Hi, @Oz_Barron !
I’m Miles from the Social Care team at Shopify.
At this stage, there is no option to allow overselling as a default setting, however, you are absolutely able to select this option for new and existing products.
For New Products
When creating your product, under inventory, ensure “Track Inventory” is ticked. This is generally ticked by default. Underneath that checkbox, you’ll see another option to “Continue selling when out of stock”. Once this is ticked, the product will be available for overselling when out of stock.
Bulk Updates for Existing Products
For existing products, you’re able to edit them in bulk, so you can make the change once for all existing products. To allow overselling for these products, follow these steps:
- Go to Products > All Products
- Select all products.
- Click “Edit products”.
- Once the spreadsheet opens, click “Add fields” and select “Continue selling when out of stock”.
- Tick the checkboxes for all products you’d like to continue selling when sold out.
We have a great guide around bulk editing that might be useful for you. If you’d like to import or update via products via a CSV, you can also check out this guide.
Have a great day!
