Short answer: keep Access when users work on Windows PCs in one office or via remote desktop, need rich forms, printable reports and VBA automation, and you want low running costs. Choose Power Apps when users need phones, tablets or browsers from anywhere, you are standardising on Microsoft 365 and Dataverse, and per-user licensing fits the budget. The common middle path is a SQL back end with Access for office staff and a Power App for mobile users. Our migrate and upgrade service recommends a path in writing.
"Should we move our Access database to Power Apps?" is one of the most frequent questions we are asked, often after someone has seen a Microsoft demo or a new IT policy discourages desktop databases. Power Apps is a strong platform. It is also a different kind of tool with different costs, and swapping one for the other without a reason creates expense without benefit.
Side-by-Side
| Aspect | Microsoft Access | Power Apps |
|---|---|---|
| Where it runs | Windows desktop (or remote desktop) | Browser, iOS, Android, Teams |
| Data | Access tables, SQL Server, other ODBC sources | Dataverse, SQL, SharePoint, hundreds of connectors |
| Build experience | Forms, reports, queries, VBA | Canvas or model-driven apps, Power Fx formulas |
| Printable reports | Excellent, built in | Limited; usually Power BI or generated documents |
| Automation | VBA, macros | Power Automate flows |
| Offline use | Yes (desktop) | Possible with design effort |
| Licensing | Included in many Microsoft 365 plans; free Runtime | Per-user or per-app for premium features and Dataverse |
| Governance | File-based; IT visibility varies | Centrally managed environments and policies |
Cost: The Factor People Underestimate
An Access application used by 25 staff often has almost no ongoing software cost beyond existing Microsoft 365 licences, plus hosting for a SQL back end if used. A Power App with premium connectors or Dataverse needs licences for every user, every month, and Dataverse storage beyond included capacity is also charged. Over five years, the licence total can exceed the build cost many times over. Microsoft's pricing changes, so model it with current figures before deciding.
| Cost element | Access | Power Apps |
|---|---|---|
| Build | Moderate | Moderate to high (redesign) |
| Per-user licence | Usually none extra | Recurring for premium/Dataverse apps |
| Data platform | Access file or SQL Server (Express is free) | Dataverse capacity or SQL / Azure SQL |
| Hosting for remote users | Remote desktop or SQL hosting | Included in the cloud service |
Where Power Apps Clearly Wins
Field staff need to capture data on phones: inspections, deliveries, site photos, signatures.
Users are spread across sites, home and partners without a common network.
The organisation already runs on Dataverse, Dynamics 365 or SharePoint, and wants one platform.
IT requires central governance, data loss prevention policies and no desktop databases.
Simple forms and approvals connected to Microsoft 365 (Teams, Outlook, SharePoint).
Where Access Clearly Wins
Dense, keyboard-heavy data entry by office staff all day.
Complex printable reports: invoices, statements, certificates, grouped management reports.
Rich business logic already written in VBA that works.
Small teams where per-user licences are hard to justify.
Rapid development of internal tools by people who know Access.
The Hybrid Path Most Teams Take
1. Move the tables to SQL Server or Azure SQL
Access forms keep working through linked tables; data becomes reachable from anywhere.
2. Keep Access for the office
No retraining, no lost reports.
3. Add a focused Power App
For the specific mobile or remote task, on the same SQL data.
4. Move reporting to Power BI if needed
For dashboards shared beyond the Access users.
This avoids a big-bang rebuild and lets you prove value step by step. The back-end move is covered in AI-assisted Access to SQL Server migration; platform choice for the data in Access vs Dataverse vs SQL Server.
If You Do Rebuild in Power Apps
Document the Access database first: every form, report and process, and what is actually used.
Redesign screens for the platform; copying Access forms one-to-one produces clumsy apps.
Plan for delegation limits: Power Apps processes some queries locally and may only see the first rows of large tables unless the data source supports the filter.
Decide where reports will live (Power BI, Word templates via Power Automate).
Budget for licences from the start, including Dataverse storage.
Documentation is the step that saves the most money; see documenting a legacy Access database with AI. For browser access without Power Apps licensing, a custom web application is another option; see MS Access to web application.
