As you are telling that “subscription contract” is unrelated to how your merchant’s will be billed nor how you’ll be paid out. Could you tell me what is this and in which cases we need “subscription contract” , which according to the documentation: “Each billing cycle has a start date and end date, and the next billing cycle starts on the day following the previous cycle’s end date. Each billing cycle also has a billingAttemptExpectedDate, which represents the single date in the cycle on which the app is expected to bill the customer for their contract.”
