Best productivity software for businesses
Kahu team·Updated 2 Oct 2026·7 min read
Productivity software for a small team usually covers four jobs: documents and email, team chat, notes and knowledge, and tasks. Well-known options include Google Workspace or Microsoft 365, Slack, Notion, and Trello or Asana. Most have free plans. Pick one tool per job, agree how the team uses it, and stop there.
Four jobs, one tool each
Productivity tools save time only when everyone uses the same one for the same thing. Two chat apps or three task lists cost more time than they save, because nobody knows where to look. Decide the job first, then the tool.
Documents and email
Google Workspace and Microsoft 365 both cover business email, calendars, shared files and video meetings. Google Workspace runs in the browser and offers a free trial. In Microsoft 365, Business Basic includes the web versions of the apps, while Business Standard and Business Premium add the desktop apps.
Team chat
Slack organises conversation into channels and direct messages, with connections to other tools. Its free plan keeps 90 days of message history and limits huddles to one-to-one. If you already use Microsoft 365, Teams is included in its business plans.
Notes, knowledge and tasks
Notion combines documents, a knowledge base and projects in one workspace, and has a free plan. Trello uses boards, lists and cards with built-in automation, and its free plan allows up to 10 collaborators per workspace. Asana manages projects across teams, with a free personal plan for up to two users.
| Tool | Good for | Watch out for |
|---|---|---|
| Google Workspace | Browser-based email, documents and meetings | AI features vary by plan |
| Microsoft 365 | Teams used to Word, Excel, Outlook and Teams | Desktop apps not in Business Basic |
| Slack | Fast team chat by topic | Free plan keeps only 90 days of history |
| Notion | Wikis, notes and simple projects in one place | Flexible enough to get messy without some rules |
| Trello | Simple visual task boards | Free plan limits collaborators per workspace |
| Asana | Projects with several people and deadlines | Free plan is for up to two users |

- Write down which tool is for what, in one sentence each.
- Customer conversations belong in your inbox or CRM, not in team chat.
- Archive old boards and channels every few months.
- Before adding a tool, check whether one you pay for already does it.
Frequently asked questions
Do small teams need Slack if they have email?
Not always. Chat helps when quick questions are clogging email. For a team of two or three, email and a shared task list may be enough.
Notion or Trello?
Trello is quicker for a simple task board. Notion suits teams who also want documents and a knowledge base in the same place.
Are free plans enough?
Often, for a small team. Upgrade when a limit, such as message history or number of users, starts to get in the way.
