Generalized Auditing Software (GAS) is one of the families of software frequently used in computer-assisted auditing. It is a ready-to-use package that can provide a means to access and interrogate data held on computer storage media. It is one of the tools IT auditors use to obtain evidence directly about the quality of records produced and maintained by application systems. There are many GAS packages available in today’s market. However, their quality and diversity vary. It is recommended that you research various packages and talk to other users before purchasing one.
GAS consists of a series of computer program routines that can read computer files, select desired information, perform repetitive calculations, and print reports in a format specified by Auditor. Pervasive audit software allows auditors to have direct access to computerized records and effectively manage large amounts of data. Since GAS can quickly scan, test, and summarize all data into a computer file, many procedures that would normally be performed on a sample basis can be extended to the entire population. Additionally, the use of GAS generally leads to a better understanding of automated systems and computer-based operations. It can make auditing more interesting and challenging and is a great way to introduce auditors to the process of collecting evidence and verifying the integrity of electronic data files within an IT environment.
Generalized audit software can perform the following audit tasks:
1. Examine the quality, completeness, consistency and correctness of the records (check the bank’s demand deposit files for unusually large deposits and withdrawals)
2. Verify calculations and make calculations (recalculate interest, bank COT, etc. and verify payroll Net salary, Deductions, etc.)
3. Compare data in separate files (compare current and prior period inventory files for obsolete and slow moving items)
4. Select and print audit samples (accounts receivable confirmations, customer refunds over a certain amount).
5. Summarize and resequence data (resequence inventory items by location to facilitate physical observations).
6. Compare data obtained through other audit procedures with company records (compare creditors’ statements with accounts payable files).
Some advanced GASs may include a wide variety of audit functions. They allow even novice auditors to perform professional work. In addition to the wide range of auditing features and ease of use, advanced GAS can now access, analyze and report on a variety of different files held on heterogeneous hardware and software platforms that are distributed across intranet facilities. business or other means, including global computer networks. Two common names for these functions are ACL and IDEA.
GAS offers the distinct advantage over conventional programming languages of being relatively easy to learn and use. Most GAS systems require only about a week of training, and proficiency can be achieved after several weeks of use. Furthermore, coding the GAS specification typically requires a fraction of the coding inputs needed for conventional programming languages. This allows for faster coding and reduces the chance of errors.
