tl;dr - if your organization is $1B revenue and up, or smaller but in a highly regulated industry where you'll need to deal with Slack eDiscovery and/or DSARs or FOIA requests, Enterprise+ is probably for you. Midmarket organizations can often get away with Business+ in order to get Slack Compliance Exports. Startups and profitable SMBs often choose Pro due to low compliance requirements. Pre-revenue teams, communities, and side hustlers can start with the free plan while being aware of the free plan's limitations.

Do You Need The Enterprise Plan?

Strongly consider purchasing Enterprise if you are:

• A very large organization (2,000+ employees)
• In a highly regulated industries (finance, healthcare, government contractors)
• An organizations with multiple business units, brands, subsidiaries, or regions that each need their own workspace but under central governance

If this seems similar to the Business plan, consider that with Enterprise you'll get:

• Unlimited workspaces under one umbrella, often you'll need one per each subsidiary for example, but with centralized security + compliance policies
• Granular governance — e.g., Legal gets one workspace, Engineering another, and/or each subsidiary has its own environment; e.g. if one operates under a stricter compliance environment than another
• Org-wide security policies (retention, DLP, legal hold) that can be enforced across all workspaces
• Org-level audit logs and eDiscovery integrations
• Ability to support cross-workspace channels for collaboration, while maintaining segregation of sensitive units
• Examples:
  • A global bank with separate subsidiaries (retail, investment, insurance) that each need distinct workspaces, but must meet strict FINRA/SEC compliance
  • A university system with multiple campuses, each needing autonomy but under central IT governance
  • A Fortune 500 company with dozens of business units, each with its own Slack workspace, but requiring centralized legal hold and eDiscovery

In short:

• Need just one workspace, manageable IT, need uptime/SSO/compliance exports? → Get Business+
• Need many workspaces, multi-brand/regional structure, enterprise compliance/governance → Get Enterprise+ Grid
