AUDITING & ACCOUNTING INFORMATION SYSTEMS
ACCOUNTING INFORMATION SYSTEMS (AIS) I.C.W. AUDIT
INHOUD
- Accounting system
- Revenue system
- Expenditure system
ACCOUNTING SYSTEM
Auditor: checks financial statements before it goes public.
- Important because investors use financial statements to make decisions
- Auditor cannot guarantee everything is correct, they give assurance to consumers/investors
that the numbers are reliable
- They do not check every single number but the total post at balance sheet
- Auditor ≠ Accountant
o Auditor is één ding: degene die de jaarrekeningen controleert en ingehuurd wordt
door een bedrijf
o Accountant kan van alles zijn: management accountant, bookkeeper (boekhouder)
ACCOUNTING INFORMATION SYSTEMS (AIS)
Accounting: the process of identifying, measuring and communicating economic information to
permit informed judgements and decisions by users of the information.
Accounting is an information-providing activity, so accountants need to understand:
o How the system that provides that information is designed, implemented and used.
o How financial information is reported.
o How information is used to make decisions.
Accounting information system: tool for auditor to get the info etc, the environment within
accounting exists. An auditor checks the numbers by checking the systems from where the numbers
come from. When the system is correct, it is quite likely the numbers that come from the system are
also correct.
EXAM QUESTION
- Text is given, asked to write/draw the model
- Model is given, asked: how to improve?
,HC1: AN INTRODUCTION TO AIS
LEARNING GOALS
At the end of this lecture, you should be able to:
- Understand the information flows within the business
- Discuss an information system
- Explain an accounting information system
- Discuss the 3 AIS subsystems (transaction processing system, general ledger / financial
reporting system, management reporting system)
INFORMATION SYSTEMS (IS)
INFORMATION
Data: facts, figures (mostly not useful)
Information: data represented in a form useful for decision making. Information is useful because it
can be used to control people. It is a business resource and important for all parts of an organisation.
System: a system consists of interdependent elements and is set up to achieve one or more specific
objectives. It is a group of two more elements that work together
- Systems can exist of subsystems, these subsystems help to reach the purpose of the system
- There is a system when:
o Two or more components (students and professor)
o Interrelationship (there is communication)
o Common goal (goal is to learn something)
Information system (IS): a set of interrelated subsystems to collect, store and manage data and to
provide output information to users and helps to plan, make decisions and control processes.
- bv. information systems processes
o financial transactions → goes to auditor
o nonfinancial transactions
,MANAGEMENT INFORMATION SYSTEMS
Management information system: process nonfinancial transaction that are not normally processed
by accounting information systems.
– Financial management system
– Marketing systems
– Distribution systems
– HRM systems
1. External and internal users
2. External and internal sources of
data
3. Data collection
4. Data processing
5. Data base management
6. Information generation
7. Feedback
Enterprise Resource Planning system (ERP system): software package that can be used for the core
systems necessary to support enterprise systems. Software that collect data and report information.
- Centralized database to share info across business
- Designed for efficient and effective coordination of activities
- Important because one activity that is part of one business process often triggers a complex
series of activities throughout many parts of the organization
ACCOUNTING INFORMATION SYSTEMS (AIS)
DEFINITION
Accounting information system (AIS): specialized subsystem of IS
- The purpose of the AIS is to collect, process and report information related to the financial
(accounting) aspects of business events.
- When an ERP system is related to financial (accounting) aspects of business events → AIS
, Accounting information systems supports
– The stewardship-function of the management
– Management decision making
– The firm’s all day business
COMPONENTS OF AIS
- People
- Procedures and instructions
o for example you need a procedure to grade students
- Data
o you need a relevant database to analyze what you want to know
- Software
o do we only use excel or also something else?
- Information technology (IT) infrastructure
- Internal control (IC) and security measures
o for example how to protect that no one else can change your grade on the internet
o security also makes your employees aware of the risks
USES OF AIS
- Producing external reports
- Supporting routine activities
- Decision support
- Planning and control
- Implementing internal control
- Adding value to organization
o Reduce costs of products and services
o Shares knowledge
o Improves
▪ Quality
▪ Efficiency
▪ Effectiveness of it’s supply chai
▪ Internal control structure
▪ Decision making
• Identifying problem
• Collect/interpret info
• Evaluate alternatives
• Enz..
