So What is Accounting Information System?

• Accounting Information system is the set of computer based tools to collect, store, and process transaction data and communicates financial information to decision makers.

• In addition, the system greatly contributes to preparing different reports.

• Accounting information system is a computer based tool which is widely used in business. It helps to interact with customers and suppliers. Likewise it helps in competing and running business smoothly. For example the co-operative sector put details on the web through information system to interact with their customers, Government used AIS to provide services to their citizen, to get the information about the nation economy and to collect tax.

• The accounting information system is in close connection with the management information department, the accounting and administration department, the inner control and the information technology  team.

• Parts of  an accounting information system might include financial reporting, cost accounting, management accounting and enterprise resource planning (ERP). A well- designed AIS gives a business a consistent way to view and analyze financial information.

Accountants’ role in the AIS

• As Designers
• As Implementers

• As Auditors

• As User
• As Owners

Reasons for Studying Accounting Information Systems

• Career accountants will be users, auditors, and developers of AIS

• Modern-day AIS are complex because of new technologies System elements

• Input
• Memory

• Process

• output

Data & Information

• Data are facts that are collected, recorded, stored, and processed by an information system. Organizations collect data about event that occur, resources that are affected by those events and agents who participant in the event.

• Information is different from data, information is data that has been organized and processed to provide meaning to a user. Usually more information and better information translate into better decisions.

Functional Steps in Transforming Data into Information

• Data collection - capturing, recording, validating and editing data for completeness and accuracy

• Data Maintenance/Processing - classifying, sorting calculating data

• Data Management - storing, maintaining and retrieving data

• Data Control - safeguarding and securing data and ensuring the accuracy and completeness of the same

• Information Generation - interpreting, reporting, and communicating information

Essential element of best AIS

• Hardware
• Software

• Database

• Telecommunication
• People

• Procedure

Users of accounting information System

• Internal: are those that are part of the firm and whose decisions affect the running of the firm. This includes the board of directors,
the executive committee, the CEO, management and the people who
work for the firm.

• External: are agents that are not active participants in the running of the firm, but are affected by the decisions its makes.
o The stakeholders of a firm are agents who are interested in the running of
the firm because the decisions they make are directly affected by the success
of the firm. The most important stakeholders of a firm are its shareholders

Data Conversion




Improve Decision making


System & Subsystem

• The subsystems should be designed to maximize achievement of the organization’s goals.
• The system concepts encourage integration for example minimizing the duplication of recording, storing, reporting, and processing.

What is the benefit of dividing a system into subsystems?

• Goals:
–Satisfy the requirements
–Satisfy the customer
–Reduce development costs
–Provide reliability
–Support maintainability
–Plan for future modifications

Transactions Processed by the Information System

Financial Transaction and non- Financial Transaction

◦  A transaction is a business event.
◦  Financial transactions
◦ economic events that affect the assets and equities of the organization
◦ e.g., purchase of an airline ticket
◦  Nonfinancial transactions
◦ all other events processed by the organization’s information system
◦ e.g., an airline reservation — no commitment by the customer

AIS Composed of three major subsystems on organization

•   Transaction Processing Systems (TPS)
•   Management Reporting system (MRS)

•   General Ledger/Financial reporting System (GL/FRS)

equity at the time of the event.
• Basic business operations such as customer orders, purchase orders,
receipts, time cards, invoices, and payroll checks in an organization.
