Introduction
Building custom business applications used to mean one thing: months of waiting, a small army of developers, and significant budgets. Not anymore.
Here's the pattern we see frequently. A leader wants a simple internal tool (a request form, an approval flow, a field checklist). The business need is urgent. But the “traditional build” conversation turns into scoping meetings, backlog debates, and calendar math. Meanwhile, competitors are shipping operational apps in weeks.
At Aureus Intelligence AI, we focus on the practical outcomes with structured delivery leveraging Microsoft power platform services.
Traditional development means requirements gathering, design, coding, testing, and deployment. For complex applications, that's 6 to 18 months and £50,000 to over half a million. None of that makes it wrong, it just makes it expensive and slow. Sometimes that's what a project needs. But often, it isn't.
What is Microsoft Power Apps?
Microsoft Power Apps is a low-code application platform within the Microsoft Power Platform ecosystem. It enables organisations to build business applications faster using visual design tools, reusable components, and built-in connectors all the while still allowing deeper customisation when needed. Think of it as the middle ground between a spreadsheet and a full custom application.
Three Types of Power Apps: Choosing the Right Approach
At Aureus Intelligence AI, we work with clients to determine which type of Power App best fits their specific business requirements. Each type serves distinct purposes and use cases:
1. Canvas Apps: Maximum Flexibility for Custom Workflows
Canvas Apps shine when you need flexibility and speed. Whether you're building a maintenance tracking app for field technicians or a customer feedback tool for retail teams, Canvas Apps deliver custom functionality without custom development timelines.
Best suited for:
- Field operations and mobile-first applications (inspections, site visits, service delivery)
- Custom data capture forms with specific branding requirements
- Applications where user experience is paramount
- Rapid prototypes and proof-of-concept builds
- Connecting to multiple data sources in a single interface
2. Model-driven Apps: Enterprise-Grade Data Management
Model-driven Apps are the right choice when your priority is managing complex business data rather than designing custom interfaces. Think CRM extensions, case management systems, project tracking tools, and department-wide operational platforms.
Best suited for:
- Complex data relationships and business processes
- Enterprise applications requiring robust security and compliance
- Applications with significant data volumes and reporting needs
- Teams that need consistent, standardised interfaces
- Projects where data integrity and governance are critical
3. Power Apps Portals: External-Facing Applications
Power Apps Portals (now Power Pages) bridge the gap between internal business systems and external users, all while maintaining enterprise-grade security and compliance. If you need to give controlled access to your Dataverse data without handing out Microsoft 365 licenses, Portals are the answer.
Best suited for:
- Customer self-service portals (account management, case submission, knowledge bases)
- Partner and vendor collaboration platforms
- Event registration and management
- Job application and recruitment portals
- Community engagement and feedback collection
Typical Business App Use Cases
Across all three types, Power Apps addresses common operational challenges:
- Forms and data capture (inspections, audits, checklists)
- Approvals and workflows (requests routed to the right people)
- Internal tools (operational tracking, handoffs, reporting)
- Field apps (mobile-first apps for frontline teams)
- Customer-facing portals (self-service, collaboration, information access)
Built-In Integration and Scalability
Microsoft Power Apps come with Dataverse, a secure, scalable data platform that handles storage, relationships, and business logic. It's where your app data lives, and it's built for enterprise-grade performance. Beyond Dataverse, Power Apps connects to over 1,000 pre-built connectors. Systems like SharePoint, SQL Server, Salesforce, SAP, ServiceNow, and hundreds more. If your data lives somewhere, chances are there's already a connector for it.
Aureus Intelligence AI supports this end-to-end through our Microsoft Power Platform services.
We help clients assess requirements, select the appropriate app type, design scalable solutions, and implement governance frameworks—helping you realise just how much you can do with infrastructure you've already paid for.
Whether you need a Canvas App for rapid deployment, a Model-driven App for complex data management, or a Portal for external engagement, we'll ensure you choose the right approach and execute it properly.
The Differences That Actually Matter to Enterprises
When comparing Microsoft Power Apps vs. traditional app development, five factors consistently shape the decision:
1. Development Speed
Power Apps takes you from concept to working application in days or weeks. Traditional development measures timelines in months. If you needed this yesterday, that gap isn't subtle.
2. Cost
Two components matter here: licensing and development. Power Apps operates on a subscription model which equate to predictable monthly costs, and lower upfront investment. Development costs are also reduced because you're not paying for months of custom coding. Traditional development demands significant capital expenditure before you see any return, plus ongoing maintenance budgets.
3. Flexibility
Need to change something in a Power App? Updates can happen the same day. Traditional applications mean formal change requests, development cycles, and regression testing. A small tweak can take weeks. Power Apps wins on iteration speed; traditional development wins on depth of customisation.
4. Maintenance
Microsoft handles platform updates, security patches, and infrastructure for Power Apps. Custom-built software? That's your responsibility and expense. For enterprises, this also means considering ALM (Application Lifecycle Management) and governance. Microsoft's CoE Starter Kit helps manage environments and enforce standards at scale.
5. Scalability
Both approaches can scale. Power Apps runs on Azure's enterprise infrastructure out of the box. Traditional development requires you to architect for scale yourself.
For enterprise teams, additional factors come into play: governance and security (Power Apps inherits Azure AD, role-based access, and DLP policies), integration with your current tech stack (1,000+ connectors, plus custom connectors for REST APIs), and whether your organisation needs a formal Centre of Excellence structure as adoption grows.
When Power Apps Makes Sense
Power Apps isn't the answer to everything. But it's often the answer to more than people expect. It tends to be the right fit when:
- You're digitising department-level workflows, not building enterprise-wide infrastructure
- You want to prototype quickly before committing to a larger investment
- Citizen development with IT governance and security controls
- Better visibility into operational data and performance
If you’re evaluating fit, microsoft power apps consultant can map requirements, assess data sources, and recommend the fastest path that won’t create long-term risk.
When Traditional Development is Worth It
Power Apps is powerful, but it's not limitless. Some projects genuinely need what only traditional development can offer:
- Complex, customer-facing products where user experience is the differentiator
- Applications with heavy computational requirements or real-time data processing
- Proprietary algorithms or IP-sensitive logic that needs to stay in-house
- Legacy system integrations where modern APIs simply don't exist
Why Working with Aureus Intelligence AI to help with Your Power Apps Journey?
We're not a Power Apps shop that pushes low-code on every project. And we're not a traditional dev house that dismisses anything without a six-figure budget. We help you figure out which approach makes sense, then deliver it.
- Honest assessments: we'll tell you if Power Apps isn't the right fit, even if it means a smaller engagement for us
- End-to-end capability: strategy, build, integration, training, and ongoing support, all under one roof
- Hybrid expertise: when projects need both low-code speed and custom development muscle, we blend both
- Enterprise-ready: we help clients implement proper ALM, governance frameworks, and CoE structures from day one
