Should you build a custom SharePoint intranet or buy an out-of-the-box solution? Compare pros, cons, cost, and fit for your organization.

Build vs. Buy SharePoint Intranet: Which Path Is Right for You?

Introduction

When it comes to intranets, organizations often face a choice: build a custom solution on SharePoint or buy an out-of-the-box platform (e.g., Simpplr, Igloo, Staffbase). Both paths have merits. This article helps you decide which fits your organization.

Build: Custom SharePoint Intranet

Pros

  • Full control – Design, structure, and features match your processes and culture.
  • Microsoft 365 integration – Native connection with Teams, Outlook, OneDrive, Power Automate.
  • No per-seat licensing – You already pay for SharePoint via M365; custom development is a one-time or project-based cost.
  • Scalability – Grows with your organization without switching platforms.
  • Compliance – Data stays in your Microsoft 365 tenant; easier to meet regulatory requirements.

Cons

  • Upfront development time – Typically 2–5 weeks for a solid custom intranet.
  • Requires expertise – You need a partner or internal team with SharePoint/SPFx skills.
  • Ongoing maintenance – You own updates, governance, and support.

Best for

  • Organizations already on Microsoft 365
  • Teams with specific workflows, terminology, or compliance needs
  • Companies that want to avoid recurring SaaS fees

Buy: Out-of-the-Box Intranet Platform

Pros

  • Faster launch – Pre-built templates and features can go live in days or weeks.
  • Less technical burden – Vendor handles updates, hosting, and support.
  • Rich features – Many platforms offer analytics, employee apps, and integrations out of the box.

Cons

  • Recurring costs – Per-seat licensing can add up for large organizations.
  • Less flexibility – Harder to match unique processes or deep M365 integration.
  • Vendor lock-in – Migrating away can be costly and complex.
  • Generic experience – May not reflect your brand or workflows as closely.

Best for

  • Organizations that need to launch quickly with minimal IT involvement
  • Teams that prefer a managed service over in-house development
  • Companies without strong Microsoft 365 adoption

Hybrid: Viva Connections + Custom Sites

Microsoft’s Viva Connections offers a middle ground: a Teams-based entry point that can link to custom SharePoint sites. You get a quick launch experience plus the flexibility of SharePoint for deeper needs.
