Case Picks, Pallet Builds and LTL: How B2B Orders Move Differently Through the Warehouse
A wholesale purchase order is not a bigger parcel order. Units of measure, three levels of labeling, electronic paperwork and freight appointments all change how a B2B order moves through a fulfillment operation.
A brand that has shipped parcels for years often assumes its first wholesale purchase order is just a bigger version of what it already does. It is not. Almost nothing about a B2B order moves through a warehouse the way a consumer order does — different units of measure, different packaging, different paperwork, and a completely different way of leaving the building.
Everything starts with the unit of measure
A DTC operation deals almost entirely in eaches: one unit picked, packed, shipped. B2B introduces two more units above that, and they change the work at every step.
| Unit | What gets picked | Typical destination |
|---|---|---|
| Each | A single unit from a bin | Sample orders, small replenishment |
| Case | A sealed inner carton, untouched | Independent retailers, distributors |
| Pallet | A full pallet of cases | Distribution centers, large accounts |
The important consequence is that case picking should not involve opening the case. A case pick means a sealed carton moved from a rack to a pallet. If a picker has to open cases and count units, you have an each-pick wearing a case-pick's name, and it will take far longer than anyone estimated.
This is why case configuration matters. If a buyer wants twelve units and your case holds ten, someone is opening a case, counting out two, and repackaging. Aligning case quantities with how your accounts actually order removes a lot of hidden labor.
Building a pallet is a skill, not a step
Once cases are picked, they have to become a stable pallet. This gets described as "stacking boxes," which undersells it.
- Cube and weight distribution. Heavier cases on the bottom, the stack as close to a solid rectangle as case dimensions allow.
- Overhang. Cases hanging past the pallet edge lose much of their compression strength and are a common cause of in-transit damage.
- Height limits. Many receiving facilities cap pallet height, and a pallet built two inches over can be refused at the dock.
- Wrap. Enough tension and wraps around the top and base to bond the load to the pallet, not just decorate it.
A well-built pallet also protects the count. When a load arrives visibly intact, disputes about what was inside it are far easier to resolve.
Labeling happens at three levels
Parcel shipping has one label per box. B2B has a hierarchy, and each level answers a different question.
- Unit level. What the item is — often a retailer-specified barcode format rather than the one on your consumer packaging.
- Case level. What is inside this carton and how many. Larger accounts usually require a specific carton label format with its own serial number.
- Pallet level. What the whole load is, which shipment it belongs to, and which purchase order it fulfills.
Getting the structure right lets a receiving clerk scan a pallet and know its contents without opening anything. Getting it wrong is a common cause of deductions, because the facility has to do manual work your labels were supposed to eliminate. Retailer-specific requirements are usually spelled out in a routing guide, and the consequences of missing them are covered in our piece on retail routing guides and chargebacks.
The electronic paperwork runs in parallel
Larger accounts expect the shipment to be accompanied by electronic documents that arrive before the truck does: a purchase order that flows into the warehouse without being retyped, an advance ship notice sent when the shipment leaves telling the receiver what is coming and packed how, and an invoice matched against the purchase order and the receipt.
The value of the advance notice is that it lets the receiving facility plan labor before your freight arrives. A shipment without one may sit in a yard while someone works out what it is. The paperwork is not bureaucracy — it is what buys your freight a place in someone else's schedule.
Leaving the building is the biggest change
This is where B2B diverges most sharply from parcel. A consumer order is handed to a carrier that arrives daily and takes whatever is ready. Freight does not work that way.
Less-than-truckload (LTL) moves your pallets alongside other shippers' freight, transferring between terminals along the way. It is the normal choice for one to six pallets, and more transfers mean more handling — exactly why pallet construction matters.
Full truckload dedicates a trailer to your freight. It typically makes sense once you are shipping enough pallets to fill meaningful trailer space, and involves fewer touches because the load stays put.
Both require things parcel never asked of you: a bill of lading created before pickup listing piece count, weight and freight classification; an accurate freight class derived largely from density, where guessing leads to a reweigh and a corrected invoice; and a pickup appointment, often with a delivery appointment at the receiving end. Many distribution centers will not accept freight without a scheduled slot, and missing one can mean waiting for the next opening. Similar dynamics apply on the inbound side, explored in dock scheduling and inbound appointments.
The appointment is worth emphasizing, because it is the deadline that actually governs a B2B order. Not the day it was picked — the day the receiver agreed to take it.
Running both order types in one building
Most growing brands do not replace DTC with wholesale; they run both from the same inventory. That works, with three deliberate decisions: reserve stock against wholesale commitments so a large purchase order does not quietly consume what your online store is still selling; keep case and pallet picking out of the same aisles and hours as parcel picking, since they use different equipment; and set aside floor space near a dock where built pallets wait for a scheduled pickup, before the first order rather than on the day.
The short version
B2B fulfillment is not parcel fulfillment scaled up. It picks in cases and pallets, labels at three levels, sends its paperwork ahead of the freight, and departs on someone else's appointment calendar. Each is learnable, but each is a real change in how the warehouse works.
If wholesale accounts are on your roadmap, walk through your case configuration, labeling requirements, and freight plan before the first purchase order rather than after the first deduction. Our B2B fulfillment team works through exactly that with brands making the move.
