A Computerised Accounting System (CAS) is built on five foundational components or pillars: Data, People, Procedures, Hardware, and Software.
- Data represents the financial and business information.
- People include users like accountants and decision makers.
- Procedures are standardized rules for data processing.
- Hardware includes physical components such as computers and servers.
- Software consists of accounting programs like Tally, QuickBooks, etc.
Hence, the missing pillars are: Hardware and Software.
