A Complete Guide To E-commerce Accounting


The Australian e-commerce market is both vibrant and fast-growing, with an expected revenue of USD 37 billion in 2023. It is the 14th largest market in Australia comprising businesses such as:

  • Clothing (43%)
  • Shoes (31%)
  • Books, movies, music, and games, excluding downloads (24%)
  • Cosmetics and body care (22%)
  • F & B excluding restaurant deliveries (22%)

Australians love online shopping. They spent AUD 52.7 billion in 2022. However, there is still scope for growth as this value only represents 12.6% of the total retail market.

If you are a solopreneur who is considering expanding your e-commerce business, this guide is for you! 

Before we delve deeper, here is a quick walkthrough of e-commerce accounting. 

Definition of, and Need for E-commerce Accounting

An e-commerce business is defined as the trading of goods and services over the Internet. Though it looks fairly simple on the outside, e-commerce accounting does require close tracking of financial transactions, purchase and sales orders, e-commerce sales tax, and cost of goods sold. Managing all of this while working on your store can be tedious. But, services like Sleek can help!  

Australia has over 83,000 online shopping businesses as of 2023  , an increase of 14% from 2022. The current size of Australian e-commerce businesses and the expected growth over the next few years (market volume of US$53.3 billion by 2027  ) show the strong need for specialised services offering e-commerce accounting, and professional organisations such as Sleek  that can offer tailored solutions to every kind of e-commerce business. 

Differences Between E-commerce Accounting Services & Traditional Bookkeeping

E-commerce accounting and Traditional Bookkeeping have distinct differences due to the nature of the businesses they support. 

An e-commerce business requires you to manage several financial considerations and challenges, such as payments, customer returns, shipping logistics, and inventory management. 

Transaction Volume

  • E-commerce Accounting: An e-commerce seller typically handles a higher volume of transactions compared to traditional brick-and-mortar stores. This requires efficient tracking and management.
  • Traditional Bookkeeping: Traditional businesses generally have lower transaction volumes. This makes it easier to manually record and manage financial data.

Source of Transactions

  • E-commerce Accounting: An e-commerce store operates from multiple digital sales channels, which involve digital payment methods and electronic invoices.
  • Traditional Bookkeeping: Traditional businesses conduct transactions on one sales channel with basic bookkeeping tasks such as managing cash, checks, or other non-electronic payment methods.

Data Collection and Integration

  • E-commerce Accounting: It involves integrating data from various digital platforms. Most e-commerce companies today use cloud accounting services such as Sleek to streamline and simplify operations.
  • Traditional Bookkeeping: It relies more on manual financial data entry from physical documents, such as receipts, invoices, and ledgers.

Inventory Management

  • E-commerce Accounting: Business owners have to handle real-time inventory management which is closely tied to accounting systems to ensure accurate financial reporting on the company’s financial position.
  • Traditional Bookkeeping: Traditional businesses with physical stores also manage inventory, but it is less dependent on real-time tracking to track sales.

Multi-Currency Transactions

  • E-commerce Accounting: To ensure their business grows quickly, entrepreneurs may have to engage in cross-border sales and international transactions, involving multiple currencies. Handling profit margins, currency conversions and exchange rate fluctuations is therefore crucial.
  • Traditional Bookkeeping: Traditional businesses usually deal with transactions in a single currency. 

Customer Feedback & Interactions

  • E-commerce Accounting: The success of an online business is influenced by customer reviews, feedback, and online interactions. Timely responses to customer feedback become more important as the business grows.
  • Traditional Bookkeeping: Traditional bookkeeping focuses less on customer interactions and more on managing a positive cash flow.

Technology Integration

  • E-commerce Accounting: It heavily relies on cloud-based accounting software and online tools for managing accounting tasks such as accounts payable and cash flow statements.
  • Traditional Bookkeeping: It relies mainly on an accounting method that uses physical records and manual systems. 

To summarise the key differences:

Different Accounting Approaches for E-commerce

In Australia, accounting firms can use various accounting approaches to manage the finances of e-commerce businesses:

  • Accrual Accounting: Revenues and expenses are recognised when they are earned or incurred
  • Cash Basis Accounting: Revenues and expenses are recorded only when cash is received or paid
  • Hybrid Accounting: A combination of accrual and cash basis accounting
  • Inventory Accounting Methods: First-in-First-Out (FIFO) and Last-in-First-Out (LIFO), which can impact the cost of goods sold (COGS) and tax planning
  • Goods and Services Tax (GST) Accounting: In Australia, businesses (including e-commerce businesses) with a GST turnover of $75,000 or more must register for GST

Regular Tasks for Best Practice

Like all accounting methods and practices, e-commerce accounting also requires you as an e-commerce entrepreneur to carry out certain tasks regularly for accurate and lawful financial records. You also need to be compliant with rules and regulations governing e-commerce transactions and taxation.

Routine tasks are those that need to be performed as per a set schedule (daily, weekly, monthly or other frequency). They include recording of all sales transactions and expenses, bank reconciliation, tracking foreign currency exchange rates, inventory management, tax return filing and inventory tracking.

Your e-commerce business must develop and adopt best practices followed by other industry players. These include the adoption of up-to-date online accounting software for real-time monitoring, software for automated data entry and reconciliation, integration of payment gateways for ease of transactions and compliance with all mandatory financial and tax obligations.

These practices collectively uphold efficient financial management, compliance, and trustworthy reporting in the dynamic realm of e-commerce.

E-commerce Payment Methods

E-commerce business owners in Australia accept various payment methods. Offering multiple modes of payment to buyers also increases revenue for small businesses. Some of the popular payment modes are:

  • Credit and Debit Cards
  • PayPal
  • Bank Transfers
  • Apple Pay and Google Pay
  • BPay

These are linked to the accounting system and the bank accounts of the e-commerce companies. It is vital that an e-commerce accounting service track all sales and refunds from these sources. 


As a small e-commerce business owner, your choice of e-commerce accounting would depend on various factors. A qualified e-commerce accountant or professional services can help simplify it for you.

Key components of e-commerce accounting are a higher volume of online sales, multiple payment gateways, and global customers. It requires specialised tools to integrate data from various platforms and handle multi-currency transactions, making it more complex than traditional brick-and-mortar businesses.

The best accounting software for an e-commerce business depends on various factors. Popular options for e-commerce sellers include Sleek, a cloud-based e-commerce accounting service that offers several unique features to streamline operations.

Many accounting firms use an inventory accounting system Like FIFO or LIFO to track stock levels and valuations of their sales channel. E-commerce businesses can use specialised inventory management software that integrates with their accounting system to ensure accurate records and avoid overstocking or stockouts.

E-commerce sellers handling multi-currency transactions have to monitor exchange rates and foreign currency gains or losses. These can impact the company's finances and gross profit. Many accounting software solutions offer multi-currency support, allowing businesses to record transactions in their respective currencies and automatically convert them to the base currency for reporting.

An e-commerce store in Australia must comply with relevant tax regulations in its business budget.

In Australia, e-commerce businesses must have a business tax ID number. It must also consider Goods and Services Tax (GST) and income tax requirements.

Businesses must register for GST if their annual turnover exceeds the threshold, charge GST on sales, and claim GST credits on eligible purchases. Income tax obligations involve reporting business profits and expenses in annual tax returns.

It is advisable to consult with a qualified accounting service like Sleek to ensure proper tax compliance and maximise available tax benefits for your e-commerce business.
