Microsoft Copilot for SMEs: Is It Worth the Investment?

Microsoft Copilot has been one of the most talked-about technology launches in recent years. Built on large language model (LLM) technology and integrated directly into the Microsoft 365 apps your team already uses — Word, Excel, Outlook, Teams, PowerPoint — it promises to transform how people work. But at £24.70 per user per month (on top of your existing Microsoft 365 licence), is it genuinely worth it for a small or mid-size business?

We've been deploying Copilot for clients since its general availability launch in late 2024. Here's an honest breakdown of what it does well, where it falls short, and how to decide whether it's right for your business.

What Is Microsoft 365 Copilot?

Microsoft 365 Copilot is an AI assistant embedded into the Microsoft 365 suite. It uses OpenAI's GPT-4 model combined with your organisation's data in Microsoft Graph (emails, documents, chats, calendars) to generate content, summarise information, and automate repetitive tasks.

Key capabilities include:

• Word: Draft documents, rewrite sections, summarise long reports, and change the tone of existing text
• Excel: Analyse data using natural language prompts ("What were our top 5 products by revenue last quarter?"), generate formulas, create charts, and identify trends
• Outlook: Summarise email threads, draft replies, prioritise your inbox, and extract action items from conversations
• Teams: Generate meeting summaries with action items, catch up on missed meetings, and ask questions about discussion points you missed
• PowerPoint: Create presentation drafts from Word documents or prompts, add relevant imagery, and restructure slides

What It Costs

Microsoft 365 Copilot is an add-on licence priced at £24.70 per user per month. This is on top of your existing Microsoft 365 subscription. To use Copilot, you need one of the following base plans:

For a 20-person team on Business Standard, adding Copilot for all users would cost an additional £494 per month (£5,928 per year). That's a significant investment for a small business, which is why the question of ROI matters.

Where Copilot Genuinely Delivers Value

Meeting Summaries in Teams

This is consistently the feature our clients rate highest. If your team has frequent meetings, Copilot's ability to automatically generate meeting notes with action items is genuinely useful. No more asking "Can someone take minutes?" — Copilot captures the discussion, identifies decisions, and lists follow-up actions attributed to specific people. For businesses running 10+ meetings a week, this alone can save hours.

Email Summarisation in Outlook

Staff returning from leave or switching between projects can use Copilot to summarise long email threads in seconds. For roles that handle high email volumes — sales, account management, operations — this removes the friction of catching up and reduces the risk of missing important details buried in a 30-message chain.

First Drafts in Word

Copilot is effective at generating first drafts of standard business documents: proposals, reports, policies, or meeting agendas. It won't produce a polished final version, but it will give you a solid starting point that's faster than staring at a blank page. For businesses that produce a lot of written content, the time saving on initial drafts is tangible.

Where Copilot Falls Short

Excel Is Still Limited

Despite the impressive demos, Copilot in Excel is the weakest link. It struggles with complex spreadsheets, pivot tables, and workbooks with multiple sheets. For simple data analysis and chart creation it's fine, but if your team relies on advanced Excel functionality, don't expect Copilot to replace that expertise.

Data Quality Matters

Copilot is only as good as your underlying data. If your SharePoint is disorganised, your Teams channels are cluttered, and your email practices are inconsistent, Copilot will reflect that chaos back at you. Businesses with well-structured data get significantly more value. Before deploying Copilot, consider investing time in organising your document libraries and archiving old content.

It Can Hallucinate

Like all LLM-based tools, Copilot can generate plausible-sounding content that is factually incorrect. It might reference a meeting that didn't happen or attribute a statement to the wrong person. Every output needs to be reviewed before use. This isn't a "set and forget" tool — it's an assistant that requires supervision.

Should Your Business Invest?

Our honest recommendation:

• Yes, if: Your team lives in Microsoft 365 (especially Teams and Outlook), you have good data hygiene, and you have roles that involve heavy document creation, email management, or frequent meetings
• Start small: Don't buy licences for everyone on day one. Start with 3-5 power users — the people who write the most, attend the most meetings, or handle the highest email volume. Measure their time savings over 30 days
• Hold off, if: Your team is small (under 5 people), you don't heavily use Teams meetings, or your Microsoft 365 environment is disorganised. Fix the foundations first

Getting Started with Copilot

If you decide to move forward, here's a practical deployment checklist:

1. Audit your data: Clean up SharePoint, archive old Teams channels, and review sharing permissions
2. Check licensing: Ensure pilot users are on a compatible Microsoft 365 plan
3. Set expectations: Train users on what Copilot can and can't do — managing expectations prevents disappointment
4. Review security: Copilot respects existing permissions, but it can surface data users have access to but may not know about. Review your data access policies
5. Measure impact: Track time saved on drafting, email management, and meeting follow-ups over the pilot period
