Computerised accounting offers several advantages vis--vis manual accounting, there are summarised as follows.
(i) Speed : Accounting data is processed faster by using a computerised accounting system that it is achieved through manual efforts. This is because computers require far less time than human beings in performing a task.
(ii) Accuracy: The possibility of error is eliminated in a computerised accounting system because the primary accounting data is entered once for all the subsequent usage and processes in preparing the accounting reports. Normally, accounting errors in a manual accounting system occur because of repeated posting of same set of original data by several times while preparing different types of accounting reports.
(iii) Reliability: The corrupter system is well-adapted to performing repetitive operations. They are immune to tiredness, boredom or fatigue. As a result, computers are highly reliable compared to human beings. Since computerised accounting system relies heavily on computers, they are relatively more reliable than manual accounting systems.
(iv) Up-to-Date Information: The accounting records, in a computerised accounting system are updated automatically as and when accounting data is entered and stored. Therefore, latest information pertaining to accounts gets reflected when accounting reports are produced and printed. e.g., when accounting data pertaining to a transaction regarding cash purchase of goods is entered and stored, the cash account, purchase account and also the final accounts (trading and profit and loss account) reflect the impact immediately.
(v) Real Time User Interface: Most of the automated accounting systems are inter-linked through a network of computers. This facilitates the availability of information to various users at the same time on a real time basis(that is spontaneously).
(vi) Automated Document Production: Most of the computerised accounting systems have standardised, user defined format of accounting reports that are generated automatically. The accounting reports such as cash book, trial balance, statement of accounts are obtained just by click of a mouse in a computerised accounting environment.
(vii) Scalability: In a computerised accounting system, the requirement of additional manpower is confined to data entry operators for storing additional vouchers. The additional cost of processing additional transactions is almost negligible. As a result, the computerised accounting systems are highly scalable.
(viii) Legibility: The data displayed on computer monitor is legible. This is because the characters(alphabets, numerals etc.) are type written using standard fonts. This helps in avoiding errors caused by untidy written figures in a manual accounting system.
(ix) Efficiency: The computer based accounting systems ensure better use of resources and time. This brings about efficiency in generating decisions, useful information's and reports.
(x) Quality Reports: The inbuilt checks and untouchable features of data handling facilitate hygienic and true accounting reports that are highly objective and can be relied upon.
(xi) MIS Reports: The computerised accounting system facilitates the real time production of management information reports, which will help management to monitor and control the business effectively. Debtors analysis would indicate the possibilities of defaults(or bad debts) and also concentration of debt and its impact on the balance sheet. e.g., if the company has a policy of restricting the credit sales by a fixed amount to a given party, the information is available on the computer system immediately when every voucher is entered through the data entry form. However, it takes time when it comes to a manual accounting system. Besides, the results may not be accurate.
(xii) Storage and Retrieval: The computerised accounting system allows the users to store data in a manner that does not require a large amount of physical space. This is because the accounting data is stored in hard disks, CD-ROMs, floppies that occupy a fraction of physical space compared to books of accounts in the form of ledger, journal and other accounting registers. Besides, the system permits fast and accurate retrieval of data and information.
(xiii) Motivation and Employees Interest: The computer system requires a specialised training staff, which makes them feel more valued. This motivates them to develop interest in the job. However, it may also cause relationship when we switch over from a manual system to a computer system.
