B2B Shipping: A Practical Guide to Business-to-Business Logistics

Business-to-business shipping operates in a fundamentally different world from the consumer packages most e-commerce sellers are used to. A typical B2B order weighs 150-500 pounds and ships on a pallet. The pricing model is based on freight class and lane rather than just weight and zone. A 300-pound shipment on a standard pallet might cost $180-350 via LTL freight, while sending the same weight as individual packages through UPS Ground would run $600 or more. Understanding how B2B logistics works — and specifically how LTL freight pricing differs from parcel shipping — can save a business 40-60% on large shipments.

How B2B Shipping Differs from B2C

The differences go beyond just package size. B2B customers expect professional documentation — packing lists that match purchase orders, commercial invoices with correct terms, and Bills of Lading (BOL) with accurate freight classifications. They often require delivery appointments scheduled in advance because their receiving docks operate on fixed schedules with limited capacity. A missed delivery window means your shipment sits on the carrier's truck until the next available appointment, which might be the following day.

Delivery destinations in B2B are typically commercial addresses with loading docks, which simplifies the physical delivery process but adds documentation and scheduling requirements. If a B2B customer does not have a loading dock — a small retail store or a home office — you need liftgate service, which adds $50-100 per delivery. Inside delivery, where the driver brings the freight beyond the threshold, is another $50-100.

Payment terms are standard in B2B and rarely exist in B2C. Your B2B customers may expect Net 30 or Net 60 payment terms, which means you are fronting the shipping cost for a month or two before the invoice is paid. Building shipping costs into your B2B pricing (rather than charging separately) simplifies accounting and avoids disputes over carrier surcharges.

Parcel vs. LTL vs. Full Truckload

The shipping method depends primarily on the size and weight of the order.

Parcel shipping through UPS, FedEx, or USPS makes sense for smaller B2B orders — sample shipments, individual replacement parts, or small restock orders under about 150 pounds. The rates, services, and processes are essentially the same as B2C parcel shipping, with the exception that commercial addresses typically avoid residential surcharges ($5-6 per package with UPS and FedEx), making the per-package cost slightly lower than equivalent residential deliveries.

LTL (Less-Than-Truckload) freight is the workhouse of B2B shipping for orders between 150 and about 10,000 pounds. Your palletized freight shares truck space with other shippers' cargo, similar to how a parcel shares space in a delivery truck with other packages. The carrier picks up your pallet, moves it through their terminal network, and delivers it to your customer's dock.

LTL pricing is more complex than parcel pricing because it factors in four variables: weight, freight class, distance, and accessorial services. Weight and distance are straightforward. Freight class is the variable that trips up most businesses new to LTL. Every product is assigned a freight class between 50 and 500 based on its density, handling difficulty, stowability, and liability. Dense, easy-to-handle products like pallets of bottled water are class 50 (cheapest). Light, fragile, irregularly shaped items might be class 175 or higher (most expensive). Getting the freight class right matters because misclassification leads to reclassification charges after the carrier inspects the shipment.

Full Truckload (FTL) becomes cost-effective when you are shipping 10,000+ pounds or enough pallets to fill most of a trailer (typically 10-24 pallets depending on size). FTL is simpler than LTL — you are renting the entire truck from origin to destination with no terminal transfers or shared cargo. Transit times are shorter because the truck goes directly from pickup to delivery without stopping at intermediate terminals. Rates are quoted per mile or per load rather than by weight and class.

Freight Classification

The National Motor Freight Classification (NMFC) system assigns every product a freight class. The class determines the rate per hundredweight (CWT) that the carrier charges. Lower class numbers mean the product is dense and easy to ship — higher numbers mean it is bulky, fragile, or difficult to handle.

Common freight classes for typical B2B products: machinery and metal parts often fall in class 50-70. Boxed electronics are typically class 85-100. Furniture ranges from class 100-175 depending on density and fragility. Lightweight but bulky items like unassembled furniture or plastic products can reach class 200 or higher.

Calculating your freight class starts with density: weigh the shipment including packaging and pallets, measure the total dimensions, and divide weight by cubic feet. A shipment that weighs 500 pounds and occupies 40 cubic feet has a density of 12.5 pounds per cubic foot, which would typically fall around class 70-85. Your carrier or freight broker can help determine the correct NMFC code for your specific product, and it is worth getting this right because an incorrect class can result in either overpaying (if you declare a higher class than necessary) or reclassification charges (if the carrier determines your declared class is too low).

Palletization and Packaging for Freight

B2B shipments typically move on standard 48x40 inch pallets. Proper palletization is not optional — it directly affects whether your freight arrives undamaged and whether the carrier accepts it without issue.

Stack boxes evenly on the pallet with no overhang past the pallet edges. Overhang creates instability during forklift handling and can result in the carrier refusing the shipment or charging for repackaging. Stretch wrap the entire pallet thoroughly — wrap at least 5-6 times around the base, anchoring the wrap to the pallet itself, then work up to the top. The stretch wrap is what keeps the load stable during transit.

For heavy or tall pallets, add corner boards (cardboard angle pieces on the vertical corners) before stretch wrapping. These distribute compression forces and prevent the wrap from cutting into boxes on the corners. For fragile items, double-wall corrugated boxes and additional internal packaging are essential because LTL freight gets handled more roughly than parcel — pallets are moved by forklift, loaded and unloaded at multiple terminals, and share trailer space with other cargo that can shift.

Label the pallet clearly with the destination address, BOL number, and any special handling instructions. Place labels on at least two sides of the pallet so they are visible regardless of how the pallet is positioned in the trailer.

Managing B2B Shipping Costs

The biggest cost lever in B2B shipping is choosing the right mode for each shipment. Many businesses default to parcel shipping for everything, including orders that would be significantly cheaper as LTL freight. A 200-pound order shipped as ten 20-pound parcels via UPS Ground might cost $250-400 total, while the same 200 pounds consolidated onto a single pallet and shipped LTL might cost $120-200. The rule of thumb is that LTL becomes more cost-effective than parcel at around 150 pounds or 4-5 boxes, though the exact crossover depends on distance and freight class.

Negotiating carrier rates makes a bigger difference in B2B than in B2C because the per-shipment dollar amounts are higher. A 10% discount on a $300 LTL shipment saves $30, versus 10% on a $7 parcel saving $0.70. Most LTL carriers will negotiate rates for businesses shipping regularly, and freight brokers can often secure better rates than you would get directly by leveraging their aggregate volume across multiple clients.

Shipping platforms like Atoship that compare rates across both parcel and LTL carriers help B2B businesses identify the most cost-effective mode for each shipment, automatically determining whether parcel or freight makes more sense based on the order's weight, dimensions, and destination.
