Microsoft Copilot for small businesses.

If your team already lives in Outlook, Word and Teams, Copilot is the AI tool you will be asked about first, usually by someone who has seen a demo. It sits inside the apps they already use, which is its real advantage and the reason it is one of the first tools we cover in training.

This note covers what it genuinely does well, where it falls short, and how to decide whether it is worth the licence for your team.

What Copilot actually is

What you are buying is a licence level, not a separate product, and that is the first thing to get straight. Copilot Chat already comes with most business subscriptions. Without the paid add-on it will help you write, search the web, and work on files you upload to it by hand, but it cannot reach into your own business: not your mail, not your calendar, not your files or chats. The add-on is what opens that up, across the emails, meetings, chats and files you already have permission to see, plus the fuller Copilot inside Outlook, Word, Excel, PowerPoint and Teams.

The Microsoft 365 Copilot app is where Chat, Search, Agents, Notebooks and Create all sit, and Microsoft is increasingly treating it as the front door. It is not a third kind of Copilot, though. It is another place to use the one you are paying for, and it is what a demo will show you.

For most small teams the licence still earns its keep inside the apps people already have open, rather than in another window they have to remember to visit.

That access is the point. A chat tool with no connection to your business starts from a blank page. Copilot starts from your inbox.

Where it earns its keep

• Outlook. Summarising long email threads and drafting replies in your tone. For most small businesses this alone justifies the trial.
• Word. First drafts of proposals, letters and policies from a short brief, and rewrites of existing text.
• Teams. Meeting recaps with actions for people who could not be there, as long as the meeting was transcribed and your admin has turned the feature on.
• Excel. Explaining formulas and spotting patterns, and now building and reworking whole spreadsheets on its own: formulas, PivotTables, cleaning up messy data, and analysis in Python. Microsoft launched this as Agent Mode and now calls it Edit with Copilot, so you will see both names about. Excel used to be the weakest of the four. It is not any more.

That multi-step way of working is no longer an Excel-only thing either. Word and PowerPoint can now take on jobs with several steps in them inside the app, rather than only producing a first draft for you to fix.

Finding what you already know

With the paid add-on, Copilot searches across your own mail, meetings, chats and files, and only the ones you already have permission to open. Ask what was agreed about a contract and it can pull the answer out of a Teams thread from March along with an attachment nobody remembers filing.

In a business where the answer usually does exist somewhere but nobody can find it, this is often worth more than the drafting. It is also the honest reason to reach for Copilot rather than ChatGPT or Claude on an internal question. Both of those can be connected to work systems now, and they are the better writers in places. Neither arrives already joined up to your Microsoft 365.

Where it falls short

Copilot is only as good as the data it can reach. That used to mean Microsoft 365 and nothing else, and that is no longer true: Copilot connectors can bring in other systems you run, SaaS platforms and internal sites, and it can ground answers in the open web.

The limit is still real, it has just moved. Anything nobody has connected or indexed stays invisible to it. Out of the box it will not know your prices, your processes or your house style, because those live in people's heads, in a system nobody has pointed it at, or in a folder nobody told it about.

It also still gets things wrong. Every output needs a human check before it goes out. That is not a Copilot problem, it is an AI problem, and it is exactly what good training teaches your team to do quickly.

Closing that gap

You have options, and they split into two.

Microsoft offers Agent Builder and Copilot Studio for different agent scenarios. Licensing and usage charges depend on who uses the agent and how it is deployed. Check the current licensing terms and price your actual scenario before committing.

Or you keep the context outside Microsoft and feed it in, so what the business knows is captured once and is there in Copilot, Claude and ChatGPT together, rather than locked to whichever tool somebody happened to type it into.

What it costs

Compare a bundle that includes Copilot with adding it to an eligible Microsoft 365 subscription. Check the total subscription cost, commitment period, VAT and renewal terms. See Microsoft’s current UK plans and prices; promotions and plan combinations can change.

Get the exact plan name and eligibility confirmed when requesting a quote. Compare the features your team needs rather than assuming that similarly named Copilot plans cover the same work.

Treat every one of those numbers as the starting point for your own quote, not as a fact. Microsoft sets these prices, changes them, runs promotions and varies them by plan and by how long you commit for. Check its site on the day you buy, and get the quote in writing.

The arithmetic is the part that does not move. Whatever the per-seat figure turns out to be, ten licences is a low-thousands-a-year commitment and a hundred is a five-figure one, so the bigger the team, the more the total is worth a proper look before you commit to it.

The test underneath it does not change with size. It is not whether the licence is cheap, it is whether each licensed person saves more than an hour or two a month. For people who live in Outlook and Word, they usually do. What size does change is how many of your people that actually describes. In a sixty-person business it is rarely sixty, and a seat for everyone is how you end up paying for licences nobody opens.

Cowork, when a draft is not enough

Everything so far is Copilot helping with one job at a time. Copilot Cowork is a different proposition. You give it an outcome that takes several steps, it works out a plan and carries it out, and it can take actions across Microsoft 365 rather than just handing you a first draft. You still have to check what it did. That part never changes.

Two things to know before anyone gets excited. You need the base Copilot licence first, so this is an addition to the price above and not an alternative to it. And Cowork itself is metered, in Copilot Credits, bought either pay-as-you-go or as a prepaid annual pool. No credits come bundled with the licence. That makes it a second line on the bill, and one that moves with how much you use it, so work out what a normal month looks like before you switch it on for a team.

It is worth a look if your people have outgrown asking for drafts and want whole tasks taken off them. It is not where to start.

Compare alternatives on the same basis. Claude’s plan prices, usage limits and any extra usage charges matter as well as the headline subscription. Check Claude’s current plans and pricing for your region rather than relying on a converted sterling estimate.

So both put either a limit or a price on heavy agentic work. They just package it differently. Compare the cost of the jobs your people will actually run, not the subscription line.

How to decide

Do not buy licences for everyone on day one. Pick the two or three people who spend the most time on email and documents, run a one-month trial, and measure what changed. Then decide with numbers rather than a hunch.

That is the approach we take in training: your team learns the free tools first, sees what Copilot adds, and leaves knowing exactly which licences are worth paying for.

Last reviewed August 2026. Copilot moves fast, and pricing and features both change without much warning. Check Microsoft's current pages before you rely on any figure here.

Written with Claude, then steered, cut and checked by me. I answer for it.
