Does SharePoint Embedded need its own licence?

Yes. SharePoint Embedded is a separate, consumption-based offering for developers building file storage into their own applications — it is billed by usage (storage and API calls) through Azure, not included in standard Microsoft 365 or SharePoint Online per-user licensing.

Why it's licensed differently

• SharePoint Embedded targets ISVs and internal developers building a custom app's storage layer, not end users browsing a SharePoint site.
• Its containers don't show up in the regular SharePoint admin center or the standard SharePoint Online storage pool.
• Billing follows Azure-style consumption metrics rather than a flat per-seat cost.
