The question is usually framed as technical: where is my data stored? It is really a management question: who carries the responsibility for running, securing, and updating the system — you or the vendor?
Framed that way, the decision becomes far clearer.
Eight Points of Comparison
| Aspect | Cloud | On-premise |
|---|---|---|
| Starting cost | Low — a recurring subscription | High — licence plus server |
| Updates | Automatic and included | Manual and usually chargeable |
| Backups | The vendor's responsibility | Entirely yours |
| Access | Any place, any device | The machine or local network |
| Internet dependency | Required | Not required |
| Deep customisation | Limited to what the vendor allows | Broader |
| Security | Data-centre grade | Your own setup's grade |
| Continuity | Tied to the vendor surviving | Tied to you maintaining the server |
The Common Illusion: "My Data Is Safer Here"
This belief is widespread and understandable, but it holds only if you do what a data centre does: daily backups in a separate location, periodic restore testing, regular security patching, and protection against power loss, fire, and theft.
Most small businesses do none of that. The server sits in the manager's office and the backup drive sits beside it — meaning one incident takes both.
The honest rule: your data is safer where it is professionally managed, not where it is physically near you.
The Opposite Illusion: "Cloud Means My Data Isn't Mine"
Your data is yours either way; the difference is how easily you can extract it. So the right question isn't "where is my data?" but: can I export all of it whenever I want?
A cloud vendor who gives you full export at any time makes the location question secondary. A vendor who doesn't — cloud or on-premise — is the actual problem.
The Three-Year Cost Calculation
For the full detail see the accounting software cost guide.
Don't compare a subscription against a licence price. Total each option:
- Cloud: subscription × 36 months + setup + migration + training.
- On-premise: licence + server + its operating system + annual support (typically 15%–25% of the licence per year) + backups + upgrades + the time of whoever administers it.
The last item on the second list is the most overlooked and usually the largest: somebody's hours — yours or an employee's — spent managing a server rather than running your business.
When On-Premise Genuinely Wins
Two cases only. Outside them, cloud suits most small and mid-sized businesses:
- A regulatory or contractual obligation requiring data to remain on your servers or inside the country.
- Working at a site with no stable internet — a remote location or an isolated industrial facility, where an outage genuinely halts work.
Even in the second case, many modern systems run locally and sync when the connection returns — so verify before ruling cloud out for that reason.
Five Questions for a Cloud Vendor Before Subscribing
- Where is the data hosted geographically? It matters if you have a data-residency obligation.
- How often are backups taken? And when was a restore last tested?
- Can I export all my data at any time? And in what format?
- What happens to my data if I stop subscribing? A grace period to export, or immediate lockout?
- What uptime is guaranteed? And what compensation applies to an extended outage?
The fourth is the most important and the least asked — and its answer reveals how the vendor will treat you the day you decide to leave.
Frequently Asked Questions
What is the difference between cloud and on-premise accounting software?
Cloud runs in a browser and is hosted by the vendor, who handles updates, backups, and security in exchange for a recurring subscription. On-premise runs on your machine or server, so you carry those responsibilities in exchange for a one-time licence plus annual support.
Which is more secure?
Cloud is more secure for most small businesses, because data centres provide off-site backups, security patching, and physical protection that an office room does not. Proximity to your data isn't security.
Is cloud more expensive long term?
Not necessarily. Compare over three years, and add to on-premise the server, annual support, upgrades, backups, and the time of whoever administers it. In most small and mid-sized businesses the difference disappears or reverses in cloud's favour.
What happens if the internet goes down?
Work stops on purely cloud systems. But many modern systems — especially at the point of sale — run locally and sync when the connection returns. Ask about this specifically before subscribing.
Can I migrate from on-premise to cloud?
Usually yes, and the real obstacle isn't technical but about data: can your old system export everything in an importable format? Start with that question before anything else.
When should I choose on-premise?
In two cases: a regulatory or contractual obligation requiring data to stay on your servers, or work at a site with no stable internet where the system offers no offline mode.
Conclusion
The question isn't "where is my data" but "who carries responsibility for it". If you have a technical team and a regulatory reason, on-premise is a legitimate choice. If you don't, you are buying a responsibility rather than a system.
Ask yourself one question: when did you last test restoring a backup? The answer tells you which option actually suits you.
