Whether you run a five-person office or a growing company with remote staff, Microsoft 365 gives you enterprise-grade software without the cost and complexity of on-premises infrastructure.Documentation Index

What’s included in Microsoft 365
Microsoft 365 bundles a broad set of applications and services. The core components you’ll use most are:Microsoft Teams
Chat, video meetings, and team channels in one place. Teams replaces scattered email threads and gives your staff a shared workspace for every project.
Exchange Online
Business email hosted in the cloud. You get your own domain addresses, shared calendars, and contacts — all managed without an on-site mail server.
SharePoint
A central intranet and document library for your organisation. Store, share, and co-author files with fine-grained permission controls.
OneDrive
Personal cloud storage for every user. Files sync automatically across devices and are accessible from any browser.
Office apps
Word, Excel, PowerPoint, and OneNote — available as desktop installs, web apps, and mobile apps on every plan.
Microsoft Copilot
AI assistance built into Teams, Outlook, Word, Excel, and more. Copilot drafts emails, summarises meetings, and generates content from your data.
Why Microsoft 365 works for small businesses
Investing in on-premises servers, software licences, and IT staff to maintain them is expensive and time-consuming. Microsoft 365 changes the economics.No large upfront hardware investment
No large upfront hardware investment
All compute, storage, and software updates live in Microsoft’s data centres. You pay a predictable per-user monthly fee instead of a large capital outlay for servers and licences.
Scalable as you grow

Add or remove user licences at any time. If you hire three people in January and need to reduce headcount in March, you adjust your subscription — no wasted software seats.
Access from any device, anywhere

Your team can open files, join meetings, and answer email from a laptop at the office, a phone on the road, or a browser at home. Microsoft 365 is designed for hybrid and remote work.

Choosing the right plan
Microsoft offers several tiers aimed at different business sizes and needs.- Microsoft 365 Business Basic
- Microsoft 365 Business Standard
Web and mobile versions of Office apps, Teams, Exchange Online, SharePoint, and OneDrive. A good starting point if most of your staff work in a browser and on mobile.
