Inbound vs Outbound Logistics: Meaning, Examples and Costs (2026)
Quick answer: Inbound logistics is everything that brings goods into your business: ordering from suppliers, moving the goods to your warehouse, counting and checking them, and putting them on the shelf. Outbound logistics is everything that takes goods out to buyers: receiving orders, picking, packing, handing parcels to a carrier and getting them delivered. Returns flow back in and are usually counted as inbound (reverse logistics). For an online store that sources from China, inbound normally ends when stock is shelved in a China warehouse, and outbound starts the moment a customer's order reaches that warehouse.
Inbound vs outbound at a glance
| Inbound logistics | Outbound logistics | |
|---|---|---|
| Direction | Supplier to your warehouse | Your warehouse to the customer (or to another warehouse) |
| Starts with | A purchase order | A paid customer order |
| Ends with | Counted, checked stock on a shelf, ready to sell | A delivered parcel and a tracking record |
| Typical batch | Cartons and pallets of one SKU | Single parcels with one or a few items |
| Who you deal with | Factories, wholesalers, freight carriers | Parcel carriers, customs at the destination, your customers |
| What goes wrong | Short shipments, wrong specs, defects found too late | Wrong item packed, late dispatch, lost parcels, duty bills at the door |
| Who notices first | You, if you check; your customer, if you don't | Your customer |
The simplest way to remember it: inbound protects your stock, outbound protects your reviews. A mistake on the inbound side is cheap to fix while the goods are still in a warehouse. The same mistake found on the outbound side is a refund, a return and an unhappy buyer.
One shipment can be both
"Inbound" and "outbound" describe direction from someone's point of view, so the same box can be both at once:
- Factory to a China warehouse. Outbound for the factory, inbound for the warehouse.
- China warehouse to Amazon. Outbound for the warehouse that preps it, but Seller Central calls it an "inbound shipment", because it is coming into Amazon's network. Our guide to getting products from suppliers to FBA compares the routes.
- Bulk freight to an overseas warehouse. Outbound from China, inbound to the overseas 3PL, which then runs its own outbound parcels to customers.
- A customer return. Outbound for the customer, inbound for you.
When a supplier, a forwarder and a warehouse argue about a missing carton, agreeing on whose inbound it was, and who signed for it, usually settles the question.
Inbound, step by step, for goods made in China
- Purchase order. Quantity, unit price, specs, packaging, delivery date and delivery address, in writing. A vague purchase order is the root of most inbound problems.
- Supplier dispatch. The factory or wholesaler sends the goods to your warehouse by domestic courier or truck. Ask for a packing list and photos of the sealed cartons before they leave.
- Receiving. The warehouse counts cartons and units against the purchase order and records any shortfall the same day.
- Inspection. A share of units is checked against the approved sample: function, color, size, packaging. This is the last cheap moment to reject a bad batch.
- Labelling and SKU mapping. The supplier's product code is matched to your store's SKU, and units get barcodes if they need them.
- Put-away. Stock goes onto a shelf location and becomes available to sell.
Three instructions to give every supplier make receiving much faster: write your purchase order number on every carton, keep one SKU per carton where possible, and send the packing list before the truck arrives.
Outbound, step by step
- Order intake. Orders go from your store to the warehouse. With PackQuay, message us on WhatsApp and we connect your Shopify or WooCommerce store for you. Orders come in automatically, and tracking numbers go back to your store once parcels ship. You can also send orders as a CSV or Excel file.
- Order check and allocation. Address, stock and shipping line are confirmed before anything is picked.
- Pick and pack. The right units are picked by SKU and packed in your mailer or box, with inserts if you use them. Multi-item orders go out as one parcel.
- Carrier handover. The parcel is labelled, weighed and handed to the shipping line chosen for that destination.
- Tracking and delivery. The tracking number goes back to your store once the parcel ships, and the last-mile carrier delivers.

One part of outbound changed for good in 2025. The US $800 duty-free rule (de minimis) stopped applying to parcels from China and Hong Kong in May 2025 and to every country in August 2025; US Customs suspended it indefinitely in June 2026, and the law repeals it permanently from July 1, 2027. Every parcel from China to the US now owes duties, so outbound planning has to include them. Shipping duties paid (DDP) keeps that bill away from your customer's door.
Where the money goes
| Inbound costs | Outbound costs |
|---|---|
| Product cost | Pick and pack fee per order |
| Sourcing or purchasing fee | Packaging: mailers, boxes, inserts |
| Delivery from supplier to warehouse | International shipping |
| Inspection | Destination duties and taxes |
| Storage while stock waits to sell | Returns and re-shipments |
Inbound costs are mostly paid per batch and spread over every unit you sell. Outbound costs are paid per order, so they decide the margin on each sale. Both belong in your landed cost per order.
Worked example: pick and pack on a busy day
PackQuay's pick and pack fee depends on how many paid orders you have that day (Beijing time), and the rate drops as each tier is passed. Say a store has 60 single-item orders in a day:
- Orders 1–19 at $2.00: $38.00
- Orders 20–49 at $1.70: $51.00
- Orders 50–60 at $1.50: $16.50
- Total: $105.50, about $1.76 per order.
An order with a second, different SKU adds a per-SKU charge (for example $0.85 in the 20–49 tier), and extra units of the same SKU add a smaller per-unit charge. Shipping is charged at cost on top. The full table is on our pricing page.
The numbers worth tracking
| Side | Metric | What it tells you |
|---|---|---|
| Inbound | Supplier on-time rate | Whether your reorder lead times are realistic |
| Inbound | Days from arrival to sellable | How long stock sits uncounted; it belongs in your lead time |
| Inbound | Defect rate at inspection, per supplier | Which factory is slipping before your reviews show it |
| Outbound | Time from order to dispatch | Whether the warehouse is holding up delivery |
| Outbound | Order accuracy | Wrong-item complaints and returns |
| Outbound | Delivery time by destination | What delivery promise you can safely show at checkout |
| Both | Landed cost per order | Your real margin |
To see how inbound timing feeds your reorder decisions, read where a 3PL fits in your supply chain, which adds up the full lead time from factory to shelf.
How PackQuay handles both sides

FAQ
What is the difference between inbound and outbound logistics?
Inbound logistics brings goods into your business: purchasing, transport from suppliers, receiving, inspection and storage. Outbound logistics sends goods out: order processing, picking, packing, shipping and delivery to customers.
Are returns inbound or outbound logistics?
Returns are usually treated as inbound, because the goods come back into your warehouse to be checked and restocked or written off. The field is often called reverse logistics.
Is a shipment to Amazon FBA inbound or outbound?
Both, depending on who is speaking. It leaves your supplier or prep warehouse as an outbound shipment, and Amazon records it as an inbound shipment into its fulfillment network.
What are examples of inbound logistics costs?
Product cost, purchasing or sourcing fees, delivery from the supplier to the warehouse, inspection and storage. They are paid per batch and spread across every unit you sell.
How do I lower outbound logistics costs?
Combine multi-item orders into one parcel, choose the shipping line by destination and weight, use packaging that avoids paying for empty space, and move steady sellers to an overseas warehouse when volume justifies it. Order volume also matters: at PackQuay the pick and pack rate drops from $2.00 to $1.00 per order as daily volume grows.
