What Small Businesses Don’t Need
Avoid paying for enterprise features SMBs rarely use:
- Single sign-on (SSO) — until 50+ employees
- Compliance certifications (HIPAA, FedRAMP) — only if regulated industry
- Advanced admin controls — overkill for small teams
- Premium support tiers — community support often sufficient
Common SMB Chat Mistakes
- Email habits in chat — formal greetings and signatures slow everything down
- Too many channels — start with 5–10 channels, not 50
- No naming convention — chaos at scale
- Mixing internal and client comms — separate tools or clear channel boundaries
- Notification overload — train team on muting, threads, and DND
Migration Tips
Most teams migrate from email to chat. Tips:
- Don’t migrate all at once — start with 1–2 use cases
- Set chat etiquette norms early — response time expectations, threading
- Pin important channels to drive engagement
- Use one tool only for internal team communication
