4. Trello
Up next in our list of free business productivity tools for small businesses is Trello, that is a fun and creative way of organizing and managing project and tasks. Color-coded and laid out in cards, this app lets you see your project pipeline, product updates, meeting deadlines, and more. Collaboration can be done directly with commenting and attachment features. Trello can also be integrated with other platforms and can be used on the web and on mobile devices. Its creative layout can inspire your team to work more productively, too!
