Amazon Multi-Channel Fulfillment (MCF): A Practical Setup Guide

Once you've decided that Amazon should fulfill your direct orders, the next question is purely practical: how do you actually wire it up? Multi-Channel Fulfillment (MCF) lets Amazon store, pick, pack, and ship orders that come from your website using the same inventory pool that serves the marketplace. Setting it up is less about logistics and more about getting four things right.

Before you start: is MCF the right call?

If you're still weighing the model itself, read FBA vs. MCF first — it covers when each makes sense. The short version: MCF earns its keep when you're building a direct-to-consumer brand, want one inventory pool across channels, and would rather not run a warehouse. New to Amazon's network entirely? Start with how fulfillment actually works.

The four-step setup

1. Connect your store to MCF

MCF can be driven directly from Seller Central or through an integration that connects your storefront to Amazon's fulfillment API. If your platform has an official app or plugin, that's usually the lowest- friction path: orders flow to Amazon automatically instead of you keying them in by hand.

2. Send in inventory and pool it

Create a fulfillment shipment and send units into Amazon's network. The point of MCF is a single pool — the same units can fill an Amazon sale or a sale on your site, so you're not splitting stock and guessing which channel needs it. Keep a buffer so a sudden spike on one channel doesn't strand the other.

3. Map your SKUs carefully

This is where most setups go wrong. Every product on your website needs to map to the exact Amazon SKU it draws down from. A mismatch here means you either oversell stock you don't have or hide stock you do. Double-check the mapping before you go live, especially for bundles and multi-packs.

4. Route orders and pick a speed

With everything connected, incoming website orders route to Amazon for fulfillment. You'll choose a delivery speed (standard or expedited) and a packaging option. Standard MCF boxes are Amazon-branded unless you opt into blank or branded packaging, which can carry an extra fee — worth it if unboxing is part of your brand.

Don't skip the economics

MCF's convenience has a per-unit cost, and at low volumes it can be pricier than shipping yourself. Model it before you commit: run your product through the FBA & MCF profit calculator so you know your true landed cost and margin on every channel. If the numbers work, MCF buys you something valuable — Amazon's speed and reliability on orders you fully own.

How we run it

At Novus Supply we fulfill both our Amazon and direct orders from one pool, so a customer on our own site gets the same fast delivery as a marketplace shopper. Get the four steps above right — connect, pool, map, route — and MCF mostly disappears into the background, which is exactly what good fulfillment should do.
