How to Enable Quick Buy in Shopify Force Theme

Quick buy adds a product straight to the cart from the collection grid — a real time-saver for simple products where a shopper doesn't need the full product page first.

Steps

In your Shopify admin, go to Online Store > Themes and click Customize on Force.
Switch to a Collection template using the page picker.
Select the Product grid section.
Find the Quick buy setting and turn it on.
Click Save.

Quick buy works best on products with no variants, or few enough that a compact inline picker doesn't get cramped — for anything with a lot of variant options, a full quick-view popup is usually the better fit.
