01 The problem

EDI hasn't changed since 1985. The vendors paying for it have.

If you sell into big-box retail, EDI is mandatory, brittle, and expensive. The incumbents charge you to feel that pain slowly.

6 wks

Manual spec-reading and map-building, billed as professional services — per retailer, per document.

A late ASN or a mislabeled carton turns into automatic deductions you find out about weeks later.

POs land in a portal, then someone retypes them into a spreadsheet. Errors flow straight to the floor.
02 How it works

Point HeddleGrid at a retailer's spec. It does the mapping.

The hard part of EDI was never the syntax — it's the partner-specific map. We hand that to AI, with a human approving the result.

STEP 01

Drop in the guide

Upload the retailer's EDI implementation guide and a few sample files. HeddleGrid reads every segment, qualifier, and code list.

STEP 02

AI drafts the map

HeddleGrid generates the full canonical mapping plus validation rules in hours, with fixtures from your real samples. Your analyst reviews and approves.

STEP 03

Go live, two-way

AS2 or SFTP, control numbers, 997s, resends — handled. Orders flow in as clean data; acks, ASNs and invoices flow back out automatically.

The full picture — a two-way loop

Once a partner is live, documents flow both directions automatically. You only ever touch clean data; HeddleGrid speaks EDI on both ends.

Inbound — orders come to you
1
Your partner transmits a purchase order (850) over AS2, SFTP, or their network.
2
HeddleGrid parses and validates the raw X12 — envelopes, control numbers, required segments.
3
It maps to your canonical Order using the approved partner mapping.
4
The clean order is delivered by webhook, API, or dashboard — and a 997 goes back automatically.
Outbound — you respond
1
You acknowledge, ship, or invoice — from the dashboard or your own systems via API.
2
HeddleGrid generates the compliant EDI — 855, 856, or 810 — from your canonical data.
3
It assigns control numbers and sends over the partner's connection.
4
The partner's acknowledgment is reconciled — you see exactly what landed and what didn't.

Map once — not once per partner

Every partner maps to one canonical model, so you build your integration a single time and it works for partner #2 and partner #20 with no new code. And because mappings are reusable, common retailer formats are often already mapped — so your next partner can be live almost immediately.

What HeddleGrid handles, so you don't

The unglamorous, error-prone plumbing of EDI — managed end to end.

Transport

AS2, SFTP & VAN — endpoints hosted, certificates generated and rotated for you.

Control numbers & dedupe

Interchange/group numbering and duplicate detection — never a dropped or double-sent document.

Functional acks (997)

Sent for everything inbound, reconciled for everything outbound — automatically.

Validation & compliance

Every document checked against the partner's rules before it leaves the building.

Exceptions

Anything that fails lands in one guided worklist with a plain-language fix.

Retries & replay

Automatic retries on delivery, and one-click replay of any document or event.

03 Own the loom

One stack, top to bottom. No black boxes.

Most "EDI" products are a thin skin over someone else's translator and someone else's network. HeddleGrid owns the whole loom — so onboarding, correctness, and pricing are ours to fix, not a vendor's to gatekeep.

04 Why apparel

Built by operators who live apparel supply chains.

Generic EDI treats your purchase order like any other row of data. HeddleGrid knows what a style code, a prepack, and a multi-DC routing actually mean — because we live it.

DPCI & pack-aware

Styles, colorways, prepacks and inner/outer cartons map to your catalog, not a generic line item.

ASN that passes

SSCC labels, hierarchical 856 loops and timing rules tuned to each retailer's compliance program.

Multi-DC routing

One PO, many destinations — split, routed and tracked the way big-box actually ships.

Into production

Orders don't stop at the inbox — they flow through to production and shipment visibility no pure-EDI vendor can follow.

05 Pricing

Priced to switch. Not to punish.

Every vendor's mix of retailers and volume is different, so we scope pricing to fit — no setup fees, no per-document metering. Tell us your trading partners and we'll put together a plan.
