What Is a 3PL?
Third-party logistics, explained.
A 3PL is a company that stores your inventory and ships your orders so you don't have to. Here's exactly what that covers, what it costs, and how to know when you need one — from a team that runs a 250,000 sqft 3PL warehouse in Los Angeles.
- 1.
Third-party logistics. The outsourcing of warehousing, inventory management, order fulfillment, and shipping to a specialized provider.
- 2.
A company that performs these services; a fulfillment partner. “We moved out of the garage and into a 3PL at 400 orders a month.”
3PL stands for third-party logistics. A 3PL receives your inventory, stores it in a warehouse, and when customers order, picks, packs, and ships each order under discounted carrier rates. Brands use 3PLs to get professional fulfillment — same-day shipping, 99%+ accuracy, real-time inventory — without leasing warehouses or hiring warehouse staff. Typical cost: $2.50-4.50 per order plus storage.
1PL to 5PL: Where “Third-Party” Comes From
The number counts how many parties stand between your product and your customer. Most growing e-commerce brands live at exactly one rung: 3PL.
You do everything yourself — your products, your van, your deliveries.
A local bakery delivering its own cakes
You hire carriers to move goods, but manage everything else.
A brand shipping via UPS from its own garage
A partner stores your inventory and fulfills your orders end to end.
An e-commerce brand using a fulfillment warehouse
A manager coordinates multiple 3PLs and carriers on your behalf.
An enterprise orchestrating a global network
Aggregators managing whole supply networks, often tech-driven.
Large-scale supply chain platforms
What a 3PL Actually Does
Follow one product through the warehouse — from the container it arrives in to the customer's doorstep.
Your inventory arrives
Containers and pallets are checked in, counted, inspected, and put away into barcoded bin locations — usually within 24-48 hours of hitting the dock. Order fulfillment →
Stored and tracked in real time
Inventory lives in pallet racks, shelves, or bins. A WMS tracks every unit by location, and you see live counts synced to your store. Our WMS →
Orders picked and packed
When a customer buys, the order syncs automatically. Items are scan-verified at picking, packed in right-sized boxes with proper dunnage, and labeled. Pick and pack services →
Shipped at negotiated rates
Carriers pick up daily. Orders in by 2 PM PT ship the same day, and tracking flows back to your store and customer instantly. E-commerce fulfillment →
Returns processed
Returned items are received, inspected, and restocked or quarantined per your rules — closing the loop without you touching a box.
Beyond the basics, most 3PLs also offer:
3PL vs. In-House vs. FBA vs. Dropshipping
Four ways to get a product to a customer. The right one depends on your volume, margin, and how much control you want.
| In-House | 3PL | Amazon FBA | Dropshipping | |
|---|---|---|---|---|
| Upfront cost | High — space, shelving, labor | None — pay per use | None, but strict prep rules | None |
| Cost per order | Hidden in rent + your time | $2.50-4.50 + items | Fees by size/weight tier | Highest per-unit margin cost |
| Branding control | Total | Total — custom packaging | None (Amazon box) | Minimal |
| Sales channels | All | All — D2C, Amazon, retail, B2B | Amazon-centric | Wherever supplier allows |
| Scales with growth | Poorly — you hire and lease | Automatically | Yes, within Amazon | Yes, low ceiling on margin |
| Best for | Under ~300 orders/mo | Growing multi-channel brands | Amazon-first sellers | Testing products, no inventory |
These aren't mutually exclusive. A common setup for growing brands: FBA for Amazon Prime orders, a 3PL for the website, TikTok Shop, retail, and FBA prep — one inventory pool feeding every channel. See the full comparison in our guide to FBA vs. 3PL costs.
When Do You Need a 3PL?
There's no perfect order count, but the tipping point for most brands lands around 300 orders per month — the volume where a 3PL's per-order fees usually cost less than your own time, space, and retail shipping rates.
Below that, self-fulfillment is often fine. Above it, every hour at the packing table is an hour not spent on the product, marketing, or sales — and the math keeps tilting as you grow.

Signs it's time
- ✓You spend 2+ hours a day packing orders instead of growing the business
- ✓Inventory has outgrown your garage, office, or storage unit
- ✓You're paying retail shipping rates with no carrier discounts
- ✓Order mistakes and late shipments are generating support tickets
- ✓Sales spike during promotions and you can't keep up
- ✓You want to sell on Amazon, TikTok Shop, or into retail — each with its own requirements
- ✓Storage, labor, and shipping costs are impossible to forecast
What a 3PL Costs
3PL pricing is built from a handful of per-use fees. Here's the typical structure for a D2C e-commerce brand:
| Fee | Charged | Typical Range |
|---|---|---|
| Pick & pack | Per order + per extra item | $2.50-4.50 + $0.50-1.00 |
| Storage | Per pallet or bin, monthly | $20-35 / pallet |
| Receiving | Per pallet or container | $35-50 / pallet |
| Packaging materials | Per order | At cost |
| Shipping | Per parcel, discounted rates | Pass-through |
Watch for the fees that aren't on the quote: setup charges, monthly minimums, account management fees, and peak-season surcharges. Our full breakdown is in 3PL pricing explained, and our own rates are on the pricing page — no setup fees, no minimums, no long-term contracts.
