Advantages and Limitations of a Computerised Accounting System

Like any tool, a computerised accounting system brings real benefits but also real limitations, and a good answer should be able to state both honestly rather than treating computerisation as an unqualified improvement.

Advantages

• Speed. Vouchers are posted, ledgers updated and reports generated far faster than by hand.
• Accuracy. The software performs every calculation, removing the casting and carry-forward errors common in manual books.
• Up-to-date information. A trial balance or a customer's outstanding balance can be checked at any moment, not only at the end of a period.
• Storage and retrieval. Years of accounting data can be stored compactly and any past entry retrieved almost instantly.
• Quality of reports. Beyond the basic financial statements, the same data can be analysed in many ways — ageing of debtors, profitability by product line, branch-wise performance — without re-entering anything.
• Scalability. The system can absorb a growing volume of transactions far more easily than a manual system can absorb more clerks and more ledgers.
• Easier statutory compliance. GST returns, TDS statements and other periodic filings are easier to prepare when the underlying data is already computerised.
• Automatic backup. Data can be duplicated and stored safely, guarding against the physical loss that destroys paper books permanently.

Limitations

• Cost. Hardware, software licences, and staff training all require an upfront investment that a very small business may find hard to justify.
• Dependence on power and technical skill. The system cannot function during a power failure or a hardware breakdown, and staff need at least basic computer literacy to operate it.
• Risk of data loss or corruption. A virus, a hardware failure, or a software crash can damage data if regular backups are not taken.
• Risk of fraud or unauthorised access. Weak passwords or poorly defined access rights can allow data to be altered or deleted without a trace.
• Resistance to change. Staff used to manual methods may resist adopting a new system, at least initially. …
