EDI that passes
certification first try.
Trading partner onboarding, 856 ASN setup, 940/945 warehouse flows, and rejected file fixes — built by people who understand both EDI specs and how warehouse systems actually work.
How EDI projects actually fail
Your 856 was rejected. Again.
The MAN segment is there, but the SSCC format doesn't match what the trading partner expects. Or the pack/ship hierarchy is flat when the retailer requires a multi-level structure. Or the PRO number is in the wrong field. Each rejection adds a day. Most rejections are repeating the same mapping mistake.
Trading partner onboarding has been 'in testing' for a month.
The certification process works like this: you send a test file, the partner comes back with a list of errors, you fix them, resend, wait a week for review, repeat. Without someone who knows their specific requirements — and has done this before — every cycle costs another week and another delay to go-live.
The WMS shipped it. The 945 never left.
The shipment closed in Infoplus or Extensiv. The 945 Warehouse Shipping Advice should have gone out automatically. It didn't. Now the 3PL client is getting chargebacks for late ASN because their EDI provider never received confirmation that the order shipped. The disconnect between WMS events and EDI triggers is where most 940/945 flows break.
EDI documents we implement
Every document, every direction — mapped correctly to your specific trading partner requirements, not a generic template.
Purchase Order
Retailer sends a PO to your system. We map all required fields — line items, quantities, UOM, ship-to addresses, special instructions — into your WMS or order management flow.
- Buyer/supplier identification
- Line item & quantity mapping
- Ship-to & bill-to addresses
- Special handling codes
PO Acknowledgment
Confirmation that the PO was received and accepted. Some partners require line-level acknowledgment with accept/reject/change status per item. Missing or malformed 855s often trigger automatic chargebacks.
- Full / partial acceptance
- Line-level status codes
- Substitution handling
- Timing requirements
Advance Ship Notice (ASN)
The most complex and most-rejected EDI document. Multi-level hierarchy (shipment → order → pack → item), SSCC barcode in MAN segments, SCAC codes, carrier PRO numbers, GS1 compliance. We build and validate this correctly the first time.
- Multi-level pack/ship hierarchy
- SSCC / MAN segment setup
- SCAC & carrier data mapping
- GS1-128 label compliance
Invoice
Billing document sent to the buyer after shipment. Must reference the original PO and shipment. Mismatched line items, wrong UOM, or incorrect allowances/charges cause immediate rejections and payment delays.
- PO / shipment reference
- Line item reconciliation
- Allowances & charges
- Tax and discount handling
Warehouse Shipping Order
Sent by the 3PL client to instruct the warehouse to ship an order. This is the inbound trigger that creates a shipment in the WMS. Mapping errors here mean orders don't get created — or get created wrong.
- Order creation trigger
- Carrier & service mapping
- Line item & UOM handling
- Special instruction fields
Warehouse Shipping Advice
Sent by the warehouse after shipment confirming what was picked, packed, and shipped. Must match what the WMS actually processed. Timing and accuracy here directly affects your clients' ASN compliance with their retailers.
- Post-ship confirmation
- Actual vs ordered quantity
- Tracking & carrier data
- WMS event trigger setup
Functional Acknowledgment
Confirms receipt of any EDI transmission. Missing 997s are often the first sign that a transmission failed silently. We set up 997 monitoring so you know when the other side never got your file.
- Transmission confirmation
- Rejection code handling
- Silent failure detection
- Monitoring setup
Inventory Inquiry / Advice
Used to share available inventory with trading partners or clients. Requires accurate real-time data from your WMS. Often used for dropship programs and vendor-managed inventory.
- Available quantity export
- WMS inventory pull
- Scheduled transmission
- Multi-location support
Full-scope EDI work
From a first trading partner setup to fixing a broken 856 that's been rejected three times — we cover every part of EDI operations.
New Trading Partner Setup
End-to-end EDI setup for a new retailer, marketplace, or 3PL client. We review their implementation guide, map every required field, build the connection in your EDI provider, and manage the certification process from first test file to approved go-live.
- Implementation guide review
- Full field mapping build
- EDI provider configuration
- Certification management
ASN Configuration & Validation
The 856 is where most EDI projects fail. We build the correct pack/ship hierarchy, configure SSCC generation and MAN segment formatting, map SCAC codes to your carrier setup, and validate the output against the partner's spec before it ever gets submitted for testing.
- Multi-level hierarchy setup
- SSCC / MAN segment config
- SCAC & carrier mapping
- Spec-accurate validation
Warehouse Order Flow (940/945)
The 940 → WMS → 945 flow is the operational backbone of 3PL EDI. We build the inbound 940 trigger that creates orders in your WMS, and the outbound 945 that fires automatically when a shipment closes — with correct quantities, tracking, and carrier data.
- 940 inbound order trigger
- WMS shipment event mapping
- 945 auto-send on close
- Quantity & tracking accuracy
WMS & EDI Provider Integration
We connect your WMS — Infoplus, Extensiv, Logiwa — to your EDI provider — TrueCommerce, SPS Commerce, Orderful, Cleo — so data flows automatically. No manual exports, no copy-paste between systems, no missed transmissions.
