Ünite 6: Accounting/ Finance Information Systems

Historical Nature of Accounting Data
As noted by Sürmeli (2009), accounting data is historical, meaning reports reflect past transactions. However, this historical information is the foundation used by managers to protect assets, control current operations, and plan future activities.
Accountant Roles in Modern Systems
According to Gelinas and Dull (2008), modern business environments require accountants to act as system designers, users, and auditors. They must design system controls to ensure reports are exact, valid, and accurate.
Perry and Schneider Database Model
The 2002 database model by Perry and Schneider demonstrates that a single sales transaction generates interconnected records across multiple tables, including tblCustomer, tblSales, tblInventory, and tblPersonnel.
The Three Subsystems of AIS
James A. Hall (2008) categorizes the AIS into three distinct subsystems: the Transaction Processing System (TPS), the General Ledger/Financial Reporting System (GL/FRS), and the Management Reporting System (MRS).

Anahtar Kavramlar

Accounting Information System (AIS)A specialized subsystem of management information systems that collects, processes, and transforms financial data from business operations into actionable financial information and reports for decision-makers.
Transaction Processing System (TPS)A major subsystem of AIS that converts economic events into financial transactions, records them in journals and ledgers, and communicates the information to support daily business operations.
Revenue CycleThe cycle within the transaction processing system that deals with sales and sales-related activities, starting with receiving a customer order and ending with cash collection.
Expenditure CycleThe cycle that handles purchasing operations for required inputs such as raw materials, finished goods, services, fixed assets, and payroll payments.
Conversion CycleThe cycle that monitors the physical workflow of the manufacturing process, transforming raw materials, labor, and overhead into finished products while generating cost information.
General Ledger/Financial Reporting System (GL/FRS)The system that aggregates data from various transaction cycles, updates the general ledger accounts, and prepares formal financial statements primarily for external users.
Management Reporting System (MRS)A system that generates internal, often confidential reports such as budgets, cost analyses, and cash flow statements specifically tailored to the information needs of internal managers.
DocumentationThe process of defining a business transaction by identifying its parties, date, subject, quantity, and amount, which serves as the primary input for the accounting system.
Sales OrderA document prepared upon receiving a customer order that contains detailed information about the customer, the items ordered, delivery dates, and the total amount.
Approved Sales OrderA sales order that has been reviewed and authorized by the credit department, confirming the customer's creditworthiness and allowing the transaction to proceed.
Packing SlipA document prepared by the warehouse that lists the specific items and quantities included in a shipment, used by the shipper and the customer to verify the delivery.
Bill of LadingA formal contract between the seller and the carrier that details the terms, destination, and contents of the shipment, serving as proof of receipt by the carrier.
Purchase RequisitionAn internal document prepared by inventory control or a department manager to request the purchasing department to buy necessary materials or goods.
Purchase OrderA formal document sent by the purchasing department to a vendor, specifying the materials required, prices, delivery dates, and terms of the purchase.
Receiving ReportA document prepared by the receiving department upon the arrival of goods, detailing the quantity, condition, and specifications of the items received.
Electronic Data Interchange (EDI)A technology that enables the computer-to-computer exchange of business documents, such as purchase orders, directly between different companies without human intervention.
Fixed Asset SystemA subsystem that manages the acquisition, maintenance, depreciation, and disposal of long-term physical assets used in business operations for more than one year.
Payroll Processing SystemA specialized system designed to calculate employee earnings, manage tax and benefit withholdings, and maintain cumulative earnings records.
Bill-of-Materials (BOM)A comprehensive document that specifies the exact types and quantities of raw materials, sub-assemblies, and parts required to produce a single batch of a product.
Route SheetA document that outlines the specific sequence of manufacturing operations, work centers, and times required to produce a product during the conversion cycle.
Trial BalanceA report prepared at the end of an accounting period that lists the balances of all general ledger accounts to verify that total debits equal total credits.
Finance Information System (FIS)An information system that assists managers in making decisions regarding the acquisition, allocation, control, and analysis of financial resources.
Capital BudgetingThe process of planning, evaluating, and selecting long-term investment projects and capital expenditures that a business intends to undertake.
Cash ManagementThe optimization of a company's cash and cash equivalents to ensure sufficient liquidity for daily operations while avoiding the inefficiencies of holding excess cash.

The Uniform Accounting System in Turkey

In Turkish accounting practices, credit sales without a note are recorded under the Accounts Receivables account, while credit sales backed by a note are recorded under the Notes Receivables account, both structured under the Uniform Chart of Accounts.

Automated Purchasing via EDI

Electronic Data Interchange (EDI) allows businesses to automate purchasing. When inventory reaches a pre-defined critical level, the system automatically transmits a purchase order to the vendor's computer without human intervention.

Three-Way Match Control

To authorize a vendor payment, the accounts payable department performs a three-way match, comparing the Purchase Order, the Receiving Report, and the Vendor Invoice to ensure the business only pays for what was ordered and received.

Useful Life vs. Economic Life

The useful life of a fixed asset is the period the business intends to use it, which may differ from its economic life. For example, a machine with a 10-year manufacturer-specified economic life may have a useful life of only 5 years for a specific business.

Payroll System Separation

Boockholdt (1999) highlights that payroll is processed separately from standard purchases because it requires complex tax withholdings, cumulative earnings reporting, and specialized controls to prevent fraud.

Time Cards and Job Tickets

The payroll process relies on time cards (which record total hours worked for payroll calculation) and job tickets (which allocate labor hours to specific production jobs in the Work-in-Progress ledger).

Batch Production Control Documents

In batch production, the system generates three critical control documents: the work order (authorizing production), move tickets (tracking movement between work centers), and material requisitions (authorizing storekeepers to release materials).

Variance Analysis in Cost Accounting

The cost accounting system compares actual costs against standard costs to calculate variances. These include material price/quantity variances, labor time/wage variances, and manufacturing overhead volume/capacity/efficiency variances.

The Fiscal Year Cycle

The standard fiscal year for businesses begins on January 1st and ends on December 31st. Daily transaction recording and monthly trial balances are performed continuously throughout this period.

Unadjusted vs. Adjusted Trial Balance

The trial balance prepared on December 31st before year-end adjustments is the unadjusted trial balance. After recording depreciation, accruals, and cost of goods sold, the adjusted trial balance is prepared to generate financial statements.

Motivations for Holding Cash

According to Berk and DeMarzo (2007), businesses have three primary motivations for holding cash: to meet day-to-day transaction needs, to compensate for cash flow uncertainty, and to satisfy bank requirements.

Sınavda Dikkat Et

  • Pay close attention to the triggering event of each cycle; for example, the revenue cycle is triggered by receiving a customer order.
  • Do not confuse 'useful life' with 'economic life' of a fixed asset; useful life is business-specific, while economic life is manufacturer-defined.
  • Remember the three-way match documents (Purchase Order, Receiving Report, Invoice) as they are a classic exam topic for internal control.
  • Understand the difference between time cards (total hours for payroll) and job tickets (labor allocation for cost accounting).
  • Note that the unadjusted trial balance is prepared on December 31st before adjusting entries, while the adjusted trial balance provides the final balances.
  • Differentiate between AIS (focuses on recording past financial transactions) and FIS (focuses on future planning, cash management, and capital budgeting).
