MCF (Multi-Channel Fulfilment)

Amazon & D2C glossary · Harpy Media

MCF (Multi-Channel Fulfilment) lets you use Amazon’s fulfilment network to store and ship products sold on your own channels — your website, Shopify, eBay, a wholesale portal — not just orders placed on Amazon itself.

What is MCF?

You send stock into Amazon’s warehouses once, and it serves every channel. Your DTC order is picked, packed, and shipped by Amazon in unbranded packaging with tracking pushed back to your storefront at a flat per-unit fee. One inventory pool, several income streams, no second warehouse.

Why MCF matters for scaling brands

Relying on a single channel is a concentration risk: when that channel’s demand dips, so does the whole business. Diversifying is the standard answer, but multiple sales channels traditionally mean multiple supply chains — separate warehouses, separate stock, duplicated overhead eating the margin that the diversification was supposed to protect.

MCF resolves that friction by treating the FBA network as your logistics engine for everything. Stock consolidation raises sell-through across the pool (which itself helps storage allowances), capital stops being fragmented across isolated stockpiles, and adding a channel becomes a software integration rather than a supply-chain project.

What MCF costs, and how it behaves

Pricing is per unit, based on size tier and the speed tier chosen — standard, expedited, or next-day. The variables to manage are pack size (larger, heavier units cost disproportionately more) and speed (next-day shipping carries a premium the sale may not justify). Choosing the tier per channel rather than by habit is where the money is.

Operationally, two disciplines matter: stock synchronisation, so the pool never oversells on a channel Amazon does not see, and packaging expectations, because MCF ships unbranded. For brands building a DTC experience, that trade-off — Amazon’s logistics reach against your branded unboxing — is a deliberate choice, not a detail.

In practice

A brand sells a $45 product through its Shopify storefront. Automated API inventory tracking keeps stock counts synced with Amazon’s network in real time. A customer picks standard three-day delivery; the storefront passes the order to Amazon automatically; the item ships in an unbranded box with valid tracking uploaded back to Shopify — for a flat $6.25. The brand collects a predictable profit without touching a cardboard box.

⚠️ Watch out. A competing vendor handles multi-channel orders by hand from a spreadsheet. An order lands on a Friday evening; nobody logs into Seller Central to create the MCF order until Monday morning. The delay misses the carrier cutoff, the package arrives four days late, the customer disputes it, and the external marketplace penalises the storefront’s delivery rating. The failure was administrative, and the cost was channel reputation.

💡 Harpy tip. Automate the bridge before you scale the channel: real-time stock sync, automatic order forwarding, and a defined cutoff schedule. Then choose speed tiers per channel deliberately — fast where speed sells the sale, standard where it does not. Manual multi-channel handling works right up until the first busy week.

How Harpy Media helps

Multi-channel logistics is part of the operations work we run with brands — deciding when MCF beats a 3PL, wiring the stock sync so oversells cannot happen, and pricing shipping tiers against each channel’s actual delivery expectations.

MCF FAQ

Can MCF ship orders from any website?

Yes — MCF works with orders from your own site, marketplaces, and other channels. You submit the order to Amazon with the shipping details, and Amazon handles pick, pack, and dispatch in unbranded packaging.

Is MCF more expensive than FBA?

MCF generally costs more per unit than FBA because it does not require the sale to be on Amazon — there is no marketplace referral revenue sharing the cost. Compare the MCF fee against your own fulfilment cost (warehouse, labour, packaging, carrier rates) rather than against FBA.

Does MCF affect my Amazon account health?

It uses the same inventory pool, so good MCF sell-through supports the inventory metrics that govern storage allowances. Dispatch performance for MCF orders is measured relative to the speed tier you selected, which is why tier choice per channel matters.
