A 3PL (third-party logistics provider) stores your products and then picks, packs and ships your orders for you. Most brands are ready for one when fulfillment starts eating the hours they should be spending on growth — commonly somewhere between a few hundred orders a month and the first time a launch or a holiday buries them.
What a 3PL actually does
The one-sentence definition covers the core of it, but a modern fulfillment partner does more than move boxes. The work breaks into five steps, and it is worth understanding each one because every 3PL quote you ever read is built out of them.
Receiving
Your inventory arrives at the warehouse and is counted, inspected and logged into the system. This is where discrepancies get caught — short shipments, damaged cases, mislabeled cartons. Some 3PLs bill receiving by the hour, the pallet or the unit. (At Minimus, receiving is free; it is not a line item on your invoice.)
Warehousing
Products are stored on shelves, in bins or on pallets, with stock levels tracked so you always know what you have and where. Storage is usually billed monthly by pallet, shelf or bin.
Pick and pack
When an order comes in, someone picks the right items, packs them in the right box or mailer and adds any inserts or branded touches. This is the step most people picture when they think about fulfillment, and it is the step where accuracy either happens or does not.
Shipping
The order is labeled and handed to a carrier — FedEx, USPS, or LTL freight for pallets — usually at rates far below what a small brand could negotiate on its own. High-volume 3PLs carry national carrier accounts and pass the discount through.
Returns
Most 3PLs also process returns: inspecting what comes back, restocking what is sellable and disposing of what is not.
Behind all of it sits software that connects to your store so orders flow in automatically and tracking flows back out to your customers. We run ShipStation as the hub, which connects to Shopify, Amazon, WooCommerce, BigCommerce, Walmart, TikTok Shop, Etsy and eBay, among others.
The signs you are ready
There is no magic order count, but there are reliable symptoms. Any two of these usually mean it is time:
- Fulfillment is eating your week. The hours you spend taping boxes are hours you are not spending on product, marketing or accounts.
- Volume has passed what you can pack reliably by hand. For most teams that is somewhere in the low hundreds of orders per month.
- Mistakes are showing up. Wrong items, late ships, angry emails. Accuracy degrades long before capacity does.
- Your postage is too expensive. Retail carrier rates are punishing without volume behind them.
- You are adding complexity. Wholesale, retail, subscriptions or Amazon each bring their own rules, and they multiply rather than add.
- Space has run out. When inventory moves from the spare room to a storage unit, the economics have already turned.
What outsourcing does not solve
It is worth being honest about the other side. A 3PL does not fix bad demand planning, and it does not make a thin margin healthy. It adds a handoff, which means your data has to be clean and your SKUs have to be properly identified. And it introduces a dependency: if your partner is slow to answer, that becomes your problem in front of your customers. Which is the whole reason the choice of partner matters more than the decision to outsource.
Choosing a partner, not just a warehouse
Any 3PL can put a product in a bag. The difference shows up in accuracy, in communication, and in whether the team treats your brand like their own. We came out of building and running consumer brands rather than out of logistics, and we ship DTC and B2B from our own FDA-registered warehouse in Thousand Oaks, California — with an order error rate under 1%, customer service staffed on site with the inventory, and packaging and kitting handled in house.
If you are weighing whether it is time, tell us what you ship and we will give you a straight answer — including if the answer is "not yet."
