You fix the same problem for the third time this year. Here's why most SME "lessons learned" evaporate — and the 70-20-10 rule that makes them stick instead.

There is no single winner between ChatGPT, Claude and Copilot for a New Zealand business. The right one is the tool that does your three most common jobs best, inside the systems you already use, with data controls you are comfortable with. Run the same three real tasks through each tool for one afternoon, score them on five criteria, and pay for the one that wins.

Kevin D'Ambros-Smith is an Auckland-based business coach and advisor who has coached 200+ businesses one-on-one across 30+ industries. This guide is for owners who know they should be using AI properly but are not sure which tool to pay for. It is general business guidance, not legal, privacy or IT security advice. Simple-Growth has no commercial relationship with OpenAI, Anthropic or Microsoft.

Why is choosing an AI tool so hard for NZ owners?

Because every review online is written for someone else. Prospa's SME Sentiment Tracker, a survey of 501 New Zealand SME decision-makers run by Clarity Insight, found 59% now use AI in some form, up from 50% six months earlier. Among the owners not using it, 32% said they did not know which tools suited their needs, and 34% were unsure of the return.

Both of those barriers have the same fix. Stop comparing feature lists and test the tools on your own work. A plumber, a physio clinic and an export food brand will each get a different answer, and that is the point.

Which is better for business: ChatGPT, Claude or Copilot?

Each one is built around a different starting point, and that matters more than any benchmark.

  • ChatGPT, from OpenAI, is a general-purpose assistant you use in a browser or app. It suits owners who want one tool for writing, research, ideas and analysis across everything they do.
  • Claude, from Anthropic, is also a general-purpose assistant used in a browser or app. Owners often trial it for long documents, careful writing and working through a problem step by step.
  • Microsoft 365 Copilot works inside Word, Excel, Outlook, PowerPoint and Teams. It suits businesses that already run on Microsoft 365 and want help inside the files and emails they already have.

All three change quickly. A tool that lost your test in March may win it in November, so treat your choice as a yearly decision, not a marriage.

What does each one cost?

Prices below are in US dollars, exclude GST and were read from each vendor's own pricing page on 13 November 2026. Your local price and plan names may differ, so check before you buy.

  • ChatGPT: a free plan; Plus at USD 20 a month; a business plan from USD 25 per user a month billed annually.
  • Claude: a free plan; Pro at USD 20 a month, or USD 17 a month billed annually; Team from USD 20 per seat a month billed annually, for 2 to 150 seats.
  • Microsoft 365 Copilot Business: an add-on for existing Microsoft 365 business customers at USD 18 per user a month on an annual commitment, a first-year offer that runs to 31 December 2026 (USD 21 otherwise).

For a five-person team, the gap between these plans is small next to the value of one hour a week saved per person. Cost is rarely the deciding factor. Fit is.

How do you run a fair test in one afternoon?

Use the free plans or trials, and give every tool exactly the same three jobs taken from your real week. Remove customer names and personal details first.

  • The writing job. Paste in a real customer complaint or tricky enquiry and ask for a reply in your voice. Judge whether you would send it with light edits.
  • The reading job. Give it a long document, such as a supplier agreement, a tender or last quarter's board report, and ask for the five things you need to act on. Check every point against the original.
  • The numbers job. Upload a spreadsheet export of sales by customer and ask which customers make up most of your revenue and which have stopped buying. Check the answer against your own figures.

Then score each tool from 1 to 5 on these five criteria:

  • Accuracy: did it get the facts and the numbers right?
  • Voice: does the writing sound like your business, not a robot?
  • Time saved: how long would the job have taken you by hand?
  • Fit: does it work where your files, email and team already are?
  • Control: can you manage how your data is used, and can you manage users when staff come and go?

The highest total wins. If two tools are close, choose the one your team will actually open every day.

Is Copilot better than ChatGPT if you use Microsoft 365?

Not automatically. Copilot's advantage is location: it works inside the documents, spreadsheets and inboxes your business already uses, which removes the copy-and-paste step. If your business lives in Outlook, Excel and Teams, include Copilot in your test. If most of your work happens in Google Workspace, an industry system or a browser, a standalone assistant may fit better. The test settles it, not the logo.

Is it safe to put business information into an AI tool?

It can be, with sensible rules. The Privacy Act 2020 applies to personal information you put into AI tools, and New Zealand's Office of the Privacy Commissioner publishes guidance for organisations using them. Before you pay, check the plan's data settings, including whether your content can be used to train the vendor's models, and choose a business plan if staff will handle customer information.

Write a one-page AI rule for your team: what can go in, what never goes in, and who checks anything before it reaches a customer.

What should you do after the test?

Picking the tool is the easy part. The value comes from putting it to work on the constraint that is holding the business back. Here is a simple 90-day plan:

  • Days 1 to 30: run the test, choose one tool, write your one-page AI rule and train the team on the three jobs.
  • Days 31 to 60: point it at your biggest constraint. Quote follow-up, lapsed customers, proposals or month-end reporting.
  • Days 61 to 90: measure hours saved and results, then connect the tool to more of your systems or retire it.

One owner who did this connected her business systems to AI and put it to work on prospecting and lapsed customers:

"Kevin got me to connect our ERP, email, website and Google Analytics to AI, and it has changed how we find and keep customers. AI now writes tailored prospecting emails every day and reaches out to lapsed customers with the products they bought before, and we're already getting positive replies. Our blogs, newsletters and SEO are all stronger too. Kevin doesn't just talk about AI, he helps you put it to work in your business."

Frequently asked questions

Should a small business pay for more than one AI tool?

Usually not at the start. One paid tool that the whole team uses well beats three that nobody opens. Run the afternoon test, pick the winner, and review the choice once a year, because all three tools are changing quickly and a different one may suit you later.

Is the free version of ChatGPT or Claude good enough?

Free plans are fine for running the test and for occasional use. Once staff use AI every day or handle customer information, a paid business plan is worth it for higher limits, user management and stronger data controls. Check each plan's data settings before you decide.

Do I need Microsoft 365 to use Copilot?

For Microsoft 365 Copilot Business, yes. Microsoft sells it as an add-on for existing Microsoft 365 business customers, and also in bundles that include a Microsoft 365 business plan. If you run on Google Workspace, include a standalone assistant in your test instead.

How long before AI saves me time?

Most owners notice time saved on writing and reading jobs within the first week of daily use. Bigger gains come once the tool is connected to your systems and pointed at your main constraint, which is why the 90-day plan matters more than the tool you choose.

Your next step

If you have tried AI and it has not given you your time back, the tool is rarely the problem. The missing piece is usually a clear job for it to do. In a 30-minute conversation we can find the constraint worth pointing AI at first. There is no obligation.
