Power Apps vs. SQL Server vs. Staying in Access: How to Decide

Every week someone asks us the same question: “Should we get off Access?” The honest answer is that it depends on what’s actually going wrong. Many businesses don’t need to leave Access at all. Others need to move their data and keep their screens. Some need to start over on a modern platform.

This guide walks through the three realistic paths, what each one fixes, and what each one costs you. It’s based on more than 21 years of building, rescuing and migrating Access databases.

Option 1: Stay in Access (and make it solid)

Access is still part of Microsoft 365 business plans and still gets updates. For a small team in one office, a well-built Access database is often the cheapest, fastest tool you’ll ever own.

Staying makes sense when:

• Fewer than 10–15 people use it, and they’re on the same network.
• The data file is well under the 2 GB limit for an Access database.
• Nobody needs it on a phone, tablet or outside the office.
• The real problem is bugs, slowness or corruption, not the platform itself.

If that sounds like you, the right move is usually a cleanup: split the database into a front end and back end, fix the VBA that’s throwing errors, compact and back up on a schedule, and document how it works. That’s often a few days of work, not a few months.

The catch: Access was designed for a shared network drive. If your team is remote, or someone has put the file in OneDrive or SharePoint, you will keep fighting slowness and corruption no matter how good the database is.

Option 2: Move the data to SQL Server, keep the Access screens

This is the most underrated option. Your tables move to SQL Server (or Azure SQL), and your existing Access forms, reports and VBA keep working as the front end. Users mostly see the same screens they already know.

This path makes sense when:

• The database is getting close to 2 GB, or slows down as more people use it at once.
• You need real backups, security and audit trails on the data.
• Your forms and reports work well, and retraining everyone would be expensive.
• You want other tools (Power BI, Excel, a website) to read the same data.

SQL Server Express is free for databases up to 10 GB, which covers most small and midsize businesses. Larger or cloud-hosted setups use paid SQL Server or Azure SQL.

The catch: your users still need Access installed on a Windows PC. This fixes the data layer, not the “we need it on a phone” problem. Some queries also need tuning so they run on the server instead of pulling whole tables across the network.

Option 3: Rebuild in Power Apps (Power Platform)

Power Apps replaces the Access screens with web and mobile apps that run in a browser, on phones and inside Microsoft Teams. The data usually moves to Dataverse or SharePoint, and Power Automate takes over the emails, approvals and scheduled jobs your VBA used to handle.

This path makes sense when:

• People need the app in the field, on a phone or outside your network.
• You already run on Microsoft 365 and want sign-in, permissions and sharing handled by it.
• The process involves approvals, notifications or handoffs between people.
• Your Access database has become one person’s project that nobody else understands.

The catch: this is a rebuild, not a conversion. No tool turns Access forms and VBA into Power Apps automatically, so expect a real project. Licensing also matters. Apps built on SharePoint with standard connectors are covered by most Microsoft 365 business plans. Apps that use Dataverse or SQL Server need Power Apps Premium, which Microsoft is raising from $20 to $22 per user per month on January 1, 2027.

Side-by-side

	Stay in Access	Access + SQL Server	Power Apps
Best for	Small teams in one office	Growing data, same screens	Remote, mobile, multi-team use
Works on phones	No	No	Yes
User retraining	None	Minimal	Moderate
Typical project size	Days	Weeks	Weeks to months
Ongoing license cost	Included in M365	Free (Express) to moderate	Included (SharePoint) or Premium per user
Biggest risk	Remote access and corruption	Slow queries if not tuned	Underestimating the rebuild

Five questions that usually decide it

1. Where are your users? All in one office points to Access. Remote or in the field points to Power Apps.
2. How many people use it at the same time? Past about 15, the back end needs to be SQL Server or Dataverse.
3. How big is the data file, and how fast is it growing? Close to 2 GB means the data has to move.
4. How much logic is in VBA? Lots of VBA makes SQL Server the cheaper first step. You can still go to Power Apps later.
5. Who maintains it if your Access person leaves? If the answer is “nobody,” document it before you do anything else.

You don’t have to pick just one

Many of our projects are staged. We stabilize the Access database first so the business stops losing time. Then we move the data to SQL Server or Dataverse. Then we rebuild the pieces people need on the go in Power Apps, while the office keeps using what works. Each step pays for itself before the next one starts.

Not sure which path fits?

We’ll look at your database, how your team uses it, and where it hurts, then tell you which option makes sense, including “leave it alone” if that’s the right answer. Book a free diagnostic.

