In practice

NMBS EDI overview

NMBS EDI is the structured exchange of commercial documents between NMBS and businesses working in UK retail and wholesale supply. The agreed document set starts with orders and invoices, with the operational emphasis on coordinating commercial data across internal systems.

A practical NMBS integration should connect order and invoice data with ERP and accounting workflows. XEDI maps the agreed Agreed EDI format messages into ERP, warehouse, accounting or API workflows, while validation and alerts help teams deal with exceptions before they affect delivery or payment.

Every document validated before it moves

XEDI checks each NMBS order, despatch advice and invoice against the required format, so errors are caught before they reach your systems.
