## Introduction

Every business must record, process, and report its financial transactions to operate lawfully, provide information for decision making, and protect its assets. The accounting function is responsible for capturing all business transactions as they occur, ensuring they are properly classified, processed, and recorded in the organisation’s accounts. Effective record keeping relies on clear procedures, supporting documentation, and robust controls to reduce errors and safeguard against fraud. Transaction processing involves multiple key activities, such as handling sales, purchases, payroll, cash receipts and payments, and managing inventory records. All of these activities must be underpinned by strong internal controls.

### The Role of the Accounting Function

Accounting is central to managing a business. The accounting team collects, codes, records, and processes data generated by the organisation's transactions. This provides up-to-date, accurate information for management, shareholders, regulators, and other stakeholders.

### Key activities undertaken by accounting functions

- Recording all transactions as they occur (sales, purchases, receipts, payments, payroll)
- Maintaining orderly records, systems, and filing of supporting documentation
- Ensuring that all income and expenditure are traced and tracked to the correct account codes for reporting and control
- Producing periodic accounts, including the statement of profit or loss, statement of financial position, and statement of cash flows
- Ensuring legal compliance with company law, tax, and reporting requirements
- Implementing and checking financial controls to protect against error and fraud

> **Key Term: transaction processing**
> The step-by-step recording and handling of business transactions through established accounting systems and routines, from initial entry to final reporting.

### Transaction Processing Systems

For reliability and efficiency, most organisations rely on systems and formal routines for managing financial transactions. These systems set out how transactions move from initial occurrence to entry in the accounting records and, ultimately, to financial reporting.

### Core transaction cycles

- Sales (order to cash)
- Purchases (procure to pay)
- Payroll (work done to payment)
- Cash management (banking and petty cash)
- Inventory (stock acquisition, use, and movement)

Each cycle consists of a sequence of steps and generates documentary evidence at each stage. Documentation supports timely and accurate entry into the accounting records.

> **Key Term: documentary evidence**
> Written documents or electronic records (such as invoices, receipts, contracts, timesheets) that support the occurrence and value of a business transaction.

### Record Keeping

Accurate record keeping is essential for:

- Providing evidence of transactions and fulfilment of obligations
- Supporting decisions and analysis
- Satisfying the organisation’s legal, tax, and audit requirements

Records must be clear, maintained in an orderly system, and retained for a period set by law. Proper records are a solid basis for reliable financial statements and support management in controlling operations.

### Main types of accounting records

- Primary documents (invoices, receipts, contracts, timesheets)
- Books of prime entry (journals for cash, sales, purchases, payroll, etc.)
- Ledgers (accounts for assets, liabilities, income, and expenses)
- Supporting schedules (for accruals, prepayments, inventory)
- Registers (fixed asset register, payroll summary, cash book)

> **Key Term: books of prime entry**
> The first set of records where business transactions are initially recorded in chronological order before posting to ledgers.

### Key Financial Systems and Procedures

_Procure-to-pay procedures show document flow from requisition and purchase order to invoice matching, payment authorisation, ledger recording, and reconciliations._

### Sales System

The sales system manages processing of customer orders, despatch, invoicing, and receipt of payment. Key documents include sales orders, delivery notes, sales invoices, and remittance advices.

> **Key Term: sales invoice**
> A document sent by a business to its customer requesting payment for goods or services supplied.

### Purchases System

The purchases system handles ordering goods and services, confirming receipt, processing supplier invoices, and authorising payments. Main documents are purchase requisitions, purchase orders, goods received notes, supplier invoices, and payment records.

### Payroll System

Payroll ensures employees are paid correctly and on time. It requires input of time records, calculation of gross to net pay, deduction of taxes and contributions, and payment to employees and authorities. Payroll records must be confidential and accurate.

### Cash System

Cash systems record all receipts and payments via bank accounts or petty cash. Controls here prevent misappropriation, errors, or unauthorised payments. Bank reconciliations are critical.

### Inventory System

Inventory management tracks the buying, storage, movement, and issuing of goods. Inventory records support decision making on ordering, usage, and valuation.

### Internal Controls in Transaction Processing and Record Keeping

Controls are necessary in accounting systems to ensure completeness, accuracy, and security. They reduce risks of error, theft, or fraud in transaction processing and record keeping.

Typical controls include:

- Segregation of duties (no single person completes every stage of a transaction)
- Document authorisation (signed approval for placing orders and making payments)
- Matching supporting documentation (e.g., matching invoices to orders and receipts before payment)
- Physical safeguards over assets and records
- Independent review and reconciliations (bank, supplier, customer balances)

> **Key Term: internal control**
> The processes and procedures that ensure an organisation’s operations are carried out effectively, its assets are safeguarded, and its financial records are reliable.
> **Key Term: segregation of duties**
> Dividing responsibility for transaction processing between different people to minimise risk of error or fraud.

### Coding and Classification

Accounting systems organise and process extensive amounts of data through coding structures. Each account, department, product, or document may be assigned a unique code, which simplifies data entry, tracking, and analysis.

A well-designed coding system enables easy retrieval, reduces classification errors, and improves consistency across records.

> **Key Term: coding**
> Allocation of an alpha-numeric identifier to accounts, departments, transactions, or items to assist with accurate entry and organisation of accounting records.

### Information Flow and Reporting

After processing, accounting records provide information for management and regulatory reporting. Good record keeping helps prepare periodic management accounts, statutory financial statements, and tax returns. Reports are used by internal and external users to assess performance, plan, and make decisions.

### Importance of Timeliness and Accuracy

All transactions must be recorded promptly and completely. Delays or errors in transaction processing can result in inaccurate reports, missed payments, loss of assets, or regulatory breaches. Prompt and accurate record keeping supports business efficiency and compliance.

### Worked Example 1.1

> **Question:**
> A company places an order for office supplies. What documents and records would be generated through the purchases cycle, and what controls should be in place?
>
> **Answer:**
> Documents produced include a purchase requisition, purchase order, goods received note, and supplier invoice. Accounting records reflect the liability in the purchases journal and ledger. Controls should require authorisation of orders and payment only after matching the purchase order, receipt, and invoice.

### Worked Example 1.2

Why is segregation of duties important in the payroll system?

> **Answer:**
> If one person handles all payroll tasks (input, calculation, payment), errors or fraudulent payments could go unnoticed. Segregating payroll preparation from authorisation and payment reduces the risk of errors and fraudulent payments.
>
> **Exam Warning:**
> Failing to maintain proper records can result in legal penalties, audit qualifications, and loss of management control. Incomplete records or undocumented transactions may not be accepted by tax authorities or auditors.

## Summary

The accounting function structures how transactions are captured, checked, recorded, and reported through financial systems. Effective transaction processing and record keeping systems rely on clear procedures, supporting documentation, consistent coding, and robust internal controls. These help organisations manage performance, meet legal obligations, and protect against error and fraud.
