Independent EDI conversion and validation software. Retailer names identify interoperability targets; no retailer endorsement is implied.
Shipment Sentry
Multi-retailer shipment gateway

One source file in. The right retailer file out.

Turn CSV, Excel, XML, JSON, IDoc, PDF, images or existing EDI into validated partner output. Confirm each new layout once, then route mixed batches of up to 1,000 files by partner code over SFTP, email or API.

No retailer guessing

Every document carries an explicit partner code

Confirm once

Saved source signatures make repeat layouts automatic

Fail one, not all

Every batch returns an independent result per file

Warehouse dispatch desk with a labelled carton, shipment manifest, barcode scanner and orange exception tag
Document ↔ label ↔ physical carton

Three decisions before a file leaves.

Source analysis, partner rendering and output validation share one deterministic path across the website, SFTP, email and API.

  1. 01 / MAP

    Can source fields become shipment truth?

    Inspect headings and values, propose a mapping, and require confirmation before the first automated release.

  2. 02 / ROUTE

    Which partner pack owns this output?

    Resolve the explicit code inside the workspace and render X12 856, EDIFACT DESADV or Amazon shipment JSON.

  3. 03 / VERIFY

    Is the generated file safe to return?

    Validate the generated output immediately, isolate failures, and return a per-file receipt and traceable rule-pack version.

Drop 1,000 files. Route 1,000 decisions.

A bad Target file does not block a valid Walmart file. Missing codes and first-seen source layouts move to quarantine; confirmed siblings keep processing and receive their partner output.

SFTP

Partner folders or filenames

/inbound/documents/WALMART-US/asn.csv

Receive outputs under the same partner code with cleared, blocked and quarantine lanes plus a batch manifest.

Email

Tagged recipient or attachment

workspace+AMAZON@in.shipmentsentry.com

Authorize exact senders. Route attachments by plus tag or PARTNER__filename; large result sets return as one safe ZIP.

API + callback

Code on every document

"partner_code": "TESCO-UK"

Idempotent batch responses include every decision; optional signed callbacks report completion without exposing document payloads.

Partner truth stays explicit: Amazon and Walmart packs have public first-party implementation evidence. Other retailer routes apply universal X12 or EDIFACT controls and remain marked “partner guide required” until your current authorized guide is configured.

Every guide ends in a check you can run.

No keyword wallpaper. Indexed pages have a distinct rule, current source trail, accepted/rejected examples, and a relevant tool.

Implementation guide

EDI 855 validation starts with the active 850
