CJ Lang-Specific Requirements

Orders in, invoices out.
The detail is in the rules.

CJ Lang's flow looks straightforward on paper. The work is in the supplier and location codes, the tolerance rules on every invoice and the format CJ Lang expects each message to follow. Get any of it wrong and you eat a deduction. Supply Lens is configured for those rules out of the box.

Direct connection

CJ Lang 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.

Message format handled

CJ Lang uses the long-established UK retail message format, as most large UK retailers still do. Supply Lens generates and reads it correctly so the format stays invisible from your ERP's point of view. The order just arrives.

EAN to item code mapping

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

Invoice tolerance rules

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

Distribution centre routing

Each CJ Lang PO names a destination DC by code. Supply Lens maps every active CJ Lang location to the correct routing in your warehouse system, so the order lands against the right depot in your ERP without manual intervention.

Cost list and pricing rules

Your agreed CJ Lang cost list is registered in Supply Lens. Promotional pricing, cost changes and tier breaks are all applied automatically when an invoice is generated, so the price CJ Lang sees on the invoice always matches what was agreed.

Document Flow

Every document.
Every direction.
Automatically.

Supply Lens handles the full CJ Lang 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 PO and your agreed CJ Lang cost list before transmission
  • Credit notes raised and transmitted when returns or adjustments occur
  • Tolerance, location and pricing rules applied per message automatically
  • All CJ Lang-specific document structures generated and read correctly without your team seeing the format

Configuration

Configured for CJ Lang.
Connected to your
system.

Supply Lens holds CJ Lang's 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

CJ Lang supplier onboarding

Your CJ Lang supplier code, GLN and trading partner profile registered with CJ Lang's gateway. Supply Lens manages the connection identifiers and certificates, so there is no setup needed your side.

2

EAN and article cross-reference

CJ Lang EANs and article 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

DC routing and entity mapping

Each CJ Lang DC code mapped to your correct warehouse, customer account or entity in your ERP, so orders route cleanly to the right despatch point on receipt.

4

Tolerance and pricing rules

Your agreed CJ Lang cost list registered for invoice validation. Tolerance rules applied per supplier agreement, so price discrepancies surface your side first.

CJ Lang Edge Cases

The situations that
catch suppliers out.

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

"CJ Lang send documents in a format our system cannot read. We've been doing it manually for months."

The format never reaches your system. Supply Lens turns CJ Lang's purchase order into a clean payload your ERP already understands and renders your outbound invoice in the structure CJ Lang requires on the way back out. Your team works in their normal interface, the format conversion happens in the Supply Lens layer.

"CJ Lang deducted against an invoice because the unit price was a few pence off the agreed cost list."

Invoice values are validated against the originating PO and your agreed CJ Lang 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 CJ Lang deduction weeks later.

"A new CJ Lang promotional line started arriving and our system rejected the order because the price didn't match."

Promotional pricing is held against your CJ Lang cost list and applied per line at invoice time. New promotional EANs map to existing items where possible. Any unmapped reference goes to an exception queue immediately rather than rejecting the order outright.

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

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