Service detail
EDI-native retail compliance, GS1-128 labels printed at the case, ASNs that arrive before the trailer, and palletized LTL builds that match the routing guide. We ship to roughly 40 retailer destinations a week without chargebacks being a line item on the invoice.
TL;DR
The naive view of wholesale fulfillment is that a B2B order is just a bigger DTC order. Pick more units, build a pallet instead of a parcel, ship LTL instead of UPS Ground. In reality, B2B is harder. The customer is not a person with a Shopify cart. The customer is a retailer with a 200-page routing guide, a one-hour ASN window, and a fine schedule that turns small mistakes into meaningful invoice deductions.
Walmart, Target, Costco, Whole Foods, Kroger, Home Depot, Lowes, and the national grocery banners each publish their own EDI specifications, label requirements, palletization rules, appointment-scheduling protocols, and penalty matrices. The 856 ASN that works perfectly for Walmart will fail validation at Target because of different field requirements or timing windows.[3]A pack-list that is fine for Whole Foods will draw a chargeback at Kroger.
The economics are unforgiving. Walmart's OTIF program penalizes suppliers 3 percent of cost-of-goods on cases that miss the on-time or in-full window.[1]Target's ASN availability is charged at $0.75 per carton with a $100 minimum; Target's ASN accuracy is charged at the same rate again. A single trailer with 400 cartons and an ASN error can hit a $300 fine before anyone has unloaded a pallet. Stack a few of those across a quarter and the wholesale margin disappears.
EDI is the language of B2B fulfillment, and most retail mandates require it. Walmart, for example, requires every supplier to be EDI-capable; there is no manual alternative for ongoing business.[6] The handful of transaction sets that move the bulk of wholesale activity are listed below.
Core EDI documents in a wholesale fulfillment cycle
| Doc | Direction | Purpose | Why it matters |
|---|---|---|---|
| EDI 850 | Inbound | Purchase order from the retailer | Triggers the order in the WMS |
| EDI 855 | Outbound | PO acknowledgment back to retailer | Confirms acceptance, quantity, and ship date |
| EDI 856 | Outbound | Advance Ship Notice (ASN) | Tells the retailer what is on the trailer before it arrives |
| EDI 810 | Outbound | Invoice | Triggers payment per the retailer's payment terms |
| EDI 940 | Inbound (3PL) | Warehouse shipping order | Used in client-to-3PL flows |
| EDI 945 | Outbound (3PL) | Warehouse shipping advice | 3PL confirms shipment back to client |
The EDI 856 ASN is the single most compliance-sensitive document in the cycle. Industry data is consistent: more chargebacks originate from 856 failures than from any other EDI document.[3] The ASN must arrive in the retailer's system before the physical goods land at the receiving dock. If the trailer beats the ASN, the cartons are flagged for manual processing and the supplier eats the chargeback.
The pack-line workflow blocks the trailer-seal step until the ASN has transmitted and received an acknowledgment. Practically, this means the operator scans the last carton onto the pallet, the WMS triggers the 856 build, the SPS or TrueCommerce VAN transmits, and the dock supervisor sees a green status before authorizing the seal. If the ASN fails validation, the trailer waits.
For Target specifically, we run the pack waves to close in the morning so the 60-minute ASN deadline lands inside business hours, with operations supervision available to react if the VAN throws an error.[2] A late-afternoon trailer close on a Friday is the riskiest possible window; we do not schedule Target outbound that way.
A GS1-128 carton label encodes the structured shipping data the retailer needs to reconcile a delivery against an ASN. The barcode carries an SSCC-18 serial shipping container code, purchase order number, ship-to location, dates, quantities, and any retailer-specific application identifiers. Each carton on a pallet has its own SSCC; the pallet itself can carry a pallet-level SSCC if the retailer's routing guide requires one.
The mistake new shippers make is treating GS1-128 as a generic format. It is not. While the zone structure is standardized, the specific data fields, positions, and barcode configurations required vary by retailer. A label built for Walmart will not work for Target or Kroger.[7] Our label templates live in the WMS as retailer-specific assets; the operator never touches a label design.
“The cleanest way to get GS1-128 right is to build the label at the case pack station, not at the dock. Print, apply, scan, verify the SSCC matches the WMS record, then move on. If the verify scan fails, the carton does not enter the pallet build queue.”
Physical print quality is also enforced. Most retailers run an ANSI grade C minimum on barcode quality, and barcodes that fail to scan generate $0.75-per-defective-carton chargebacks under perfect-order programs.[7]Thermal printer maintenance, ribbon quality, and label stock specification all feed into print grade. Our case-pack stations run Zebra industrial printers with quarterly grade audits.
Each retailer's routing guide specifies pallet height, overhang allowance, stretch-wrap turns, slip-sheet rules, and trailer-load patterns. Walmart, for example, has explicit rules around CHEP vs. white-wood pallet usage, pallet weight maximums, and how mixed-SKU pallets are labeled. We pre-load the build instructions per retailer and per ship-to RDC so the operator on the floor works to a printed pick ticket that matches the routing guide rather than guessing.
