For years, dental practice management software ran on a server in the back room. Today, more practices are moving to cloud-based systems that run in a web browser and store data in a provider's data centre. The decision affects almost everything: how your team works, how secure your data is, how easily you can add new tools like AI receptionists, and what happens when the internet drops out.
This guide compares cloud and on-premise dental practice software for Australian practices, so you can decide which suits yours.
Key takeaways
- Cloud software runs over the internet, with the vendor managing servers, updates and backups. On-premise software runs on your own server, which you or your IT provider manage.
- Cloud makes remote access, multi-site operations and integrations easier, and shifts much of the maintenance burden to the vendor.
- On-premise gives you direct control and works during internet outages, but you're responsible for security, backups and updates.
- Either way, you remain responsible for patient privacy. Check where data is stored and how it's protected.
- Migration is a significant project. Plan it carefully and run old and new systems side by side where possible.
What's the difference?
On-premise
The software is installed on a server at your practice, with workstations connecting over the local network. You buy or license the software, maintain the server, and manage backups, updates and security, usually with an IT provider.
Cloud
The software is accessed through a web browser or a lightweight app, and data is stored in the vendor's cloud infrastructure. You pay a subscription, and the vendor handles servers, updates, backups and much of the security.
Hybrid
Some systems combine both, for example an on-premise system with cloud backups, online booking or a cloud-hosted server you access remotely.
Advantages of cloud software
- Access from anywhere: practice owners and managers can check the diary or reports from home, and multi-site groups can share one system.
- Less IT to manage: no server to buy, replace or patch.
- Automatic updates: new features and security fixes arrive without upgrade projects.
- Easier integrations: cloud systems often have modern APIs, which make it easier to connect online booking, reminders, AI receptionists and reporting. See connecting an AI receptionist to your practice software.
- Predictable costs: a monthly subscription instead of large upfront purchases.
- Built-in resilience: reputable providers run backups and redundant infrastructure.
Advantages of on-premise software
- Works without internet: the diary and records stay available if your connection drops.
- Direct control over your data and server.
- Long track record: many established systems are mature and familiar to staff.
- Performance: large files, such as imaging, can load quickly over the local network.
Disadvantages to weigh
Cloud
- Internet dependence: a reliable connection, ideally with a backup such as a 4G or 5G failover, becomes essential.
- Ongoing subscription costs that continue for as long as you use the system.
- Less control over the timing of updates and changes.
- Data location: check where data is stored, and whether any of it leaves Australia.
On-premise
- Server costs and replacement cycles.
- Security and backups are your responsibility. Practices are attractive targets for ransomware, and a single server without tested off-site backups is a serious risk.
- Harder remote access and multi-site sharing.
- Integrations can be harder, so adding new tools may take longer or cost more.
Security and privacy
Whichever you choose, your practice is responsible for protecting patient information under the Privacy Act and the Australian Privacy Principles. Check:
- Multi-factor authentication for all logins, especially remote access
- Encryption of data in transit and at rest
- Backups: how often, where they're stored, and whether restores are tested
- Access controls: each staff member has their own login with the right permissions
- Audit logs of who accessed or changed records
- Data location and subprocessors. See patient data and AI vendors
- Breach response: what the vendor will do, and how quickly they'll tell you, if something goes wrong
Questions to ask a cloud vendor
- Where is our data stored and processed?
- What uptime do you commit to, and what happens during an outage?
- How are backups handled, and can we get a full export of our data?
- What integrations and APIs are available?
- How does imaging work, and how fast is it?
- What does migration from our current system involve, and what data comes across?
- What does it cost, including per-user, per-provider and add-on fees?
Planning a migration
- Clean your data before moving: duplicate patients, old recalls and inactive providers.
- Confirm what migrates: appointments, patient records, clinical notes, imaging, treatment plans, balances and recalls.
- Test the migration with a copy of your data.
- Train the team before go-live.
- Choose a quiet go-live date and have vendor support on hand.
- Keep read access to the old system for a period after the switch.
Frequently asked questions
Is cloud software less secure than on-premise?
Not necessarily. A reputable cloud provider often has stronger security than a single practice server. But security depends on the provider, your settings and how your team uses it.
What happens if the internet goes down?
With cloud software, you may lose access until it's restored, unless the system has an offline mode. A backup internet connection reduces the risk.
Will cloud software work with AI receptionists?
Cloud systems often have APIs that make integration easier, but it varies. Ask both vendors what's actually supported.
