The possible line types for a sale record. One of the possible order line types for a sale is an adjustment. Sales adjustments occur when a refund is issued for a line item that is either more or less than the total value of the line item. Examples are restocking fees and goodwill payments. When this happens, Shopify produces a sales agreement with sale records for each line item that is returned or refunded and an additional sale record for the adjustment (for example, a restocking fee). The sales records for the returned or refunded items represent the reversal of the original line item sale value. The additional adjustment sale record represents the difference between the original total value of all line items that were refunded, and the actual amount refunded.
