Introduction

Running an online store isn’t just about selling cool gear. It’s about how fast and smoothly you can get packages from your shelf to the shopper’s door. Customers now expect Amazon Prime speed, even if they’re buying from Walmart Marketplace, Etsy, or a small Shopify shop.

That’s where fulfillment comes in. Models like Amazon FBA, FBM, third-party logistics (3PL), and prep centers are the engines of eCommerce. Each one comes with perks and quirks. Some give you speed, some give you control, and others let you scale up without drowning in boxes.

Think of it like cars. You can drive a compact car (FBM), hop in a Tesla with autopilot (FBA), hire a pit crew for racing (3PL), or get a dedicated garage crew to prep your car before each run (prep centers).

This article breaks down these models, lays out best practices, and shows how smart sellers—from Amazon private label brands to Walmart resellers—choose fulfillment to boost sales and cut headaches.
