Online Accounting and Zoho Invoice

Will Zoho Invoice be developed into a Zoho Online Accounting system for small businesses? It seems to me that this is the next logical step in the evolution of Zoho Invoice. Also I'm surprised that Zoho has not developed a Accounts Payable module with bill and bill payment features as the flip side of customers invoicing as a 1st step in this direction. What do you think? Can anyone from Zoho comment on this?
