In retail, the warehouse is where margin leaks. Chargebacks are a fulfillment execution problem billed to the brand, so the operation and the contract have to be scoped together.
A retail or CPG requirement is not primarily a storage requirement. It is a compliance requirement with storage attached. Every retailer publishes a routing guide, updates it without much warning, and measures adherence per shipment. When a shipment breaks a rule, the retailer deducts against the vendor invoice, and the vendor of record is the brand, not the warehouse that made the error.
That is the structural problem worth solving in the contract. By default the brand absorbs a chargeback caused by a mislabeled carton or a late advance ship notice. Unless the agreement explicitly assigns liability for provider-caused compliance failures, defines the categories, requires root-cause documentation, and sets a remedy, the operator has no financial stake in the accuracy of its own labels.
The recurring causes are documentation and timing rather than damaged freight: advance ship notices transmitted late or carrying detail that does not match the physical shipment, label format and placement errors, pallet configurations outside specification, missed delivery appointments, and carton counts that disagree with the ASN. All of them originate on the warehouse floor or in the warehouse system, which is why the routing guide has to be configured into the operation rather than forwarded to an account manager.
These are warehouse-executed, retailer-measured, and brand-billed. Each is a line item to specify in the requirement and a question to test at the site visit.
At minimum the 850 purchase order inbound, the 856 advance ship notice outbound with accurate pallet and carton level detail, and the 810 invoice. Operations running through a 4PL or ERP layer also need the 940 warehouse shipping order and 945 shipping advice. Ask whether EDI is native to the warehouse system or bolted on through a third-party value added network, and who pays per-document fees, because they add up at wholesale volume.
Most routing guides require the advance ship notice to transmit before arrival, often inside a defined window after the truck departs. A late ASN is a chargeback even when the freight is perfect. Specify the transmission window and require exception alerting when a shipment leaves without one.
GS1-128 shipping container labels with the required data elements, correct symbology, and correct physical placement on the carton and the pallet. Placement errors are as common as data errors and cost the same.
Retailer-specified tie and high, maximum pallet height, overhang rules, wrap specification, slip sheet use, and rules for mixed-SKU pallets. Warehouse staff build to a standard; if that standard is not the retailer standard, every shipment is non-compliant.
Booking lead time, the portal it runs through, and how tight the arrival window is once confirmed. Missed and rescheduled appointments are a high-frequency deduction category and a source of on-time-in-full failure that has nothing to do with the pick.
A contract clause defining which deduction categories count as provider-caused, requiring documented root cause on each one, and setting a remedy. Also require monthly chargeback reporting by category so the trend is visible before it becomes an argument.
Retail programs price mostly on handling and outbound rather than storage, because the inventory turns. National bands across the profiled Canadian markets, current as of Q2 2026:
| Line item | 2026 range | Unit |
|---|---|---|
| Ambient pallet storage | $12 – $40 | per pallet / month |
| Pallet handling, in or out | $7 – $20 | per pallet, per move |
| Pick, pack and ship, first unit | $2.50 – $7.00 | per order |
| Container destuff | $325 – $700 | per 40 ft container |
| Trailer parking, secured yard | $125 – $450 | per 53 ft trailer / month |
Warehouse Bridge network data, current as of Q2 2026. EDI per-document fees, display building, and rework are quoted per program and belong in the rate comparison alongside these lines. Full city-by-city tables are in the Canadian Warehouse Market Report, and the 3PL cost calculator models a market-specific figure.
Ask these in the RFP rather than at the site visit. The answers narrow a shortlist faster than any rate comparison, and they are all verifiable.
Which of my retailers do you ship into today, and at what volume?
Production experience with a specific routing guide, or a learning curve paid for with your deductions.
What is your chargeback rate into those accounts over the last twelve months?
A measured number, a stated denominator, and a trend. Or nothing, which is its own answer.
What is your process when a routing guide changes?
Who monitors it, who reconfigures the system, and how the floor gets told before the next shipment goes out.
How quickly does the 856 transmit after the truck departs?
Late ASNs are the most preventable deduction category. The answer should be a number of minutes or hours, not a description of the process.
Is EDI native to your warehouse system?
A translation layer between the WMS and the retailer adds a failure point and a per-document cost. Both belong in the quote.
Routing guides, ASN timing, label placement, and who pays when compliance fails.
A worked requirement for a wholesale program, with the compliance sections filled in.
Peak capacity commitments, labour ramp, and the timeline for securing overflow space.
Node placement against retail distribution centres and delivery windows.
Procurement templates: the 3PL RFP template puts the compliance questions above into a requirements sheet vendors respond to line by line.
A routing guide is the retailer's rulebook for how vendor shipments must arrive: which carrier to use and who pays, how delivery appointments are booked, label format and placement, pallet height and configuration, carton marking, and the electronic documents that must accompany the shipment. Every major retailer publishes its own and revises it without much notice. Compliance is measured per shipment and violations are billed back to the vendor as chargebacks against the invoice.
By default the brand pays, because the deduction is taken from the vendor's invoice and the vendor of record is the brand. Unless the 3PL agreement explicitly assigns liability for compliance failures caused by the provider, the brand absorbs the cost of a mislabeled carton or a late advance ship notice even when the warehouse made the error. Defining the provider-caused categories, requiring documented root cause, and setting a remedy is one of the most valuable clauses to negotiate in a B2B fulfillment agreement.
At minimum the 850 purchase order inbound, the 856 advance ship notice outbound with accurate pallet and carton level detail, and the 810 invoice. Programs running through a 4PL or an ERP layer also need the 940 warehouse shipping order and the 945 warehouse shipping advice. The questions that matter beyond the list are whether EDI is native to the warehouse system or bolted on through a third-party network, how quickly the 856 transmits after departure, and who pays the per-document fees.
Three questions, each requiring evidence. Which retailers do you ship into today, by name. What is your chargeback rate as a percentage of shipments into those accounts. Show me what happens when a routing guide changes. A provider already shipping into your retail customers has already absorbed those routing guides at their own cost, which is worth more than any stated capability, and a provider that cannot quote a chargeback rate is not measuring one.
Yes, and for many CPG brands a shared inventory pool is the point, because it avoids splitting stock between channels and stranding units on the wrong side. The requirement is to price the two flows separately. Pallet-out wholesale and single-unit parcel picking have different pick paths, labour profiles, packaging consumption, and peak curves, so a blended number hides which channel is subsidising the other and makes the eventual rate review impossible to argue.
Warehouse Bridge operates no warehouse of its own. There is no building we need to fill, so the operator that fits the specification wins the work. For a retail & cpg requirement, the useful first conversation is about licence scope, compliance profile, and volume, before any building is on the table.
Call (289) 907-3794 or email solutions@warehousebridge.ca. Program structures and thresholds are set out on the enterprise page.
