# Claude vs ChatGPT for running a small business

Claude and ChatGPT both suit a small business; choose by the work your team can complete with its real information. Compare the team plans by billing commitment, seat requirements, usage limits and connected tools. Test customer replies, document work and connected actions before choosing, rather than relying on a general intelligence ranking.

## Which assistant should a small business choose?

Choose ChatGPT when its workspace and plugins fit the work your team already does; choose Claude when its Projects and connectors give your team a better working process. Judge both on correct completed work, including the time you spend checking and repairing it.

We make Mojobase, which connects to both. This comparison uses official OpenAI documentation and Anthropic's own pages, checked on 7 November 2026. The selection advice is our judgment; it is not a benchmark result or a claim that we tested every model.

For a consulting firm, the deciding job might be turning a brief into a proposal without inventing a delivery date. For a shop, it might be explaining a change in store sales using the right date range. A polished paragraph is useful only after those details are right.

## What are the concrete differences between their business plans?

Both entry business plans offer a paid company workspace, with different tools and usage allowances. The practical differences are the interface, the connected services your team needs and how people reuse context.

| Decision | ChatGPT | Claude |
| --- | --- | --- |
| Entry team subscription | Business: check current seat requirements and billing options | Team Standard: check current seat requirements and billing options |
| Work environment | ChatGPT and Codex access in the Business plan | Projects, collaboration, Claude Code and Cowork in Team |
| Custom remote tools | MCP servers packaged as plugins on the web | Remote MCP servers added as custom connectors |
| Workspace administration | Business lists admin controls, SAML SSO and MFA | Team lists central billing, administration and SSO |
| Model training default | No training on Business data by default | No training on Team content by default |

### ChatGPT: a good choice when the OpenAI workspace fits

ChatGPT is the better choice for a team that already gets reliable results in its workspace and wants its MCP tools available in that workflow. OpenAI documents shared MCP configuration between the ChatGPT desktop app, Codex CLI and IDE extension on the same host. That can matter when an owner and a technical teammate switch between those clients. It does not mean every connection works identically on every device. [Official MCP documentation](https://learn.chatgpt.com/docs/extend/mcp).

### Claude: a good choice when Projects and its connectors fit

Claude is the better choice when your team prefers keeping a recurring job's material in a Project and working through Claude's connector interface. Anthropic's Team documentation lists Projects and workplace connections including Google Drive, Gmail, Google Calendar, GitHub, Microsoft 365 and Slack. Check the permissions and available actions for the connection you actually need. [Official Team documentation](https://support.claude.com/en/articles/9266767-what-is-the-team-plan).

### Neither: a substitute for accessible business records

Neither assistant can reliably answer a question from records it cannot reach. Before paying for a second assistant, check whether the first one has the relevant policy, conversation and current customer details. Better context may improve the result more than changing the assistant's name.

## How much should you budget for five people?

Budget for the seats each person needs, then compare monthly billing with an annual commitment. Check minimum seats, taxes and additional usage before buying. A minimum seat purchase or higher-usage tier can change the quote; budget for the actual package each provider offers.

Claude also lists Premium seats for higher usage; check the current offer before budgeting. Give those to people whose actual workload warrants the cost; five Standard seats and five Premium seats are different purchases.

A subscription is not unlimited business automation. Record any extra credits, API use, connected software and staff review time in the budget. Compare that total with a working result, such as a checked proposal or a correctly prepared customer reply.

## How do you test both assistants fairly?

Give each assistant the same five anonymized work samples, the same instructions and access to equivalent source material. Score factual accuracy before style, and count the minutes a person needs to reach a usable result.

| Test job | Give the assistant | Check before awarding a pass |
| --- | --- | --- |
| Answer a customer | A question and the current return policy | Correct policy, no invented exception, a sendable draft |
| Prepare a meeting | An email thread and the agreed agenda | Correct people, unresolved questions and source links |
| Review a proposal | A brief and an existing offer | Missing assumptions identified; no invented promises |
| Explain store performance | Dated sales and ad-spend figures | Correct period, arithmetic and limits of the conclusion |
| Prepare follow-up work | Meeting notes with explicit commitments | Correct task owner, date and link to the original note |

Run the exercise with the people who will use the tool, not just the person buying it. Record the model and plan used, whether web search or connected tools were enabled, and any missing information. Repeat a failed job once with a clearer brief to distinguish an instruction problem from a persistent error.

## What should you check before connecting company data?

Check who can enable a connection, whose permissions it uses, what it can change and where information is retained. A no-training default answers one data-use question; it does not settle access, retention or the policies of a connected service.

OpenAI's [plugin controls](https://learn.chatgpt.com/docs/enterprise/apps-and-connectors) describe workspace permissions for connected tools. Anthropic's [custom-connector guide](https://support.claude.com/en/articles/11175166-getting-started-with-custom-connectors-using-remote-mcp) describes adding remote MCP services. Both sources were checked on 7 November 2026.

For a first connected workflow, retrieve a customer record and draft a response before enabling a tool that sends anything. Review the action's destination as well as its wording. A correct draft sent to the wrong customer is still a failed job.

## Where does Mojobase fit if you choose either assistant?

Mojobase gives either assistant one MCP connection to the business's Email, Calendar, Documents, Tasks, Customers, Numbers and Handbook, under the same permissions as the screens. The assistant reads the Handbook's business profile for your policies and tone, then searches the records needed for a particular job.

For example, ask it to prepare a customer call from the email thread, the next meeting and open tasks, or to draft an answer from a published Handbook policy. Numbers reads Shopify, Amazon and ad platforms; it does not provide bookkeeping, expenses or bank balances.

Every change appears in Activity with the acting person's and agent's identity, with Undo where the app supports it. Scheduled runs only draft and suggest; other supported changes follow Suggest or Auto settings by kind of change. An external message cannot be recalled by a general Undo promise.

Mojobase is useful when business context is the missing piece. Stay with the assistant alone when your job is occasional writing or analysis of a few supplied files. Use the [ChatGPT connection guide](https://mojobase.ai/agents/chatgpt) or [Claude connection guide](https://mojobase.ai/agents/claude) when you need the assistant to work across the business itself.

For inbox-specific setup, use the [ChatGPT-to-Gmail guide](https://mojobase.ai/blog/how-to-connect-chatgpt-to-gmail) or the [Claude-to-Gmail guide](https://mojobase.ai/blog/how-to-connect-claude-to-gmail).

## Questions people ask

### Is Claude or ChatGPT better for a small business?

Choose the assistant that produces more correct, usable work from your own records. Claude suits teams that prefer its Projects and connector workflow; ChatGPT suits teams that prefer its plugins and ChatGPT/Codex workflow. Neither preference establishes a universal winner on accuracy.

### How much do their business plans cost monthly?

Check the current ChatGPT Business and Claude Team offers for your required seats, billing commitment and usage. This guide does not quote their prices. Include taxes and additional usage in your comparison, and distinguish standard seats from higher-usage options.

### Do business plans train models on our data?

OpenAI says ChatGPT Business does not train on business data by default, and Anthropic makes the same default commitment for Claude Team content. Those commitments do not mean that no data is stored or processed; check retention and connected-service policies separately.

### Can either assistant work in Mojobase?

Yes. ChatGPT and Claude connect to Mojobase over MCP, acting with the person's own permissions. The connection reaches the business's apps, and changes appear in Activity with Undo where the app supports it. Each assistant still uses its own subscription.
