Microsoft 365 Copilot: What It Is and Whether It's Worth It

Microsoft 365 Copilot is the AI assistant built into the Office apps, and it has been talked about endlessly. As a CFO, I am naturally sceptical of anything sold on hype, so let me give you a grounded view: what it does, what it costs, and whether it is worth it for a typical business today.

What Copilot actually does

Copilot is an AI assistant woven into the apps you already use:

• In Word - draft, summarise and rewrite documents
• In Excel - analyse data, spot trends and build formulas from plain-English requests
• In Outlook - summarise long email threads and draft replies
• In Teams - summarise meetings, capture actions and catch you up on what you missed
• In PowerPoint - turn a document into a first-draft deck

The key difference from generic AI tools is that Copilot works on your business data - your documents, emails and meetings - because it is built into your Microsoft 365 environment.

Where it genuinely helps

The strongest, most reliable wins are:

• Summarising - long threads, documents and meetings condensed in seconds
• First drafts - getting past the blank page, then editing
• Catching up - quickly getting up to speed after time off or in a busy week

These save real time on the admin that eats into everyone's day.

The honest caveats

• It costs extra. Copilot is a per-user add-on on top of your existing licence, and it isn't cheap. The maths only works if it genuinely saves time.
• It needs good data hygiene. Copilot can surface anything a user already has access to - so if your file permissions and sharing are messy, it can surface things it shouldn't. Tidy security first.
• It's an assistant, not an oracle. Output needs checking. It accelerates work; it doesn't replace judgement.

The CFO's verdict

For businesses with knowledge workers who spend a lot of time writing, summarising and in meetings, Copilot can pay for itself - but only if you commit to using it and your data is in good order. For lighter users, the per-seat cost is hard to justify yet. My advice: pilot it with a small group, measure the time saved honestly, then decide whether to roll it out.

Make sure you're ready first

Before adding Copilot, get your licensing, security and file governance in shape - otherwise you're paying for AI on top of a messy foundation. Our IT Support service helps you prepare and pilot Copilot sensibly. Request a callback to talk it through.
