Choosing a shipping carrier often affects customer satisfaction more than the product itself, because delivery is the last experience of the purchase and is judged as part of the retailer's service. It is worth comparing pricing by weight and dimensions, the availability of pickup points and parcel lockers, the option to choose a delivery time, the quality of shipment tracking, and above all how damage and losses are handled. A practical measure is to offer at least two options, since customers have established preferences and a single option is often a reason for cart abandonment. Volume plays a role in price negotiations, so smaller e-shops benefit from using shipping aggregators. The share of damaged and undelivered shipments should be tracked by carrier. These figures are precisely the best argument when renegotiating terms or deciding to change partner.
