Accounting can sometimes feel like a language of its own. Whether you’re a small business owner, sole trader, startup founder, or someone new to bookkeeping, understanding key accounting terms can help you make better financial decisions and stay compliant with Australian tax requirements.
This guide breaks down some of the most common accounting and bookkeeping terms in simple, easy-to-understand language.

Why understanding accounting terms matters

Knowing basic accounting terminology helps you:
✅ Manage your business finances with confidence
✅ Understand reports from your bookkeeper or accountant
✅ Meet ATO compliance requirements
✅ Improve cash flow management
✅ Make informed business decisions
Let’s explore the essential terms every business owner should know.

GST (Goods and Services Tax)

GST stands for Goods and Services Tax, a 10% tax added to most goods and services sold in Australia.
Example:
If you sell a product for $110, the GST component is $10, and the remaining $100 is your revenue.

Why GST matters

📌 Businesses registered for GST must:
• Charge GST on eligible sales
• Collect GST from customers
• Claim GST credits on eligible business purchases
• Report GST through their BAS

GST registration

Generally, you must register for GST if your business turnover is $75,000 or more per year.

BAS (Business Activity Statement)

A Business Activity Statement (BAS) is a report submitted to the Australian Taxation Office (ATO).
It helps businesses report and pay:
📋 GST collected and paid
📋 PAYG withholding
📋 PAYG instalments
📋 Other tax obligations

How often is BAS lodged?

Businesses may lodge BAS:
• Monthly
• Quarterly
• Annually (in some cases)

Why it’s important

Missing BAS deadlines can result in penalties and interest charges, which is why accurate bookkeeping is essential.

Cash flow

Cash flow refers to the money moving in and out of your business.
😊 Positive cash flow = More money comes in than goes out.
⚠️Negative cash flow = More money goes out than comes in.

Common cash inflows

💰 Customer payments
💰 Loans received
💰 Investment income

Common cash outflows

💸 Supplier payments
💸 Rent and utilities
💸 Wages and salaries
💸 Loan repayments

Why cash flow is critical

Many profitable businesses still experience financial stress due to poor cash flow management. Monitoring your cash flow regularly helps ensure you can pay bills when they fall due.

Accounts receivable

Accounts receivable (AR) is money owed to your business by customers.
Example
📄 You issue an invoice for $2,000.
Until the customer pays, that amount is considered accounts receivable.

Why monitor receivables?

• Improve cash flow
• Reduce overdue invoices
• Support business growth
The faster customers pay, the healthier your cash position becomes.

Accounts payable

Accounts payable (AP) refers to money your business owes suppliers or vendors.
Example
🧾 You receive a supplier invoice due in 30 days.
Until it is paid, it remains in your accounts payable.

Benefits of managing payables

✅ Avoid late payment fees
✅ Maintain supplier relationships
✅ Improve cash flow planning

Profit

Profit is what remains after all business expenses have been deducted from revenue.

Formula
Profit = revenue − expenses

Example
Revenue: $20,000
Expenses: $15,000
🎉 Profit = $5,000
Profit shows whether your business is financially successful over a period of time.

Revenue

Revenue represents the total income generated from your business activities before expenses are deducted.
Example
A consulting business invoices clients $50,000 during a quarter.
📈 Revenue = $50,000
Revenue is often called:
• Sales
• Turnover
• Income

Expenses

Expenses are the costs incurred to operate your business.

Common business expenses

🏢 Rent
💻 Software subscriptions
📞 Phone and internet
🚗 Vehicle expenses
👩‍💼 Employee wages
📢 Marketing costs
Tracking expenses accurately helps reduce errors and maximise eligible tax deductions.

Reconciliation

Bank reconciliation is the process of matching your accounting records with your bank statements.

Why reconcile?

🔍 Detect missing transactions
🔍 Identify errors
🔍 Prevent fraud
🔍 Ensure accurate financial reports
Regular reconciliation is one of the most important bookkeeping tasks.

Payroll

Payroll refers to the process of paying employees and managing employment-related obligations.
Payroll typically includes:
👨‍💼 Wages and salaries
🏦 Superannuation contributions
📝 PAYG withholding
🎁 Leave entitlements
Accurate payroll ensures compliance and keeps employees paid correctly and on time.

Superannuation

Superannuation (Super) is money employers contribute towards an employee’s retirement savings.

Key points

✅ Mandatory for eligible employees
✅ Requires regular employer contributions
✅ Must be paid by due dates
Failure to meet super obligations can result in penalties.

PAYG withholding

PAYG (Pay As You Go) withholding is money withheld from employee wages and sent to the ATO on their behalf.

Purpose

📌 Helps employees meet their annual income tax obligations.
Employers are responsible for calculating, withholding, reporting and remitting PAYG amounts correctly.

Chart of accounts

A Chart of accounts is a structured list of all financial accounts used within a business.
Examples include:
📂 Income
📂 Expenses
📂 Assets
📂 Liabilities
📂 Equity
A well-organised chart of accounts makes financial reporting much easier.

Assets

Assets are items of value owned by the business.
Examples
🏦 Cash in the bank
🚗 Vehicles
💻 Computers
🏢 Property
📦 Inventory
Assets help generate future economic benefits for the business.

Liabilities

Liabilities are debts or obligations owed by the business.
Examples
💳 Business loans
📄 Credit card balances
🏦 Lease obligations
🧾 Outstanding supplier invoices
Understanding liabilities helps assess the financial health of a business.

Equity

Equity represents the owner’s share of the business after liabilities are deducted from assets.

Formula
Equity = assets − liabilities

Equity shows the overall value belonging to business owners.

Understanding basic accounting terms doesn’t require a finance degree. By becoming familiar with concepts such as GST, BAS, cash flow, accounts receivable, payroll and reconciliation, business owners can make smarter financial decisions and maintain stronger control over their operations.
