Wix Stores: Adding and Setting Up the Wix Checkout Requirements App
With the Checkout Requirements app, you can take control over what requirements need to be fulfilled before a customer can complete checkout. You can use the app to create 3 different types of requirements:
Add a minimum quantity of products requirement: Prevent customers from purchasing too few of a specific item (e.g. minimum purchase is 3 vanilla candles). Add a maximum quantity of products requirement: Prevent customers from purchasing too many of a specific item (e.g. Purchase of vases is limited to one per order). Add a minimum order subtotal requirement: Orders must reach a minimum of $100.Check out some examples of how the checkout requirement can be used in the FAQs below.After creating one or more checkout requirements, you can easily activate or deactivate them with a click.Step 1 | Add the Checkout Requirements appTo get started, go to the Wix App Market and add the Checkout Requirements app.Wix EditorEditor XStudio EditorDashboard

Specific products: Only specific product(s) count towards the minimum or maximum (e.g. if you set a 2-product minimum, customers must buy 2 of each of the specific products you select). All products: The requirement applies separately to each product (e.g. if you set a 2-product minimum, customers must buy 2 of each product they buy, not 2 products from your shop).   If you selected Specific products in step 6, select those products.
