Difference between bookkeeping vs. e-commerce accounting
- Bookkeepers:
Bookkeepers keep a record of day-by-day financial transactions. They categorize everything and, therefore can track expense and income categories. Some of that information is then entered into reports; manually in the case of bookkeepers using spreadsheets, or automatically through online software. Following are the core functions of bookkeeping for ecommerce business:
- Recording sales from each platform and channel
- Categorising expenses by type
- Reconciling bank accounts and payment processors
- Matching invoices to payments
- Maintaining organised financial records
- E-commerce accounting:
Usually, e-commerce accountants analyze, interpret, and report the finances of a business on a monthly, quarterly, or annual basis. They also file tax returns. Besides, they are supposed to take the information that a bookkeeper has recorded and process it into actionable reports and insight. Following are the core functions of ecommerce accounting:
- Analyse financial data to identify trends and issues
- Prepare financial statements and management reports
- Calculate tax liabilities and identify planning opportunities
- Advise on business structure and tax efficiency
- Ensure compliance with accounting standards and tax regulations
- Provide strategic financial guidance for growth
Types of Accounting for E-commerce Business
- Cash-Based Accounting:
Cash-based accounting is used if your business records revenue at the time of receiving cash and expenses when paid. This method keeps a record of the inflow and outflow of cash through your accounts. It works best with single-entry bookkeeping, but also works well for double-entry bookkeeping too.
- Accrual-based accounting:
If your company recognizes income as it is earned and expenditures as they happen, go with accrual accounting. This approach means you can record the transactions without cash but flowing in or out of your accounts, which allows you to record credit-based sales and purchases the moment they happen. Double-entry bookkeeping is most suitable for accrual-based accounting.
Essential E-commerce Accounting Terms to Know
Here are some essential terms every business owner should understand to start e-commerce accounting.
- Cost of Goods Sold (COGS): Direct costs of producing and selling a product including material, labor, and shipping. Gross profit is determined by subtracting COGS from revenue.
- Gross Profit: Revenue minus COGS. Profit before other expenses, such as marketing and administrative costs.

Faqs:
Do I need an accountant for my e-commerce business?
While not legally required, professional accounting support is highly recommended for e-commerce businesses. The complexity of multi-channel sales, VAT obligations, and platform-specific accounting means errors are common without expert guidance. An accountant can also identify tax savings and provide strategic advice that typically exceeds their fees in value.
How often should I update my e-commerce accounts?
Many successful e-commerce businesses reconcile weekly or even daily during busy periods. Regular updates provide accurate real-time data for decision-making and catch errors early.
When do I need to register for VAT as an e-commerce seller?
You must register for VAT when your taxable turnover exceeds £90,000 in any rolling 12-month period, or if you expect to exceed this threshold in the next 30 days alone. You can also register voluntarily below this threshold, which allows you to reclaim VAT on purchases.
What expenses can I claim for my e-commerce business?
You can claim expenses that are wholly and exclusively for business purposes, including product costs, platform fees, advertising, shipping, software subscriptions, office costs, professional fees, and equipment. Keep receipts and records for all expenses claimed.
