Top 5 E-commerce Accounting Mistakes: Are You Making Them?

If you are a business owner who has ventured into the e-commerce world, you are likely well aware of the unique challenges of managing your online store’s finances. While e-commerce accounting may seem straightforward at first glance, several common mistakes can turn this simple task into a complex headache.

This article will highlight the top e-commerce accounting mistakes you might be making.

1. Neglecting to Track All Expenses

One of the most common mistakes e-commerce business owners make is failing to track all expenses related to their business. These expenses may include anything from shipping costs to advertising fees and even the products' price.

Often, business owners will only track the most obvious expenses, such as the cost of inventory, while neglecting to account for other, less obvious costs. This can lead to inaccurate financial reports and potentially result in the business owner paying more taxes than necessary. Therefore, keeping a detailed record of all expenses is essential to have a clear picture of your business’s profitability.

2. Not Using the Right Accounting Software

Another common mistake is to use the right accounting software for your e-commerce business. Many business owners will try to handle their finances using essential spreadsheet software, but this can quickly become overwhelming as your business grows.

Many different accounting software options are available today, specifically for e-commerce businesses. These software applications can help you manage your inventory, track your expenses, and even automate your tax calculations, making your e-commerce accounting tasks much more accessible.

3. Incorrectly Calculating Sales Tax

Sales tax can be tricky in e-commerce accounting, especially for businesses that sell products in multiple states or countries. Each jurisdiction has its rules and rates for sales tax, which can change frequently. Many e-commerce business owners need to stay up-to-date with these changes, which can result in undercharging or overcharging their customers for sales tax.

To avoid this, it is vital to use an e-commerce platform that automatically calculates sales tax based on the customer’s location.

4. Not Reconciling Bank Statements Regularly

Reconciling your bank statements with your accounting records is fundamental to managing your e-commerce business’s finances. However, many business owners neglect this task because they find it tedious or simply forget to do it.

Failing to reconcile your bank statements can lead to discrepancies in your financial records, making it difficult to assess your business’s financial health accurately. Therefore, making bank reconciliation a regular part of your e-commerce accounting routine is crucial.

5. Mixing Personal and Business Finances

Finally, one of the biggest things e-commerce business owners must correct is mixing their personal and business finances. This can make it incredibly difficult to keep track of your business expenses and lead to several complications come tax time.

To avoid this, it is recommended to have separate bank accounts for your personal and business finances. This will make it much easier to manage your e-commerce accounting and help ensure that your financial records are accurate and up-to-date.


Managing your e-commerce business’s finances can be a complex task, but avoiding these mistakes can help ensure that your accounting is accurate and efficient. Remember to track all expenses, use the right accounting software, stay up-to-date with sales tax changes, reconcile your bank statements regularly, and keep your personal and business finances separate. Doing so can help set your e-commerce business up for financial success.
