Zero Subtotal Checkout

Zero Subtotal Checkout can be used for orders with a subtotal of zero that are taxed after a discount is applied. For example, Zero Subtotal Checkout might be used in the following situations:

• A discount covers the entire price of the purchase, with no additional charge for shipping.

• The customer adds a downloadable or virtual product to the shopping cart, and the price equals zero.

• The price of a simple product is zero, and the Free Shipping method is available.

• A coupon code covers the full price of products and shipping.

To save time, zero subtotal orders can be set to invoice automatically.
