Project Category in Odoo helps you keep projects organized by grouping them into clear categories. You can create categories like Internal, Client Work, Support, or Development and assign them to each project. This makes it easy to sort, filter, and find the right projects without scrolling through a long list. Categories also give a quick overview on the project dashboard, so your team can understand what type of work is active at a glance. With better grouping, managers can track related projects faster and plan resources more smoothly.
