Purchase to pay

Drive down procurement costs with GS1 and PEPPOL standards

Purchase to pay

Sometimes known as e-invoicing, this part of the NHS eProcurement Strategy is all about automating how you order, receive and pay for goods and services.

Unlike the rest of the NHS eProcurement Strategy, which is centred around GS1 standards, purchase to pay requires Trusts to use PEPPOL messaging standards as well.

PEPPOL messaging standards enable the electronic transfer of information between Trust and supplier without manual intervention – in other words machine-to-machine transaction processing.

When used with GS1 standards for uniquely identifying products and locations, PEPPOL enables automated matching of orders, invoices and delivery notes, reducing costs and speeding up subsequent payments.

The benefits

  • Increased control of purchasing
  • Improved ordering and invoicing accuracy
  • Fewer invoice queries
  • Improved cash flow
  • Increased traceability of products
  • Increased patient safety

What an efficient purchase to pay system looks like

  1. A PEPPOL access point has been selected and there’s a commercial agreement between the access point provider and the Trust
  2. The Trust has instructed its suppliers to select a PEPPOL access point
  3. The Trust has required its suppliers to use their access points to trade electronically with the Trusts’ access point
  4. 95% of purchase order transactions are generated via auto-replenishment and sent to the access point without manual intervention
  5. 95% of invoices transactions are received from the access point and are processed on the Trust’s local systems without manual intervention
  6. An appropriate and sustainable purchase to pay structure is in place
