The new application will include a server piece (like Daylite), a way to use the application offline and then sync to the server (once again built upon Daylite), over-the-air sync (as with Daylite Touch), and Marketcircle's expertise in desktop and mobile user interfaces.
The application is still in development, and beta testing won't begin for a few months yet. If you're an existing Billings user and would like to receive consideration as a possible beta tester, fill out this online form and you may hear from Marketcircle in a few months.
At this time, no ship date or price has been determined for Billings Pro.
