Choose on the work your people actually do and where your data already lives, then train them to build on it. WRITTENOctober 2026 READING · Ten minutes FOR · CEOs, COOs, CFOs, IT and operations leads RELATES TO[Hands-on AI training](https://anywayventures.com/ai-training) The honest answer to Copilot vs ChatGPT vs Claude for business is that you should choose by workload and by where your data already lives, not by whichever model topped a benchmark this month. If your business runs on Outlook, Teams and SharePoint, Microsoft 365 Copilot is the natural default; if your work is heavy reading, analysis and drafting, Claude earns its seats; ChatGPT is the most flexible general assistant and the one your staff probably already use at home. Then the part most businesses skip: train people to build on the tool you chose, on their own work. I've rolled these tools out, and watched others roll them out, in enough businesses to have firm views. The tool choice matters less than people think. What matters is whether anyone changes how a piece of work gets done. The best tool is the one your people can build on by Friday, inside the systems they already use. > The best tool is the one your people can build on by Friday, inside the systems they already use. ## Copilot vs ChatGPT vs Claude: what each one actually is Before comparing, it helps to be clear what you are buying, because the names hide quite different products. Microsoft 365 Copilot (Microsoft has started calling it simply Microsoft Copilot) is an assistant built into Outlook, Teams, Word, Excel, PowerPoint and SharePoint. Its main advantage is not the model. It is that it can see your mail, meetings and files under the permissions you already have in Microsoft 365, so it can summarise the thread you were copied into, draft from last quarter's deck and pull notes from the Teams call. Every eligible Microsoft 365 subscription also includes a free tier, Copilot Chat, which is a web-grounded chat assistant without the deep access to your files. ChatGPT Business and ChatGPT Enterprise are OpenAI's workplace plans. ChatGPT is a standalone assistant with connectors into common business apps, custom GPTs that a team can set up for a repeated task, and strong general ability across writing, analysis, images and voice. It is the tool most staff have already used personally, which cuts both ways: low training friction, and a habit of pasting things into personal accounts that you will want to stop. Claude Team and Claude Enterprise are Anthropic's workplace plans. Claude has built a reputation for long-document work, careful reasoning and writing that holds a voice, and for coding and building. Projects let a team keep a shared set of documents and instructions for a piece of work. Many finance, legal and strategy teams I meet prefer it for anything that involves reading a lot before writing a little. Gemini sits inside Google Workspace. If your business runs on Gmail, Docs, Sheets and Drive, Gemini is to you what Copilot is to a Microsoft business. Google's [Workspace pricing page](https://workspace.google.com/intl/en_uk/pricing) shows Gemini access across its business plans, limited on Starter and expanded on Standard and above. One complication worth knowing: the lines are blurring. Microsoft now offers Anthropic's Claude models inside Copilot, in Researcher, Copilot Studio and the Office apps. According to [Microsoft's own documentation](https://learn.microsoft.com/en-us/microsoft-365/copilot/connect-to-ai-subprocessor) , UK customers have the Anthropic models disabled by default and an administrator has to opt in. So "Copilot or Claude" is sometimes the wrong question for a Microsoft shop. ## ChatGPT Enterprise vs Copilot: what it costs in the UK Prices change often and vary by contract, so treat what follows as a snapshot I checked on vendor pages in October 2026, and check the current page before you budget. Product Plan List price I could verify (October 2026) Microsoft 365 Copilot Copilot Business add-on (smaller organisations) £16.10 per user per month, paid yearly; Microsoft is running a first-year promotion at £13.80 for new annual commitments made between 1 July and 31 December 2026 Microsoft 365 Copilot Enterprise add-on £23.10 per user per month, paid yearly Microsoft 365 Copilot Copilot Chat Included with eligible Microsoft 365 subscriptions Claude Team, standard seat US$20 per seat per month billed annually, US$25 monthly Claude Team, premium seat US$100 per seat per month billed annually, US$125 monthly Claude Enterprise US$20 per seat per month billed annually, plus usage at API rates ChatGPT Business and Enterprise Not stated here: I could not load OpenAI's pricing page to verify it. Check it directly Gemini Included in Google Workspace plans Varies by Workspace plan; check Google's page Sources: [Microsoft 365 Copilot business pricing](https://www.microsoft.com/en-gb/microsoft-365-copilot/pricing) , [Microsoft 365 Copilot enterprise pricing](https://www.microsoft.com/en-gb/microsoft-365-copilot/pricing/enterprise) , [Claude pricing](https://claude.com/pricing) . Copilot's figures are add-ons on top of a qualifying Microsoft 365 licence. Claude quotes in US dollars. Enterprise contracts for any of these are usually negotiated. The list price is rarely the deciding number. A £23 seat used daily by a finance analyst is