You can control how stock is displayed and when the pre-order button appears by choosing the right inventory setting in PreOrder Now.
This guide explains what each option does and how to use them correctly.
Overview of Inventory Options
There are two inventory options available, and each controls how your product behaves when stock changes:
Inventory Option 1
Does not display stock levels through the app
Does not show a stock warning in PreOrder Now
Your theme usually handles stock display already
👉 Use this option if you only want standard in-stock behavior without pre-orders.
Inventory Option 2
Automatically switches to a “Pre-order” button when a product is out of stock
Allows you to set how many units can be pre-ordered
Can display available pre-order stock to customers
👉 This is the option to use if you want to enable pre-orders.
Showing Available Stock
We only display stock in one specific case:
When using “Specify inventory available to pre-order”
If enabled:
Customers will see how many units are available for pre-order directly on the product page
This helps set expectations and reduce confusion
Pre-order Behavior
To enable automatic pre-orders:
Set your inventory to Option 2
Once the product reaches zero stock:
The Add to Cart button switches to Pre-order
Customers can continue purchasing based on your configured pre-order limit
Important Notes About Stock Warning Settings
There are a couple of important limitations to be aware of:
🚫 Not Supported
Stock Warning (showing remaining stock) is not provided by the app under Option 1
→ Most themes already handle this nativelyPrevent Customers from Ordering More than the Preorder Stock Available
→ This setting is currently not working as expected
✅ Recommended / Expected Behavior
The “Prevent overselling” behavior should apply when using:
Specify inventory available to pre-order
The following setting should be used with Option 2:
Notify Customers When Part of Their Order Will Be on Pre-order
This helps customers clearly understand when part of their order isn’t immediately available.
