WDTMonitor is our solution of tracking billing records, including: time, dollar amount, description of work and even client's correspondence for multiple clients or companies. The Application can even be used as private troubleshooting board between freelancer or web developer and its clients. You can give access to client and they can post their responses or comments. We wrote this online application two years ago and are using it since very successfully, keeping billing records of our clients on this server.
At a first step you would have to create Developer Account. Once you are in, create Client, Add Client’s Contacts and default monthly budget for this client and your account is ready. Go ahead, Add Job and start using the application. It should be easy and fan, specially looking at your previous month's postings and correspondence with client in regards of seeing your company growing.
