Amazon is a particularly interesting example for understanding the difference between net income and the cash a company generates from its activities.
For many years, Amazon reported relatively low net profit margins, even as its revenue and business activity continued to grow. However, when we analyze the statement of cash flows, we often see a different picture: net cash flow from operating activities is much higher than reported net income.
Why does this happen? To understand it, we need to examine how Amazon's business works and how transactions are recorded in its financial statements.
Why is there a difference between net income and operating cash flow?
Three main factors help explain this difference.
First, depreciation and amortization. Amazon has invested large amounts in warehouses, fulfillment centers, transportation equipment, servers, and data centers. These assets are used for several years, and their cost is allocated to the relevant periods through depreciation and amortization.
These expenses reduce net income but do not involve a cash outflow at the time they are recognized as expenses. Therefore, when the statement of cash flows is prepared using the indirect method, they are added back to net income.
Second, employee stock-based compensation. Like many other technology companies, Amazon also rewards some employees with company shares.
This compensation is recorded as an expense in the income statement, reducing net income. However, it usually does not require an immediate cash payment. For this reason, this expense is also added back to net income when calculating operating cash flow using the indirect method.
Third, working capital management and the cash conversion cycle.
This is one of the most interesting aspects of Amazon's business model.
How does Amazon generate cash through the way its business operates?
Think of a typical purchase on Amazon.
A customer orders and pays for a product. The company may collect the payment within a relatively short time, while paying the supplier later, according to the terms of their agreement.
At the same time, Amazon strives to manage its inventories efficiently so that products do not remain unsold for long.
These three elements – the time taken to collect payments from customers, the time products remain in inventory, and the time taken to pay suppliers – affect the cash conversion cycle (Cash Conversion Cycle – CCC).
When this cycle is negative, the company can collect cash from sales before paying the corresponding suppliers. This allows it to finance part of its activities through its payment terms with suppliers.
However, this effect is not the same across all of Amazon's activities and may change from year to year.
