Automated Invoices

How can I automate my invoices after orders are placed by either having a link to the invoice from my website made available to my customers, having the invoice automatically emailed to them, or both? Right now, I manually create invoices per order. It would be much easier if invoices were somehow automated similar when one purchases a product from Amazon or other sites. Thanks.

 

You can start automated invoices by using clickbank.

 

Thank you. I am in the process of contacting them for more info.
