Microsoft Power Apps: Build Custom Business Applications Without Writing Code

Microsoft Power Apps is used to build custom business applications without writing code. Common use cases include warehouse and field inspection apps that collect data on mobile devices, approval routing apps that replace email chains, customer or partner portals that expose data from back-end systems, inventory management tools that connect to ERP data, and quality check forms that trigger automated workflows. Power Apps connects natively to Dynamics 365, Business Central, Microsoft 365, SharePoint, and hundreds of third-party systems through prebuilt connectors.

Power Apps connects to Dynamics 365 Business Central through Microsoft Dataverse, the underlying data platform that Business Central runs on, and through prebuilt connectors available in Power Apps. A common use case is a warehouse mobile app that lets staff scan items and update inventory records in Business Central from a tablet or phone without logging into the full Business Central interface. Western Computer builds Power Apps connected to Business Central for manufacturers and distributors who need custom tools for field teams, warehouse operations, or approval workflows.

Power Apps is appropriate for apps that need to be built quickly, maintained by business users, and connected to existing data sources without deep technical complexity. Custom development is appropriate when you need highly specialized logic, external-facing applications with complex security requirements, or functionality that Power Apps connectors cannot reach. Western Computer helps manufacturers and distributors determine which requirements can be addressed with Power Apps and which are better suited for custom development. In some cases, the best solution combines both, using a Power App for the user interface and a custom API to handle specialized business logic or system integrations.

Yes, for straightforward use cases. Power Apps canvas apps use a drag-and-drop interface similar to PowerPoint, and prebuilt templates get you 70 to 80 percent of the way for common business processes like expense reporting, approval routing, or basic inventory lookups. More complex apps that need custom business logic, advanced data relationships, or integration with systems outside Microsoft's connector library benefit from a professional developer. Western Computer provides both self-service enablement training and full-service Power Apps development for when a team member's vision exceeds what they can build independently.

Power Apps is available in two licensing models. The per-app plan allows each user to run one or two apps for $5 per user per month. The per-user plan allows unlimited app access for $20 per user per month. Many Microsoft 365 and Dynamics 365 licenses already include limited Power Apps capabilities. Check your existing licensing before purchasing standalone Power Apps licenses, as you may already have access to canvas apps and standard connectors.

Power Apps supports three app types. Canvas apps use a drag-and-drop interface and connect to more than 200 data sources, making them ideal for mobile field applications, approval workflows, and custom data entry forms. Model-driven apps are built around structured business data in Microsoft Dataverse and work well for case management, project tracking, and CRM-like tools. Power Pages lets you build secure external-facing websites and portals for customers, partners, or employees to interact with your business data through a browser.

Western Computer has been implementing Microsoft solutions for manufacturers and distributors since 1987. We are a Microsoft Inner Circle member and a G2 Leader in Microsoft Consulting Services for 9 consecutive quarters. We build Power Apps as standalone solutions and as extensions of Dynamics 365 and Business Central implementations, connecting custom applications directly to ERP data from day one.
