Accounting information system (AIS)

An accounting information system (AIS) is a system used to store, sort, and view financial information for a company or other organization. Although early systems used paper, modern systems are generally computer based and thus must be implemented using a combination of accounting knowledge and computer-science skills. An AIS allows users to input large amounts of accounting data and sort that data so it can be read and interpreted more easily. Such systems typically enable users to create condensed reports for review by accountants, tax agencies, or people tasked with making decisions about a company’s financial future.

Overview

For a company or organization that carries out numerous financial transactions, accurate and efficient accounting procedures are critical. Large amounts of financial data must be organized and stored so that they can be readily accessed at any time. To collect all the necessary data, companies typically use an accounting information system (AIS) to collect, store, and sort this information. The term “accounting information system” often refers not only to the software, infrastructure, and internal controls (i.e., security measures) necessary to the system but also to the people who input and view the data, the procedures used to collect and process the data, and the data themselves.

Financial data collected in an AIS may include inventory and sales figures, payroll information, and tax records. As the data collected are typically extensive, the AIS is usually designed to facilitate the creation of condensed reports that provide essential data in a format that is easy to read and interpret. Accountants and auditors might review these data to determine whether payroll is being carried out correctly or to investigate potential fraud, while individuals employed by tax agencies might review data to ensure that income and expenses are being accurately reported and the proper taxes are being paid. Financial data are especially key for investors interested in potentially investing in a company and for company owners or managers who make decisions regarding staffing and projects based on the company’s overall financial well-being.

Early accounting information systems were based on paper account books and ledgers. Since the advent of computers, accounting practices have mixed with computer technology to create functional systems for processing financial data. Computer-based systems, which typically use complex database software, may be designed by in-house or hired developers for a specific company or purchased from a technology company such as Microsoft or Oracle. To operate a complex system that processes a large amount of data, a company or organization must first establish the proper computer infrastructure, ensuring that all hardware is up to date and optimized for such work. Otherwise, the software itself could operate slowly or improperly, thus reducing the efficiency of the entire AIS.

By the early 2020s, some companies had begun experimenting with the integration of artificial intelligence (AI) technology, including large language models, into their AIS to potentially make the systems even more efficient and real time. At the same time, cloud-based account information systems had become increasingly accepted and utilized.
