The procurement, titled "TABS Software Licensing + Support & Maintenance," falls under the IT services category and is considered vital for Network Rail's operations. The engagement with Aptitude Software Limited is set to begin on 23rd June 2025, for a three-year period, concluding on 30th June 2028. This strategic procurement aims to enhance Network Rail's Track Access Billing Programme, ensuring improved management and accuracy of billing functions across the UK's railway infrastructure. Located in London, with procurement governed by UK central government regulations, this process bypassed competition based on technical reasons and unique supplier rights, as per the New Procurement Act 2023. This procurement offers valuable opportunities for businesses involved in IT consultancy, software development and support, especially those with expertise in Microsoft Windows environments, .NET technologies, or specialised financial modelling. Although the direct award favoured Aptitude Software Limited due to their unique capabilities and long-term relationship with Network Rail, businesses equipped to handle software upgrades, technical support, and web application development may explore new opportunities for tenders with similar requirements in the future. Successful engagement in such contracts can significantly broaden a company's portfolio within the public sector, and provide stable long-term projects. ## Notice This requirement is for a three year renewal for the Microgen Aptitude Software Licence, Maintenance and Support Agreement with Aptitude Software Limited via a Single Tender Action (STA) commencing on 23/06/2025. The "Track access billing programme" has been established within Route Services IT to deliver a consolidated software application, database and infrastructure for the recording of Track Access, Compensation Payments (Planned and Unplanned) and the maintenance of reference data. The Billing programme is a strategic programme to improve the way in which the billing function for Network Rail (NR) is carried out and managed by the organisation. As a longstanding client of Aptitude since 2008, Network Rail has leveraged Aptitude Software Limited platform to support critical internal operations through a customised application built and maintained using the Aptitude Platform. Key Areas of Support: * Web Application Development Network Rail uses the Aptitude Platform's web application generator to develop and operate an internal application. Uniquely, they run their environment on Microsoft Windows, utilising IIS (Internet Information Services) and .NET technologies, rather than the more common Linux-based setup. * Calculation Capability The platform supports core business calculations - specifically, those used to model and determine the fees other companies must pay to access and use railway infrastructure. These financial models are essential to Network Rail's operations. * Ongoing Upgrades and Technical Support Aptitude has supported several platform upgrades over the years, with the most recent migration to version 24.4.1. We assisted in resolving issues during this process, particularly compatibility concerns with Windows Server 2022. * Testing and Migration Status Network Rail is in the final phase of testing their newly upgraded application. Most system tests have been completed successfully, with a few final validations currently underway. * Continued Engagement While direct development work has been minimal since 2019, Aptitude continues to provide proactive technical support, version upgrades, and assistance with troubleshooting to ensure continued platform stability. ### Procurement Information This award is compliant with the New Procurement Act 2023 under section 41 referencing I7 Sch. 5 para. 4 and para. 5 ; competition is absent for technical reasons .
