3PL (third-party logistics)
A 3PL (third-party logistics) provider is a company that stores your inventory, packs orders and ships them to customers on your behalf for a fee.
What is a 3PL?
A 3PL, short for third-party logistics, is an outside company that handles the physical side of selling online. You send your stock to its warehouse, and it receives, stores, picks, packs and ships each order when a customer buys. Many 3PLs also handle returns, kitting and international shipping. For an online store, a 3PL matters because fulfillment speed and accuracy shape the customer experience, reviews and repeat purchases. It also frees the founder from packing boxes, so time goes into products, marketing and growth instead. Most 3PLs connect directly to Shopify, so orders flow to the warehouse automatically without manual copying or spreadsheets.
How a 3PL works
The process starts when you ship inventory to the 3PL’s warehouse, where staff count it and add it to their system. Your store is connected through an app or integration, so every new order is sent to the warehouse within minutes. A picker collects the items, a packer boxes them, and the carrier label is printed with tracking that syncs back to your store. For example, a brand selling 500 orders a month might pay a receiving fee per pallet, a storage fee per shelf or bin, and a pick-and-pack fee per order, plus postage. The 3PL sends one monthly invoice covering all of it.
When to use a 3PL
A 3PL usually makes sense once packing orders yourself takes more time than it is worth, or when you need faster delivery in regions far from your base. Brands often switch when they reach a steady daily order volume, run out of space at home, or plan a big promotion that would swamp a small team. The main benefits are scale, carrier discounts and fewer shipping mistakes. The trade-offs are less direct control, minimum volumes or fees at some providers, and the risk of stock errors if counts are not checked. Very small or highly custom products are sometimes better fulfilled in-house.
Best practices for working with a 3PL
Start by comparing total cost per order, not just the pick fee, since storage, receiving and packaging add up. Ask for the provider’s order cutoff time and same-day shipping rate, then test it with a few real orders before moving all stock. Keep product data clean, with accurate SKUs, weights and barcodes, so picks are correct and postage is not overcharged. Review inventory reports every week and reconcile them with your store to catch shrinkage early. Agree on how returns are inspected and restocked. Finally, choose a warehouse location close to most of your customers to cut delivery time and shipping cost.
3PL vs dropshipping
With a 3PL you buy and own the inventory, and the 3PL only stores and ships it for you. With dropshipping you never hold stock: the supplier ships each order straight to the customer after you pass it on. A 3PL gives you more control over packaging, delivery speed and product quality, but it requires buying inventory upfront and paying storage. Dropshipping needs little capital and no warehouse, but delivery is often slower and branding is limited. Many brands start with dropshipping to test demand, then move proven products into a 3PL once they know what sells and can commit to stock.
Questions
- How much does a 3PL cost?
- Pricing varies by provider and volume, but most 3PLs charge a receiving fee when stock arrives, a monthly storage fee, a pick-and-pack fee per order, and the postage itself. Some add account minimums or packaging fees, so always compare the total cost per order.
- When should a Shopify store switch to a 3PL?
- Consider a 3PL when packing orders eats into time you need for growth, when you run out of storage space, or when customers far away wait too long for delivery. A steady order volume makes the per-order fees easier to justify.
