## Summary

The procurement process involving Post Office Limited, titled "Horizon Replacement Services - Replacement Service Provider and COTS-EPOS-SaaS," has reached its completion stage. The competitive flexible procedure comprises two lots: Lot 1 being awarded to Accenture (UK) Limited for the Replacement Service Provider role, and Lot 2 awarded to OneView Commerce, Inc. for the COTS-EPOS-SaaS solution. The project, located in the United Kingdom, aims to transition and transform the existing Horizon system into cloud-based technologies.

An extended standstill period for Lot 2 lasts until 26 June 2026, with the contract officially commencing on 27 June 2026, lasting until 2036, with possible extensions to 2038.

This procurement creates significant business growth opportunities, especially for companies equipped to deliver modern IT services and software solutions.
