SharePoint Intranet Cost: Full Breakdown by Company Size (2026)
How much does a SharePoint intranet cost? Licensing, development, and support — broken down for small, mid-size, and enterprise companies. Realistic 2026 figures.
Introduction
One of the most common questions when planning a SharePoint intranet is: How much will it cost? For a 500-person company, the answer depends on licensing, scope of custom development, and ongoing support. This article outlines typical cost ranges and what drives them.
SharePoint Intranet Cost at a Glance
The total cost of a SharePoint intranet has three components: licensing (recurring), custom development (one-time), and ongoing support (recurring). Here’s how they add up by company size:
| Small (10–100 users) | Mid-size (100–500 users) | Enterprise (500+ users) | |
|---|---|---|---|
| M365 licensing / year | $7,000 – $50,000 | $50,000 – $240,000 | $240,000+ |
| Custom dev (one-time) | $3,000 – $12,000 | $15,000 – $40,000 | $40,000 – $100,000+ |
| Support / year | $0 – $6,000 | $6,000 – $24,000 | $24,000+ |
| Total Year 1 | $10,000 – $68,000 | $71,000 – $304,000 | $304,000+ |
| Total Year 2+ | $7,000 – $56,000 | $56,000 – $264,000 | $264,000+ |
Note: If your organization already has Microsoft 365 licenses, remove the licensing row — SharePoint is included. In that case, your cost is development + support only.
Licensing: Microsoft 365
SharePoint is included in Microsoft 365. For 500 users, you typically need one of:
- Microsoft 365 Business Standard – Lower cost, suitable for smaller or less complex needs.
- Microsoft 365 E3 or E5 – Enterprise plans with advanced security, compliance, and Power Platform. Most common for intranets with custom development.
Licensing is usually the largest recurring cost. At 500 users, this can range from roughly $10–40 per user per month depending on the plan—so $60,000–$240,000 per year for licensing alone.
Custom Development: One-Time or Project-Based
If you already have M365 licenses, the main variable cost is custom development:
- Light setup (2–3 weeks) – Basic hub, branding, a few sites. Often $5,000–$15,000.
- Standard custom intranet (3–5 weeks) – Hub architecture, employee directory, HR portal, document management. Often $15,000–$35,000.
- Enterprise implementation (6–12 weeks) – Multiple hubs, custom apps, migration, training. Often $35,000–$80,000+.
These are ballpark figures; actual costs depend on scope, partner rates, and region.
Ongoing Support and Maintenance
After launch, you may need:
- Content ownership – Internal (no direct cost) or outsourced.
- Technical support – Retainer for updates, fixes, and enhancements. Often $500–2,000/month depending on scope.
- Training and change management – One-time or periodic. Can be included in the project or billed separately.
Factors That Affect Cost
| Factor | Impact |
|---|---|
| Existing M365 licenses | If you already have E3/E5, no additional licensing for SharePoint. |
| Migration | Moving from legacy systems adds time and cost. |
| Custom apps | SPFx, Power Apps, or integrations increase development cost. |
| Multi-language / multi-region | More sites and content = more effort. |
| Governance and training | Often underestimated; plan for it. |
What Reduces SharePoint Intranet Cost
You can significantly lower the total cost with the right decisions upfront:
- Use existing M365 licenses. If you’re already on E3 or E5, SharePoint development is the only cost.
- Start with out-of-the-box features. Communication Sites and Hub Sites cover most needs without custom code. Reserve SPFx development for specific gaps.
- Avoid over-migrating. Not all content from old intranets needs to come over. Migrating only what users actively need cuts project time significantly.
- Train an internal owner. Having one person responsible for governance, permissions, and content updates reduces the long-term support cost.
- Prioritize features by usage. HR portal and document search are used daily; advanced analytics and custom dashboards can come in Phase 2.
How to Get a Tailored Quote
The best approach is a free consultation where you discuss:
- Current setup (M365, existing intranet, file shares)
- Desired features (HR portal, document management, news, etc.)
- Timeline and priorities
From there, a partner can provide a realistic quote for development and support.
Conclusion
For a 500-person company, a SharePoint intranet typically involves $15,000–$80,000 in custom development (one-time) plus M365 licensing (recurring) and optional ongoing support. The exact number depends on scope and requirements.
