Billable 1.1
Clickable Bliss recently took the wraps off of Billable 1.1, a nice update to their billable hours tracking app. New in this update:
Tax support (both US and International)
Custom Invoice numbering
New footer area for customizable notes
Many bugs smashed
There is even a nice screencast that walks you through all the new features (something I wish more developers would do). All in all, not a bad update at all. Billable costs $24.95, and there is a 30 day full feature demo available.
