What it is
Third-party logistics, often shortened to 3PL, means hiring an outside company to handle some or all of the physical side of selling: receiving your stock, storing it, picking and packing orders, shipping them and often processing returns. You still own the goods and run the store. The provider runs the warehouse operation.
It is one of several fulfillment methods, and it sits between doing everything yourself and handing the whole job to a supplier. The choice usually comes down to your volume, your products and how much control you want.
What providers typically do
Services vary, but a typical provider offers some of the following:
- Receiving. Accepting inbound shipments, counting them and checking them against what you expected.
- Storage. Keeping goods on shelves, in bins or on pallets, sometimes with climate control for sensitive products.
- Order processing. Receiving orders from your store through an integration, then picking and packing them.
- Shipping. Booking carriers, printing labels and handing over parcels, often with negotiated rates.
- Returns handling. Receiving returned items, inspecting them and restocking or setting them aside.
- Inventory reporting. Providing stock counts and activity records.
- Extras. Kitting and bundling, custom inserts, gift wrapping, labeling or light assembly.
Not every provider does all of these, and some focus on certain product types, such as bulky goods, regulated items or small parcels.
How billing typically works
Pricing structures vary widely and are rarely identical between providers, so compare line by line rather than by headline numbers. The charges below are common in the industry, though not universal:
| Charge type | What it usually covers |
|---|---|
| Setup or onboarding | Connecting systems, creating your account, setting up product data |
| Receiving | Unloading, checking and shelving inbound stock |
| Storage | Space used, often by shelf, bin or pallet, billed periodically |
| Pick and pack | Per order and per additional item |
| Packaging materials | Boxes, mailers and fillers, if supplied by the provider |
| Shipping | Carrier charges, sometimes with a markup or discount |
| Returns processing | Per returned parcel or item |
| Special projects | Kitting, relabeling, inspections |
| Minimums | A minimum monthly spend or order count |
Because there are many small fees, a quoted pick-and-pack price may represent only a fraction of the total. Ask for an example invoice based on your typical month, and compare it against your current cost per order, including your own time. Our look at home fulfillment explains how to count that time honestly.
Keep in mind the effect on cash flow. You pay for stock before it sells, and then pay monthly fees on top. Slow-moving products can become expensive to store, which is a good reason to deal with dead stock early rather than leave it on a shelf you are paying for.
Benefits
- Time. You no longer pack orders, freeing your days for product, marketing and service.
- Scale. Providers can handle higher volumes and seasonal peaks.
- Shipping options. They may offer faster services or better rates than a small seller can obtain alone.
- Professional processes. Established receiving, counting and shipping routines.
Drawbacks
- Fees and minimums. Costs can be heavy at low volume.
- Less control. You cannot personally inspect each parcel. Packaging quality depends on the provider’s standards.
- Dependence. If the provider makes errors or runs late, your customers blame you.
- Complexity of change. Moving stock to another provider takes time and money.
- Inventory risk. Stock that is lost, damaged or miscounted in a warehouse can be hard to recover, depending on the terms.
Questions to ask before signing
Take your time with this list. Written answers are better than verbal promises.
Fit and capability
- What kinds of products do you handle, and which do you refuse?
- Do you have experience with items like mine, such as fragile, perishable or regulated goods?
- Which store systems do you connect with, and how do orders and stock counts sync?
Costs
- Can I see a complete fee schedule and a sample invoice for my expected volume?
- Are there minimums, setup fees or charges for inactive stock?
- How are shipping rates calculated, and who owns the carrier relationship?
Performance
- What are typical order cutoff times and processing times?
- What accuracy rate do you aim for, and how are errors handled?
- How is inventory counted, and how often?
Problems
- Who pays when an order is lost or damaged in your care or in transit?
- What is your policy on lost or damaged stock?
- How are returns handled and reported? Our article on return processing describes the steps you will want them to follow.
Contract
- What is the contract length, and how can I leave?
- What notice is needed, and how do I get my inventory back?
- What insurance do you carry, and does it cover my stock?
- How is my customer data stored and protected? Consider privacy obligations and your privacy policy.
Starting carefully
Many sellers start with a trial: a small batch of products, a short period, or a limited set of orders. Watch accuracy, speed and communication before sending everything. Order a few test orders to see the unboxing yourself. Keep clean product data, consistent SKUs and accurate weights and dimensions, since bad data causes costly errors in any warehouse.
Even with a provider, you remain responsible to the customer. Keep monitoring delivery times, error rates and costs per order, and be ready to renegotiate or switch if the numbers drift.
Third-party logistics is a tool, not a cure. It suits stores whose volume, products and margins make the fees worthwhile, and it works best when you have chosen the provider with a clear understanding of what you are paying for. Terms differ widely, so rely on the contract and not on general descriptions.
