Perparcel

Perparcel is a pricing model in the parcel shipping and logistics sector in which charges are assessed on a per-parcel basis rather than primarily by weight or dimensional weight. In its simplest form, each parcel incurs a fixed base rate, with potential adjustments for destination, service level, or handling requirements. The model is used by carriers and e-commerce logistics platforms as an alternative to weight-based or dimensional-weight pricing, sometimes in combination with zone-based surcharges.

Perparcel emerged as e-commerce growth increased the frequency of small, uniform shipments, creating demand for simpler and more predictable pricing. It is commonly offered as part of a tiered or blended rate card, and may apply in domestic or cross-border shipments. Some implementations separate base per-parcel fees from additional services such as insurance, signature release, or pickup options.

Advantages include pricing predictability, ease of budgeting, and straightforward rate cards that can reduce disputes for merchants dealing with many small orders. It can be appealing for sellers with high volumes of small items and for marketplaces seeking uniform shipping experiences. Disadvantages include reduced sensitivity to weight or size, potentially higher costs for heavier items, and the need for careful policy design to avoid over- or undercharging. Complexity can arise if per-parcel charges are combined with multiple zones or service levels.

Implementation considerations include defining the base rate, defining add-ons, setting service levels, determining destination zones, coordinating with warehouse operations, and ensuring compatibility with storefront and carrier systems. Related concepts include flat-rate shipping, dimensional weight, and zone-based pricing.