Brief #1: Access corruption errors

• Working title: “Unrecognized Database Format” and Other Access Corruption Errors: What to Do First
• Target keyword: unrecognized database format access (secondary: access database corrupted, access database keeps corrupting)
• Reader: someone whose database just stopped opening, often searching from a phone in a panic. Their main question is “Did I lose my data?”
• Goal: calm them down, stop them from making it worse, and get the hard cases to book a call.
• Links: Access Database Repair, Access Maintenance & Support, post #5

Outline

1. Stop before you click anything else. Copy the .accdb/.mdb file (and any .laccdb lock file) somewhere safe before trying repairs. Don’t keep reopening it.
2. What the common errors mean. “Unrecognized database format,” “The database is in an inconsistent state,” “Record(s) can’t be read; no read permission on MSysObjects,” and #Deleted showing in rows. One short paragraph each.
3. Safe first fixes, in order. Make sure everyone is out of the file and the lock file is gone. Run Compact & Repair on the copy. Import all objects into a new blank database.
4. Why it keeps happening. Not split into front end and back end, files in OneDrive/SharePoint/Dropbox sync folders, unreliable Wi-Fi or VPN, people killing Access mid-write, no compacting. Link forward to Brief #2.
5. When to call someone. Compact & Repair fails, tables come back with missing records, or it corrupts again within a few weeks.
6. Prevention checklist. Split the database, put the back end on a real network share or SQL Server, schedule backups, compact regularly.

Angle that sets it apart: most posts on this topic are just a list of fixes. Lead with “make a copy first” and end with “why it keeps happening” so readers see the bigger problem we solve.

Writer note: keep steps version-neutral (Access 2016 / 2019 / 2021 / Microsoft 365) and add a screenshot of Compact & Repair.

Brief #2: Access slow on OneDrive, SharePoint or the cloud

• Working title: Why Your Access Database Got Slow (or Started Corrupting) After Moving to OneDrive or SharePoint
• Target keyword: access database onedrive (secondary: access database sharepoint slow, access database remote users, access over VPN slow)
• Reader: a business that went remote or “moved everything to the cloud” and now has an Access database that crawls, locks up or corrupts.
• Goal: explain why it happens in plain English, give the stopgap, and show the real fix is one of our three paths.
• Links: Access to SQL Server Migration, Access to Power Platform Migration, post #5, Brief #1

Outline

1. The short answer. Access reads and writes pieces of the file constantly. Sync tools like OneDrive copy whole files. When several people do that at once, you get conflicts, slowness and corruption.
2. Signs you’re hitting this. “File in use” errors, conflicting-copy files appearing, edits that vanish, forms that take seconds to open.
3. What doesn’t work. Keeping the whole database in a synced folder, mapping a OneDrive or SharePoint library as a drive, running a split back end over a slow VPN.
4. Stopgaps that do work. Remote Desktop or a terminal server so Access runs next to the data, or an Azure Virtual Desktop setup. Be honest that these add cost and still leave you on Access.
5. Permanent fixes. Back end to SQL Server or Azure SQL (users keep the Access screens), or rebuild in Power Apps for browser and mobile access. Link to post #5 for choosing.
6. Quick self-check. Where’s the file? Is it split? How do remote users connect? Three answers that tell you which fix you need.

Angle that sets it apart: most search results just say “don’t do this.” We explain why, offer a stopgap, and give a migration path, so it serves both the panicked reader and the planner.

Writer note: a simple diagram of “one shared file vs. a server” would help a lot. Avoid Microsoft-bashing in the tone. Access wasn’t built for this, and that’s okay.

Brief #6: What an Access to Power Platform migration really costs

• Working title: What an Access to Power Apps Migration Really Costs (Including the 2027 License Increase)
• Target keyword: access to power apps migration cost (secondary: power apps licensing cost, power apps premium price 2027)
• Reader: a decision-maker who likes the idea of Power Apps but needs a number for the budget or the boss.
• Goal: be the honest pricing page nobody else writes. Readers who trust the ranges book the diagnostic to get their real number.
• Links: Access to Power Platform Migration, Power Apps Development, post #5
• Timing: publish before January 1, 2027. The price change is a news hook that expires.

Outline

1. The two costs: building it and running it. Project cost is one-time. Licensing is every month, per user, forever. Most people only ask about the first.
2. What drives project cost. Number of tables, forms and reports, amount of VBA logic, integrations (QuickBooks, email, Excel exports), data cleanup, and training. Give ranges by size (small / medium / complex) using your own past projects. Don’t quote fixed prices.
3. Licensing in plain English.
   • SharePoint-based canvas apps with standard connectors are covered by most Microsoft 365 business plans at no extra license cost.
   • Dataverse, SQL Server and other premium connectors need Power Apps Premium: $20 per user per month today, rising to $22 on January 1, 2027 (Microsoft).
   • The old $5 per-app plan is no longer sold to most new customers; pay-as-you-go runs about $10 per active user per app per month.
   • Premium includes a pooled Dataverse storage allowance per user; extra storage costs more. Verify current figures on Microsoft’s pricing page before publishing.
4. A worked example. 15 users, one app, Dataverse: licenses at $22 × 15 × 12 ≈ $3,960 per year from 2027. Compare with the SharePoint route ($0 extra) and the Access + SQL Server Express route ($0 extra). This is the section people will screenshot and forward.
5. Hidden costs. Premium connectors you didn’t plan on, Dataverse storage growth, Power Automate licenses for unattended flows, and staff time during the switchover.
6. How to keep it down. Design for SharePoint where it’s good enough, license only the users who need premium features, migrate in stages.
7. CTA. “Get your actual number” leading to the free diagnostic
