Computerized Accounting System

Computerized accounting systems are widely used by even the smallest of companies. These systems simplify the record-keeping process in that transactions are recorded in electronic forms at the same time, posting them electronically to general and subsidiary ledger accounts.

Computerized systems provide management with current account balance information to support decision making since account balances are posted as the transactions occur.

Computerized Accounting System

A computerized accounting system can offer many advantages; however, some problems associated with the use of computers need to be recognized.

Some of the major advantages and disadvantages are described below:


Reduction in processing costs

The low cost of hardware and software and the availability of user–friendly packages such as Xero and Reckon give computerized accounting systems a cost advantage over manual systems. Invoices can be sent electronically and paid from the customer’s mobile device eliminating the need for printing and postage.

Speed of processing

Thousands of transactions can be processed at high speed, and high‐speed printers enable output at thousands of lines per minute. In fact, there is significantly less need to print

Error reduction

Once programmed, the computer is virtually error‐free compared with manual systems, which are much more prone to human error. But control procedures must exist to ensure the accuracy of data input. Input processing is facilitated by computer help and interactive feedback.

Automatic posting

All posting is performed automatically at high speed and is virtually error‐free if the accurate data input is correct.

Automatic production of reports

The system can be programmed to produce up‐to‐date reports on request, thus providing owners/managers with more timely and relevant reports. Reports can be accessed in real-time anywhere, anytime using a mobile device. Also, various accounting documents such as invoices, cheques, and statements can be produced automatically or electronically.

Improved reporting and decision making

A wide range of reports beyond the scope of manual systems can be produced in seconds, such as analyses of sales by territory, salespeople, products and customers. The system gives greater inventory control, and detailed reports on inventory movements are instantly available.

Faster response time

A wide range of queries can be answered very quickly, such as queries from customers regarding their current balances. Stock levels of a particular item of inventory are always available.


Failed systems

Some advantages may not be realized because of hardware, software or personnel problems. Inappropriate or unsuitable programs may cause a system failure. People without the necessary expertise may also cause problems. Regular backing up of files is essential.

Power failure

Power failure, power surges and lightning strikes can cause the whole system to crash, so all systems require back‐up records.


Undetected viruses can destroy all files in the system, so security is a high priority.


Unauthorized people may gain access to computer files and make amendments, or gain access to confidential information.


People both within or outside the organization may gain access and use the computer to cover up cases of fraud or embezzlement.
