You probably got an email about this. Microsoft changed how Copilot is sold to small businesses, your IT provider forwarded the announcement, and it had four different prices in it. You closed the tab.
Fair. Here’s the one-page version.
What actually changed
For most of the time Copilot has existed, adding it to a Microsoft 365 subscription meant buying a promotional add-on. Promos expire, which meant every conversation about AI came with a countdown clock attached.
On July 1, 2026, Microsoft made two of those bundles permanent products: Microsoft 365 Business Standard with Copilot and Microsoft 365 Business Premium with Copilot. Stable list pricing, no expiration date.
That is the actual news. Not a new feature – a pricing model that finally lets you budget for AI like you budget for anything else.
The four options, in plain English
All of these are for organizations with 300 users or fewer, which covers nearly every business we work with in Castle Rock. Prices are per user, per month.
Copilot Business on its own – $18
You keep whatever Microsoft 365 plan you already have and bolt Copilot onto it. This is the cheapest door in. Requires an annual subscription with annual billing, and the discounted rate runs through December 31, 2026.
For 20 people: about $4,320 a year.
Business Basic with Copilot – $21
Basic means web and mobile versions of Word, Excel, and PowerPoint – no installed desktop apps. Also an annual commitment, also discounted through the end of 2026.
For 20 people: about $5,040 a year.
Business Standard with Copilot – $23.50
Full desktop Office apps plus Copilot, in one permanent SKU. For most small businesses, this is the sensible default. No promo clock.
For 20 people: about $5,640 a year.
Business Premium with Copilot – $32
Everything in Standard, plus Microsoft Defender for Business, device management, and the advanced security controls. Also permanent.
For 20 people: about $7,680 a year.
One thing worth flagging: the two discounted options require annual billing, which means paying for the year up front. The permanent SKUs give you more flexibility on payment terms. If cash flow matters more than the per-seat rate, that difference is worth more than the few dollars a month.
The distinction that trips everyone up
There are three things with “Copilot” in the name and they are not the same product.
Copilot Chat is the one that is already included with most Microsoft 365 subscriptions. It is a chat window with enterprise data protection, and it works off public web data. It does not connect to your files, your email, or your Teams conversations. If you have tried Copilot and thought “this is just a chatbot,” this is almost certainly what you used.
Copilot Business is the paid SKU for companies under 300 users. This is the one that actually reaches into your organization’s content – summarizing a thread in Outlook, pulling numbers out of a spreadsheet, catching you up on a meeting you missed.
Microsoft 365 Copilot is the enterprise-licensed version, sold against E3 and E5 plans with no user cap.
The important part: as far as Microsoft describes it, Copilot Business is not a stripped-down edition. The core AI capabilities across Word, Excel, Outlook, PowerPoint, and Teams are the same. What differs is the licensing model, the 300-user ceiling, and the governance and compliance tooling – and that last one comes from your underlying Microsoft 365 plan, not from Copilot.
Translation for a 20-person company: you are not getting the discount version. You are getting the correctly licensed version.
When it is not worth it
We would rather tell you to wait than sell you 20 seats you do not use.
Your SharePoint permissions are a mess. This is the big one. Copilot only surfaces content a user already has permission to open – which sounds reassuring until you remember that half the small businesses we audit have a “Company” folder everyone can read. Copilot will not create a leak. It will make an existing one very easy to find. Clean up access first.
Your team does not live in Office. If most of the day happens in a line-of-business application, a POS system, or QuickBooks, Copilot has less to work with. The value scales with how much of the work already happens in Microsoft 365.
You are already on enterprise Copilot. You generally cannot switch to the Business offerings mid-term – you wait for renewal. Plan for it rather than trying to move now.
Nobody owns it. Twenty licenses handed out with no training becomes twenty unused licenses. Someone has to care whether people use it.
What we would tell a client here in Castle Rock
Do not buy 20 seats. Buy five.
Pick the people who write and summarize the most – whoever handles proposals, whoever runs the meetings, whoever spends their Fridays in spreadsheets. Give it 60 days. Ask them one question: did this save you time you can point at?
If the answer is yes, expand with evidence instead of a hunch. If it is no, you spent a few hundred dollars finding out, which is a bargain compared to a year of shelfware.
The pressure to buy the whole company in at once comes from the discount structure, not from anything about how the tool works. December 31 is a real deadline for the promotional rates, but a rushed 20-seat purchase that nobody adopts costs more than the discount saves.
Not sure which column you are in?
We will look at your current Microsoft 365 setup, tell you which of the four options fits, and give you an honest answer about whether your tenant is ready for it. Twenty minutes, no charge, and we are entirely willing to tell you to skip it.