cheap. The same seat used twice at launch is expensive. If you already have licences, the [one-week licence audit](https://anywayventures.com/insights/you-bought-the-licences-and-nothing-changed) will tell you your real cost per active user before you add anything. ## Which AI tool should my team use? A decision table Start with two questions. Where does the work, and the data it depends on, already live? And what kind of work is it: quick drafting and summarising, deep reading and analysis, or building something that runs on its own? Your situation Sensible default Why Watch out for Microsoft 365 heavy: Outlook, Teams, SharePoint, Excel Microsoft 365 Copilot Works where the files and meetings already are, under existing permissions Messy SharePoint permissions mean Copilot can surface files people shouldn't see. Tidy access first Google Workspace business Gemini in Workspace Same logic: it lives in Gmail, Docs, Sheets and Drive Check which Workspace plan includes the Gemini features you need Heavy document and analysis work: finance, legal, strategy, bids Claude for the specialist team, alongside the company default Long documents, careful reasoning, consistent drafting Don't let documents drift into personal accounts; give the team proper business seats Building automations and internal tools Whatever connects to your systems: Copilot Studio and Power Automate in a Microsoft shop; Claude or ChatGPT with Zapier, Make or n8n elsewhere The value comes from wiring the model into your systems, not from the chat window Each build needs an owner, a data check and a note on what to do when it breaks Small team, mixed apps, no strong platform ChatGPT Business or Claude Team Flexible, quick to start, low admin Agree data rules on day one; it's easy for usage to sprawl Notice that the answer for building is "it depends what you already run". That's deliberate. An automation that reads supplier emails and updates the ERP lives or dies on the connection to the inbox and the ERP. The model inside it matters much less, and most of the serious options can now be swapped in. ## Claude for business: when it earns a separate seat Most of the mid-market businesses I work with are Microsoft shops, so Copilot is usually the company-wide default. The question I then get is whether some teams should also have Claude. My test is simple. If a team spends a lot of its week reading long material and producing careful written output, it probably should. Finance teams writing month-end commentary from a ledger export and a budget pack. Legal and commercial teams comparing a supplier's contract against your standard terms. Bid teams pulling a forty-page tender into a structured response. Strategy and PE-facing teams preparing board papers. These are the jobs where the quality of the reasoning shows, and where people tell me they get noticeably better first drafts. The cost arithmetic usually works. Take an illustrative finance team of six on Claude Team standard seats at US$20 a month each, about US$1,440 a year. If month-end commentary takes each of three analysts a day and a half, and a good first draft cuts that to half a day, that's three analyst-days a month returned. You don't need a generous day rate for that to pay back several times over. Measure it properly, though: the method in [measuring AI ROI](https://anywayventures.com/insights/measuring-ai-roi) applies to seats as much as to automations. ## Many businesses end up with more than one The purist answer is to pick one tool and standardise. In practice, many businesses end up with two, and I think that's fine if it is a decision rather than an accident. The pattern that works: one company-wide default (usually Copilot or Gemini, because they come with the office suite) for everyone, plus a smaller number of specialist seats for the teams whose work justifies them. What doesn't work is finance buying Claude on a card, sales expensing ChatGPT and IT rolling out Copilot, with nobody owning the data rules across all three. So whatever you choose, put three things in place at the same time: One approved list. Which tools are allowed, for whom, on which plan. Personal accounts are not on it. One data rule. What can go into which tool. I've published an [AI policy template for UK businesses](https://anywayventures.com/insights/ai-policy-template-uk) with a traffic-light table you can copy. One owner. A named person who reviews usage and seats before each renewal. ## Copilot training and Claude training for finance: train on what they'll build Here's where most rollouts fall over. The tool arrives with a launch email and a lunchtime webinar on prompting. People enjoy it. On Monday the work looks the same. The national figures match what I see. The [ONS](https://www.ons.gov.uk/businessindustryandtrade/business/businessservices/articles/artificialintelligenceinukbusinesses/2023to2026) reported in July 2026 that around 35% of UK businesses with ten or more employees use at least one AI technology, but only 11% say more than half their workforce has had AI-related training. The government's own [AI skills announcement](https://www.gov.uk/government/news/free-ai-training-for-all-as-government-and-industry-programme-expands-to-provide-10-million-workers-with-key-ai-skills-by-2030) in January 2026 cited research that only 21% of UK workers feel confident using