Accounting Ideas

I would like to be able to send invoice and mark invoices as paid directly from the app as I rarely get a chance to sit down in front of the computer. I run a mobile business so am often on the road without wifi conncetions not to mentio the time it takes to load up a computer to create and send the invoices. Other accounting apps will send the invoice directly from my phone once the invoice is made up. I would like to see the same with this as I find the desktop version very good compared to other programs.
