First, split your team by AI need before choosing a tier, because the May 2025 repricing made AI the whole decision: Business at $20/member/month annually is exactly double Plus at $10, and the only self-serve difference most teams feel is full Notion AI (agents, meeting transcription, Enterprise Search). A 10-person team where only 4 people would use AI still pays for all 10 at Business rates — Notion does not sell AI per-member any more — so if fewer than half your team needs AI, staying on Plus saves $1,200/year per 10 members. Second, always take annual billing once you are committed: monthly is a straight 20% premium ($12 vs $10 on Plus, $24 vs $20 on Business), which is $480/year of pure waste on a 10-member Business team. Use the refund windows as your safety net — 30 days on annual plans (14 days in the EU/UK) is enough for a real trial. Third, claim the free routes: the Plus plan with a 1-member limit is free for students and educators with a school email, and the Free plan is genuinely unlimited for individual use, so solo founders should not pay until a second member joins. Fourth, if you are eyeing Enterprise, negotiate — it is custom-priced, and the unique lever is AI data handling: zero data retention with LLM providers is Enterprise-only, so security review requirements are your justification for asking for Business-level per-seat pricing on an Enterprise contract. Fifth, watch metered AI: Custom Agents bill at $10 per 1,000 monthly Notion credits and Workers begin consuming credits from 11 August, so cap agent experiments before they quietly become a second subscription. Finally, prune guests and members quarterly — mid-cycle additions are prorated automatically, and stale members are the most common silent overspend.
