A Billing Cycle is the interval of time from the end of one billing statement date to the next billing statement date for goods or services a company provides to another company or consumer on a recurring basis. Although billing cycles are most often set on a monthly basis, they can vary in length depending on the type of product or service rendered.For example, a credit card company may have a billing cycle of 21-25 days, while a utility company may have a billing cycle of 30 days. Billing cycles are important to understand because they can impact when you will receive your bill and when payments are due.If you're a business, it's also important to understand your customers' billing cycles so that you can align your invoicing and payments. This can help you avoid issues with cash flow and keep your business running smoothly.
