Limitations of Computerised Accounting

4. Limitations of Computerised Accounting System

1. Cost of hardware, software, and training — setting up a CAS requires an upfront investment that a very small business, comfortable with manual books, may find hard to justify.
2. Risk of data loss or corruption — without a proper, disciplined backup routine, a hardware failure, virus, or accidental deletion can wipe out accounting data that a physical ledger, by contrast, cannot simply vanish from.
3. Dependence on power and technical support — a CAS cannot be used at all during a power outage or system failure, and ongoing technical issues may need specialist support a manual system never requires.
4. Risk of unauthorised access or fraud — if the system's access controls (passwords, user permissions) are weak, a computerised system can potentially be tampered with more easily and less visibly than a paper ledger.
5. Risk of over-reliance reducing basic understanding — a person who only ever clicks a button to generate a Balance Sheet, without ever having worked through why an item appears where it does, may lose (or never develop) a genuine grasp of the underlying accounting principles the software is quietly applying on their behalf.
