A 3PL (third-party logistics) provider stores your inventory, picks and packs your orders, and ships them to customers. Brands hire a 3PL when in-house fulfillment starts stealing time from product, marketing, and growth — usually somewhere between 200 and 500 orders per month.
What a 3PL actually does
A third-party logistics provider is the operations team your brand doesn't have to hire. You ship inventory to their warehouse. They receive it, count it, and store it. When an order lands in your Shopify or Amazon account, their WMS pulls the order, a picker grabs the items, a packer boxes them, and a carrier picks up the package the same day.
The best 3PLs handle everything downstream of checkout: receiving, storage, pick and pack, custom packaging, kitting, shipping, returns, and reporting. You keep control of the brand, the product, and the customer — they run the physical operation.
3PL vs 4PL vs fulfillment center: quick definitions
The terms get muddled in sales pitches. Here's the honest version:
• 3PL — Runs the warehouse and fulfillment operation for you. Most DTC brands need this.
• Fulfillment center — Usually a synonym for a 3PL warehouse, especially for ecommerce-first providers.
• 4PL — Manages your 3PLs and freight partners on your behalf. Overkill until you're running multiple warehouses on multiple continents.
• Freight forwarder — Moves inventory internationally into a 3PL or FBA. A different service, often bundled.
What does a 3PL cost?
Most 3PLs charge across five line items: receiving, storage, pick and pack, packaging materials, and shipping (usually passed through at their negotiated carrier rates). Expect a typical ecommerce order to cost $3.50 to $6.50 to fulfill before postage, depending on complexity.
The honest thing to look for isn't the lowest rate card — it's a quote that maps to your actual SKU count, order profile, and packaging. Any 3PL that quotes you before understanding those three things is guessing.
When should you hire a 3PL?
There is no magic order volume, but there are clear signals. Founders usually make the move when one of these hits:
• You're spending more than 10 hours a week packing orders.
• Shipping errors are creeping into your support inbox.
• You've outgrown a garage or a small studio and the next lease is scary.
• You're launching wholesale, retail, or Amazon and need parallel operations.
What to ask before signing a 3PL contract
Fulfillment contracts don't have to be scary, but they should be specific. Before signing, get written answers on same-day cutoffs, order accuracy SLAs, peak-season surcharges, onboarding timelines, and what happens if you want to leave.
A partner worth keeping will answer all of these in plain English. If the sales rep hedges, treat that as data.
FAQs
What does 3PL stand for?
3PL stands for third-party logistics. It refers to a company that stores your inventory and ships orders to your customers on your behalf, so you don't have to run a warehouse yourself.
How much does a 3PL cost per order?
Most ecommerce brands pay between $3.50 and $6.50 per order for pick, pack, and materials, plus pass-through carrier rates for shipping. Storage is billed separately by pallet, shelf, or cubic foot.
Is a 3PL the same as a fulfillment center?
In ecommerce, the terms are used interchangeably. A fulfillment center is typically an ecommerce-focused 3PL warehouse. Technically, a 3PL is the company and a fulfillment center is the physical building they operate.
When should I hire a 3PL?
Most DTC brands move to a 3PL between 200 and 500 orders per month, or as soon as fulfillment is stealing more than 10 hours a week from product, marketing, or growth work.
