## Summary

HM Revenue & Customs (HMRC) is currently in the planning stage of a procurement process aimed at enhancing their existing communications solutions, titled "Communications Platform as a Service (CPaaS) and Customer Communications Solution". This initiative falls under the software package and information systems category and is situated in the United Kingdom. The procurement process is in the market engagement phase with a scheduled milestone due date on 4th September 2026. The procurement aims to explore market capabilities and potential innovations in communication technologies, with a contract period from 1st October 2028 to 1st October 2033. This is an opportunity for interested parties to submit Expressions of Interest to HMRC by engaging with the market engagement notice found on the appropriate channels.

This market engagement presents significant growth opportunities for businesses specialising in communication platforms, customer engagement technology, and related software services. Ideal candidates are businesses with capabilities in multi-channel communications, service transition, and compliance solutions that are scalable for large governmental operations. Innovative companies engaged in AI, automation, and customer journey orchestration may find themselves well-suited to contribute valuable insights during HMRC’s exploration of future technological roadmaps. The market engagement encourages participation from a diverse range of suppliers who can demonstrate experience with public and private sector clients, positioning this as a fertile ground for expansion into government contracts.
