Computerised Accounting — an introduction

Every accounting idea covered so far in this book — the Journal, Ledger, Trial Balance, Trading and Profit and Loss Account, and the Balance Sheet — rests on the same double-entry principles whether it is done with pen and paper or with a computer. A Computerised Accounting System (CAS) does not change WHAT gets recorded or WHY; it changes HOW the recording, calculation, and reporting are carried out — using accounting software instead of manual books.

This chapter looks at CAS purely at the conceptual level: what it is, how it compares with manual accounting, its genuine advantages and real limitations, what makes up such a system, the broad types of accounting packages a business can choose from, and how a computer turns a handful of entered transactions into every report a business needs. Tamil Nadu's syllabus introduces this conceptual foundation at Class 11 — a year earlier than CBSE, which places its own Computerised Accounting coverage only as a Class 12 elective; the underlying double-entry principles both boards build on remain exactly the same.
