A company called Fi-Span (in Vancouver) is building a suiteapp that will integrate seamlessly with most of the financial institutions. It will send payments to vendor and receive realtime status notification from the bank. Couple of weeks ago I had a demo of the product (beta) so I can give them feedback and suggestions. I have been an outside adviser and enduser feedback for this solution. This payment solution is robust and solve all the problem now a days we have for procure to pay. As far as I know few NS clients are using it as beta. http://www.fispan.com/
