Inventory management in eCommerce accounting involves tracking and recording product movement within an online business. Starting from the point of purchase, inventory levels are updated in the financial records. This process helps accurately calculate inventory costs, analyze profits, and improve overall operational efficiency.
In this post, we’ll explain why effective inventory management matters so much for eComm accounting, discuss some of the key accounting terms your startup should know (i.e., COGS, turnover, inventory valuation, etc.) and explain how you can master inventory accounting.

Why Inventory Management Matters for eCommerce Accounting
Inventory management for eCommerce accounting is directly tied to your startup’s financial health and its growth. Accurate tracking can help find that perfect balance between understocking and overstocking and help improve profitability. It can also help startups streamline their overall inventory processes to improve operational efficiency and order fulfillment.
Furthermore, the better your inventory data, the clearer the picture you’re likely to have of your startup’s overall financial health. This can help produce more reliable financial statements, tax compliance and better allow leadership to make strategic decisions.
There’s also a direct link between inventory and cash flow. Inventory and cash flow have an inverse relationship. That is, when inventory levels increase, cash flow typically decreases – and vice versa. However, when inventory is sold quickly, it generates revenue and improves cash flow. Inventory management for eComm accounting can help strike that balance with your inventory so your cash flow remains favorable.
Key Inventory Accounting Terms Every eCommerce Startup Should Know
Here’s a look at some inventory accounting terminology that your eComm startup should know:
- COGS: Cost of goods sold (COGS) is the total cost involved in making a product or providing a service. Variables such as raw materials, labor, packaging, production costs, storage, shipping costs and sales commissions are all added to determine the COGS.
- Beginning inventory: Also known as “opening inventory,” this is the total value of a company’s inventory at the very start of the accounting period. It helps your startup gain a clearer understanding of its inventory levels, manage stock efficiently, and make more informed purchasing decisions.
- Ending inventory: Also known as “closing inventory,” this is the value of your startup’s inventory that’s ready to sell at the end of an accounting period. Ending inventory can help your startup better understand its assets, profit and stock levels.
- Inventory turnover: Inventory turnover is the rate at which inventory stock is sold or used, and then replaced. Generally, the higher the ratio, the stronger the sales – and vice versa. You can determine inventory turnover by dividing COGS by the average inventory over a period.
Common Inventory Accounting Methods for eCommerce Startup
There are several different accounting methods that your eComm startup may choose from. Here’s a look at some of the most popular:
- FIFO: The First-In, First-Out inventory accounting method operates under the assumption that the first items that are purchased are the first ones that are also sold. Key benefits of this method include minimizing waste and product loss and it’s ideal for ensuring that perishable goods with expiration dates are used before their shelf life expires. However, the FIFO method often leads to enhanced record-keeping needs and the COGS may not reflect the cost of production during volatile periods. Most eComm startups use this method due to how inventory typically moves within an online store.
- LIFO: The Last-In, First-Out method assumes that the most recent inventory items are sold first. LIFO is an ideal inventory method during high periods of inflation. It’s also commonly used when startups want to reduce their tax liability. An additional benefit and direct result of lowering taxable income is improved cash flow. However, the LIFO method can distort earnings and tends to be a more complex method.
- Weighted Average Costing: This accounting method calculates the average cost of a unit of inventory to determine COGS and overall inventory. It can help simplify accounting, tends to be more accurate than other methods in reflecting current costs and it’s easy to implement.
Best Practices for Inventory Accounting in eCommerce
Selecting the best inventory accounting method for your startup is just the start. It’s also important to follow various best practices to ensure that your inventory accounting is optimized.
For instance, you’ll want to be sure you’re conducting regular audits and integrating accounting software into your inventory tracking so you can have access to accurate data from a central portal in real time. Inventory management software automates these processes, ensuring accurate inventory records and delivering actionable insights to support your startup’s decision-making.
Accurate inventory tracking helps strike that perfect balance between understocking and overstocking, allowing startups to proactively reorder items before they’re depleted and maintain a high level of customer satisfaction.
Tools and Software for Streamlined Inventory Management
While you can manually track your inventory in Excel, more advanced tools are now available to streamline processes and automate certain tasks. Advanced inventory management software like Finale and Cin7 offer features such as real-time updates on stock, reordering alerts, and easy integration with other programs to help streamline and improve inventory management. This latter benefit can help reduce manual data entry and offer startups better overall visibility into their stock levels.
Challenges in eCommerce Inventory Management and How to Overcome Them
Your startup is likely to face various challenges when it comes to managing inventory. Some of these challenges may include:
- Shrinkage: Shrinkage refers to the difference between the recorded stock and the actual stock on hand. When there’s shrinkage, it means that there’s less stock physically available than what the system shows. The best way to avoid this pain point is to ensure you’re conducting regular audits, preventing employee theft and utilizing a robust inventory and supply chain management program. Cycle counting can also help identify inventory discrepancies.
- Obsolete inventory: Obsolete inventory refers to items that you’re stocking that are no longer in demand or have lost significant value. Good demand forecasting, routine audits and performing market trend analysis can help startups overcome this.
- Demand forecasting issues: It’s often challenging to predict customer demand, which can lead to too much or too little inventory. Utilizing the right inventory management tools can help with forecasting based on historical sales data, market trends and seasonal patterns to better forecast demand.
Mastering Inventory Accounting for eCommerce Success
Simply put, inventory management helps support your overall business growth. Good inventory management is often reflected in your startup’s financial records and helps with cost calculation, profit analysis and overall operational efficiency. To ensure that your inventory accounting is optimized, it may make sense to work with a professional.
