• If you only want to preorder when the product is in stock, and end preorder when the product is out of stock -> select Stock is greater than 0 and End pre-order when stock reaches 0

End Pre-order by quantity sold:

• For a profile applied to special products, we count units sold for each product variant, so you can set a limit on the number of units sold for the product variant.

• When a product has reached the limit, it will stop preordering for this product.

• If a product ends by limit and the general configuration of the profile has not expired the preorder period, the product status will change to coming soon preorder.

How to set the Limit Quantity vs End quantity fields?

The values depend on the current inventory level of the product, not just the incoming stock. First, you need to check: What is the current stock quantity of the product right now?

Case 1: Current Stock = 0

If the product currently has 0 inventory and you are expecting 20 units, then:

• Limit quantity = 20

• End quantity = -20

This means the app allows selling up to 20 units in total.

Case 2: Current Stock is NOT 0

For example, if the current stock is 5 and you are expecting 20 more units.

In this case:

• Limit quantity = 20

• End quantity = current stock − expected incoming stock

• End quantity = 5 − 20 = -15

General Formula

• Limit quantity = total number of units you want to sell (existing stock + incoming stock)

• End quantity = current stock − incoming stock

Continue Selling When Out of Stock Option

• Enabled – When a product is out of stock, this option keeps the pre-order available.

• Disabled – When the stock limit is reached, pre-order will automatically stop.

You can display the Pre-order button when the Shopify option Continue selling when out of stock is enabled. Only when the product is enabled with this option, Pre-order will work.
