by

Switching to a 3PL service provider is one of the most important operational decisions an ecommerce brand can make. A strong partner can reduce shipping costs, improve accuracy, and help your brand scale faster, but only if onboarding is smooth, structured, and transparent.

For brands looking at the East Coast, New Castle, Delaware has become a highly strategic fulfillment hub. Its proximity to major metropolitan areas and prime shipping corridors makes onboarding with a New Castle 3PL service provider both efficient and cost-effective.

This guide breaks down exactly what a 3PL service provider does, what the onboarding timeline looks like, what costs to expect, and how to prepare your team for a seamless transition.

What Is a 3PL Service Provider?
