To satisfy the internal control for sales, all three documents (order, shipping, and billing) need to be presented to ensure that the goods were correctly shipped and billed to the appropriate customer. Simply preparing billing documents (B) or ordering goods (C) or producing goods (D) do not provide sufficient evidence of proper sales controls.
