Modern businesses don’t fail because they lack ambition… they struggle because everyday processes get in the way. 

Too many spreadsheets. 

Too many manual handovers. 

Too many “quick fixes” that, in the long-term, become big problems.

That’s where Microsoft Power Apps comes in.

Power Apps gives businesses the opportunity to build custom apps that actually fit how they operate, without needing a full development team or months of build time. From automating repetitive admin to replacing clunky legacy tools, it can help teams move significantly faster, stay organised, and get more value from the Microsoft tools they already use.

Whether you’re simplifying approvals, streamlining data entry, or giving teams mobile-friendly tools that work anywhere, Power Apps makes it possible.

In this guide, we’ll explain what Microsoft Power Apps is, how it works, where it delivers the most value, and when it’s the right (or wrong) choice for your business.

We’ll cover:

• What Microsoft Power Apps is (and what it isn’t)
• How Power Apps works alongside Microsoft 365
• The key features that make it so powerful
• The types of apps businesses are building today
• Common real-world use cases
• When Power Apps is the right choice, and when it’s not
• How Lyon Tech helps businesses design, build, and manage Power Apps properly

Let’s start at the beginning.

What Is Microsoft Power Apps?

Microsoft Power Apps is a low-code app development platform that lets businesses create custom applications without starting from scratch or relying entirely on developers. Instead of long development cycles and complex code, apps are built using a visual, drag-and-drop interface that makes development faster and more accessible.

Power Apps exists to solve a common problem: off-the-shelf software rarely fits perfectly. Every organisation has its own workflows, approvals, and data requirements. Power Apps fills that gap by letting you build tools that match how your teams already work.

As part of the Microsoft Power Platform, Power Apps integrates with Microsoft 365, SharePoint, Teams, Excel, and Dynamics 365. This means you can turn existing data into practical, easy-to-use apps rather than juggling spreadsheets and disconnected systems.

While developers can extend apps with custom logic and integrations, non-technical users can also build and maintain everyday apps. The result is faster innovation, less strain on IT teams, and tools people actually want to use.

How Microsoft Power Apps Works

Power Apps removes much of the complexity traditionally associated with building business applications. Instead of writing large amounts of code, users design apps visually by combining screens, data sources, and logic.

Apps are created by connecting Power Apps to existing data, such as Excel files, SharePoint lists, Dataverse, SQL databases, or Dynamics 365. Once connected, that data can be turned into interactive forms, dashboards, and workflows accessible through a browser or mobile device.

Power Apps works especially well within the wider Microsoft Power Platform, alongside:

• Power Automate, for approvals, notifications, and automated workflows
• Power BI, for reporting and insights inside apps
• Dataverse, for secure, scalable data storage

Apps don’t exist in isolation: they become part of a connected system that reduces manual effort and keeps information flowing automatically.

For more advanced needs, developers can extend functionality using APIs, connectors, or custom code. This hybrid approach allows businesses to move quickly without sacrificing control or governance.

Key Features of Microsoft Power Apps

Microsoft Power Apps isn’t just about speed: it’s about building apps that are usable, secure, and scalable.

The visual app builder allows teams to prototype and iterate quickly, refining apps based on real feedback rather than assumptions. This encourages adoption and reduces wasted effort.

Power Apps also offers strong data integration, connecting to hundreds of Microsoft and third-party services. Apps work with live data, helping teams stay aligned and make better decisions.

Built-in device responsiveness means apps work across desktop and mobile without additional development, which makes it ideal for remote and hybrid teams.

Security is handled through Microsoft’s ecosystem, with enterprise-grade identity, access controls, and compliance features built in. IT teams retain visibility and control while business users innovate safely.

Finally, Power Apps is designed to grow with your organisation. You can start small and expand over time, enhancing apps without rebuilding them from scratch.

Types of Apps You Can Build With Power Apps

So, what can you actually build? 

Many organisations begin with task and workflow apps, replacing shared spreadsheets or email chains with a single source of truth for responsibilities and approvals.

Employee-facing apps are also common, helping streamline onboarding, HR requests, and internal processes by bringing forms and information into one place.

Finance teams often use Power Apps for expense tracking and approvals, reducing delays and improving visibility over spending.

For operations teams, inventory and asset management apps help track stock, equipment, and usage in real time.

Power Apps is also well-suited to feedback and data collection, whether that’s customer surveys, internal reporting, or compliance checks.

Common Use Cases for Microsoft Power Apps in Business

Power Apps is most effective when it removes everyday friction.

Many businesses use it to digitise manual processes, replacing paper, emails, or spreadsheets with guided, consistent workflows that reduce errors and improve visibility. Others use Power Apps to centralise data, pulling information from multiple systems into a single interface so teams can work from accurate, real-time information.

Power Apps also supports lightweight collaboration, enabling departments to build small, purpose-built apps that fit naturally into tools like Microsoft Teams.

Automation plays a major role, too. When combined with Power Automate, Power Apps can trigger approvals, alerts, and updates automatically, saving time and reducing missed steps.

When to Use Microsoft Power Apps (and When Not To)

Power Apps is a great fit when you need to streamline internal processes, integrate existing systems, or move quickly without heavy development overhead - especially if you already use Microsoft 365.

It’s ideal for testing ideas, rolling out solutions fast, and evolving them over time.

However, Power Apps isn’t suited to every scenario. Highly complex, customer-facing applications with demanding performance or bespoke user experience requirements may require traditional development. Organisations with very specialised compliance needs should also assess suitability carefully.
