  title: Intuit Customer Invoice Payment Cycle
  summary: Onboard a customer, invoice them, and record their payment end to end.
  description: >-
    A complete order-to-cash cycle for QuickBooks Online expressed as one
    Arazzo workflow. The flow creates a new Customer, raises an Invoice against
    that customer, and then records a Payment linked back to the invoice so the
    receivable is cleared. It chains the customer Id and invoice Id forward so
    the three entities stay linked. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
