Power Apps, SharePoint or Dataverse?

How to think about the right foundation for an internal business system.

Start with the data model

Power Apps is the user experience layer, not the database. The first architectural question is usually where the data should live. SharePoint lists can be a strong fit for simpler collaborative scenarios, while Dataverse is designed for richer relationships, security models and business applications.

When SharePoint can be enough

A SharePoint list can work well when the data structure is straightforward, relationships are limited, permissions are relatively simple and the organization already uses SharePoint heavily. It can also be a good foundation for lightweight request tracking.

When Dataverse becomes valuable

Dataverse is often a better fit when the system has multiple related tables, more complex role-based access, model-driven apps, Dynamics integration or a need for a more formal application platform.

Where Power Apps fits

Power Apps can provide a cleaner interface over either source. A canvas app gives you more control over the screen experience. A model-driven app is built around Dataverse and can be a strong choice for structured, record-driven business processes.

Choose for maintainability, not just launch speed

The fastest first build is not always the cheapest long-term architecture. Consider expected data volume, relationships, security, reporting, licensing and future integrations before choosing the foundation.

What to do next

Choose one process that is repetitive, visible and reasonably stable. Map what happens today, identify the required data and exceptions, and then evaluate the smallest Microsoft solution that can improve it.
