Key takeaways
- Copilot Chat is included for Microsoft 365 business users and is a capable baseline.
- The paid licence is about grounding: Copilot working across the user's own email, meetings and files.
- The people who benefit most are those whose job is managing their own inbox, calendar and documents.
- Fix permissions before anyone gets a paid licence.
Microsoft's naming makes this harder than it should be. There is Copilot Chat, which most business users already have, and there is Microsoft 365 Copilot, the paid licence, sold to smaller organisations as Copilot Business. The question every Microsoft business faces is who needs the upgrade. Usually it is fewer people than the sales conversation suggests.

| Grounded in the web | Yes | Yes |
| Works with files the user provides | Yes | Yes |
| Reasons across the user's mailbox, calendar, chats and meetings | No | Yes |
| Reasons across SharePoint and OneDrive content the user can access | Limited | Yes |
| Deep features in Word, Excel, PowerPoint, Outlook, Teams | Some | Full |
| Agents | Available, some billed by usage | Available, Copilot Studio usage metered |
A three question test
For each person, ask:
- Is most of their day in email and meetings? Managers, partners, directors and assistants usually say yes.
- Do they regularly need to find or combine information spread across their own files and threads? Account managers and project leads often do.
- Would they use it at least three times a week? If you are not confident, they are not ready for a paid seat yet.
Two yes answers including the third: give them a paid licence. Otherwise, Copilot Chat with good training is enough for now.
Getting more out of Copilot Chat
Most businesses under-use what they already have. Before buying paid seats:
- Make sure Copilot Chat is pinned and visible in the apps people use.
- Train people on three tasks from their own work: drafting, summarising an attached document, and preparing for a meeting.
- Set the usage policy so people know what is allowed.
- Watch the usage reports for a month. The people who use Chat most are your best candidates for paid seats.
Before any paid seats
Paid Copilot sees what the user can see. Overshared SharePoint sites and old organisation-wide links become a real exposure the day it is switched on. Work through fixing SharePoint permissions before Copilot first, then start with a pilot group.
Typical outcome: in a 50 person business, Copilot Chat for everyone and paid Copilot for eight to twelve people, reviewed after 90 days.

Frequently asked questions
Is Copilot Chat free?
Copilot Chat is included for Microsoft 365 business users at no extra per-user cost. It offers web-grounded chat with enterprise data protection and can work with files a user provides. Some agent features in Copilot Chat may be billed by usage.
What does paid Microsoft 365 Copilot add?
The paid licence lets Copilot work across a user's own Microsoft 365 data, including mailbox, calendar, Teams chats and meetings, OneDrive and SharePoint content they can access, and adds deeper Copilot features inside Word, Excel, PowerPoint, Outlook and Teams.
How much is Microsoft 365 Copilot for small business?
For organisations of up to 300 users, Microsoft sells Copilot Business, listed at 21 US dollars per user per month on annual terms, with promotional pricing during 2026 that varies by channel. Each user also needs a qualifying Microsoft 365 plan.
Should everyone get a paid Copilot licence?
Rarely. The paid licence is most valuable for people whose work centres on their own email, meetings and documents. Start with those people, measure use, and expand on evidence.
