Source to Pay (S2P) Transformation
Streamline your procurement operations from sourcing to supplier payment.
S2P: how we can help
At Accelerate Procurement, we help organisations simplify, digitise, and optimise their entire Source to Pay (S2P) process. Our strategies align people, processes, and systems to drive efficiency, reduce risk, and unlock long-term value.
Whether you’re looking to select and implement new technology, improve supplier engagement, or reduce manual tasks and maverick spend, our experts will support you through every step of your transformation.
What is Source to Pay (S2P)?
S2P covers the full procurement lifecycle, from strategic sourcing through to payment and supplier performance management. Unlike Procure to Pay (P2P), which focuses on operational buying and payment processes, S2P includes upstream activities such as sourcing, contract management, and supplier relationship management, giving you a comprehensive, end-to-end view of your procurement function.
Our Source to Pay transformation service
At Accelerate Procurement, we tailor our S2P services to your organisation’s needs, systems, and goals. Whether you’re at the start of your digital procurement journey or upgrading a legacy platform, we deliver strategic and practical support to ensure your S2P solution drives real results.
S2P strategy & roadmap development
We work closely with your team to assess your current processes, systems, and data. From there, we develop a clear roadmap to guide your transformation, defining objectives, success metrics, and implementation stages that are realistic and achievable.
System selection & implementation
We help you navigate the complex S2P technology market to choose the platform that best suits your organisation. Our independent guidance covers everything from business requirements and vendor shortlisting to commercial negotiation and implementation planning.
We’ve worked with a range of leading platforms, including SAP Ariba, Coupa, Jaggaer, Oracle, and bespoke solutions, and can support implementation from both a strategic and hands-on perspective.
Process design & optimisation
We map and redesign procurement processes to reduce inefficiencies, improve user experience, and ensure compliance. Our approach is always collaborative, balancing best practice with the realities of your organisation’s culture and operating model.
Change management & capability building
We don’t just deliver a system and walk away. We support change management, training, stakeholder engagement, and knowledge transfer to ensure your team is empowered and ready to adopt new ways of working.
Benefits realisation & continuous improvement
Our job isn’t done once the system goes live. We work with you to measure impact, track ROI, and identify further areas for improvement, embedding S2P as a long-term driver of procurement value.
Our unique approach to Source To Pay
We don’t just implement systems, we future proof your procurement function through:
-Procurement-led approach to technology and process
-Deep expertise in both upstream and downstream procurement
-Proven delivery across public and private sector
-Practical, hands-on support, not just theory
-Focused on capability-building, not dependency
S2P implementations are complex. Our consultants have managed multiple S2P implementations and understand how to navigate the challenges. They are familiar with the strengths and weaknesses of the tools and aware of the common pitfalls.
Many organisations understand the benefits of S2P and are keen to implement it, but are concerned that they don’t have the time or expertise in house. This is where a procurement consultancy like Accelerate can really help: our consultants are experienced in implementing S2P and can support at any point in the process, from setting up the project and conducting periodic healthchecks all the way through to change management and business readiness.
