Pick and pack is the part of order fulfillment where someone pulls the items for an order off a shelf (the pick), puts them in the right box with the right protection, packing slip and label (the pack), and hands the sealed package to a carrier. At a third-party logistics company (a 3PL) the same work is done by its team, inside its warehouse system, for your orders.
The catch in handing it over is that your judgment leaves the packing table. Today you decide, order by order, which box an item goes in, who gets a thank-you card and whether a 4pm order ships tonight. Once a warehouse has them, a packing spec you wrote makes those calls, a barcode scan decides whether an item matches the order, and the cutoff time decides what ships today. The warehouse does what the spec says and nothing more. That is why the list of what you hand over matters more than any picking method, and why a quote line that just says "pick and pack" needs reading before you sign.
What pick and pack covers at a 3PL
A 3PL's pick and pack is more than the two verbs. An order moves through the warehouse like this:
- Receiving. Your inventory arrives, gets counted against what you said you sent, checked for damage and logged into the warehouse system.
- Putaway. Each product (each SKU) gets a tracked storage spot, a bin, shelf or pallet position, so it can be found again.
- Order sync. A new order flows from your store into the warehouse system automatically, through a connection to Shopify or whatever platform you sell on. Nobody retypes it.
- Pick. The system turns the order into a pick list with items, quantities and locations, and a picker pulls them. In a well-run warehouse the picker scans each item's barcode so the system confirms it matches the order.
- Pack. A packer checks the picked items against the order, often with a second scan, chooses a right-sized box or mailer, adds protection, inserts and the packing slip, and seals it.
- Ship. The package gets a carrier label, leaves on the next carrier pickup, and the tracking number flows back to your store so the customer's order shows as shipped.
When a quote lists "pick and pack" as a fee, it usually means the pick and pack steps only. Receiving, storage and postage are separate lines, and the quote section further down shows how they split. For the whole path from receiving to returns, see how ecommerce fulfillment works.
One note on the words, since the search results mix them up. A pick packer (or picker packer) is the warehouse employee who does this work: pulls items for orders, packs them and gets them ready for the carrier. Some warehouses split the job into pickers and packers; smaller ones combine it. The service a 3PL sells is the same work, done by its own team, for your orders.
What changes when you stop packing orders yourself
Three things change, and they are worth separating: what you hand over, what you stop controlling, and what stays yours.
What you hand over
A warehouse can't pick and pack what it can't identify or doesn't have rules for. Expect to provide:
- A barcode on every unit, or permission to apply one. Scan verification depends on it. If your products don't carry barcodes, the 3PL applies them at receiving, usually for a per-unit charge.
- A product list with dimensions and weights. The warehouse system uses these to choose packaging and estimate postage.
- A packing spec per product. Which items ship in a box and which in a mailer, what needs bubble or paper, and what can't travel together (glass next to candles, liquids on their side).
- Insert and note rules. Which orders get a thank-you card, a sample or a gift note, and where the text comes from.
- Kit and bundle definitions. If a "starter set" in your store is three SKUs in one box, the warehouse needs to know whether to pick three items or one pre-built kit. Kitting and assembly is usually its own line on the quote.
- A store connection. Access to connect your sales channels, plus a decision about which orders route to the warehouse: all of them, or only some.
- Branded packaging, if you use it. You design and order it; the warehouse stores it and uses it on the orders you specify.
A 3PL's onboarding is mostly collecting this list, so the decision to make before you sign is how much of it you want to specify. Anything you leave out, the warehouse either fills in with its own default (a standard box or mailer, no insert) or holds those orders until you answer. Either is fine if you chose it and a problem if it surprises you, so ask which one your provider does.
What you stop controlling day to day
The cutoff, the packing spec and the scan now make the calls you used to make at the table. For most founders that is exactly what they wanted, but it's still a loss of touch, and it's why the packing spec matters so much. It's the only place your judgment still lives inside the warehouse.
What you still own
Everything before the order and after the delivery is still yours: product listings, inventory buying and reorder points, customer service, your shipping and returns policies, and which carriers and services the warehouse may use for your orders. The 3PL executes. You set the rules and watch the numbers.
When self-packing stops working
There's no order count at which you must outsource. The real signals are about time and errors:
- Packing takes a block of hours every day that you'd otherwise spend on product, marketing or sleep.
- Wrong-item and missing-item reships are a regular line in your month, not an occasional one.
- You learn about stockouts at the packing table instead of in a report.
