Waitrose-Specific Requirements

Waitrose operates within
the John Lewis Partnership.

Waitrose trading runs through the John Lewis Partnership's central infrastructure. Documents are exchanged over the same managed network the Partnership uses for its wider supplier base. Supply Lens holds that connection and handles the Waitrose-specific document requirements, supplier codes and location GLN mapping.

managed network connection

Waitrose documents are transmitted over the John Lewis Partnership's managed network. Supply Lens already holds that connection, so you do not need an account of your own. Messages route through the Partnership infrastructure from day one.

Location cross-reference

All JLP distribution centre codes and GLNs are pre-loaded in Supply Lens. Location cross-referencing is triggered automatically during the order workflow with no depot routing setup required from you.

JLP supplier code structure

Waitrose assigns each supplier a JLP-specific vendor code used to identify your business across all messages. Supply Lens configures your JLP vendor code at the integration level so it is always applied accurately.

Product cross-reference

Your products are imported into Supply Lens once. The workflow then resolves Waitrose EANs and article numbers to your internal item codes on every order. Core range, seasonal lines, and exclusive products are all handled automatically.

Invoice and payment terms

Waitrose invoice matching is based on agreed cost prices and confirmed quantities. Discrepancies between the invoice and the originating purchase order are flagged before submission. Supply Lens validates price and quantity against the PO before every invoice is transmitted via the managed network.

Document Flow

Every document.
Every direction.
Automatically.

Supply Lens automates the complete Waitrose document process, removing the need for manual document creation, rekeying or intervention. This helps suppliers process every document accurately, efficiently and within the Partnership’s required compliance timescales.

  • Purchase order: Waitrose purchase orders received and validated over their managed network
  • Despatch advice: pallet label references transmitted as goods leave your warehouse
  • Invoice: Invoice submitted with correct JLP supplier codes and tax treatment
  • No order response or control acknowledgement in this flow
  • All messages routed via the John Lewis Partnership managed network

Waitrose Edge Cases

The situations that
catch suppliers out.

Waitrose holds its suppliers to the same quality standards it applies to its products. Compliance is taken seriously, and routing errors, late despatch advices and invoice discrepancies are followed up promptly.

"We weren't set up on the managed network, and Waitrose told us we needed to sort our own connection."

Supply Lens already holds the connection to the managed network the John Lewis Partnership uses. New suppliers do not need to establish an account of their own, and Waitrose trading is live through the Supply Lens connection from day one of onboarding.

"We sent the despatch advice with the wrong depot code, so the Bracknell depot rejected the delivery."

Partnership depot GLNs are held in Supply Lens and resolved automatically from the delivery location on the purchase order. Once the depot to GLN mapping is configured, the mapping is applied at the integration layer rather than by your team manually, which is what stops the wrong GLN reaching a despatch advice.

"We supply both Waitrose and John Lewis. Do they need separate setups?"

Waitrose and John Lewis trade under the same Partnership infrastructure over the same managed network. Supply Lens handles both as a single relationship, with separate supplier codes and routing rules for each trading name. One connection, correctly separated at the document level.

"Our EAN was listed under a different article number in the Waitrose product file than in our own system."

Waitrose article number and EAN mismatches are resolved through the Supply Lens cross-reference table, which maps the Waitrose product reference to your internal item code. When Waitrose updates their product file, the mapping is updated in Supply Lens without touching your ERP.

Getting Set Up

What you need
to go live with Waitrose.

Waitrose onboarding involves their Partnership supplier trading team, your routing details and your product and depot data. Supply Lens manages the network connection and configuration. You provide the inputs.

  • Waitrose JLP supplier / vendor number
  • GS1 GLN for your business, used as your sender identification
  • ERP or IMS credentials (Unleashed, CIN7, Enterpryze, or other)
  • Agreed cost price list for invoice validation
  • Sample Waitrose POs (real examples where available)