Pallet build defaults by retailer (illustrative; check current routing guide)
| Retailer | Pallet type | Max height | Max weight | Mixed SKU |
|---|---|---|---|---|
| Walmart RDC | GMA / CHEP | 70 in | 2,200 lb | Layer-segregated |
| Target RDC | CHEP | 76 in | 2,500 lb | Allowed with pallet ASN |
| Costco DC | Block-stack | 60 in | 2,200 lb | Single SKU per pallet |
| Kroger DC | GMA | 72 in | 2,500 lb | Layer-segregated |
| Whole Foods DC | GMA | 60 in | 1,800 lb | Allowed |
| Amazon Vendor Central | GMA | 72 in | Per ASIN spec | Single ASIN per pallet |
Walmart OTIF is the program every wholesale supplier learns the hard way. The target is 98 percent on-time and 95 percent in-full at the case level, with a 3 percent fine on cost-of-goods for shipments outside the window.[1]For prepaid suppliers, the on-time metric runs at 90 percent of cases arriving within the delivery window at the DC; for collect, the metric is 98 percent.[1]In-full is calculated as cases received divided by cases ordered.
The on-time half of OTIF is mostly about getting the trailer to the right DC at the right appointment. The in-full half is about pick accuracy and inventory visibility. A wholesale order for 480 cases that ships 472 because eight cases were a pick miss is in-full at 98.3 percent on that PO, which sounds fine but is below the 98 threshold. Repeat across 50 POs in a month and the cost adds up.

The root causes of OTIF failures are usually upstream from the 3PL: late production, incorrect inventory at the manufacturer, freight broker missing pickup. We cannot ship cases we do not have. What we can do is run the pieces inside our four walls reliably enough that you never lose OTIF on a pack accuracy issue, an ASN error, or a missed appointment. Routing-guide appointment management is included in the base service for our B2B clients.
DSV is the hybrid model that sits between wholesale and DTC. The retailer lists your product on their site, the customer places the order on the retailer's domain, the order routes to your 3PL, and you ship a single parcel directly to the consumer under the retailer's brand promise. Walmart DSV is the largest of these programs in the US.
Walmart's DSV requirements are stricter than its standard wholesale terms in some areas. Suppliers must maintain a 99 percent on-time-ship rate at the facility, hold inventory at a level that produces no more than 0.1 percent backorders monthly, and meet specific carrier rate-card and packaging standards.[4] We run the DSV pick lane on the same operating discipline as our DTC operation, with a separate SLA dashboard so the 99 percent number is visible daily, not at month-end.
Most B2B outbound moves on LTL (less-than-truckload) freight to the retailer DC, with full-truckload reserved for higher volume routes. We work with a short-list of LTL carriers that have proven on-time performance to the major retailer DCs from Kansas City: Old Dominion, XPO, Saia, Estes, ABF, Yellow Logistics, R+L, and the carrier networks each retailer prefers.
Routing-guide compliance on freight is its own discipline. Walmart, for example, requires specific SCAC codes for collect shipments, mandates use of its Retail Link transportation portal for appointment scheduling, and audits pickup windows against the appointment grid. Missing the appointment window is an OTIF strike. We schedule appointments through Retail Link directly, with automated re-attempts if the slot is rejected.
“Freight is where small mistakes turn into large delays. A pallet built two inches over the height limit gets refused at the DC. A trailer arriving at the wrong appointment slot circles for hours. The fix is checklist discipline at the dock, not heroics.”
For high-volume retail accounts (more than 4-5 pallets per week to the same DC), we evaluate consolidator programs. A weekly milk-run from KC to a Walmart regional DC can shave LTL spend significantly versus on-demand bookings. The trade-off is rigidity: the consolidator runs on its own schedule, so your production and pack must keep up.
Bringing a new retailer online inside a 3PL is a project, not a button press. The work breaks into four phases: routing-guide ingestion, EDI mapping and test, label and pack-spec build, and a live test PO. The total elapsed time depends on the retailer; a clean Walmart prepaid program lands in three to five weeks, a complex Target Vendor Direct program can take eight.
Typical onboarding sequence per new retailer
| Phase | Duration | Deliverable |
|---|---|---|
| Routing-guide ingestion | Week 1 | Pack spec, label spec, palletization rules logged in WMS |
| EDI mapping & VAN test | Week 1-2 | 850/855/856/810 transactions tested through SPS/TC sandbox |
| Label template build | Week 2 | GS1-128 carton + pallet label tested with retailer barcode validation tool |
| Live test PO | Week 3-4 | Small pilot PO shipped, scorecard reviewed, fixes applied |
| Production | Week 4-5 | Full PO volume cleared to ship, monitoring dashboards live |
The single most useful artifact in the onboarding kit is the retailer's own routing guide PDF. We strip it for pack rules, palletization, ASN field requirements, label specs, and appointment-scheduling protocols. Anything ambiguous becomes a question for the retailer's vendor support before the first PO ships. We do not guess on routing-guide language.
Talk to retail compliance
Wholesale onboarding is built around your first scheduled PO date. The fastest Walmart onboarding in the last twelve months was three weeks from contract signature to first prepaid trailer. We do not start a Target program in parallel with the holidays.
