Trello – Trello is a collaboration tool that organizes your projects into boards. Trello adapts to your project, team, and workflow. You’ll see everything about your project just by glancing at the board, and it all updates in real-time. Trello really keeps me and my team on track to completing tasks on time.
Slack – this real time messaging allows us to collaborate in an instant and what is super sweet slack integrates with TeamworkPM, Infusionsoft, Dropbox and Twitter just to name a few. Slack keeps communications organized and allows you to choose what communications you want to be part of. Slack is free with unlimited users.
Google Hangouts – When we added Google Hangouts as our tool of choice for team meetings it was unanimous that this was by far the best way for us to connect and collaborate. The sound quality and connection is great. We really felt like we were all meeting in the same room.
