Companies need to create installment payments for customers and vendors. Users may run into challenges creating installments using out-of-the-box Business Central Payment Terms. The installments need to be added manually to Purchase and Sales Orders. The Installment Payment Terms app will help you easily split payments into installments.
Use the payment term codes with additional installment payment terms on Purchase and Sales Orders/Invoices.
After posting a purchase or sales invoice, the system automatically splits the payment according to the installment payment setup.

- Open the payment terms page and enter a new Payment Term.
- There are two columns added to the Payment Terms table to manage Installment Payments.