AI at work. Buying the tool is the easy part. Good training is specific to the role and the tool. Each person brings one repetitive task from their own week and leaves with something that handles it. Here's what that looks like by team. Team On Microsoft 365 Copilot On ChatGPT On Claude Finance Month-end variance commentary drafted in Excel and Word from the ledger export A custom GPT that checks expense claims against the policy Board pack commentary and a budget-vs-actual narrative from a long pack of exports Operations A Power Automate flow that pulls delivery dates from supplier emails into a tracker A supplier email triage assistant with drafted replies A procedures assistant that answers staff questions from your own SOPs, with sources Sales Call notes from Teams meetings turned into CRM updates and follow-ups Account research briefs before a first meeting First-draft proposals from the brief, the price list and past winning bids HR A handbook assistant in Teams that answers policy questions Job descriptions and interview question sets from a role brief Policy redrafts checked against current guidance, with changes explained Customer service Ticket summaries and drafted replies in Outlook Classifying and routing incoming tickets Complaint responses that need care and a consistent tone Leadership Meeting recaps and actions across Teams Market and competitor research Reading a long report or data room document and producing a two-page summary None of those is glamorous. All of them are things a person can build in an afternoon with help, and use the next morning. That's the test I'd hold any Copilot training or ChatGPT course to: did every attendee leave with something that works on their own job? ## How to run the decision in two weeks If you're starting from scratch, or reconsidering what you have, this is the sequence I'd follow. Week one, days one and two. List the ten most repetitive written or analytical tasks across finance, operations, sales and HR. Note where the data for each lives. Week one, days three to five. Pick the default that matches your platform. Give five or six people from different teams trial seats on any specialist tool you're considering. Week two. Each trial user runs their real task in both the default and the alternative, side by side, and scores the output. Not a demo prompt. Their actual Tuesday. End of week two. Decide the default, decide which teams (if any) get specialist seats, publish the approved list and data rules, and book the training around the tasks people listed. Two weeks, real work, and a decision you can explain to the board. If the board wants more than that, the [questions boards should ask about AI](https://anywayventures.com/insights/board-questions-about-ai) are a good frame for the update. ## The tool is the easy part Whichever you choose, the result depends far more on what people build with it than on the logo. A Copilot rollout where the finance team built their month-end commentary tool will beat a Claude rollout where nobody changed anything, and the reverse is just as true. So choose quickly, on workload and data, accept that you may end up with two, and spend your effort on the people. That's what our [hands-on AI training](https://anywayventures.com/ai-training) is for: in person, at your offices, up to twelve people at a time, each building a working tool on their own job, in whichever of these tools you already pay for. ## Questions ### Is Microsoft Copilot better than ChatGPT for business? Neither is better in general. Copilot is the stronger default if your documents, email and meetings already live in Microsoft 365, because it works inside Outlook, Teams, Word and Excel under your existing permissions. ChatGPT tends to suit teams who want a flexible general assistant across many apps and like building custom GPTs. Decide on where your data lives and the jobs people do every week, then trial both with real work. ### What is Claude best used for in a business? Claude is strong on long documents, careful analysis and writing that needs a consistent voice: contracts, board papers, policy work, financial commentary and anything that involves reading a lot before writing a little. Technical teams also use it for building automations and internal tools. Many Microsoft-based businesses can now reach Claude models inside Copilot too, though for UK tenants an administrator has to switch that on first. ### Should a business pay for more than one AI tool? Often, yes, but deliberately. A common and sensible pattern is one company-wide default assistant for everyone, plus a smaller number of specialist seats for the teams that do heavy analysis, writing or building. What goes wrong is three tools bought by three departments with no shared data rules. Agree one approved list, one data policy and one owner, and review seat usage before every renewal. ### What AI training should staff get after we choose a tool? Train people on the work they will do with it, not on the tool's menu. The most effective sessions have each person bring a repetitive task from their own week and build something that handles it, in the tool you licence, with the safe-use rules agreed for your business. Short prompting webinars raise awareness. Building something real is what changes how people work on Monday. Brannan Coady Founder of Anyway Ventures.
