Benefits

Better order management

Sell Individually allows your store to restrict checkout to one product per order.

Better order fulfillment

If your business sells products that needs to be prepared or manufactured before delivery, restricting the number of products purchased can help you process the orders efficiently.

How does it work?

Display error message

A user has a product in their cart and tries to add another product.

The following error messages will be displayed based on the use case,

• Only one product can be purchased in an order.
• You cannot add this product to the cart because your cart already contains a Product that needs to be purchased separately.

Remove the existing product and add a new product to the cart

A user has a product in their cart and tries to add another product. The existing product in the cart will be removed, and the new product will be added to the cart.
