It's a question I'm asked in almost every first meeting: why don't we do it in .NET, React, or whatever? It's a legitimate question. Before recommending Power Platform, the client has the right to understand why I'm choosing this tool and not another.
90% of business processes are variations of the same pattern
If you look at the internal processes of any mid-sized company, most are variations of the same thing: someone enters data, that data goes through one or several approvals, gets stored, generates notifications, feeds a report, and eventually gets exported to another system. Order management, purchase requests, quality control, employee onboarding, incident management — the pattern is the same.
Does it make sense to write custom code for each of these processes? If the answer is "we need an app that captures data, validates it, sends notifications, manages approvals, and shows it in a dashboard", Power Platform does it in weeks with a platform that Microsoft maintains, updates, and patches for you.
Delivery speed: weeks vs months
A process app that would take 3-4 months in custom development (requirements gathering, design, development, testing, deployment, training), in Power Apps with Dataverse you have it in weeks. With governance, with ALM, with separate development-test-production environments. It's not a prototype: it's production.
In real projects, I've seen how an application that would take months of work with a dedicated team in custom development can be in production in Power Apps in weeks — including integration with other systems and team training. The difference is that you don't have to write authentication, role management, data APIs, or deployment infrastructure. All that already exists on the platform.
Total cost of ownership: the number nobody calculates
A development project budget is usually calculated as development cost + margin. But the real cost of a custom application includes hosting, monitoring, framework updates, security patches, developer rotation (and the learning curve of the new one), and vendor dependency (whoever built it). Power Platform eliminates most of these costs: Microsoft handles the infrastructure, security, updates, and the application is maintainable by anyone with platform knowledge.
I've seen companies spending more on maintaining an old custom app than it would cost to rebuild it in Power Platform and pay for the licenses for years.
The internal team can evolve the solution
This is the argument with the most weight for me. With custom development, every change requires a developer. Want to add a field? Developer. Change a validation rule? Developer. A new report? Developer. With Power Platform, the business team can make these changes — with proper governance — without opening a ticket or waiting for a sprint.
In one of my projects with a multinational manufacturer, the internal team I helped recruit and train today creates solutions on their own. Not because they're developers, but because Power Platform is designed to let business people build solutions within a governed framework.
When custom development IS necessary
I'm not dogmatic. There are clear cases where Power Platform isn't the answer: applications needing millisecond latency, complex calculation algorithms or advanced machine learning, pixel-perfect UIs that don't fit standard controls, or SaaS products you're selling to third parties. If your case is one of these, I'll tell you in the first meeting — I'm not going to force a tool where it doesn't fit.
But if your challenge is digitizing internal processes, connecting departments, automating repetitive tasks, or giving visibility to your company's data, Power Platform is the most pragmatic answer that exists today in the Microsoft ecosystem. And I'm not saying it because it's what I sell — I'm saying it because after years implementing it in real companies, I've seen the difference.
