Amazon Payments - Checkout by Amazon

Overview

Checkout by Amazon allows your customers to checkout on Amazon.com, using their Amazon.com user account. When a customer clicks the View Cart button in Squirrelcart, your customer will see the following:

If they click the Checkout with Amazon button, they are taken to Amazon.com to complete the entire checkout process.

If you have no other payment methods enabled, they will only see the Checkout with Amazon button.

Important Considerations

Checkout by Amazon is not just a payment processor. They handle the entire checkout experience, including:

Obtaining shipping and billing address information
Totalling items in cart
Adding shipping charges
Adding tax
Obtaining payment
Storing order

Because Amazon is taking over the entire checkout process, the following features/settings in Squirrelcart have no impact on an order placed via Checkout by Amazon:

Inventory Control
Taxes
Shipping rates
Order storage

When an order is placed using Checkout by Amazon, Squirrelcart will not store the order in your database, and will not email the customer or you to indicate an order has been submitted.

If you prefer to allow Squirrelcart to handle the checkout process, along with inventory control, taxes, shipping, and order storage - Amazon Simple Pay is a better alternative.