- You can't get sick or take a weekend without orders sitting.
- A holiday peak or a first wholesale order would break the current setup.
Do the math honestly: the hours you spend and what they are worth, the cost of your reships, and your packaging and postage at retail rates against a 3PL's. Then read in-house fulfillment versus a 3PL, which walks through that decision properly. Keeping it in-house for now is a reasonable answer for a small brand, and so is handing it off before the next peak.
How pick and pack shows up on a quote
This is where founders get confused, because two 3PLs can quote the same job in very different shapes.
- A per-order fee with picks counted. Some providers charge one fee per order that includes the first pick, then a smaller charge for each additional item picked. Billed that way, a three-item order costs the base plus two extra picks.
- Separate pick and pack lines. A per-pick fee and a per-package pack fee, sometimes with packaging materials billed on top. Cheap picks can hide an expensive pack line.
- A flat rate per order. One price that bundles pick, pack, packaging and postage. Easier to forecast; the detail is in what counts as a standard order.
What to check: how many picks are included, whether packaging is in the price or a separate charge, and whether postage is passed through at cost or marked up. Each of those can change what even a one-item order costs, and a multi-item order in a branded box with an insert touches all three of those lines at once. Compare the complete quote for your actual order mix, not the headline pick fee.
Numbers belong in one place. The 3PL fulfillment pricing guide covers typical pick, pack, storage and receiving rates and how to compare quotes line by line. Simpl bills a flat rate per order, starting at $7/order, that includes picks, packing, postage and packaging; carrier surcharges, when they apply, are billed per our terms.
Picking methods, and why you don't pick one
Every warehouse page lists picking methods. The method is the warehouse's choice, not yours, but knowing the names helps you read the answer when you ask how your orders will move.
- Piece picking. One picker, one order, start to finish. Simple and easy to audit; travel time adds up as volume grows.
- Batch picking. One picker pulls several orders in one trip, then sorts them at the pack station. Cuts walking when orders share products.
- Zone picking. Each picker owns a section of the warehouse and pulls their part of every order; the system reassembles the order before packing.
- Wave picking. Batches scheduled across zones by the warehouse software, timed to carrier pickups. Built for high volumes.
Piece and batch picking are common in smaller warehouses, and a direct-to-consumer brand's orders don't need anything fancier. The question to ask is "how will my orders be picked, and how do you verify them?" A provider who can answer in two sentences has thought about it.
How to tell whether a 3PL does pick and pack well
Every provider claims accuracy and speed. Ask for the mechanism behind each claim. These are the pick-and-pack questions; how to choose a 3PL covers the rest, such as contracts, location and pricing.
- What the accuracy rate counts. Order accuracy is the share of shipped orders that went out with the right items, quantities and label. A quoted 99.5% is only as good as the counting behind it, so ask whether it comes from scan data on every order or from customer complaints, what counts as an error, and over what period. Order accuracy walks through the formula.
- What keeps the rate high. The good answer is barcode scanning at pick and again at pack, so a wrong item is caught before the box is sealed. "Experienced staff" is not a control.
- Who pays when an order ships wrong. A provider who stands behind its number covers the return shipping and the reship. One who bills you for its own mistake has told you what the number is worth.
- The same-day cutoff. The time an order must arrive to ship that day. A later cutoff means more of your afternoon orders leave today instead of tomorrow.
- Multi-item orders, kits and branded packaging. Ask how a five-item order is verified, whether kits are pre-built or picked at order time, and whether your custom box and inserts are handled as standard or as a special request.
- What you can see. Inventory counts and order status should be live, not in a weekly email. Ask which warehouse software they run and what you get access to.
- Store integration. Orders should sync from your platform automatically, and tracking should sync back.
- A person who answers. When a pallet arrives short or a carrier loses a box, you want a named human, not a ticket queue.
As a concrete example, here is how Simpl answers the same questions. We run pick and pack on ShipHero with real-time inventory visibility. Orders sync in from Shopify, Amazon, WooCommerce, Walmart, eBay, Etsy and TikTok Shop, and tracking syncs back to the order. Orders received before 12pm CT ship the same day. Order accuracy runs 99.99%, and when an error does happen we correct it at our cost, covering the return shipping and the re-fulfillment. Kitting, gift wrapping and handwritten notes are available, and every client has a dedicated account manager reachable by email. The ecommerce fulfillment page has the detail. Ask any other provider for the same list. The answers are the comparison.
