From time to time, you probably do work for clients that are billed at a flat rate, rather than hourly. Bill4Time can help!
Blackberry, iPhone, Treo, PocketPC, and Smartphone users can install Bill4Time Mobile on your wireless handheld and enter time and expenses while on-the-go. There is no need to ever physically "sync" the PDA to your computer as all entries are wirelessly uploaded to the Bill4Time servers in real-time. Your entries will be immediately available in reports and ready for billing. You can also look up client balances and payment information right from your mobile device.
