The Real Cost: Notification Fatigue
Beyond subscription fees, Slack's always-on ping culture costs teams in lost deep work. Research suggests constant interruptions reduce developer productivity by 20–40%. For a 25-person team, that's a hidden cost of $50,000/month in lost productivity (at $80k avg salary, conservative 30% impact estimate).

Enterprise Grid is typically quoted at $15–$25/user/month with volume discounts. At 25 users, expect $4,500–$7,500/yr. Enterprise Grid becomes cost-competitive with Business+ only above ~500 users due to unlimited workspaces, HIPAA compliance, and dedicated support.
