The short answer
The headline seats are the same and the contracts are not. A Claude Team standard seat and a ChatGPT Business standard seat both cost $20 per user per month billed annually ($25 monthly), and both include usage inside published limits. Above that the two vendors diverge sharply. Claude Enterprise is $20 a seat with no usage included at all, every token billed at API rates, and a 20 seat minimum. ChatGPT Enterprise publishes no price, is quote only, and sits behind a hard 200 paid seat ceiling on ChatGPT Business that OpenAI says its support team cannot raise. Claude Team stops at 150 people. So for a business the real question is not which model writes better. It is which billing model you can forecast.

Almost every Claude versus ChatGPT comparison written for businesses is really a comparison of writing style. One is more careful, the other has more toys, both are good, pick whichever your team prefers. That is a fine article for an individual spending twenty dollars of their own money. It is close to useless for someone who has to put a number in a budget and defend it.
The commercial terms are where these two products actually differ, and they differ enormously. One vendor publishes every price and meters usage on top. The other publishes a price up to a ceiling and then stops publishing anything. One has a seat floor, the other has a seat cap. Neither of those facts appears in the comparisons currently ranking for this question, and both of them will change what you pay by more than any difference in output quality.
What Claude costs a business
Claude Team is $20 per standard seat per month billed annually, or $25 monthly, for teams of 2 to 150 people, with usage included inside published limits. Claude Enterprise is also $20 per seat, billed annually only, with a 20 seat minimum and no usage included whatsoever.
The sentence that matters is in Anthropic's Enterprise billing article, and it is unambiguous: the seat fee gives each person access to Claude across web, desktop, mobile, Claude Code and Cowork, but "doesn't include any usage. Every token your team consumes is billed separately at standard API rates." A Claude Enterprise seat is a license to be metered.
| Claude plan | Published seat price | Seat floor and ceiling | Usage |
|---|---|---|---|
| Team, standard seat | $20 per seat per month billed annually, $25 monthly | 2 to 150 people | Included inside published limits. Extra usage bundles available |
| Team, premium seat | $100 annually, $125 monthly | Same range, seat types mix freely | 5x standard seat usage, still included |
| Enterprise, self serve | $20 per seat, annual billing only | 20 seat minimum. No mid term seat removals | Nothing included. Credits bought up front. At zero, usage stops for everyone |
| Enterprise, sales assisted | $20 per seat, annual billing only | 20 seat minimum. Invoicing and net terms available | Nothing included. Metered and invoiced monthly in arrears |
The 20 seat minimum is the number nobody quotes, because it is not on the pricing page. It appears in the Team to Enterprise migration guide, in the step where you pick a seat count: "Add the number of seats needed for all your team members (Enterprise organizations have a 20 seat minimum)." A 12 person company that needs audit logs is buying 20 seats, so the floor is $4,800 a year before a single token is billed. The full breakdown, including the model by model usage arithmetic, is on our Claude Enterprise pricing page.
What ChatGPT costs a business
ChatGPT Business is $20 per Standard seat per month billed annually, or $25 monthly, and $100 per Premium seat annually or $125 monthly, with a two seat minimum. ChatGPT Enterprise has no published price at all. It is quote only, annual, and invoiced.
OpenAI is straightforward about the gap. Its plan FAQ says "Business plans are available starting at 2 users. Please contact sales to learn more about our Enterprise plan." Every specific ChatGPT Enterprise per seat figure in circulation is procurement data from a buyer or a reseller, not a number OpenAI has written down, and it should be labelled that way whenever it is used. The full breakdown of what OpenAI does and does not publish is on our ChatGPT Enterprise pricing page.
The number that decides more deployments than the price is the ceiling. Since August 24, 2026, OpenAI caps a ChatGPT Business subscription at 200 paid Standard and Premium seats in total, and adds a sentence you rarely see from a software vendor: "Our support team is unable to change your maximum seat limit." Seat 201 is not an upgrade button. It is a sales cycle, a security review and an annual invoice. We covered what that crossing costs in the ChatGPT Business 200 seat cap.
One more billing term worth reading before you size the order: "Unused ChatGPT seats are not refundable once you commit to a seat count on either a monthly or annual plan." You are billed on the seat count, not on who signed in.
Claude vs ChatGPT for business, on the terms that actually bind you
| Commercial term | Claude | ChatGPT |
|---|---|---|
| Entry seat price | $20 annually, $25 monthly (Team) | $20 annually, $25 monthly (Business) |
| Heavy user seat | $100 annually, $125 monthly (Team premium) | $100 annually, $125 monthly (Business Premium) |
| Minimum seats | 2 on Team, 20 on Enterprise | 2 on Business, not published on Enterprise |
| Maximum seats before sales | 150 on Team. Enterprise self serve has no published cap | 200 on Business, and support cannot raise it |
| Top plan price | Published: $20 a seat plus metered usage | Not published. Quote only |
| How usage is funded on the top plan | API rates. Credits up front (self serve) or invoiced in arrears (sales assisted) | A shared credit pool negotiated at contract level, trued up roughly quarterly |
| What happens when the money runs out | Self serve: usage stops for the whole organization until an Owner buys credits | Advanced features pause unless Workspace Owners enable overages |
| Monthly billing on the top plan | No. Enterprise is annual only | No. Enterprise is annual only |
| Trial | Sales assisted Enterprise only. Not on self serve or Team | Not published for Business or Enterprise |
Read down that table and the pattern is clear. At the entry tier these two products are commercially identical, to the dollar, on both seat types. Everything that separates them happens at the point where a business stops being small.
