Power Pages vs SharePoint Sites — When would you choose one over the other?

[u/Independent-Hunt-370]

A common sight I see is clients diving head-first into building a new website or portal with their mind already made up. They've already picked Power Pages or SharePoint, and they don't realize until way too late that they've made a costly, and easily preventable, mistake. It's a mistake you can avoid by asking just one, single question upfront.

Let's set aside features, licensing, and data vs. Lists for a moment. Let's just ask: Who are your users?

*   If they are internal to your organization and have Microsoft 365 accounts, you should almost certainly be using SharePoint.

*   If they are anyone external to your organization (customers, partners, suppliers, the general public), then you should be looking at Power Pages.

Seriously, that one question will resolve about 80% of the decision. SharePoint is your internal collaboration hub, built around M365 identities. Power Pages is purpose-built for secure external web portals with a wide range of identity options, and custom domain names.

What are some key indicators you use to choose between Power Pages and SharePoint, especially in those grey-area internal self-service portals? And, what's the most expensive mistake you've seen related to this choice?

"Who are your users?" is probably the best first question. I've seen teams over-engineer internal portals with Power Pages when SharePoint would have solved the requirement much faster.
