What Is SharePoint? A Guide for Small Business Owners

If you use Microsoft 365, chances are you’ve seen SharePoint sitting in your app list, mostly ignored. Most business owners end up asking what is SharePoint at some point, without ever getting a straight answer.

Here’s that straight answer: what SharePoint actually does, real SharePoint use cases, and when your business is ready to start using it.

What is SharePoint, in plain terms?

SharePoint is Microsoft’s tool for storing, organizing, and sharing company information in one central place. If you’re wondering what is SharePoint compared to a normal shared drive, the difference comes down to structure. Everything is searchable, permission-controlled, and built to work with the rest of Microsoft 365.

Microsoft 365 SharePoint plans already include everything most small businesses need to get started, so there’s rarely an extra cost involved in unlocking it. It’s already sitting there, mostly unused.

Under the hood, SharePoint actually powers several things you might already use without realizing it. Every Microsoft Team has a SharePoint site behind it. Every shared document library lives on SharePoint. Even your company intranet, if you have one, is likely built on it.

Common SharePoint use cases for small businesses

SharePoint for business comes down to a handful of concrete jobs, not some abstract enterprise concept:

• Document libraries. A shared, version-controlled space for contracts, policies, templates, and project files, instead of scattered copies in email inboxes.
• Team sites. A dedicated space per department or project, with its own files, calendar, and task list.
• An intranet. A company homepage with announcements, HR documents, and links to the tools employees use daily.
• Permission control. Fine-grained rules over who can view or edit specific files or folders, which is hard to manage with email attachments or a shared drive.
• Workflow automation. Combined with Power Automate, SharePoint can trigger approvals, notifications, and routine tasks automatically.

SharePoint vs OneDrive vs Teams files: what’s the difference?

This is where most confusion starts, because all three look similar on the surface.

OneDrive is personal storage. It’s your own files, meant for you, with sharing as the exception rather than the rule. SharePoint is built the other way around: shared by default, meant for a team or the whole company. Teams files are actually SharePoint underneath. When you upload a file in a Teams channel, it’s stored in that team’s SharePoint site automatically.

A simple rule for SharePoint vs OneDrive: if a file belongs to one person, it lives in OneDrive. If it belongs to a team or the company, it belongs in SharePoint.

When your business doesn’t need SharePoint yet

SharePoint isn’t automatically the right move for every business. If you’re a small team of five people sharing files through Teams already, you’re likely using SharePoint’s basics without needing to touch it directly. Building out a full intranet or complex site structure too early just adds overhead nobody uses.

It becomes worth the setup once you notice real friction: people can’t find the right version of a document, sensitive files get shared over email, onboarding new employees means digging through scattered folders, or departments each have their own inconsistent way of storing information.

Getting started without overcomplicating it

Once you’ve answered what is SharePoint for your own team, the businesses that get the most out of it start small. One well-organized document library beats a sprawling intranet that nobody maintains. From there, you can expand into team sites, permission structures, and automation as the need actually arises.

This is also where a bit of guidance pays off. Setting up folder structures and permissions properly from day one saves a lot of cleanup later, and ties directly into a broader cloud versus on-premise strategy for your business. It also fits naturally alongside the collaboration tools covered in our piece on reducing meeting overload with smarter IT tools.

For the technical details straight from the source, Microsoft’s own SharePoint overview and the background on its history and architecture are both worth a look.

Frequently asked questions

What is SharePoint used for in a small business?

Mainly shared document storage, team sites, an internal intranet, and permission control over who can see or edit specific files.

Is SharePoint the same as OneDrive?

No. OneDrive is for personal files, while SharePoint is built for shared, team-based storage and collaboration.

Do I need SharePoint if I already use Teams?

You’re likely already using it without realizing it. Teams file storage runs on SharePoint in the background.

Is SharePoint difficult to set up?

The basics are simple. It gets more complex once you build custom sites, automated workflows, or detailed permission structures, which is where IT support helps.
