Computerised systems for Financial Transactions

1. Faster, more accurate processing of transactions with automatic double entry.
2. Instant financial reports (e.g. statements and aged receivables) for better decision-making.

1. Passwords (changed regularly) to restrict access.
2. Access levels / user rights limiting what each user can do.
3. Regular back-ups stored off-site or in the cloud.
4. Anti-virus software and firewalls to block malware and unauthorised access.

1. Cost. The hardware, software and ongoing upgrade costs, plus staff training, may be too expensive for a small business with a low volume of transactions, so the benefits may not justify the outlay.

2. Risk and disruption. The business becomes dependent on IT (power cuts/crashes stop work), faces data-loss and security risks, and the disruption and learning time of changing systems may outweigh the gains for a simple business.

1. Regular back-ups (off-site/cloud). A copy of the data means that if files are lost or corrupted (e.g. by a crash or fire) the records can be restored, avoiding permanent loss.

2. Passwords and access levels. Restricting who can view or change data prevents unauthorised access and fraud; staff only access what their role requires (segregation of duties).

3. Anti-virus software and firewalls. These block malware and hacking attempts, protecting the data from external attack and corruption.

Arguments in favour.

• Accuracy: automatic double entry would reduce the posting errors the business currently suffers.
• Speed & capacity: a computerised system handles a high volume of transactions far faster than manual records.
• Better information: instant reports (trial balance, statements, aged receivables) support management decisions and control.

Arguments against / costs.

• Cost of hardware, software and training.
• Risks: dependence on IT, data-loss and security/fraud risks needing back-ups and access controls.
• Disruption during the changeover (links to 3.4 — transferring data accurately).

Judgement. Given the high transaction volume and frequent errors, the directors should introduce a computerised system: the gains in accuracy, speed and information clearly outweigh the costs for a business of this size. The recommendation holds provided the data is transferred carefully and proper back-up and security controls are put in place.

What does not change. The system still applies the double entry principle (equal debits and credits) and the same accounting concepts (matching, prudence, etc.), and it produces the same outputs — ledgers, trial balance and financial statements. The accounting is identical.

What does change.

• How the work is done: data is entered once and the software posts automatically to all ledgers, produces reports on demand, and stores data electronically — far less repetitive manual work.
• How it is controlled: controls shift from manual checking to IT controls — passwords, access levels, back-ups, anti-virus and audit trails — and the business becomes dependent on the system working reliably.

Conclusion. The principles and outputs are unchanged; what changes is the efficiency of processing and the nature of the controls and risks the business must manage.

1. It completes the double entry automatically, so posting and arithmetic errors are reduced.
2. It performs calculations and additions automatically (e.g. totals, balances, the trial balance), removing manual arithmetic mistakes.

1. Reconcile control account totals. Check that the sales ledger and purchases ledger control account totals produced by the new system equal those in the old system; agreement confirms the personal accounts were transferred in full.

2. Agree the trial balance. Ensure the trial balance generated by the new system matches the closing trial balance of the manual system, confirming all balances were entered with equal debits and credits.

3. Verify samples and run in parallel. Check a sample of individual balances against the manual records, and run both systems in parallel for a period, comparing outputs before relying solely on the new system.

How it strengthens control.

• Access levels and passwords enforce segregation of duties — staff can only perform tasks their role permits.
• An audit trail automatically records who entered or changed each item, deterring and detecting manipulation.
• Automatic processing removes many arithmetic errors and produces reconciliations and control accounts quickly.

How it weakens control.

• The business becomes dependent on the system and on those who administer it; system failure halts work.
• If access controls are weak, one person could alter many records quickly (or a hacker could), and the visible paper trail may be reduced.
• New risks arise — viruses, hacking and data corruption.

Conclusion. Control improves only if the IT controls (passwords, access levels, back-ups, audit trails) are well designed and enforced; the technology alone does not guarantee good control.

Arguments in favour. A computerised system would give faster, more accurate processing and instant reports, and would cope with future growth more easily than manual records.

Arguments against (more relevant here).

• With a low volume of transactions, a manual system may already be adequate, so the benefits are limited.
• The business has limited funds, so the large cost (plus training and security) is a significant burden.
• It adds data-loss and security risks and dependence on IT.

Judgement. Given the low transaction volume and limited funds, the cost is likely to outweigh the benefits at present, so the business should probably not computerise yet — unless it expects significant growth, in which case investing now could be justified. A cheaper or scalable option (e.g. low-cost software) might be a better first step.
