What is the difference between working capital cycle, net operating cycle and cash conversion cycle?

Working capital equals corporate short-term assets minus short-term liabilities. In financial terminology, “short term” refers to a time frame of 12 months or fewer. For example, a short-term debt becomes due within 365 days, and cash -- a short-term asset -- will serve in a company’s operations for the next 52 weeks. Working capital is a liquidity indicator that provides a glimpse into how much cash a business will have in its coffers for the next 12 months. When finance people talk about current assets and liabilities, they mean short-term resources and debts.

A company’s cash conversion cycle consists of the operational journey a transaction takes to generate money for the business. It starts with the review and background check of a potential customer, the evaluation of the client’s financial standing and creditworthiness, and the credit approval for a specific transaction or a series of deals. After a company ships merchandise to the patron, accounting managers record the underlying receivable, also known as a customer receivable or account receivable. The corporate cash conversion cycle also goes through the receipt of customer funds as well the collection and recovery efforts -- when it comes to customers’ default, near insolvency or bankruptcy.

Cash conversion cycle and  net operating cycle are the same.
