Cost of Sales
Cost of Sales (COS) is a key operational metric used in ecommerce to measure the total cost associated with selling a product or service.
Cost of Sales (COS) is an important operational metric used in ecommerce to measure the total cost associated with selling a product or service. It helps to accurately calculate the profitability of a business by subtracting all the associated costs from gross revenues. This includes all cost related to purchasing inventory, maintaining and managing the inventory, additional costs associated with item returns, and more. COS can be calculated on a daily, weekly, monthly, quarterly, and yearly basis, making it an essential metric for understanding the figures that go into running a successful ecommerce business.
Formula
Cost of Sales (COS) = Inventory purchased + Shipping + Packaging + Returns
Example
Let's say that an ecommerce retailer purchases a total of 1,000 items of inventory for $10,000. They pay $3,000 for shipping and packaging and account for a return of 40 items with a sale value of $400. The cost of sales for this transaction would be: $10,000 + $3,000 + $400 = $13,400.
Why is COS important?
Cost of Sales (COS) is a critical metric for ecommerce retailers as it helps to track the overall profitability of their business. COS helps to accurately evaluate the price of goods or services and the associated total cost with returns. This can help retailers to identify and address costly problems before they become major losses.
Which factors impact COS?
Several factors can impact Cost of Sales (COS). The quality of products, shipping costs, packaging costs, inventory turnover rate, and return rates all influence COS. Changes in seasons and fluctuations in market demand can also have an impact on COS.
How can COS be improved?
Retailers can improve their Cost of Sales (COS) through a variety of strategies. This includes optimizing inventory procurement processes, sourcing from competitive suppliers, and negotiating better contract terms. Additionally, retailers can limit returns through better customer service and improving product quality.
What is COS's relationship with other metrics?
The success of any ecommerce business can be evaluated by monitoring multiple metrics. Cost of Sales (COS) is usually seen in relation to Gross Profit Margin, Inventory Turnover Rate, and Return Rate. The higher the COS, the lower the Gross Profit Margin, Inventory Turnover Rate, and Return Rate.
