We have been using Slack as our internal communication channel since 2015. When you manage people who do not work in the same office, or even in the same country then a tool like Slack is just brilliant.
Key features include:-
- The free version is adequate for smaller businesses (we have over 20 people on our account
- Private Channels
- Keep conversations out of your email inbox
- Works on mac,pc, all phone systems (yes, even Windows!)
- I love the integration with other software such as Room (for webinars), Zapier, Freshbooks, Mailchimp, reminders and 100's of other apps.
- A fab place to store documents and files and the search is so much better than our previous system
