We will need a lot more detail in order to help

@erictgrubaugh Our business module has a subscription of product. When user enroll/register to our app. We create a customer record. Step 2 when user enter the card details we save it under sublist card details. After that we create a cash sale and sale order. Know for transaction we need to create a membership to charge the user according to the billing cycle of the product. How to implement such business model in Netsuite do you have any idea?