The three differences that decide it
First: whose usage risk is it? ChatGPT Enterprise buys a credit pool at the contract level, so the negotiation happens once a year and your exposure between true-ups is bounded by what you bought. Claude Enterprise meters every token, so your exposure is bounded only by the spend limits you remember to set. Anthropic is candid about that: owners can set a limit to unlimited, but "consumption will still be billed. You cannot disable billing for usage." If your finance team hates variable bills, that sentence is your answer.
Second: which wall do you hit first? Claude Team ends at 150 people. ChatGPT Business ends at 200. Both walls arrive well before most companies think of themselves as enterprise buyers, and the consequences are opposite. Crossing Claude's wall drops you onto a plan with a published price and an unpublished bill. Crossing OpenAI's wall drops you onto a plan with no published price at all. Pick the one whose unknown you are more comfortable negotiating.
Third: what does a security review need? On Claude, audit logs, SCIM, role based access, the Compliance API, custom data retention controls and a HIPAA ready offering are all Enterprise only, which means a healthcare or regulated buyer cannot use Team at any price and lands on the 20 seat minimum by default. On ChatGPT, RBAC, SSO and SCIM sit on Enterprise and Edu. In both cases the compliance checklist, not the headcount, is what moves you up a tier, and it is usually a compliance officer rather than a budget holder who triggers the upgrade.
Where both of them stop being the answer
Both vendors sell an assistant per person, and both handle permissions properly: an administrator enables a connector for the organization, then each individual authorizes their own account, and the assistant inherits only what that person can already open. Credit where it is due. Several better known products get this wrong.
The commercial consequence is the part worth planning around. Because each connection is authorized per person, coverage is per person and opt in. OpenAI states it twice in its own documentation: "installing the plugin does not connect your app accounts" and "Plugin installation does not connect individual app accounts or grant access to source data." Anthropic's connector model works the same way. In a 400 person company with five connected systems, full coverage means 2,000 individual OAuth grants that no administrator can complete on anyone's behalf. What you get in practice is an assistant that knows a lot about whatever each person happened to connect, and nothing about the company as a whole.
That matters because it is a different job from the one most businesses describe when they say people cannot find anything. "What did we tell this customer about renewal terms in March" is not a reasoning problem. It is a retrieval problem, and it needs an index of the company connected once by an administrator, not 2,000 personal authorizations. It also prices differently: retrieval cost per query barely moves whether the question is easy or hard, which is why search can be sold flat while an assistant that thinks harder has to cost more.
There is a third category worth naming so you do not buy the wrong one of the three. If the job is neither "answer my question" nor "find our document" but "go away and complete this multi step task", that is an agent that runs the task end to end, and it is bought and budgeted differently again.
InSearch does the retrieval job: one permission aware index across Google Drive, Slack, Notion, Confluence, Gmail, Jira and Salesforce, one question in plain English, one written answer with inline citations back to the source document, priced per seat with no token meter. Plenty of companies run an assistant and an index side by side, and that is a perfectly sensible answer. The mistake is buying one and expecting the other.
So which should a business buy?
Under 150 people with no compliance requirement: the two entry plans cost the same to the dollar, so choose on which one your team prefers using and keep the monthly option until you are sure. Neither vendor gives you a discount for guessing early.
Between 150 and 200 people: Claude Team has already run out and ChatGPT Business has not. That is a genuine, temporary advantage for OpenAI in a narrow band, and it lasts exactly until you hit 200.
Above 200 people, or with a compliance checklist: you are negotiating either way. Ask Anthropic for a spend limit structure and a modelled monthly usage figure at your headcount rather than accepting the $20 seat as the number. Ask OpenAI what happens at the true-up and what the pool costs to top up mid term. In both cases the seat price is the least interesting line in the contract.
If the actual complaint is that nobody can find anything: price a search index separately before you upsize either assistant, because a per person assistant that has to be connected per person will not solve it at any seat price. Our comparison of sixteen products is on the enterprise search tools page, and the seat thresholds every vendor in the category hides are in enterprise search software for teams over 100 users.
Frequently asked questions
Is Claude cheaper than ChatGPT for business?
Not at the entry tier: Claude Team and ChatGPT Business are both $20 per standard seat per month billed annually and $100 for a heavy usage seat. Above that Claude publishes a $20 Enterprise seat and meters usage at API rates on top, while OpenAI publishes nothing for Enterprise. Claude is the only one of the two whose top plan carries a public number, but that number is not the bill.
Which is better for business, Claude or ChatGPT?
On commercial terms they are close to identical up to 150 people and diverge after. Claude gives you a published top tier price with a variable usage bill and a 20 seat minimum. ChatGPT gives you a fixed, predictable seat up to 200 people and then a quote. Choose on which uncertainty you can manage, because at the entry tier there is no price advantage either way.
Does Claude Enterprise include usage?
No. Anthropic states that the Enterprise seat fee does not include any usage and that every token is billed separately at standard API rates. Self serve organizations buy credits up front and usage stops for everyone when the balance reaches zero. Sales assisted organizations are metered and invoiced monthly in arrears instead.
How many seats can ChatGPT Business have?
Two hundred paid Standard and Premium seats in total, since August 24, 2026, and OpenAI states that its support team cannot change the limit. Workspaces created before that date keep their previous limit. Above the cap the only route is a ChatGPT Enterprise contract, which carries no published price.
Do I need Claude Enterprise or is Team enough?
Team is enough unless you need audit logs, SCIM, role based access, the Compliance API, custom data retention, a HIPAA ready offering or a 500k context window, or you have more than 150 people. Those are the only rows that differ on Anthropic's own comparison table. If none of them are on your list, Team costs the same per seat and includes usage.
