Meaning, Features and Advantages of Computerised Accounting System

A Computerised Accounting System (CAS) is a system of maintaining a business's books of accounts using a computer and dedicated accounting software, rather than writing entries by hand into physical registers. Transactions are entered once into the software, and the software itself carries out the classification, posting, and summarisation that a manual system would otherwise require a person to do step by step. The same universal double-entry principles you have studied throughout Accountancy — in the CBSE/NCERT Commerce curriculum as much as in TN's own syllabus — remain exactly the same; only the method of recording and processing them changes.

Features of a Computerised Accounting System

• Speed — transactions are processed and reports generated almost instantly, far faster than manual posting and balancing.
• Accuracy — once a transaction is entered correctly, the software performs all subsequent calculations and postings without arithmetic or copying errors.
• Integration ('single entry, multiple reports') — a single voucher entry automatically updates every relevant ledger and every report that depends on it (Trial Balance, Profit and Loss Account, Balance Sheet), without any separate manual step for each.
• Storage and retrieval — large volumes of data can be stored compactly and retrieved instantly by date, ledger, or voucher type, rather than searched for page by page in physical books.
• Real-time information — management can view the firm's current financial position at any moment, not only after a period-end closing exercise.
• Data security — access can be restricted with passwords, and data can be backed up to prevent loss.

Advantages flowing from these features include: substantial time and labour saving, higher reliability of figures, easy generation of a wide range of reports (including for statutory compliance such as GST returns) at the click of a button, reduced paperwork and physical storage needs, and better support for prompt, informed managerial decision-making.
