EDI-Integrated B2B Fulfillment
Sell to Walmart, Target, Costco, and Amazon Vendor Central without chargebacks eating your margin. We handle every EDI document your retailers require — purchase orders (850), ship notices (856), invoices (810), and the rest — automatically, through SPS Commerce, TrueCommerce, or direct connections.
Walmart's purchase order lands directly in our warehouse system. No email chains, no re-typing.
The retailer gets instant confirmation the order is accepted and in the fulfillment queue.
Every carton labeled exactly the way that retailer's routing guide requires.
The ASN — the #1 cause of retailer chargebacks — is built from actual shipment scans and sent on time.
Billing mirrors what actually shipped, so you get paid on time with no short-pays.

Pre-built integrations with Walmart, Target, Costco, Amazon Vendor Central, Kroger, Meijer, Sam's Club, BJ's, and most regional retailers. Standard EDI onboarding takes 2-3 weeks. Typical client chargeback rate under 1%.
What Is EDI, In Plain English?
EDI (Electronic Data Interchange) is how big retailers exchange business paperwork with their vendors — computer to computer, instead of email and spreadsheets. Every document type has a number, but behind each number is a document you already know:
“Here’s what we want to buy.” The retailer’s order — what to ship, where, and by when.
“It’s on the truck.” A heads-up to the retailer with exactly what’s in every carton — sent before the truck arrives.
“Here’s the bill.” Matches the shipment line for line, so you get paid on time.
Retailers require these documents to be sent in an exact format, on an exact schedule — and they fine vendors (chargebacks) when anything is late or wrong. That's the entire reason EDI capability matters when choosing a 3PL: it's not a technical feature, it's margin protection.
Every EDI Document Your Retailer Requires
Full X12 v4010 and v5010 support — every standard retail vendor document, translated into what it actually means for your business.
Purchase Order
The retailer's order — what they want, where to ship it, and by when. Flows straight into our warehouse system with zero manual entry.
PO Acknowledgment
Our confirmation back to the retailer that the order is accepted — or a flag on problems before they become shipment failures.
Advance Shipping Notice (ASN)
The “it's on the truck” notice, with carton-level detail and tracking. Late or inaccurate ASNs are the #1 cause of retailer chargebacks.
Invoice
The bill for what shipped. It must match the ship notice exactly — mismatches mean delayed or shorted payments.
Warehouse Shipping Order
A shipping instruction to the warehouse: “ship these goods from inventory to this destination.”
Warehouse Stock Transfer Receipt
Our confirmation that your inbound product arrived — with received counts and condition.
Warehouse Shipping Advice
Our confirmation that an order shipped, carton by carton. This is what triggers your ASN and invoice automatically.
Inventory Adjustment Advice
Any inventory change — cycle counts, damage, corrections — reported to you so your numbers always match ours.
Price/Sales Catalog
A product catalog with pricing, shared in either direction, so buyers always order from accurate data.
We Connect However Your Retailers Require
Already have an EDI provider? We plug into it. Don't have one yet? We set it up and manage it for you — you never touch the technical side.
SPS Commerce
The most widely used EDI network — 100,000+ retailers. We have pre-built connections with retailer fulfillment maps ready to go. Typical setup: 2-3 weeks per retailer. Best fit for brands selling to multiple national chains.
TrueCommerce
Alternative EDI provider we connect to with pre-built integrations. A common choice for brands with significant Kroger, Wegmans, HEB, or specialty grocery volume.
Direct AS2 / SFTP
We connect straight to the retailer's systems without a network provider in between, which lowers per-order costs at higher volumes. Best fit for established, high-volume retail vendors.
No EDI Yet? We Set It Up.
If a retailer just approved you as a vendor and you don't have EDI at all, we set up the provider relationship, configure every document type, and pass through provider costs at-cost. You never touch the technical side.
Retailers We Ship To Over EDI
Pre-built integrations with major US retailers, plus active capability for regional chains, drug stores, and specialty retailers.
EDI Integration for Retail Vendors — What Matters
EDI (Electronic Data Interchange) is the system that runs retail B2B commerce. Walmart, Target, Costco, Kroger, and every major retailer requires EDI for purchase orders, shipping notices, invoices, and inventory updates. Without proper EDI integration, you can't be a retail vendor at scale.
The technical specs are well-documented — X12 transaction standards, retailer-specific routing guides, EDI VAN architecture. What separates good 3PL EDI from bad 3PL EDI isn't the technology. It's how the operational workflows around EDI prevent chargebacks.
The four EDI flows that matter most
For B2B retail vendor fulfillment, four EDI transactions drive most operational risk:
- 850Purchase Order — the retailer's order coming in. Must be read correctly, validated against inventory, and turned into a pick/pack workflow. Errors here cause shipment failures.
- 856ASN (Advance Shipping Notice) — the "it's on the truck" notice with carton-level detail (GS1-128 labels, pack contents, expected arrival). It must reach the retailer before the goods arrive at their dock — or chargebacks hit. This is where most chargeback exposure lives.
- 810Invoice — the bill for shipped goods. Must match the ASN exactly. Mismatches trigger payment delays or short-pays.
- 945Warehouse Shipping Advice — the warehouse's confirmation that an order actually shipped. It triggers the ASN and invoice, so it must come from real shipment events, not estimates.
Why chargebacks happen
Retailers charge vendors for compliance failures: late ASN transmission, inaccurate ASN data, wrong labels, missed shipping windows, OTIF failures, routing guide violations. Walmart's most common chargebacks include:
- Late ASN (transmitted after delivery) — typically 3% of invoice value
- Inaccurate ASN (count mismatch, wrong UPC) — 1-3% per occurrence
- Missing or incorrect GS1-128 labels — fixed fee per carton
- OTIF failure (late or short delivery) — typically 3% of invoice value
- Wrong routing (didn't follow routing guide) — varies
For a $1M annual vendor, a 3-5% chargeback rate equals $30K-$50K in lost margin. EDI competency is the difference between 0.5% chargeback rates and 5% chargeback rates.
Chargeback prevention workflow
Our EDI operations include built-in chargeback prevention:
- ASNs auto-generated from actual shipment scans, not estimates — eliminates count mismatches
- Pre-shipment validation against retailer routing guides catches errors before truck leaves dock
- Label generation from retailer-specific templates with current version control
- Shipping cutoff enforcement to meet retailer transmission windows
- Dedicated retail compliance team monitoring scorecards weekly
- Proactive escalation when KPIs trend negative before chargebacks hit
When to add a new retailer
Adding a new retailer EDI integration typically requires 2-4 weeks: trading partner profile setup with the EDI VAN (1 week), routing guide review and label template configuration (1 week), QA environment testing of full transaction flow (1 week), and production cutover with parallel monitoring (1 week). New or unusual retailers may take 4-6 weeks.
For brands planning multi-retailer rollout, we recommend starting with one retailer, stabilizing operations, then adding the next. Concurrent multi-retailer onboarding increases risk of operational issues affecting all retailers simultaneously.
