Computerised Accounting System
Computerised accounting tests whether you understand how software records and reports transactions, not whether you can press buttons.
Components
A computerised accounting system has hardware, software, people (users and IT staff), procedures, data and connectivity. The data flow is: source document → voucher → ledger → trial balance → financial statements. Accounting software stores data in a database - related tables managed by a database management system - so one voucher entry automatically updates every ledger and report that draws on it.
Types of software
Readymade or generalised packages are cheap and quick to install but may not fit unusual requirements. Customised software is a readymade package modified for the business. Tailor-made or bespoke software is built specifically for the organisation, at high cost and effort. Enterprise resource planning integrates accounting with inventory, payroll and production. Features to check: access control and security, audit trail, backup and restore, multi-user support, GST-compliant invoicing and MIS reports.
Worked example
A partnership with three branches and GST billing needs multi-user access, automatic return preparation and an audit trail. A readymade package meets the cost and timeline test; tailor-made software is justified only if the firm's processes are genuinely unusual. Setting it up means defining the chart of accounts - groups such as assets, liabilities, income and expenses first, then ledgers under them - so that every report is generated correctly from the same data.
Traps
Confusing accounting software with the operating system; assuming computerised records cannot be wrong, when wrong input produces wrong output; ignoring backup and user access control; treating a database as the same thing as a spreadsheet.
