Capacity

Carrier

Any entity that physically moves freight or parcels. National parcel carriers (UPS, FedEx, USPS), regional carriers, specialist carriers. Distinct from a 3PL, which manages logistics on top of carrier capacity.

Where this fits

Capacity comes in many shapes. Internal drivers, contracted carriers, gig couriers, autonomous units. Nash treats them as one pool ranked by the rules you set so each order goes to the option that best matches its promise instead of a static default.

Gig courier: An independent driver dispatched per delivery through a marketplace (Uber, Roadie, Senpex, others). On-demand capacity that flexes with demand without taking on payroll.
Vehicles: The physical units a delivery rides in: vans, trucks, e-bikes, motorcycles, drones, autonomous pods.
