I have requested a Zoho Invoice iPad app several times and have been told it is on the list. In the meantime, I was directed to start using mobile.zoho.com on the iPad if I was not satisfied with using the iPhone app. This version looks great but LACKS several functions that are necessary to make it useful. At the very least, the mobile.zoho.com site needs to have the same functionality as the Zoho Invoice app for the iPhone. The most important function that needs to be addressed is the ability to sort invoices by: Unpaid, Overdue and Closed. It would also be nice to have reporting capabilities on mobile.zoho.com/invoice also.
Thanks!
