SharePoint Explained for Small Businesses

What SharePoint actually is

SharePoint is Microsoft's document platform and intranet. Think of it as a shared, structured filing cabinet for the business, with built-in permissions, versioning, and search. Every Team you create in Microsoft Teams is quietly backed by a SharePoint site. Every file shared in Teams lives in SharePoint.

SharePoint vs OneDrive vs Teams

• OneDrive is for individual work you own the files
• SharePoint is for shared / team work the business owns the files
• Teams is a collaboration app that uses SharePoint underneath for files
• If a file matters to more than one person, it belongs in SharePoint (via Teams), not OneDrive

How small businesses typically use SharePoint

• Department document libraries (Finance, Operations, HR, Sales)
• Client / project sites with restricted access
• A company intranet with policies, forms, employee directory, and news
• Structured lists (asset registers, vendor lists, on-call schedules)
• Templated document workflows for proposals, invoices, or onboarding

Structure it before you fill it

The biggest SharePoint mistake is creating one giant 'Company Files' site and dumping years of shared drive content into it. Design a flat, purposeful site architecture usually one hub site with department sites and project sites beneath it. Restrict site creation the same way you restrict Teams creation.

Permissions the simple way

• Use Microsoft 365 groups (which are also Teams) for permissions, not individual users
• Avoid item-level permissions except in rare cases they're impossible to audit
• Use private channels or separate sites for confidential content, not permission overrides
• Review external sharing per site, not just tenant-wide

Migrating from a file server

Most SMBs come to SharePoint from a legacy file server. Do not do a lift-and-shift. Take the migration as an opportunity to redesign structure, purge obsolete content, and remove duplicate copies. Migration tools handle the actual copy the design is where the value is.

Common mistakes

• Dumping the entire shared drive into a single site
• Setting item-level permissions instead of using group-based access
• Turning off versioning to 'save space' (versioning is essentially free)
• Not using metadata or standardized columns for high-volume libraries
• Ignoring external sharing settings until sensitive data leaks

When to call an IT provider

A structured SharePoint rollout for a 25-user business is typically a two to four week engagement. Getting the information architecture right the first time saves years of cleanup and frustrated users.
