Licensing question regarding PowerApps for external users

HIChristian_ORBIS 

Please review the following for the guidance you need to best resolve your solution. 

Is it correct that also external users can get a Power App licence from our customer (he will purchase the licenses for them) as we can add them as a guest user in AD?

Not a full license. As stated on the pg. 42 of the Power Platform Licensing Guide, limited external user access is included with your internal user licenses.

You also have the option to license Power Pages to provide external access to your business processes or data.  Please review the go to Microsoft Power Apps and Power Automate Licensing Guide for details.

As far as adding them to your Azure directory, guests can view documents.  To add guests in the Azure Active Directory - Quickstart: Add a guest user and send an invitation - Microsoft Entra | Microsoft Learn and, External Identities in Azure Active Directory - Microsoft Entra | Microsoft Learn

There are new Power Apps Portals login capacity add-on and Portals page view capacity add-on for external users of Power Apps Portals - Power Platform licensing FAQs - Power Platform | Microsoft Learn

For these users we want to build an own small model driven app which contains only the necessary forms and tables to get the price info using the quote functionality. As they will not write any restricted tables we want to use a Power Apps license for them and give them an own small model driven Power App.

I'm not sure if you're asking for information on buidling model driven apps, but here's some information if needed:Share a canvas app with guest users (contains video) - Power Apps | Microsoft Learn and Overview of building a model-driven app with Power Apps - Power Apps | Microsoft Learn

Are there any limitations beside the restricted tables we have to be aware of using a power apps license?

hmmm...that's a general questions and unfortunately, I do not have an answer that will foresee limitations. The following links are resources that are available to you from Partner Center

Note: If you are a Reseller, please contact your Indirect Provider.  Otherwise, I suggest using the Power Apps community for the power apps portion of this scenario - Power Platform for partners - Microsoft Community Hub
