SagePay VSP (formerly Protx) Payment types - Deferred Payment and Authenticate
There are two alternative payment types available to merchants to replace Pre-Auth:
Deferred Payment or Authenticate and Authorise. Both of these systems allow you to accept an order, but not take payment until you are ready to ship the goods. Both of these systems provide significant benefits over the old system. These payment options are explained in more detail below.
As a rule, if you know the exact value of the transaction at the time of order placement and you are able to settle that payment within 6 days of placing the order, Deferred Payment is the best system for you to use.
If you wish to delay the payment for longer than 6 days or if you do not know the exact price at the time the order is placed, Authenticate and Authorise is the best option for you
In ShopFactory to accept Payment Type "AUTHENTICATE" use "AUTH" before your SagePay Vendor username.
In ShopFactory to accept Payment Type "DEFERRED"
use "DEFERRED" before your SagePay Vendor Username
