Power Apps vs custom web app

Power Apps can be a smart choice when a team already uses Microsoft 365 and needs an internal workflow quickly. A custom web app is stronger when the experience, customer access, unusual data model, public portal or product direction needs more control. The right answer depends on users, data, licences, security and support.

§01

The short answer

Use the comparison to choose the smallest useful next step, not the fanciest tool.

Power Apps

Microsoft-first internal workflows

Useful for forms, inspections, approvals and job tracking when Microsoft 365, Dataverse or SharePoint are already central.

Custom web app

More control

Better for custom UX, customer-facing apps, product-grade interfaces, unusual permissions or integrations beyond the Microsoft stack.

Power Pages

External Microsoft portal

Useful when customers, suppliers or members need portal access tied to Dataverse records.

Decision

Licence and data first

The comparison should start with users, records, permissions, reporting, licence cost and who will support it after launch.

How Doohickey helps

We start with the business job, check the support risk, then scope the leanest path that can be owned after launch.

Scope

Write the boundary first

Before a build starts, we define the users, data, workflow, support path and what is deliberately out of scope.

Proof

Show the working

Useful proof might be a prototype, redacted screenshot, report, workflow map, form test, log or handover note.

Support

Plan the aftercare

Phone and email support, CMS updates, backups, monitoring and response targets are discussed before launch.

Growth

Make the offer clear

Service pages, FAQs, glossary links and internal links help buyers understand the offer and choose the right next step.

§04

Power Apps vs custom web app questions

Plain answers for Australian small and medium businesses comparing digital providers, platforms, support and AI options.

Is Power Apps cheaper than a custom app?

Sometimes, especially for Microsoft-first internal workflows. Licence cost, Dataverse design and future support still need to be checked.

When is a custom web app better?

When the business needs a tailored customer experience, unusual permissions, product ownership, complex integrations or public-facing app behaviour.

Can Doohickey build both?

Yes. We can scope Power Apps, Power Pages, Dataverse and custom web apps, then recommend the lighter path when it suits.
