Why is deferred billing sometimes called the same as cash?

Deferred billing is defined as one of the technique of sales promotion where organization offers a grace period before the time when the actual payment is made, which consists of an interest-free time if particular payment is done at the certain (defined) date. It is mostly used for the auto and furniture purchases. It is sometimes termed as cash because customers are not invoiced only for certain period of time, after that time, payment has to be made by the customers and they are definitely invoiced and the cash is realized by the company.

a myth is something that is told for many years that u go looking for and cant find and a truth is something that u can find in real life and can be story's of for example:

mermaid's and unicorns: u can't find them at all so they can be a myth cause u hear story's about them once u go looking for them u won't find them.

dinassours(can't spell): u hear story's about them at school by ur friends and one day ur dad takes u to a museum and u find fossils of them so u realize they are real and not fake.

hey kid learn to actually put time and effort into your school work and maybe you would get higher grades and not have to come on this website and beg for answer's
