## Summary

Southern Water Services Limited is currently in the planning stage of procuring a Source to Pay Software Solution and Software Implementation Partner. This procurement opportunity falls under the industry category of software programming and consultancy services, specifically in the region of South East England (UKJ). The procurement process is set to commence on 1st April 2025 with the future notice date. The procurement method is an open tender, and the project's main objective is to implement an intuitive, cloud-based solution that enhances user experience in purchasing goods and services, covering both Source to Contract and Purchase to Pay processes.

This tender presents a significant growth opportunity for businesses specialising in software integration, implementation, and supply services. Ideal candidates are those who can offer proven, secure mobile and computer-based solutions, with capabilities for supplier portal access and integration with common financial or HR platforms. Additionally, certified Solution Implementation Partners with experience in managing professional services and goods contracts are well-suited to compete. This is a strategic chance to partner with Southern Water and support them in streamlining their procurement processes, making it an attractive prospect for qualified software solution providers and their certified partners.

## Notice

Southern Water ("SW") seek a Solution Provider to licence a cloud-based, Source to Pay software solution ("Solution") that will give SW users a more intuitive experience in purchasing goods and services. The Source to Pay process ("S2P") comprises of Source to Contract ("S2C") and Purchase to Pay ("P2P") processes. The Solution will provide end-to-end functionality. In registering interest, the Solution Provider is asked to identify up to three (3) Solution Implementation Partners ("SIP"), indicating a preferred SIP. All SIPs must already be certified by the Solution Provider, to be able to support in the configuration and implementation of the Solution.

### Lot Information

Lot 1

P2P: The Solution will manage SW's end-to-end procurement processes from capturing a Requirement, through Purchase Requisition, Approval, Purchase Order Creation, Supplier PO Receipting, SW Service/Product Receipting, Supplier Invoicing to "OK to pay" from a 3-way match. Critical to improved user experience will be that the Solution will enable users to: - execute required actions "on the move" via secure mobile technologies as well as computer based, - leverage punch-outs with external approved and secure supplier sites - access and order from approved supplier catalogues The Solution must have a proven method of: - managing professional services - goods and works contracts that may leverage Framework Agreements and timesheets. These areas represent a key portion of the SW spend profile. The nature of managing this spend in this Solution is still being defined but will be clarified later in the Procurement Process. S2C: For spend that is not readily available when requisitioned, the Solution would also have integrated Sourcing, Contracting and Supplier / Contract Performance Management functionality, that is triggered by workflow management to a central Procurement function. All S2P activities must workflow automatically and allow for online collaboration between SW colleagues and Suppliers, who will be able to access the Solution via a secure external Supplier Portal. The number of integrations to legacy SW systems is still being defined, but we would expect the Solution to be able to readily integrate to common Finance or HR platforms as a minimum and have SSO capability. It must also have the capability to be integrated with Asset Management, Inventory and Stores solutions, as a possible further future activity. (Although this is not in the initial implementation scope, it is essential there is evidential functional capability to do so.) The Solution Provider will identify three (3) SIPs, and a preferred SIP. All SIPs must be certified by the Solution Provider.
