Concept:A sale where goods or services are delivered now but payment is postponed.
Explanation:In this arrangement, the seller transfers ownership of goods or services to the buyer immediately.
The buyer does not pay the full value at that moment.

This is known as a credit sale, because the seller gives credit to the buyer.
It is different from hire purchase (ownership transfers after installments), leasing (rental with no ownership), or mutual understanding (not a formal trade term).
