Hidden Risk factors in Computerised Accounting System
Computerised Accounting systems
Digital accounting has fundamentally changed the way financial records are created, modified, and reported. Unlike traditional manual accounting, where every correction leaves a visible audit trail, computerised systems can instantly update transactions and financial statements across the entire database. Certain advanced features available in accounting software may provide operational flexibility, but they demand stronger governance and internal controls. This chapter examines some features and explains why management, auditors, and regulators should understand their implications to safeguard the integrity, reliability, and legal compliance of financial reporting.
Manual Accounting vs Computerised Accounting systems
Manual accounting systems maintain permanent books of account. Once recorded, these cannot be modified. Every correction required a rectification entry, creating a visible audit trail that preserves the history of changes.
Computerised accounting systems have transformed business operations. They offer speed, automation and powerful reporting. However, digital records can be modified, overwritten or deleted, with all reports immediately reflecting the revised data. Unless supported by robust audit trails, internal controls and disciplined procedures, even significant changes may not leave visible evidence, or even trace for suspicions for management or auditors.
For this reason, management, auditors and regulators should understand not only accounting principles, but also the operational behaviour of accounting software.
Some instances are described here, to reinforce, how strong governance is essential in some key areas. Check how the software system treat such cases, and be aware of their implications.
Reverse Accounting through Report-Level Operations
Accounts are compiled from transactions. So, Reports are results of Transactions. In case of mistake, specific vouchers is edited indecently.
Some Software systems allow drill down from financial reports to underlying vouchers, and add, delete, cancel transactions, to produce desired financial reports. Transition records may be inserted / altered / deleted from Reports. Hence the concept of Reverse Accounting.
Implication
Unrestricted voucher operations may create door ways of manipulation and security issues. Accounts may be easily created and modified reverse way, from reports to vouchers. These actions pose serious security issues. Such actions should be totally prohibited / disallowed, or strictly controlled, ensuring every modification is properly authorised, logged and reviewed.
Automatic Financial Year Closing Entries
In traditional accounting, year-end adjustments are normally recorded through identifiable journal entries.
Some Software, internally compute profit/ Loss on the fly, by-passing conventional Journal Book entries.
Implication
Although operationally simple, management should verify how closing adjustments are processed and whether sufficient audit evidence exist for such adjustments.
Independent Closing Stock Values
In Integrated Accounts & inventory systems, Closing Inventory value is auto carried directly from inventory records. to Financial Accounting Module, without manual intervention
Some Software systems, allow users to manually input Closing Inventory value, unsupported by Inventory records. Such input Stock values are reflected in Financial Statements.
Implication
Differences between inventory records and financial statements would arise if such facilities are not adequately controlled. Inventory valuation should always remain supported by documented inventory records and approved valuation policies.
Dynamic Profit / Loss Adjustments
In Companies, Profit/ Losses are transferred between Reserves, In Proprietorship/ Partnership, Profit /Loss may be carried to Capital. Such transfers & Adjustment are recorded through Journal, under strict management approved polices and rules.
Some Software like Tally allows repeated transaction modification and dynamic Profit / Loss adjustments, without any accounting records in Books.
Implication
Repeated modifications cause continuous alteration of profits / loss and its adjustment, by-passing accounts books records. Periodic review of audit logs and post-closing changes therefore are important.
Voucher Number Management
Voucher Number is one of the strong audit control mechanisms, to track Insertion, Deletion, Cancellation, Modification of Vouchers.
Some software systems offer wide variety of unusual voucher numbering methods, like mix of manual numbering, renumbering, multiple voucher series, skipped numbers, back-dated insertions, deleted and skipped number re-use, etc.
Implication
These facilities may provide operational flexibility, but likely to weaken established control system. Organisations should establish clear and secured voucher numbering policies, strict control on voucher operations, regularly review & track exceptional entries.
Dynamic Inventory Valuation Methods
Modern accounting software often support multiple inventory valuation methods, for management analysis, etc. As per Accounting Standards, the Inventory valuation must be consistently applied. If there is any deviation, it should be properly disclosed in Financial Report. It is joint responsibly of both Management and Auditors for compliance.
Some Software allow to change Inventory valuation method freely. Software systems compute Inventory Value at Stock Item level, dynamically, as set & reset by user. An organisation may hold several thousand Inventory Items. Valuation method may be changed, without any mechanism to restrict, warn or identify different valuation method.
Implication
Frequent changes in valuation methodology may affect reported profits and inventory values. Management should ensure consistency with applicable accounting standards and document every authorised change. Software should be able to track, report Inventory Valuation Methods and identify anomalies.
Location-wise Inventory Valuation
Due to storage facilities constraints at one place, materials may be stored, into multiple partitions or godowns, in the factory, and maintain stock for each space, for physical handling and stock counting. But the stock and value mut be computed uniformly, irrespective of place of storage.
However, some Software automatically treats stock at each place as separate, and value them separately. Where price fluctuate frequently, the average price computed for each location may vary considerably.
Implication
Where stock is spread in multiple distinct places, anomaly in average closing stock price for different marked places must be audited & verified. Stock value should be recomputed properly and adjustments must be made in accounts for difference in stock valuation.
Report Display Controls
Computer reports are treated as infallible, sacrosanct, undisputed.
Certain software systems allow users to customise reports by hiding selective portions in report.
Implication
This causes extra responsibility to Auditors whether they are being misled with doctored reports. They should check and cross verify the control figured to ensure that the report has no been manipulated.
Responsibilities of Management
This chapter reveals some hidden and unknown issues of Accounting Software for general awareness. Management should establish strong internal controls over:
- User access rights
- Voucher alteration permissions
- Back-dated entries
- Audit trail review
- Inventory valuation policies
- Period closing procedures
- Report authentication
- Backup and record retention
- Data Hide / unhide in Reports
Technology cannot replace governance. Reliable financial reporting depends upon disciplined accounting processes supported by appropriate system controls.
Responsibilities of Auditors
Similarly, more responsibility lay of Auditors. The auditing should extend beyond verifying accounting entries, but also evaluate:
System configuration
User permissions
Audit trails
Post-closing alterations
Inventory valuation consistency
Voucher numbering controls
Data hiding in Reports
Internal control effectiveness
Understanding how accounting software operates is as important as understanding accounting standards themselves.
Final Thought
Computerised accounting systems provide tremendous flexibility and efficiency. The same flexibility, however, demands stronger governance, better internal controls and greater professional awareness.
The integrity of financial reporting depends on software systems, as well as how organisations configure, control and use it.
