- Is a 3PL worth it?
A 3PL, short for third-party logistics provider, is a company that receives a seller's stock, stores it in its warehouse and ships orders to customers on the seller's behalf. The shop keeps control of its products, prices and marketing; the 3PL handles the physical work of getting parcels out of the door.
For a small online shop, that usually means the moment when the spare room, the garage and every weekend have been swallowed by packing tape.
What a 3PL actually does
- Receiving — checking in deliveries from manufacturers or suppliers, counting units and noting damage.
- Storage — keeping goods on shelves, in bins or on pallet racking, tracked by product code.
- Pick and pack — collecting the right items for each order and packing them, sometimes with inserts or gift notes.
- Shipping — printing labels, handing parcels to carriers and passing tracking numbers back to the shop.
- Returns — receiving items sent back, inspecting them and restocking or setting aside damaged units.
- Extras — kitting (assembling bundles), labelling, and in some cases business-to-business deliveries to retailers.
What is order fulfillment, exactly?
Order fulfillment is the full chain of steps between a customer pressing "buy" and the parcel arriving. With a 3PL in place it typically runs like this:
- The shop's platform sends the order to the 3PL's system through an integration.
- The warehouse system matches each line to a stored product code and its shelf location.
- A picker collects the items; a packer chooses the box and packing material.
- A label is printed with the carrier service the shop has chosen or the 3PL has rated.
- The carrier collects the parcel, and tracking details flow back to the shop and the customer.
Everything in that chain depends on clean product data. A 3PL will ask for a unique code for every variant, which is why it pays to create SKU numbers that follow a clear system before stock ever leaves for the warehouse.
1PL, 2PL, 3PL and 4PL in one table
| Term | Who does the work | Typical example |
|---|---|---|
| 1PL | The business itself | The owner packs and posts orders from home |
| 2PL | A carrier that moves goods | A parcel service or haulier collecting shipments |
| 3PL | An outside provider handling storage and fulfilment | A warehouse that picks, packs and ships online orders |
| 4PL | A manager that coordinates several logistics partners | A firm overseeing multiple warehouses and carriers for a larger brand |
How 3PL pricing is usually structured
Rates vary widely by provider, region and volume, so the useful thing is to know the types of charges and compare quotes line by line:
- A setup or onboarding fee, sometimes waived.
- Receiving fees per pallet, carton or hour of labour.
- Storage fees per pallet, shelf or bin, usually charged monthly.
- Pick and pack fees per order, often with a smaller charge per additional item.
- Packaging materials, if the 3PL supplies boxes and fillers.
- Shipping labels at the provider's carrier rates.
- Returns processing and any special projects such as relabelling.
- Monthly minimums that apply even in quiet months.
Slow-selling stock is where storage fees quietly add up, so a stock review before moving in is worth the effort.
3PL, in-house shipping or dropshipping?
| Option | Suits | Watch out for |
|---|---|---|
| Ship in-house | Early shops, handmade goods, low order volume | Owner time, space and carrier rates without volume |
| 3PL | Shops with steady volume and their own stock | Minimums, storage on slow sellers, less hands-on packing |
| Dropshipping | Testing products without buying stock | Little control over quality and delivery; see whether dropshipping is legal and where it goes wrong |
One more reason shops move to a 3PL is distance. A provider with warehouses in several regions can ship from the location nearest each customer, which keeps more parcels in the cheaper shipping zones.
Questions to ask before signing
- Does the warehouse system connect directly to your shop platform?
- What are the daily cut-off times for same-day dispatch?
- How are picking errors measured, reported and put right?
- Which barcodes or labels must inbound stock carry?
- Who is liable for damage or loss in storage, and what insurance is in place?
- How long is the contract, and what happens to your stock if you leave?
- Can the warehouse handle your packaging, inserts and any oversized items?
Inbound deliveries usually arrive on pallets, and unusually shaped goods may travel better on custom-built pallets than on standard ones.
Is a 3PL worth it?
It tends to make sense when packing has become the bottleneck rather than the business, when storage space has run out, or when delivery promises are slipping. It makes less sense for very low volumes, highly customised orders or products where the personal touch of the maker is part of what customers pay for. Ask two or three providers for quotes based on your real order history, and compare the total monthly cost with what in-house fulfilment truly costs once your own time is counted.
