The Walmart routing guide, errors caught before the carton ships.
For brands and 3PLs shipping into Walmart, Packit turns Walmart's supplier requirements into a guided packing checklist and AI-checks every label and ASN step at the pack station, so OTIF and SQEP problems get caught while the carton is still open and a worker can still fix it.
Stop hand-checking the supplier guide and discovering mistakes weeks later as an OTIF fine or SQEP defect. Packit catches the wrong label, the missed ASN field, the bad carton config at pack time, the moment it's still fixable.
Compliance for Walmart suppliers

Label specs, ASN timing windows, OTIF and SQEP traps, carton/pallet config, and more, specific to Walmart or any other trading partner.
Routing guide compliance, enforced at the pack station.
Stop hand-checking 200-page PDFs
Walmart's supplier requirements become a structured, repeatable packing workflow — the rules live inside the checklist, not in a binder or one veteran's memory.
Catch errors before they ship
Every order is auto-matched to Walmart's specific requirements, so the right rules apply to the right carton every time.
Eliminate packer guesswork
Step-by-step checklists with photo capture at every shipment. New hires get up to speed fast because correctness is system-enforced, not supervisor-dependent.
Compliant labels, every time
GS1-128 labels and ASN data flow in from your EDI platform (Crstl or any other) and Packit verifies them at the pack station before the box is sealed.
What Walmart's supplier requirements actually ask for.
Walmart is the largest retailer in the world, and its supplier requirements are among the most strictly enforced. The routing guide and supplier standards govern how product is labeled, packed, documented, and delivered into Walmart's distribution centers and stores. Walmart doesn't just ask for compliance — it scores it, through On-Time In-Full (OTIF) and the Supplier Quality Excellence Program (SQEP), and every miss carries a fine. By the time a deduction lands in Retail Link, the shipment is long gone and the error is unfixable.
The four things every Walmart shipment has to get right
- Carton and pallet labeling. GS1-128 (formerly UCC-128) shipping labels with the correct SSCC structure, placed and oriented to spec. Walmart DCs scan on receipt; an unreadable, mis-placed, or wrong label is a SQEP defect — and a per-carton charge.
- Advance Ship Notice (ASN) accuracy. The 856 has to transmit on time and match what's physically on the trailer, down to the carton. ASN errors are one of the most common and most heavily penalized SQEP defect types.
- On-Time In-Full (OTIF). Ship the full quantity, in the delivery window, to the right place. Walmart measures both on-time and in-full performance against a target and fines a percentage of cost of goods on shipments that miss.
- Routing and transportation. Depending on whether you're a prepaid or collect supplier, you route through Walmart's transportation process and load/MABD (Must Arrive By Date) windows — you don't pick your own carrier or arrival date.
What's unique is the specific tolerances, label placement, ASN timing, and OTIF windows in Walmart's standards. That's exactly what Packit encodes into the packing checklist — so the requirement is enforced at the moment the worker is packing, not buried in a guide nobody re-reads.
AI photo verification, inline as you pack.
As workers pack, they photograph the key compliance steps, like a GS1-128 label on the front face of a carton. Packit checks each photo against Walmart's specific criteria — correct placement, scannable barcode, unobscured, within margins — and returns one of four results in seconds:
The step meets Walmart's spec. The worker keeps moving — no stoppage, no lookup.
A confirmed failure on a critical step blocks submission until it's fixed or a supervisor overrides — so the carton can't ship into a SQEP defect.
Ambiguous cases don't punish the worker the way a real mistake does. The line keeps moving.
A technical glitch is treated as a glitch, not a failure — so workers are never penalized for it.
The result: a worker who labels a carton wrong gets immediate feedback to correct it before the carton is sealed, rather than discovering the problem weeks later in a chargeback notice. Correctness becomes system-enforced rather than supervisor-dependent, which is what makes it hold up across every partner and every new hire.
The traps Packit catches at pack time.
These are the compliance failures that turn into Walmart OTIF fines and SQEP defects most often. With Packit, each one is a checklist step verified before the carton is sealed, caught while it's still fixable, not weeks later as a deduction in Retail Link.
Built to connect to whatever you already run.
Packit isn't an island, and it doesn't replace your systems. It has a source-agnostic ingest layer: any external system — an ERP, a WMS, or an EDI platform, whether that's Crstl or another provider — can push purchase orders, labels, and ASN data straight into Packit through authenticated API calls. Admins create and manage their own API keys and permissions right in the Packit UI, with no engineering ticket required.
That removes one of the oldest sources of warehouse error: people re-keying order data by hand and introducing the very transcription mistakes that trigger chargebacks. When PO data flows in automatically, packers see accurate, current order information the moment it lands — and Packit verifies the physical work against it at the station.
Order in, verified, packed, ASN confirmed
An order arrives, a packing session begins, the shipment is photo-verified against Walmart's requirements, and the ASN is confirmed, with no human stuck in the data-entry path and no compliance step left to memory. Partner compliance stops being a recurring penalty and becomes a solved, repeatable process. No middleware. No parallel stack. No IT ticket.
