Invoice is not available for CRM mobile APP?

Invoice is not available for CRM mobile APP?

So i was just about to close a deal with a new client who would be using the Zoho CRM mobile application and discovered its missing the invoicing component which is already built-into the desktop CRM application.  

What is the timeline on launching a CRM app for the ipad that mirrors the functionality of what you offer on the desktop version; specifically the invoicing component?
