Computerized Accounting System

Computerized Accounting System (CAS) is an accounting information system that processes financial transactions using computer hardware and specialized accounting software to produce accounting records and reports. Instead of using traditional paper-based ledgers and journals, transactions are entered digitally, and the software automatically performs tasks such as:

• Recording transactions in journals and ledgers.
• Performing complex mathematical calculations.
• Generating essential financial reports like the Trial Balance, Profit and Loss Statement, and Balance Sheet.

This system adheres to generally accepted accounting principles (GAAP) to provide accurate and up-to-date financial information for decision-making.

Key Differences from Manual Accounting System

The Manual Accounting System is the traditional method that relies on paper, journals, and ledgers, with all calculations and postings performed by hand. The shift to computerized accounting offers significant advantages:

Fundamental Accounting Assumptions

The Fundamental Accounting Assumptions are the basic rules or concepts that are presumed to have been followed when preparing financial statements. They provide a foundational framework for making the statements reliable, consistent, and comparable, unless otherwise explicitly disclosed.

There are three primary Fundamental Accounting Assumptions:

Going Concern Assumption

Concept: Assumes that the business enterprise will continue its operations for the foreseeable future and has no intention or necessity to liquidate or significantly curtail its scale of operations.

Impact: This justifies recording fixed assets at their historical cost (minus depreciation) rather than their liquidation value, as the business is expected to use them over their entire useful life.

Consistency Assumption

Concept: Requires that the accounting policies and practices selected by an enterprise be applied uniformly from one accounting period to another.

Impact: This allows users to compare the financial results of different periods effectively. If a change in policy is made, it must be fully disclosed in the financial statements.

Accrual Assumption

Concept: States that revenues are recognized when they are earned and expenses are recognized when they are incurred, regardless of when the cash is actually received or paid.

Impact: This provides a truer picture of a company’s financial performance by matching revenues and expenses to the correct period in which they relate, not just when the cash flows.

4. Install the Application:
   • The Setup Manager will typically recommend a default installation path. If you are installing it for the first time, select “Install New”.
   • Optional: Press C (Configure) if you need to change the application installation path or other settings.
   • Press I (Install) to begin the installation. The process will complete in a few moments.
5. Launch TallyPrime:
   • Once the installation is complete, click “Start TallyPrime” or press S to launch the application.
6. Activate License:
   • Upon launching, you will be prompted to choose an option:
   • Activate New License
   • Use License from Network
   • Continue in Educational Mode
   • If you have a license, choose “Activate New License” and enter your Serial Number, Activation Key, and Administrator Email ID. Tally will send an Unlock Key to your email, which you must enter to complete the activation.

Data Processing in a Computerized Accounting System

In a Computerized Accounting System (CAS), data processing is the systematic conversion of raw financial data (like transaction details, invoices, and receipts) into meaningful, usable accounting information (like ledgers, trial balances, and financial statements) using computer hardware and software. It is a multi-step cycle performed automatically by the accounting software, which greatly enhances the speed, accuracy, and efficiency of the accounting process compared to manual methods.

The process generally follows these stages:

• Data Collection/Input: Raw data (e.g., sales transaction details, employee payroll data, purchase invoices) is gathered from source documents and entered into the computer system, typically through a keyboard, scanner, or by importing files.
• Data Preparation/Cleaning: The system validates and cleans the raw input data, checking for errors, inconsistencies, or redundancy (e.g., ensuring debit equals credit in a double-entry system).
• Processing: The accounting software applies various calculations, sorting, and transformations to the cleaned data based on the established accounting principles and rules. In this stage, the software automatically:
  • Posts transactions to the relevant ledger accounts.
  • Calculates totals, balances, and depreciation.
  • Aggregates and summarizes data for reporting.
• Data Output/Reporting:

  The processed data is converted into a structured, readable format, such as financial statements, reports, graphs, and summaries, which can then be used by managers and stakeholders for decision-making.

• Data Storage:

  The processed data and the final reports are stored securely in databases for future retrieval, reference, auditing, and backup purposes.

Components of an Accounting Information System (AIS)

An Accounting Information System (AIS) is a system of collecting, storing, and processing financial and accounting data that is used by decision-makers. For a CAS to function effectively, an AIS typically includes six critical components:

• People 🧑‍💼

  The users of the system, including accountants, managers, business analysts, auditors, and IT staff, who input data, operate the system, and utilize the generated reports for decision-making and compliance.

• Procedures and Instructions 📜

  The policies, rules, and methods that govern how the AIS operates. This includes both manual and automated procedures for collecting, storing, retrieving, processing, and reporting data, ensuring consistency and adherence to accounting standards (like the Double-Entry system).

• Data 🔢

  All the financial and operating facts and figures that flow through the system. This includes raw transaction data (sales, purchases, payroll), journal entries, ledger balances, budgets, and historical records.

• Software 💻

  The computer programs and applications (like TallyPrime, QuickBooks, SAP, or Oracle) used to process the accounting data, perform calculations, manage databases, and generate reports. The software is the heart of the CAS.

• Information Technology (IT) Infrastructure 🌐

  The hardware and network systems that support the AIS. This includes computers, servers, routers, printers, storage media, and the network that connects these devices.

• Internal Controls 🔒

  The security measures and checks put in place to safeguard the system’s data and assets, ensuring the accuracy, reliability, and validity of the information. Examples include access controls, user authentication (passwords), encryption, and reconciliation procedures.

These six components work together to form a robust system that transforms raw data into valuable financial information.
