In this blog, we’re diving deep into the most frequent mistakes made in ecommerce income statements and handing you actionable tips on how to sidestep these missteps. 

Let’s get started on turning those financial fumbles into triumphs!

What Is an Income Statement?

What Is an Income Statement?

The income statement provides valuable insights into a company’s revenue, expenses, and net profit or loss during a specific time period. Also known as a profit and loss (P&L) statement, it is one of the three main financial statements used to show whether a business is making or losing money. 

An income statement typically covers a period of one year but can also be prepared monthly, quarterly, or semi-annually, depending on the business’s needs. It consists of several components, such as revenue or sales, which represent all incoming cash from the sale of goods or services before any deductions for expenses. 

Next comes the cost of goods sold (COGS), which represents all direct costs associated with producing or purchasing products for sale. These include materials, labor, and overhead costs directly related to production. Subtracting COGS from revenue gives you gross profit.

Operating expenses come next and include all expenditures necessary to run your business’s day-to-day operations. You can subtract gross profit from operating profit (EBIT).

After operating profit comes non-operating items such as interest income/expense and gains/losses from investments. These are not directly related to regular operations but still impact overall profitability.

Finally comes net income/loss, which is calculated by subtracting taxes from EBIT + non-operating items. This allows you to clearly see where your money is coming from and where it is going. 

By examining trends and changes in these numbers over time, you can gain valuable insights into your business’s financial health and make informed decisions accordingly.

10 Most Common Mistakes in Ecommerce Income Statements 

10 Most Common Mistakes in Ecommerce Income Statements 

❌ Forgetting to Record All Income Sources

One of the most common mistakes made in ecommerce income statements is forgetting to record all sources of income. 

Ecommerce businesses often have multiple revenue streams, including sales from their website, marketplace sales (such as Amazon or eBay), subscription services, and affiliate marketing. 

All of these sources need to be accurately recorded and included in the income statement to calculate your profits and taxable income.

❌ Misclassifying Expenses

Misclassifying expenses can happen when an expense is recorded in the wrong category or when an expense is accidentally left out altogether. 

It’s important to carefully review all expenses and ensure they are accurately categorized in the income statement to ensure you haven’t missed out on any eligible tax deductions or credits.

❌ Not Accounting for Cost of Goods Sold (COGS)

COGS refers to the direct costs associated with creating and selling a product. This includes the cost of materials, labor, and any other expenses directly related to producing the product. 

Not accounting for COGS can significantly impact the accuracy of an income statement, as it directly affects the calculation of gross profit.

❌ Failing to Account for Refunds and Discounts 

While sales returns, refunds, and discounts are all standard in ecommerce, failure to account for these expenses can result in an inaccurate income statement. 

It’s essential to include them as a revenue deduction to accurately reflect the true amount of sales and profits.

❌ Mixing Personal and Business Finances 

Many small ecommerce businesses may combine personal and business finances, which can make it challenging to track and record transactions. 

For example, if you have paid for business expenses using your personal credit card or vice versa, this can become a headache for bookkeepers during record-keeping or auditing.

By keeping your personal and business finances separate with your business bank account, you can avoid errors in the income statement.

❌ Overlooking Depreciation and Amortization

Depreciation and amortization refer to the decrease in the value of assets and intangible assets over time. 

These expenses are often overlooked but can significantly impact the accuracy of an income statement since they must be included as expenses when calculating net profit.

❌ Inconsistent Reporting Periods

❌ Inconsistent Reporting Periods

An income statement should cover a specific reporting period, such as a quarter or year, to show how much you are making and help you prepare for tax season. 

However, an inconsistency in income statements can make it difficult to compare financial performance and calculate tax obligations.

For accurate comparison and analysis, it’s essential to consistently use the same period when creating income statements.

❌ Relying on Manual Calculations  

Manual calculations can be prone to human error, leading to inaccurate entries in income statements and miscalculated figures. 

We recommend using bookkeeping and accounting software or tools to automate these calculations and reduce the risk of errors.

❌ Not Reconciling with Bank Statements 

To ensure the accuracy of an income statement, it should be regularly reconciled with bank statements. 

This helps identify any discrepancies and ensures that all transactions have been accurately recorded.

❌ Neglecting to Update Regularly

Ecommerce income statements should be updated regularly to reflect the most current financial information. 

Neglecting to update income statements can lead to outdated and inaccurate information, making it difficult to make informed business decisions.

How to Avoid These Mistakes: Best Practices for Accurate Ecommerce Income Statements

How to Avoid These Mistakes: Best Practices for Accurate Ecommerce Income Statements

Accurate income statements are essential for any ecommerce business. However, there are common mistakes that can be made when preparing these statements.

To ensure the accuracy of your ecommerce income statement, it is crucial to understand best practices that can help you create accurate ecommerce income statements.

1. Keep Track of All Revenue Streams

Since ecommerce businesses often have multiple sources of revenue, make sure to keep track of all revenue streams throughout the reporting period. 

We recommend having an automated bookkeeping system in place to track all revenue streams, including online sales, physical store sales, and any other sources of income. 

This can be done through accounting software that automatically records each sale and reconciles this data with bank statements, which can help ensure that no revenue is missed.

2. Separate Operating Expenses from One-Time Expenses

While both types of expenses can affect a business’s overall profitability, they should be recorded separately, or they can lead to inaccuracies in calculating net profits.

To avoid this error, clearly differentiate between operating and one-time expenses when recording them on your income statement.

3. Separate Mixing Personal and Business Expenses

While it can be tempting to mix personal and business expenses, this can cause significant errors in your income statement.

To avoid this mistake, strictly separate personal and business expenses by opening a business bank account with a dedicated credit card to manage business expenses. 

Also, keep detailed records of all business-related transactions and only include them on your income statement.

4. Reconcile Your Income Statement with Other Financial Documents

A crucial best practice for accurate ecommerce income statements is reconciling them with other financial documents, such as bank statements or sales reports from different platforms. 

This process involves comparing the data on your income statement with data from these sources to ensure they match. 

If you find any discrepancies, make sure they are investigated and corrected before finalizing your income statement.
