What 3PL actually is — and when a brand needs one

Third-party logistics — 3PL — is the outsourcing of warehousing and fulfillment: a company that stores your inventory, picks and packs orders, and ships them, so you don't run your own warehouse. The "third party" is them; the first party is the seller, the second is the buyer.

The ladder, plainly

• 1PL — you deliver your own product. A bakery van.
• 2PL — you hire a carrier. UPS, FedEx, a freight line.
• 3PL — you hand off warehousing and fulfillment. They hold stock, pick, pack, ship, and usually handle returns. Amazon FBA is, functionally, the world's largest 3PL.
• 4PL — you hand off the management of multiple 3PLs and carriers. An orchestration layer, mostly for enterprises.

When a 3PL makes sense

• Order volume passes what a back room and a part-timer can pack reliably.
• You sell on several channels — your site, marketplaces, retail POs — and each has different labeling, prep, and speed requirements.
• Storage seasonality: you'd rather pay for space by the pallet-month than lease a warehouse for the December peak and heat it in July.
• You are entering marketplace fulfillment programs with strict receiving rules and would rather a specialist eat that complexity.

What it costs — the four meters

Every 3PL quote is some arrangement of the same four meters: receiving (per pallet or per hour), storage (per pallet or cubic foot, per month), pick & pack (per order plus per unit), and outbound postage (their negotiated rates, ideally passed through with a visible markup). The quote that looks cheapest usually has one meter hidden. Ask for all four.

Questions that separate real operators from brokers

1. Who owns the warehouse — you, or a partner I've never heard of?
2. What's your receiving turnaround SLA in peak season, in writing?
3. Show me your billing file format — can I audit per-order charges?
4. What marketplace prep are you certified for — FBA receiving rules, retail routing guides?
5. What happens to my inventory if we part ways — transfer terms and timing?

A distributor that runs its own multi-channel logistics learns these answers the hard way. That operating experience — not a brochure — is what we bring to brand conversations about where inventory should sit and who should touch it.
