Invoice Line Items
Invoice Line Items
Invoice Line Items represent individual charges on a carrier invoice. Each line item is one charge — not one shipment and not one invoice. A single shipment typically produces multiple line items (for example, a base freight charge, a fuel surcharge, and a residential delivery surcharge would be three separate line items).
Invoice formats vary by carrier — UPS, FedEx, USPS, DHL, DPD, and Royal Mail each structure their invoices differently, and some carriers’ shapes vary further by billing region. Trackstar parses each carrier’s native format into a unified line-item schema described below. For concrete CSV shapes per integration, see Carrier Sample Files.
