They are typically derived from sources like the payroll system, financial statements, reports, sales and purchase data, invoices, inventory , etc.

A user friiendly database structure is designed to store related information, which has the facility of addition and alteration. However, it is necesaary to make the platform highly secured and free from cyber attaks, viruses and hackers, who attempt to collect useful and confidential data and misuse them for their own interest.

The role of cybersecurity has increased considerable ever since businesses have started shifting their data to electronic form and taking the help of softwares and technology to get the jobs done. Even though it has undoubtly increased the speed and accuracy levels of work, external threat have also increased alone with it.

The AIS is a process that can generate reports based on the data provided that can be used further for deriving conclusion and decision making regarding investments and projects.


The AIS is considered to have the following three types, as explained in details below:

  • Manual – As the name suggests, the system is managed on a manual basis, with the use of documents like journal, ledger, invoices, bills, sales and purchase order details, subsidiary and special journals, etc. There is no influence of technology and there is no integration of hardware and software in the process. Small businesses mainly use this method, since their transaction and operational procedures are not very vast, widely spread and complex.
  • Legacy – This system is named so due to the fact that is has been in existence in the accounting system before the influence of technological procedures were introduced. Its main benefit and positive side lie in the fact that it is very easy to use and implement historical data plays a major role in it. But in terms of reliability and flexibility, ir cannot match the levels of modern software and advanced technology. It can be customized according to the firm’s needs and requirements. This flexibility usually not found in standardized software, which are typically used by many businesses. However, it should be noted that it is not easy to find or update the software and hardware used in the system, which may over the time become obsolete.
  • Modern – They are considered easy to handle and install in the business and is more user-friendly that the Legacy System. They are Windows based, which can be used and interpreted by many, as well as cheap from the costing point of view. Th security measures can also be implemented on them very easily.

Thus, the above are the various types of AIS that are prevalent in the market. However, they have evolved over time and lot of more major, interesting and useful changes can be expected in the years to come.

Let us understand the concept with the help of a suitable example as given below:


The system has some advantages and disadvantages of its own. Let us learn the advantages first.

  • #1 – Cost-Effectiveness – In the era of digitalization and artificial intelligence, each organization is moving towards cost-cutting using artificial intelligence. AIS has helped reduce manual efforts and can perform the same operation more cost-effectively.
  • #2 – Time Effectiveness – AIS has assisted business organizations in reducing the amount of time involved in recording, classifying, and reporting any financial information. AIS can complete a large quantum of manual work with much less effort and time.
  • #3 – Easy Access(Portability) – Data stored in AIS can be retrieved via an information system connected to the internet anywhere and at any time. Where manually prepared books of accounts cannot be carried easily, AIS data can be.
  • #4 – Accuracy – With the involvement of AIS, the reliability of data is increased. As discussed earlier in this article, an AIS follows a predefined set of instructions. Therefore chances of error-prone information are less, and therefore AIS has an added advantage of accurate data.


Some noteworthy disadvantages of the concept are as given below:

  • #1 – Initial Cost of Instalment and Training – While we discussed that an AIS is cost-effective, the same may not be accurate in the case of small business enterprises. The initial setup cost may be high and may not generate value for the organization.
  • #2 – Manual Intervention – Although we discussed that AIS reduces manual intervention, the same cannot be eliminated. AIS needs manual intervention at a certain point, which may bring inefficiency to the system.
  • #3 – Error Cannot be Completely Eliminated – We discussed that AIS reduces the chances of error, but there are chances of wrong coding in software, which may lead to error-prone results. Also, manual intervention is still present here, generating an error.
  • #4 – Confidentiality – Although we discussed the portability of AIS data, the same can also be disastrous for an organization If such information is hacked, i.e., stolen. An intruder may amend the information or can disclose sensitive financial information.
  • #5 – Virus Attack – Any data stored on IS can be infected with a virus that may disrupt and modify financial information stored on AIS.
  • Cost: We already discussed the cost of AIS as a disadvantage.
  • Training: There is a need to train users to feed, retrieve, or use AIS in the desired manner. If the concerned person does not get trained well, it can lead to inaccurate data preparation and presentation. Also, there are frequent transfers, promotions, resignations, retirement in a large organization. In all these cases, there is a regular need for training for replacements.
  • Obsoletion: In the era of digitalization, technology is changing at a swift pace. It takes very few moments for technology to get obsolete. This generates needs for an organization to adopt the changes at the earliest. Otherwise, it may lead to error-prone data.

It is necessary to understand the advantages and disadvantages of the concept in detail so that the system can be implemented and used as per the nature and size of the business and also its requirements.

Change In Accounting Information System (AIS)

In the era of rapidly changing technology and adaptation of technological advancements, significant changes are occurring in AIS. The latest changes include cloud computing, cloud accounting, real-time accounting, or mobile accounting.

This has made accounting much easier and more convenient than the old ways of accounting. Advancement has reached a level that records, classifies, analyses, and reports figures and predicts future trends, which may help to face an actual situation with much preparedness.

Accounting Information System (AIS) can be described as a boon to any organization as we studied both advantages and disadvantages, limitations of AIS. However, overall it is very beneficial for an organization to migrate from manual accounting to AIS-based accounting. For overcoming various disadvantages, and limitations of AIS, there is software that secures the organization’s AIS from viruses, hackers, and other attacks.

Artificial Intelligence, an extended version of the Accounting Information System (AIS), has already started reducing manual intervention and will grow at a breakneck pace soon.
