ChatGPT Business vs Plus vs Enterprise: which plan your team needs, with Australian prices

ChatGPT plans in Australian dollars

These are the prices OpenAI showed an Australian account in October 2026. Business prices include GST. Go, Plus and Pro are shown in Australian dollars too, but we couldn't confirm from OpenAI's own pages whether GST is added at checkout, so check your first invoice.

A team of ten on yearly billing pays A$280 a month for Business, or A$3,360 a year. On monthly billing it's A$350 a month.

Plus: fine for one person

Plus is a good personal plan. It includes ChatGPT Work for multi-step tasks across your apps and files, Codex, projects, and connections to apps like Gmail and Google Calendar. The limits show up when a team relies on it:

• Each person controls training. On personal plans, chats can be used to improve OpenAI's models unless the person turns off "Improve the model for everyone" under Settings, Data controls. You can't see or set that for them.
• No shared admin or billing. Everyone pays on their own card, and when someone leaves, their chats and projects leave with them.
• No new custom GPTs. Personal accounts, including Plus and Pro, can no longer create new GPTs. Existing ones still work until custom GPTs are retired.

Business: the right plan for most teams

Business gives you one shared workspace that belongs to the company.

• Admin and sign-in. Central billing, SAML single sign-on, multi-factor authentication, usage analytics and spend controls.
• No training by default. OpenAI says it doesn't use inputs or outputs from Business workspaces to improve its models.
• Two seat types. Standard seats suit most people. Premium seats give 5x the usage of standard and no five-hour limit. You can mix them, and buy workspace credits if someone needs more than their seat includes.
• Work tools. Both seat types include ChatGPT Work for multi-step tasks and Codex for coding. Workspace agents let people build shared assistants for repeat jobs, connect them to apps, and run them on a schedule or in Slack.
• Connections. Google Workspace, Microsoft 365, Slack, GitHub and more. Your Microsoft or Google administrator may need to approve access.

Two things Business doesn't fully cover. API usage is billed separately. Australian data storage is an Enterprise option for now. OpenAI is rolling out a choice of storage region when you buy Business, but it isn't available to everyone yet, OpenAI hasn't listed the regions, and a copy of prompts and responses is still kept in the US for a limited time.

Moving people off Plus. Each person can merge their personal workspace into the Business workspace. Their conversations, and the custom GPTs and projects they created themselves, come across. There's no undo, and some older conversations may not transfer, so ask people to save anything important first. We'd also check what they're bringing over, because a year of personal chats isn't always something the business needs.

Setting up Business properly

Buying the seats is quick. These are the steps we'd add before inviting the whole team:

• Turn on single sign-on if you use Microsoft 365 or Google Workspace, so people log in with their work accounts and lose access when they leave.
• Decide who gets premium seats. Start everyone on standard, watch who hits the limits in the first month, then move those people up.
• Set spend controls before anyone buys extra credits.
• Connect one app at a time, check what ChatGPT can see, then add the next.
• Bring Plus users across deliberately, after they've saved what matters.
• Write down what's safe to put in, and who checks work before it goes to a client. Our AI use policy template gives you a one-page version to edit.

Then train each team on its own emails and documents, with a champion or two who can answer questions once the training's done.

When Business isn't enough: signs you need Enterprise

Enterprise has no public price. It's worth a conversation with OpenAI's sales team if any of these apply:

• Your clients or regulator need Australian data storage. New Enterprise and Edu workspaces can keep their data in Australia, at no extra cost. Business is starting to offer a storage-region choice, but it keeps a US copy for safety checks.
• You need automatic user management. SCIM provisioning from your identity system and role-based access controls are Enterprise features.
• You need invoices and purchase orders. OpenAI says invoice billing, purchase orders and bank transfer need a contracted plan rather than self-serve Business.
• You need audit and compliance tooling. Enterprise includes Compliance API visibility over conversations and agent activity, plus 24/7 support with service levels.

For most businesses under 200 people, Business does the job. In our experience, the conversation about Enterprise usually starts with a client's data requirements.

Which plan your team should be on

• Only you use it: Plus.
• Two or more people use it for client or customer work: Business, standard seats.
• A few people use it all day: premium seats for them only. One person on Pro costs more than a premium Business seat on yearly billing, and Pro is a personal account, so there's no business admin and training is each person's choice.
• You need Australian data storage, SCIM or invoice billing: talk to OpenAI about Enterprise.

Custom GPTs are being retired

OpenAI plans to retire custom GPTs on 11 December 2026 and replace them with plugins. Enterprise workspaces with an approved deferral get until 11 February 2027, and on Enterprise, creating new GPTs is planned to stop on 26 October 2026. A built-in migration turns a GPT's instructions into a skill and copies its knowledge files across, but custom actions don't transfer and sharing settings don't carry over.

If your team relies on GPTs, list them now, note who built each one, and test the replacement before December. Our guide to Claude Projects, custom GPTs and Copilot agents covers what to build instead.
