Dunnes-Specific Requirements

Orders in, four documents out.
The detail is in the rules.

Dunnes looks straightforward on paper. The work is in the two market entities, the supplier and depot codes, the tolerance rules on every invoice and the despatch advice timing. Get any of it wrong and you eat a deduction. Supply Lens is configured for those rules out of the box.

Direct connection

Dunnes receives supplier documents through a direct connection. Supply Lens manages the certificates, the partner profile and the gateway on your behalf, so you have no gateway of your own to build, run or maintain.

Two markets, one connection

Dunnes trades in the Republic of Ireland and Northern Ireland, and the two are not interchangeable. Supply Lens routes each order to the right entity in your ERP with the correct currency and tax treatment, so euro and sterling business stays separate in your books without a second connection to maintain.

EAN to item code mapping

Dunnes identifies products by GS1 EAN and an internal product reference. Supply Lens maintains a cross-reference table mapping both to your own item codes, so the order lands correctly in your ERP regardless of which identifier Dunnes sends.

Invoice tolerance rules

Dunnes applies strict invoice matching on price and quantity. Supply Lens validates the invoice against the originating purchase order and your agreed cost list before transmission, flagging any discrepancy for review rather than sending it and risking a deduction later.

Depot routing

Each Dunnes purchase order names a destination depot by code. Supply Lens maps every active Dunnes location across both markets to the correct routing in your warehouse system, so the order lands against the right depot in your ERP without manual intervention.

Credit notes accepted

Most retailers will not take a credit note over the connection, so suppliers end up raising them by hand. Dunnes does accept them. Supply Lens matches each credit against the original invoice and sends it through the same flow, so short deliveries, returns and price corrections settle without a manual process running alongside.

Document Flow

Every document.
Every direction.
Automatically.

Supply Lens handles the full Dunnes document set inbound and outbound, so documents are produced and transmitted automatically, without manual rekeying.

  • Purchase orders received and validated against your supplier profile
  • Invoices pre-validated against the purchase order and your agreed Dunnes cost list before transmission
  • Despatch advices sent as goods leave, with pallet detail and depot booking reference attached
  • Credit notes raised, matched to the original invoice and transmitted through the same connection
  • Tolerance, depot and pricing rules applied per message automatically
  • All Dunnes-specific document structures generated and read correctly, with ROI and NI kept separate throughout

Configuration

Configured for Dunnes.
Connected to your
system.

Supply Lens holds Dunnes' rules and the connection itself so you don't have to. Your team provides credentials, product mappings and the agreed cost list. Everything else lives in the Supply Lens layer.

1

Dunnes supplier onboarding

Your Dunnes supplier codes and GLNs for each market registered with Dunnes' gateway. Supply Lens manages the connection identifiers and certificates, so there is no setup needed your side.

2

EAN and product cross-reference

Dunnes EANs and product references mapped to your item codes. Pack-size variants, promotional lines and multi-pack SKUs are handled automatically once their cross-reference is established.

3

Depot routing and entity mapping

Each Dunnes depot code mapped to your correct warehouse, customer account or entity in your ERP, with ROI and NI orders routed to the right entity and currency on receipt.

4

Tolerance, pricing and credits

Your agreed Dunnes cost list registered for invoice validation per market. Tolerance rules applied per supplier agreement, and credit notes matched to the invoice they correct, so discrepancies surface your side first.

Dunnes Edge Cases

The situations that
catch suppliers out.

Supply Lens handles the scenarios that typically cause invoice rejections, deductions or document mismatches in the Dunnes flow.

"Our ROI and NI Dunnes business keeps landing in the same place and the VAT is wrong."

Each market is resolved before the order reaches your ERP. Supply Lens reads the entity on the incoming purchase order and routes it to the matching customer account, currency and tax treatment your side, so euro and sterling business never has to be untangled after the fact.

"Dunnes deducted against an invoice because the unit price was a few cent off the agreed cost list."

Invoice values are validated against the originating purchase order and your agreed Dunnes cost list before submission. Discrepancies are flagged before the invoice is sent, giving your team a chance to correct or query rather than receive a Dunnes deduction weeks later.

"We short-delivered two lines and now the credit note is being raised by hand outside the system."

Dunnes accepts credit notes over the connection, so there is no need for a manual process alongside. Supply Lens matches the credit to the invoice it corrects, applies the same validation the invoice went through and transmits it through the same flow. Short deliveries, returns and price corrections all settle the same way.

"A new Dunnes EAN started arriving and our system rejected the order because the product wasn't mapped."

Unrecognised EANs go to an exception queue immediately. The order is held, your team is notified with the full Dunnes context, the mapping is added and the order is re-triggered. No silent drop, no late invoice, no missed delivery window.
