Gemini vs Copilot (2026): Which Is Better for a Small Business, What Each Costs, and Why the Answer Is Usually the Suite You Already Pay For

Gemini vs Copilot: the short answer for a business

As of September 2026: use the assistant that lives in the office suite you already pay for. Gemini is included in Google Workspace Business plans from $7 a user a month. Microsoft 365 Copilot, the version that reads your files, mail, and meetings, is a $21 to $30 add-on per seat on top of Microsoft 365, while Copilot Chat and the consumer Copilot are free. Most "Gemini vs Copilot" pages compare the two as if you were choosing an assistant. You are not. You already chose a suite, years ago, when you set up email, and the assistant came bundled with that decision. The useful question is narrower: is the assistant inside your suite good enough, what does the paid tier actually add, and when is a third option (a $20 Claude seat) the better spend for specific people. That is this page.

What each one costs in 2026

Gemini, from workspace.google.com/pricing (read September 11, 2026): Business Starter is $7 per user a month on annual billing and lists "Gemini AI assistant in Gmail"; Business Standard is $14 and Business Plus is $22, both listing Gemini in Gmail, Docs, Meet, and more, plus Gemini Notebook and expanded access to models and features. Google prints an introductory discount for new customers beside those list prices (the first 20 users, for 12 months). There is no separate Gemini license for a Workspace business; the tier is the license. On the consumer side, the figures on my Google AI Pro review, since Google injects them in the browser: Google AI Plus $4.99, Google AI Pro $19.99, Google AI Ultra $99.99 to $199.99, and a free Gemini app.

Copilot is five products wearing one name, and I mapped the whole ladder on is Copilot free. The two that matter here: Copilot Chat, the web-grounded chat, is included with a Microsoft 365 business subscription at no extra license, and Microsoft 365 Copilot, the add-on that works inside Word, Excel, Outlook, and Teams with your tenant's data behind it, is $30 per user per month on enterprise plans and, as reported, $21 per user on the Business plans, with an $18 first-year promotional rate on annual plans bought by December 31, 2026. The Business figures are confirmed on Microsoft's Copilot Business and pricing pages (read September 12, 2026): $21 list, $25.20 paid monthly, and $18 for the first year on an annual plan bought between July 1 and December 31, 2026, for existing Microsoft 365 Business customers. The consumer Copilot in Windows, Edge, and the app is free; Copilot Pro, the old $20 consumer upgrade, closed to new customers on October 1, 2025 and was folded into Microsoft 365 Premium at $19.99, as reported.

The price that decides it: included versus add-on

Here is the arithmetic for a ten-person owner-led company. On Google Workspace Business Standard, the suite is $140 a month and Gemini costs $0 more; it is already in every inbox and document. On Microsoft 365, the suite is whatever your Business plan costs, plus $210 a month (at $21, or $180 in the first year on the promotional annual rate) to $300 a month (at $30) to put Microsoft 365 Copilot on all ten seats, or $0 if Copilot Chat is enough. That asymmetry is the whole comparison. Google priced the assistant into the suite; Microsoft priced it as a second product. Neither is wrong, but it means a Workspace company should simply turn Gemini on, and a Microsoft 365 company has a real purchasing decision to make, seat by seat.

The decision Microsoft is asking you to make: which people need the add-on that reads the tenant (summarize this thread, draft the deck from the doc, recap the meeting, ask Excel what changed), and which people are fine with Copilot Chat plus a browser. In most ten-person companies I have looked at, that is two or three seats, not ten.

Where Gemini is better

• It is already on. For a Workspace company there is nothing to buy, license, or roll out; the work is turning it on and telling people it exists.
• Gmail, Docs, Sheets, Meet. Drafts in the inbox, a Sheets analysis, a Meet summary, Drive search: the assistant is inside the document rather than beside it.
• The low end. $4.99 for Google AI Plus and a broad free tier for a one-person shop; Microsoft's consumer paid path is $19.99.
• One bill and one admin console for the suite and the assistant.

Where Copilot is better

• The Microsoft-native office. If your company lives in Outlook, Teams, and Excel, Microsoft 365 Copilot is the only assistant that sits inside all three with your tenant's permissions behind it.
• Teams meetings. Recaps, action items, and "what did I miss" inside the meeting tool your company actually uses.
• Excel at depth. For the finance seat, Copilot in Excel against the workbook is the strongest single reason to buy the add-on for that one person.
• The free chat is real. Copilot Chat costs nothing on a business subscription, which makes "try it before you license it" the default path.

If Excel is the reason you are leaning toward Copilot, check which seat you are buying first. The full Copilot in Excel comes with the Microsoft 365 Copilot add-on, or with Microsoft 365 Premium at $19.99 a month for one person. What it does against a workbook is in Copilot for Excel.

Gemini vs Copilot by the job

• Email triage and replies: whichever suite holds the inbox. Gemini in Gmail; Microsoft 365 Copilot in Outlook (the paid add-on, not Copilot Chat).
• Meeting notes: Gemini in Meet at no extra cost; Copilot in Teams on the add-on.
• Spreadsheet analysis: Gemini in Sheets; Copilot in Excel is the better tool and costs $21 to $30 for that seat.
• Long documents, proposals, anything that has to sound like the company: neither is the best tool; see the third option below.
• One person, tightest budget: the free Gemini app or the free consumer Copilot, then Google AI Plus at $4.99 if you want a paid tier.

The data question, by plan rather than by vendor

The same rule as every assistant comparison on this site: the plan you buy is the data policy. Google's business terms keep Workspace content out of model training, and Microsoft 365 Copilot works inside your tenant's permissions under your company's Microsoft 365 agreement. The trap at both is the free consumer product doing business work. The consumer Copilot in Windows and Edge is not covered by your organization's Microsoft 365 agreement and has no access to, or protection for, your company's files, and the consumer Gemini app has its own settings to check before anyone pastes client work into it. Give people the business version of whichever assistant you pick, and treat the free apps as public.

The third option: a $20 Claude seat for the people who write

Every time I run this comparison for a client, the same thing happens. The suite's assistant is good enough for the whole company and costs nothing extra (Gemini) or nothing extra at the chat tier (Copilot Chat). Then two or three people, the proposal writer, the bookkeeper, the person who builds the procedures, need more than the suite offers, and the answer for them is not the rival suite's assistant, which they cannot use inside their own apps anyway. It is Claude Team at $20 a seat billed annually ($25 monthly) for 2 to 150 people, with no-training terms by default, a Microsoft 365 connector for the Microsoft office, and Google Drive connectors for the Google one. I made the Claude-versus-each case separately on Claude vs Gemini and Copilot vs Claude for business; the short version is that Claude wins the document and the agent, and the suite wins the inbox and the meeting.

The business-owner answer

Do not switch suites for an assistant; the suites differ more than the assistants do. If you are on Google Workspace, turn Gemini on today, it is already in the price. If you are on Microsoft 365, use Copilot Chat everywhere for free, then buy the Microsoft 365 Copilot add-on for the finance seat and the meeting-heavy seats only, at $21 to $30 each. Then put Claude Team in front of the two or three people whose output is the document. The four-vendor version of this call, with ChatGPT in it, is on best AI for small business. If you would rather have the assistant, the connectors, and the first three workflows installed than argued about, the Claude for Small Business install does that in about two weeks, from $4,500; the $397 Playbook is the do-it-yourself version. The assistant choice is the smallest AI decision on your list. What runs on top of it is the one that pays.
