What Sainsbury’s actually requires

Sainsbury’s ASN matching is stricter than most retailers — line totals, pallet hierarchies, and SSCC codes all have to reconcile or the delivery is refused at the depot.

ORDERS

Inbound purchase order. EDIFACT format. Aduno parses it and pushes structured data into your order management system.

DESADV

ASN with full pallet hierarchy and SSCC labels. Sainsbury’s checks line totals, case quantities, and pallet structure against the original ORDERS — mismatches mean refused deliveries.

INVOIC

Invoice referencing both the PO and the ASN. Three-way match must reconcile. Aduno validates pre-send.

RECADV + CONTRL

Goods receipt confirmation and functional acknowledgements. Aduno generates and reconciles both automatically.

14 days, four milestones

Fixed scope, fixed price. We handle the EDI transport, the AI handles the mapping, and we monitor the first 50 transactions end-to-end.

Step 1
Day 1

Scoping call

We confirm your Sainsbury’s supplier number, the SKUs in scope, and the systems on your side (ERP, WMS, or spreadsheet — Aduno connects to all of them).

Step 2
Days 2–6

Connect & map

We set up the EDI transport (AS2 or VAN), register your GLN, and our AI builds the EDIFACT mappings for every required document type.

Step 3
Days 7–11

Test cycle

Test transactions through Sainsbury’s EDI test environment. Every ORDERS gets a matching DESADV and INVOIC; every pallet hierarchy reconciled.

Step 4
Days 12–14

Go live

First production PO flows end-to-end. We monitor the next 50 transactions and catch any ASN-mismatch risk before it costs you a refused delivery.

Frequently asked

Sainsbury’s told me to use SPS Commerce / Tradeshift. Can I use Aduno instead?

Yes. Sainsbury’s accepts EDI from any compliant provider — the named vendors are recommendations, not requirements. Aduno connects via standard AS2 or VAN, exactly the same way.

How does Aduno handle Sainsbury’s ASN matching rules?

This is one of the main reasons brands choose Aduno. Every DESADV is validated against the original ORDERS before it leaves your system — line totals, case quantities, pallet hierarchy, SSCC labels. If anything is off, we surface it to your team before Sainsbury’s sees it. ASN-related chargebacks are the #1 cost most new suppliers don’t budget for.

What about Argos and Habitat (also Sainsbury’s group)?

Argos and Habitat use related but distinct EDI requirements. Aduno supports both — worth a scoping call to confirm exactly which Sainsbury’s group entities you’ll be supplying.

What if my finance system is Sage, Xero, or NetSuite?

Aduno’s AI mapping connects to anything that exposes data — REST APIs, CSV exports, even PDFs. You don’t need an ERP that “speaks EDI”; we translate.

What does the 14-day connection guarantee actually mean?

If we don’t have you sending validated test transactions to Sainsbury’s EDI test environment within 14 days of kickoff, your fee is refunded. The actual go-live date depends on Sainsbury’s onboarding queue — we don’t control that — but we guarantee we’ll be ready when they are.
