SharePoint Add-ins Development

MSOfficeAddin delivers custom SharePoint add-in development and SharePoint Framework (SPFx) web part development for enterprise organizations running Microsoft 365 and SharePoint Online. We build intranet solutions, document automation tools, approval workflows, and custom portal experiences that transform SharePoint from a file storage platform into a true enterprise productivity hub.

**SharePoint add-in development vs. SPFx web parts — which does your project need?**

SharePoint classic add-ins (provider-hosted and SharePoint-hosted) are still widely used in enterprises with existing investments, and we support their maintenance and migration. For new development, the SharePoint Framework (SPFx) is Microsoft's modern approach — our team builds SPFx web parts and extensions that render natively in the modern SharePoint interface with full support for Microsoft Graph, Azure AD, Teams integration, and Fluent UI.

**SharePoint development solutions we deliver:**

- **SPFx web parts** — custom React-based web parts embedded in SharePoint modern pages for dashboards, data displays, and interactive tools
- **SPFx extensions** — application customizers, field customizers, and command sets that extend the SharePoint interface
- **SharePoint intranet portals** — fully designed and developed departmental intranets, company news hubs, and employee experience portals
- **Document management add-ins** — custom metadata tagging, automated document routing, version control workflows, and approval flows
- **SharePoint + Microsoft Graph** — integrate SharePoint lists and libraries with Teams, Outlook, Excel, and external systems via Graph API
- **SharePoint automation workflows** — Power Automate flows connected to SharePoint events and custom SPFx trigger points
- **SharePoint + Azure AD** — role-based access control with Microsoft Entra ID for secure, permission-layered SharePoint solutions
- **Legacy SharePoint add-in migration** — modernize provider-hosted or SharePoint-hosted classic add-ins to SPFx
- **SharePoint list and library customization** — custom list forms, filtered views, and column formatting using SPFx and JSON
