Quick Verdict
ChatGPT Business and ChatGPT Enterprise are the same product at two levels of governance. Business is self-serve: $20/user/month billed annually ($25 monthly), a two-user minimum, Premium seats for heavy users, SAML SSO and admin controls, and no training on your data by default. Enterprise is contract-priced and adds the things a security review asks for, SCIM provisioning, audit logs, data residency and retention controls, and role-based access, along with a 128K (GPT Instant) context window.
The choice is rarely about capability. Both tiers get GPT-6 and GPT-6 Pro and both give every seat ChatGPT and Codex. The question is whether your organization is required to prove how access is granted and revoked.
Pricing
- ChatGPT Business Standard seat: $20/user/month billed annually, or $25/user/month billed monthly. Minimum two users. The price is on the pricing page, so you can budget without talking to anyone.
- ChatGPT Business Premium seat: $100/user/month billed annually, or $125/user/month billed monthly. About 5x the usage of a Standard seat with no 5-hour usage limit, for the few people who do the heavy work.
- ChatGPT Enterprise: custom contract pricing through sales. No public seat rate, and terms vary by organization size, commitment and support level.
That asymmetry is the real difference for a small team. Business can be expensed on a card this afternoon. Enterprise involves a procurement cycle, which is worth starting only if a compliance requirement is driving it.
What Enterprise Adds
- SCIM provisioning. Business manages seats by hand; Enterprise syncs them from your identity provider. For an organization above roughly fifty people this stops being a convenience and starts being an audit finding.
- Audit logs and the Compliance API. Enterprise exposes usage and administrative events programmatically. Business does not.
- Data residency and retention controls. Enterprise lets you set where conversations live and how long they are kept. Business inherits OpenAI’s defaults, which already exclude training on business data.
- Role-based access control and domain verification. Enterprise separates administrators from members with granular roles.
- 128K context. Business runs a 54K window on GPT Instant. GPT Reasoning is 256K on both.
Which One To Pick
Pick Business if you are a team rather than an enterprise: no SCIM requirement, no auditor asking for access logs, and a headcount you can manage manually. It is the cheapest way to put governed ChatGPT and Codex in front of a whole team, and the seat price is low enough that it competes with buying individual plans.
Pick Enterprise if a compliance obligation names the features above, if you need the 128K GPT Instant window for long-document work, or if your identity team will not accept manual provisioning. Do not pick it for capacity alone: a Business Premium seat or an individual ChatGPT Pro plan gives a heavy user far more throughput without a contract.
