30 days written notice before subscription term end. Either party can give notice of non-renewal at least 30 days before the end of a subscription term to stop auto-renewal. For Enterprise contracts, the deadline is typically 30-90 days before contract end. Monthly plans receive renewal notices 30 days before billing date; annual plans receive 60-90 days notice.
Commitment
1 year (annual plans)
Pro and Business+ have no published minimum seat count, but even 2-person teams pay for a minimum of 3 seats. Enterprise+ requires annual commitment, typically 1-3 year terms. Legacy Enterprise Select required a minimum of 9 users at $240/user/year on annual agreements only. Multi-year contracts (2-3 years) can save 15-25% compared to annual renewals.
Price escalation
No published escalation schedule; users report mid-contract surprise charges for add-ons
Since the Salesforce acquisition, Slack enforces a mandatory 9% year-over-year price increase at renewal unless specific conditions are met: demonstrating 15-20% ARR growth, committing to multi-year contracts, or adding new Salesforce products. Over four years, the 9% annual uplift adds approximately $38,313 to cumulative subscription cost for a mid-size deployment — a 38% total increase. Business+ pricing increased 20% in 2025 (from $12.50 to $15/user/month) to reflect bundled AI features. Enterprise Select and Enterprise Grid were consolidated into Enterprise+ in August 2024. Annual contracts often include language allowing 5-7% price increases at renewal.
