Easyship
Easyship is a global multi-carrier shipping platform and API aimed at cross-border e-commerce, aggregating rates across dozens of international couriers and postal services to help merchants find the cheapest or fastest option for shipping a given package to a given country, including automatic duty and tax calculation shown to the buyer at checkout (avoiding the surprise import-fee-at-the-door problem that causes abandoned cross-border deliveries).
The API covers rate shopping across connected carriers, label generation, automated customs documentation for international shipments, and a "landed cost" calculator that estimates total cost (shipping + duties + taxes) for a buyer in a specific destination country before they complete checkout — a feature specifically aimed at reducing cart abandonment on international orders. Tracking updates are aggregated into a single format across all supported carriers.
For Nigerian e-commerce merchants selling internationally — exporting Nigerian-made goods, fashion, or crafts to diaspora customers or international buyers — Easyship's landed-cost-at-checkout and customs automation address two of the biggest friction points in cross-border e-commerce from Nigeria: unpredictable delivery costs for the buyer and manual customs paperwork for the seller. For purely domestic Nigerian delivery, Easyship is not the right tool; it's specifically oriented toward international shipment flows.
