For many reasons, website owners feel the need to have a purchase only process after you have approved it. Follow along to see how this is done.
Begin by navigating to SYSTEM > CONFIGURATION
From here use the left-hand navigation and navigate to SALES > PAYMENT METHODS
Once here select the AUTHORIZE.NET drop-down.
You use the section titled Payment Action. It only allows two options Authorize only and Authorize and Capture.
Authorize and Capture - This will allow all website purchases to be handled automatically.
Authorize Only - This will prevent the purchase to be processed until you have validated and approved said purchase.
Once complete, click SAVE CONFIG in the top right corner.
Once an order has come in, navigate to SALES > ORDERS.
Click on or search for the said order.
If the order seems right to you, approve and finalize the order by clicking INVOICE.
And now the order has been fully processed.
You can change any of these options back at anytime.
