This should be a wonderful web based application to manage/track customer requests. Customer information, custom plans and support request tracker are available. Searching is there by various parameters. Advance searching feature will be added soon.
If you are in a need for a tool to track/manage your customer requests then this would be a better tool for you. There are many changes/improvements need to be and will be done. So help me find the requirements that will satisfy your/majority of the companies.
