Checkout Options

 Pick the page which users will go to when they click the 'Continue Shopping' button.  You should be consistent as this option occurs in multiple modules.  The user should always end up where they expected.

You can set up whatever format you need for Order Numbers.  However, OctEportal uses a monotonically incrementing number (We increase it by one each time! And we don't go back to fill in any gaps)

You should always confirm to your customer that they have placed an order.  The Payment Service Provider may do the same, but you cannot guarantee this.  It is also good PR.

The email message can include any of the 'tokens' shown in the list.  Remember to include the [Square Brackets]!

Complete only if you are VAT registered 

If you are using Sales Vouchers as a marketing or credit tool then check the box.  The other options affect the way that the Checkout appears.

See the Payment Service Providers page for more information
