Google Checkout: Best Practices for Merchant Payments

[mandy]

I'd like to share a few best practices we've been seeing that may help you be even more successful. Here it goes:

1. Charge orders within 72 hours
When a buyer confirms a purchase, you'll receive an order, and Google performs the authorization for 100% of the order amount. Then you must charge the order within 72 hours (that's 3 days) to be guaranteed the funds. More details are here.

2. Be sure to get the order and risk info before shipping
We strongly recommend that you don't ship an order until you've received the new order notification and risk assessment. Both of these notifications are critical to accurately evaluate each order's risk level - and we believe that merchants who review both prior to shipping will see more successful transactions.

3. Watch for cancelled orders...
4.  Support buyer inquiries...
5. Train your customer support staff...
