Customer-Initiated Installment Payments with PAN

An installment payment is a single purchase of goods or services billed to a customer in multiple transactions over a period of time agreed to by you and the customer, and sometimes, the issuing bank. The agreement enables you to charge a specific amount at specified intervals. For customers, installment payments provide greater purchasing power and lower impact on their monthly budget. For you, offering installment payments at checkout can help increase the number of successfully completed purchases.
Before you can accept installment payments, you and your acquirer must agree on the maximum number of installments you can accept, which can be different for each card type.
