new discount not in the Activity Log?
The Activity Log records only the changes you make through this app. Discounts created or edited directly in Shopify Admin are not listed there. Use the Discounts page to see everything.
What happens when I reach the free limit?
On the Free plan you get a set number of edits each calendar month. Once used up, the Update button is disabled until the next month, or until you upgrade. Reading your discounts is never limited.
Does a failed edit use up one of my edits?
No. Only successful changes count towards your monthly total.
It says my session expired or asks me to reconnect.
Close the app and reopen it from Shopify Admin. If you are asked to reconnect, press the button and approve the permissions — this app needs read and write access to your discounts and nothing else.
