An online order and a retailer purchase order can draw from the same shelf and still need different fulfillment instructions. B2B fulfillment ships orders to business customers. When that customer is a retailer, the work must also fit its receiving process: purchase-order references, agreed quantities, packing instructions, shipment records, and delivery arrangements.
For a Canadian brand adding retail accounts, the practical question is how those requirements change the warehouse’s everyday work. Start with one order and follow it through to receipt.
B2B Fulfillment Versus Consumer Orders
Consider an illustrative example: a housewares brand holds inventory in a Toronto warehouse. A retailer orders 40 cases containing 12 units each, or 480 units, for an Ontario distribution centre. The brand also sells the same item through its online store.
A consumer buying two units creates a straightforward picking instruction: retrieve two items, pack them for that customer, and ship to their address. The retailer’s order starts with the same inventory but needs a different set of instructions for the receiving destination.
| Part of the order | Ordinary direct-to-consumer order | Retailer purchase order |
|---|---|---|
| Order reference | Online order and recipient details | PO, retailer item references and designated receiving location |
| Picking quantity | Items purchased by that consumer | Ordered units or cases, with the case conversion made explicit |
| Packing | Protection and presentation for the recipient | Carton or pallet preparation aligned with the retailer’s instructions |
| Shipping handoff | Dispatch through the selected delivery service | Applicable routing, shipment records and receiving arrangements |
| Follow-up | Delivery questions or a consumer return | Reconciliation of the PO, shipped quantities and retailer receipt |
The familiar work of ecommerce fulfillment, including order processing and shipping, remains part of both flows. For retail orders, the scope of warehouse fulfillment services also has to cover the buyer’s receiving requirements.
Order size alone does not define the channel. A retailer order can travel as parcels, while a consumer order can contain several items or require freight. The main difference lies in how the receiving destination expects the order to be prepared and documented.
Read the Purchase Order in Units and Cases
The first warehouse decision is what the PO quantity means. In the example, picking “40” individual units would leave most of the 480-unit order unfilled. The supplier’s SKU, the retailer’s item reference, and the units packed in each case need to describe the same product configuration.
Translate the order into a warehouse instruction that states 40 cases × 12 units = 480 units, alongside the PO number and destination. Keep the ordered quantity and the quantity actually released for picking as separate fields. That distinction becomes useful as soon as something changes. Retailer packing records can require both ordered and shipped quantities.
Next, decide which inventory is committed. If retail and online orders share stock, a reservation for the retailer must be reflected in the quantity still available to other orders. Alternatively, the business may dedicate stock to the retail channel. Shared stock offers flexibility; dedicated stock makes the allocation visible but leaves fewer units available for other sales. The right arrangement depends on the brand’s commitments to each channel.
This is where storage and inventory management connect to outbound execution. In a 3PL warehousing arrangement, the supplier and warehouse need an agreed way to distinguish physical stock from stock already committed to orders.
Suppose only 36 complete cases are ready. That is 432 units, leaving a 48-unit shortfall. Resolve whether the order will wait, ship partially or change before releasing it. Where the retailer requires approval, the supplier’s account owner should secure it and pass the resulting instruction to the warehouse. The packing team needs that decision before preparing the order.
Pack for the Receiving Team
Retail fulfillment has two packing jobs: protect the goods and make the shipment understandable at receipt. The receiver needs to connect the cartons in front of them with the order they expect.
For the 40-case example, the warehouse needs the agreed case contents, any rules for separating items or POs, and the required carton or pallet arrangement. If the order is palletized, its preparation instructions also need to cover how cartons are grouped and identified. Pick-and-pack work therefore starts from the customer’s packing specifications, even when the stock itself is unchanged.
The identifying numbers serve different purposes. GS1 Canada’s identification standards distinguish a Global Trade Item Number (GTIN), which identifies a trade item, from a Serial Shipping Container Code (SSCC), which identifies a logistics unit such as a case, pallet or parcel.
An advance ship notice (ASN) sends order and shipment information electronically to the receiver ahead of the goods. Its value depends on arriving in advance and accurately describing the shipment.
For example, Sporting Life’s vendor manual requires an ASN before receipt, one PO per ASN, and each carton’s unique SSCC label to match its contents and the notice. These requirements are retailer-specific; another account may use a different process.
For our illustrative order, the final shipment record must describe what was packed and loaded. If an approved change reduces the shipment to 36 cases, sending records for 40 creates a discrepancy before the truck arrives. GS1’s shipping guidance connects the ASN to the actual loaded units.
The Delivery Window Changes the Transport Plan
In B2B distribution, warehouse preparation has to be coordinated with the retailer’s receiving schedule. A carrier pickup booking answers when freight leaves. A delivery appointment answers when the receiving facility expects it.
Check the retailer’s routing instructions for any required carrier or service before booking. Confirm who pays freight and who arranges the receiving appointment, then pass those responsibilities to the warehouse and carrier.
Include the route in the order brief: the warehouse origin, receiving address, shipment dimensions and weight, required dates, and who arranges transport. For the Toronto-to-Ontario example, the carrier plan must work with that destination’s receiving slot.
Work backwards from the agreed receiving date: allow for the carrier movement, warehouse preparation and any required shipment notice. Keep the shipping window and the receiving appointment distinct in the instructions. Assign responsibility for notifying the retailer as soon as a delay threatens the agreed receiving date.
Close the Order Against the Receipt
Delivery confirmation and received quantity answer different operational questions. The first records the transport event; the second shows how the retailer accounted for the goods.
GS1’s receiving guidance describes receipt checks that may cover shipment contents and damage, depending on the supplier-receiver agreement. A receiving advice can confirm the goods received or identify missing and damaged items.
Return to the 40-case example. If the warehouse recorded 40 cases shipped and the retailer recorded 39 received, the next task is to compare the dispatch record, transport documents and receiving exception. That comparison establishes which discrepancy needs investigation. It does not, by itself, identify who caused it.
Agree who collects those records and who contacts the buyer or carrier. The warehouse can supply picking and loading evidence; the supplier’s account team can handle the retailer discussion. Clear ownership keeps the receiving issue connected to the original PO, dispatch record, and delivery documents.
What to Send a 3PL Before the First Retail Order
To assess B2B fulfillment services, give the provider a representative order and the instructions that govern it. A 3PL warehouse can discuss the work much more precisely when it can see the proposed handoffs.
Prepare a compact operating brief:
- Order and destination: a sample PO, retailer account, ship-to facility, and expected order frequency.
- Product and stock data: item references, units per case, available quantities and the rule for reserving inventory across channels.
- Preparation instructions: case contents, carton or pallet configuration, labels and packing records required by that account.
- Shipment information: any required ASN or other notices, who creates them and when the final packed quantities become available.
- Transport arrangements: origin, shipment size, routing instructions, required dates and the owner of the receiving appointment.
- Exceptions: who approves shortages or substitutions, communicates delays, and reconciles the retailer’s receipt.
Where the business already uses a warehouse for consumer orders, identify which retail logistics tasks are additional and who will perform them.
