  title: Merge Accounting Bill a Customer
  summary: Create a customer contact, raise an invoice against that contact, and confirm the invoice.
  description: >-
    A core accounting write pattern for billing a customer. The workflow
    creates a contact flagged as a customer, raises an invoice of type
    ACCOUNTS_RECEIVABLE against that contact, and then reads the invoice back to
    confirm it was persisted. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
