Best project tracking and business CRM

I just love it! My team and I use the free version and it is so robust. We love the ability to track and provide status reports on tasks. The integration of CRM tracking is just an added benefit. However with all free versions there are some struggles. Would love better ways to manage files and documents. Retrieval is time consuming. Also using the project management and workflow section are clumsy. But hey, if it were perfect who would buy it. For small 1-5 teams its great.