- Infoplus / Extensiv / Logiwa
- TrueCommerce / SPS / Orderful
- Automated trigger setup
- Bidirectional data flow
Rejected File Diagnosis & Fix
Trading partner sends back a rejection with a vague error code. We identify the exact field, segment, or structural issue, fix the mapping, and resubmit — usually same day. We also find the root cause so the same rejection doesn't repeat.
- Error code interpretation
- Segment-level diagnosis
- Same-day mapping fix
- Root cause resolution
Data Mapping & Transformation
Every trading partner has slightly different requirements — different field lengths, different code sets, different hierarchy structures. We build transformation logic that correctly converts your source data into exactly what each partner expects.
- Field-level mapping docs
- Code set translation
- Conditional logic rules
- Multi-partner variance handling
Testing & Certification
We manage the full certification cycle with trading partners — submitting test files, interpreting feedback, making corrections, and coordinating until the partner gives production approval. We've done this with major retailers including Walmart, Target, Amazon, Costco, and Home Depot.
- Test file preparation
- Partner feedback resolution
- Certification coordination
- Production go-live sign-off
EDI Monitoring & Error Handling
We set up monitoring for 997 acknowledgments, transmission failures, and rejected documents so EDI errors are visible — not discovered three days later when a client asks why their shipment wasn't confirmed.
- 997 ack monitoring
- Rejection alerting
- Transmission failure detection
- Error escalation workflow
What happens when
EDI is done right
These are outcomes from real EDI projects — not test environments. EDI errors that repeat every cycle stop when you fix the root mapping, not the symptom.
Audit your EDI setupVs. 4–6 weeks when certification cycles repeat due to mapping errors.
After fixing 945 automation — shipment closes in WMS, 945 goes out same minute.
Inbound orders and outbound confirmations running without manual intervention.
Most rejected 856s diagnosed and corrected within hours, not the next certification cycle.
Read the spec.
Build it right.
Review the implementation guide — all of it
Every trading partner publishes an EDI implementation guide. Most people skim it. We read it in full: required vs optional segments, code set requirements, hierarchy expectations, timing rules, and the 'gotchas' buried in the footnotes. That's where certifications fail.
Map every field from source to EDI
We document exactly where every required EDI field comes from in your WMS or source system — order data, shipment data, package data, carrier data. Fields that don't exist get flagged early, not discovered during testing.
Build, validate, then test with the partner
We build the mapping in your EDI provider, generate test files, and validate them against the spec before submitting. The goal is to submit a passing first test file — not to start a 10-round correction cycle.
Automate the flow and monitor it
After certification, we make sure every document triggers automatically from the right system event — and that failures are visible. An EDI flow that requires manual checks isn't actually automated.
EDI and WMS expertise in one place.
Most EDI consultants don't know what a 945 triggers in Infoplus. Most WMS consultants don't know why an SSCC fails MAN segment validation. We know both sides — which is why our integrations don't need three rounds of testing to pass.
EDI + WMS — not one or the other
The 940/945 workflow only works when the WMS and EDI sides are configured together. We understand both — Infoplus and Extensiv shipment events, and what those events need to generate in TrueCommerce or SPS Commerce.
Partner-specific, not generic
Walmart's 856 requirements are not the same as Target's. We build to the actual implementation guide — not a generic template. That's the difference between a first-pass certification and a month of rejection cycles.
Same-day rejection fixes
When a trading partner rejects a file, the error code is usually vague. We identify the exact segment, field, and mapping issue within hours — and submit a corrected file the same day.
Automation, not just setup
EDI isn't done when the first file goes through. We build the triggers, automate the flows, set up monitoring, and make sure your team isn't manually initiating transmissions or checking for failures.
Common questions
What EDI providers do you work with?
We work with TrueCommerce, SPS Commerce, Orderful, Cleo, DiCentral, and others. We're not tied to a specific platform — we work in whatever EDI provider is already in your stack or help you select one if you're starting fresh.
What WMS systems do you integrate with for EDI?
Our primary WMS expertise is Infoplus and Extensiv (3PL Central / 3PL Warehouse Manager). We also work with Logiwa and other systems. The critical piece is connecting the WMS shipment events to the correct EDI outbound triggers.
Can you handle a specific retailer's requirements?
Yes. Every major retailer — Walmart, Target, Amazon Vendor Central, Costco, Home Depot, Wayfair — has their own implementation guide and specific requirements. We've worked through certification with all of them. Bring us the spec and we'll build to it.
We're already getting EDI rejections. Can you help?
This is most of what we do. Send us the rejection notice and the file. We identify the segment and field causing the error, fix the mapping, and resubmit — usually same day. We also find the underlying configuration issue so it doesn't repeat.
How long does a new trading partner integration take?
A standard 850/856/810 setup with a major retailer takes 1–2 weeks from spec review to certified go-live — assuming your source data is clean. The 940/945 warehouse flow is typically 3–5 days if the WMS connection is already in place.
What if we have multiple trading partners with different requirements?
Normal. We maintain separate mapping profiles per partner and build transformation logic that handles the variance. Each partner gets exactly what their spec requires, even when the source data is the same.
