ChatGPT vs Microsoft Copilot for Small Business: Which Should You Use?

ChatGPT vs Microsoft Copilot for small business which should you use?

If you've been trying to work out whether your business needs ChatGPT, Microsoft Copilot, or both, you're not alone. They look similar on the surface both are AI assistants that generate text, answer questions, and help you work faster. But they're built differently, priced differently, and suited to different use cases. This comparison cuts through the noise so you can make the right call for your business.

What is the difference between ChatGPT and Microsoft Copilot?

ChatGPT

ChatGPT is a standalone AI assistant made by OpenAI. You access it through a browser or app, type a prompt, and get a response. It doesn't connect to your business files, emails, or calendar unless you specifically give it access.

Microsoft Copilot

Microsoft Copilot is AI built directly into Microsoft 365 Word, Excel, Outlook, Teams, and PowerPoint. It can read your documents, summarise your emails, generate meeting notes from Teams calls, and draft content using the context of your actual business data. It requires a Microsoft 365 subscription and an additional Copilot licence.

ChatGPT vs Microsoft Copilot side by side comparison

The table below compares the two tools across the dimensions that matter most for Australian small businesses.

Which should you choose?

Choose Copilot if:

• Your team already uses Microsoft 365 (Outlook, Word, Teams, Excel)
• You want AI that works with your actual business documents and emails
• Data privacy and Australian data residency matter to your organisation
• You want AI integrated into existing workflows rather than a separate tool
• You are implementing AI across a team and need admin controls and governance

Choose ChatGPT if:

• You don't use Microsoft 365, or use Google Workspace instead
• You need maximum flexibility for content creation, brainstorming, and research
• You want to experiment with AI before committing to a platform
• You need to work across different tools and don't require file integration
• You are a sole trader or individual user who wants a fast, flexible assistant

Use both if:

• You want Copilot for document and email work inside Microsoft 365, and ChatGPT for external content creation and research
• You have staff with different working styles and use cases
• You are willing to manage two AI policies and two sets of usage rules

A note on cost

Both tools cost roughly the same per user per month ChatGPT Pro at around $30/month and Copilot for Microsoft 365 at around $36/month. The difference is that Copilot requires an existing Microsoft 365 subscription (typically $15–$22/user/month for Business Standard or Premium). If your team isn't already on Microsoft 365, the total cost of Copilot is higher. If you are already paying for Microsoft 365, adding Copilot is a relatively small incremental cost. Both tools are available to Australian small businesses across Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, Hobart, and Darwin.

What about data privacy?

This is the question most Australian small businesses should be asking first. ChatGPT's default settings send your prompts to OpenAI's servers in the United States. If you are inputting client information, financial data, or anything covered by the Australian Privacy Act, you need to either use ChatGPT's enterprise settings (which provide stronger data controls) or avoid inputting sensitive information altogether.

Microsoft Copilot operates within your existing Microsoft 365 environment. Your data stays inside your Microsoft tenancy, under the same security and compliance settings you already have in place. For most Australian small businesses handling client data, this is a meaningful advantage.

Frequently asked questions

Is my business data safe in ChatGPT?

By default, ChatGPT (free and Pro) uses your conversations to improve OpenAI's models, and data is stored on US servers. You can opt out of training data use in settings. ChatGPT Enterprise offers stronger data protections including no training on your data and enterprise-grade security. For businesses handling sensitive client information, enterprise settings or careful input hygiene are recommended.

Is Microsoft Copilot worth the extra cost for a small business?

For businesses already on Microsoft 365, Copilot is worth evaluating seriously the integration with Outlook, Teams, and Word alone can save meaningful time on email and meeting administration. Whether it justifies the cost depends on how heavily your team uses Microsoft 365 and what specific tasks you want to automate. A one-month trial with a small group is usually the best way to assess value before rolling out broadly.

Can I use ChatGPT and Copilot at the same time?

Yes many businesses use both. A common pattern is Copilot for internal document work, meeting summaries, and email drafting, and ChatGPT for external content creation, research, and brainstorming. The main overhead is maintaining usage rules for both tools, which is manageable with a basic AI policy.

Which is better for a tradie vs a professional services firm?

For a tradie, ChatGPT is usually the better starting point it's simpler to set up, doesn't require Microsoft 365, and works well for quote drafting, client communication templates, and job note summaries. For a professional services firm already on Microsoft 365, Copilot offers more value because the integration with Outlook and Word directly addresses the highest-volume tasks.
