Colubris helps small creative teams track projects and clients. It focuses on Budgets, agreements between your team and your client to pay you money for your work. It helps your developer or design team focus on projects which are profitable and prevent you from doing any "extra" or "free" work. It is developed in Agile Toolkit and can be customized to your own needs or workflow.
