MYOB's monthly subscription invoices - why not in bills

Hi,

I just had to login to my.MYOB to see my MYOB subscription invoices, then download them, to then be able to email them back to bills@MYOB.

This seems very odd, why wouldn't the subscription fees for the software you are using to manage accounts automatically add it's own bill into the system. Or at least have an option to chose to do this.

Regards

Paul
