ChatGPT Enterprise pricing
What OpenAI publishes, what it doesn’t, what third parties report, and what the published ChatGPT Business plan costs, checked against OpenAI’s own pages in September 2026. Then the option most buyers never price.
How much does ChatGPT Enterprise cost?
OpenAI does not publish ChatGPT Enterprise pricing. As of September 2026 the plan is bought at organisation level through OpenAI’s sales team, on annual contracts, with the price set in the agreement. Third-party reports put it at roughly $45 to $75 per user a month with seat minimums around 150, and those are reports, not OpenAI’s figures. Since 2026 eligible Enterprise agreements also meter usage beyond included limits in credits or per token, so the seat fee is not the whole bill. What OpenAI does publish is ChatGPT Business, the plan for 2 to 200 people: a standard seat at £15 a month billed annually or £18 monthly, and a premium seat with five times the usage at £75 or £90, as shown to a UK buyer. If you need SCIM, a Compliance API, key management or a specific data residency region, those sit in Enterprise and the only way to learn the price is to ask.

What OpenAI publishes about ChatGPT Enterprise
From chatgpt.com/pricing and OpenAI’s Enterprise help article, September 2026. Where OpenAI does not publish a figure, the table says so and labels any third-party number as a report.
| Fact | ChatGPT Enterprise |
|---|---|
| Published price | None. Contact sales. |
| Reported price | Roughly $45 to $75 per user a month, according to third-party reports. Not an OpenAI figure. |
| Minimum seats | Not published. Third-party reports say around 150. |
| Contract | Annual only. |
| Usage | Seats include baseline access. On credit-based and token-based agreements, usage beyond included limits is billed in workspace credits or per token. |
| Included controls | SAML SSO, SCIM, role-based access, Enterprise Key Management, Compliance API, IP allowlisting, analytics dashboard, data residency in the US, EU, UK, Japan, Canada, Korea, Singapore, India, Australia and the UAE. |
| Models | OpenAI only. The console does not govern Anthropic, Google or open models. |
An unpublished price is a negotiating position. If you get a quote, the number to compare it against is the whole bill, seats plus metered usage, not the per-seat figure alone.
The plan OpenAI does price: ChatGPT Business
Published on chatgpt.com/pricing, shown here as it appears to a UK buyer in September 2026. Other regions see local currency.
| Fact | ChatGPT Business |
|---|---|
| Standard seat | £15 a month billed annually, £18 billed monthly. |
| Premium seat | £75 a month billed annually, £90 billed monthly. Five times the usage of a standard seat. |
| Team size | 2 to 200 employees. Seat types can be mixed. |
| Included | SAML SSO and MFA, central billing and admin, usage analytics and spend controls, connectors to Google Workspace, Slack, GitHub and Microsoft 365, no training on your business data by default. |
| Not included | SCIM, Compliance API, Enterprise Key Management, IP allowlisting and the wider data residency list are Enterprise features. |
Business is the same shape as Claude Team: a flat seat price with a hard cap on team size, and the compliance controls held back for the plan without a price tag.
When ChatGPT Enterprise is worth asking for a quote
The cases where buying direct from OpenAI beats routing through us.
The ChatGPT Enterprise alternative- You need a specific residency region. OpenAI’s Enterprise residency list is the broadest of the two big vendors. If Japan, Korea, Singapore, India or the UAE is a hard requirement, that is a reason to talk to their sales team.
- You are large enough to negotiate. An unpublished price rewards companies with hundreds of seats and a procurement team. If standardising on OpenAI for a year is a deliberate strategy, buy direct and negotiate hard.
- Otherwise, price the third option. You want ChatGPT for everyone, EU hosted, with an audit trail and spend caps, without a seat minimum in the hundreds or an annual contract. That is what Harriet is for.
A published price for OpenAI’s models
We build Harriet, so read this as what it is. ChatGPT Enterprise is a reasonable buy for the companies above. For everyone else, the same OpenAI models come with a price you can see and a bill you can cap.

Pricing is quoted per organisation for the people actually provisioned.
Usage you can cap

See how implementation worksWhat that looks like on one bill. The same 180-seat scenario on both sides, so the only differences are the ones Harriet causes. OpenAI publishes no Enterprise seat fee, so the scenario uses $45, the low end of the reported band.
ChatGPT Enterprise
- Access fee, 180 seats $97,200
- Model usage, billed by the vendor $60,480
One scenario for both sides: 180 seats over 12 months, 70% active, $40 of frontier-model usage per active user per month, access fee $45 per seat per month, the low end of third-party reports, since OpenAI publishes none. Not a quote.
Harriet
- Flat platform fee Quoted. Does not move with seats.
- Model usage on your provider account, routed $29,635
Same usage scenario, with 60% of tasks routed to models at 15% of the price. The fee is stated in the comparison we send.
Questions buyers askabout the price
How much does ChatGPT Enterprise cost?
OpenAI does not publish a price. ChatGPT Enterprise is sold through OpenAI’s sales team on annual contracts and the price is set per agreement. Third-party reports put it at around $45 to $75 per user a month, with seat minimums around 150. Treat those as reports, not as OpenAI’s figures, as of September 2026.
Is there a minimum number of seats for ChatGPT Enterprise?
OpenAI does not publish one. Reports put it around 150. ChatGPT Business, the published plan, runs from 2 to 200 employees, so a team above 200 that wants to stay with OpenAI has to go through sales.
What does ChatGPT Business cost?
Shown to a UK buyer in September 2026: £15 a month per standard seat billed annually or £18 monthly, and £75 or £90 for a premium seat with five times the usage. It covers 2 to 200 people with SAML SSO, central admin and no training on your data by default. Prices in other regions are shown in local currency on OpenAI’s pricing page.
How does ChatGPT Enterprise pricing compare to Claude Enterprise?
Anthropic publishes its Enterprise seat fee, $20 a seat a month billed annually plus usage at API rates, with a 20-seat self-serve minimum. OpenAI publishes nothing for Enterprise and reports put it two to three times higher per seat, with a much larger minimum. Per-seat price is only half the bill on either platform, because usage depends on which models people use every day.
Is ChatGPT Enterprise billed per seat or per usage?
Both, depending on the agreement. Standard seats include baseline access. Since 2026, eligible Enterprise agreements meter usage beyond included limits in workspace credits or per token, and Codex-only seats are usage-based with no fixed monthly fee. Ask for the rate card before you sign, because the usage line is the part that moves.
Do we have to buy ChatGPT Enterprise to get EU data residency?
On OpenAI’s own plans, the wider data residency list, including the EU and UK, is an Enterprise feature. The alternative is to run OpenAI’s models EU-hosted through Harriet, alongside Anthropic’s, with no seat minimum and no annual contract, and choose per team where processing happens.
What is the alternative to ChatGPT Enterprise?
Harriet. Your people get ChatGPT and Claude, plus Gemini and open models, EU or US hosted, through one desktop assistant IT provisions to every device. Admins set which models each team can use, cap spend per team and per user, and audit every action down to the tool call. Pricing is quoted per organisation for the people actually provisioned, with no seat minimum, no annual commitment, and hands-on help building the first skills.
