Sainsbury's-Specific Requirements

Sainsbury's runs its own
EDI infrastructure.

Unlike retailers that route through a shared VAN, Sainsbury's runs its own direct connection. Supply Lens connects straight to the Sainsbury's network, removing one intermediary, cutting transmission latency and simplifying the setup path for new suppliers.

Direct connection

Supply Lens connects straight to the Sainsbury's network rather than via a third-party VAN. That means faster transmission, fewer dependencies and a simpler onboarding path, with no VAN account required on your side.

Strict invoice tolerance rules

Sainsbury's applies tighter invoice matching than most UK grocers. Supply Lens validates invoices against your agreed Sainsbury's tolerance rules before every submission, flagging price and quantity issues your team can resolve before Sainsbury's finance sees them.

Location cross-reference

All Sainsbury's 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.

Product cross-reference

Your products are imported into Supply Lens once. The workflow then resolves Sainsbury's EANs to your internal item codes on every order, including pack-size variants and promotional lines, without any ongoing manual maintenance.

Every format handled

Sainsbury's uses different document formats for purchase orders and despatch advice, with no order acknowledgement step in the cycle. Supply Lens translates every format to clean records in your ERP, so your team never touches the underlying message structure.

Invoice Tolerance Rules

Sainsbury's invoice
matching is strict.
Supply Lens checks first.

Sainsbury's operates tighter invoice tolerances than most UK grocers. Supply Lens validates every invoice against your agreed Sainsbury's tolerance rules before it is transmitted, flagging issues your team can resolve before Sainsbury's finance sees them.

  • Price per unit validated against the agreed price list before the invoice is sent
  • Quantity on the invoice checked against the actual shipped quantity on the despatch advice
  • VAT treatment and tax codes validated per product line
  • Promotional pricing handled separately, never mixed with standard price lines
  • Discrepancies held in exception queue with full context for your team to review
  • Corrected invoices re-transmitted automatically once approved
Invoice validation

Supply Lens validates invoices against your agreed Sainsbury's tolerance rules before transmission. Price, quantity and invoice total are all checked against the originating PO. Any issue is held and flagged for your team to resolve before it reaches Sainsbury's finance team.

Sainsbury's Edge Cases

The situations that
catch suppliers out.

Sainsbury's invoice and delivery compliance requirements are among the strictest in UK grocery. Supply Lens handles the scenarios that typically generate deductions and payment holds.

"Our invoice was held because the unit price was a fraction of a penny different from the PO."

Sainsbury's applies strict price matching on invoices. Supply Lens validates the unit price on every invoice against the original purchase order line before transmission, flagging any discrepancy for review rather than sending it and risking a deduction later.

"We sent the despatch advice to the wrong DC and the delivery was refused at the gate."

Sainsbury's DC GLNs follow a distinct structure and each depot has a specific code that must appear on the despatch advice. Supply Lens resolves the correct depot reference from the purchase order's delivery location, so a wrong-depot despatch advice is not possible once routing is configured.

"We have promotional pricing running on two lines but standard pricing on the rest of the order."

Promotional and standard prices cannot share an invoice line in the Sainsbury's specification. Supply Lens automatically splits mixed orders into separate invoice lines, with promotional prices itemised correctly and standard lines invoiced at the agreed rate.

"We didn't realise the despatch advice had to be a different format from the purchase order Sainsbury's sends us."

Sainsbury's uses different formats for purchase orders and despatch advice. Supply Lens handles both over the same connection, so your team never manages the format difference: the correct one is applied automatically for each document.
