Re-Imagining S2P in the Era of Autonomous Procurement

S2P then and now: Towards autonomous spend management

No one can deny the immense evolution of source-to-pay (S2P) technology in recent years, not to mention the manner in which it has transformed operations within businesses of all shapes and sizes. 

Over the last 10 years, it has evolved from the use of procure-to-pay (P2P) and legacy systems, which created data silos, into a more sophisticated, connected method, driving business value for organisations of all sizes. While the original technology was primarily focused on cost reduction and automation, modern S2P now offers a multifaceted value which has a direct impact on profit.

Procurement was previously hampered by systems operating independently and in isolation – leading to a lack of visibility and preventing strategic decision-making.

But, as S2P has evolved, it has merged separate systems into integrated platforms – bringing sourcing, procurement, invoicing and payment processes together into one seamless workflow. The result? Companies are armed with the tools required to efficiently manage their spend and supplier relations. 

Today, we've reached the era of total spend management, where unified S2P platforms handle all spending categories – direct, MRO and indirect – while enabling cross-functional collaboration across the enterprise. 

In future, organisations will manage their spending seamlessly and intelligently through AI-powered, automated processes that require minimal human intervention. Leveraging collective data and insights from a global business community stands to optimise efficiency, value and sustainability in every transaction. This approach empowers businesses to drive growth and resilience while fostering responsible and ethical operations.

Organisations are being handed the data and AI-powered insights needed to manage spend in ways that protect margins, drive profitable growth and design supply chains that respond smarter and faster to disruption. These intelligent systems are now moving toward autonomous spend management, where AI and machine learning can identify opportunities, recommend optimal actions and even execute routine procurement decisions with minimal human intervention.

Beyond cost savings: Multiple drivers of profitable growth

S2P platforms empower businesses to make data-driven decisions that enhance efficiency, mitigate risks and drive profitability. For example, organisations leveraging S2P have reported faster time-to-market for new products due to improved supplier collaboration and optimised payment timing that strengthens working capital management.

With S2P, businesses now have a tool which can work at the heart of driving profitable growth, rather than a more one-dimensional approach, which worked almost exclusively on securing pricing discounts.

This means that a solid S2P bedrock can be relevant for businesses of any size and industry – from enterprises to small and midsize businesses on their growth journey.

Spend data analysis

Using an S2P platform, businesses consistently capture and analyse comprehensive spend data. Centralising these insights within an S2P process gives teams across the business the opportunity to gain unprecedented visibility and insight into spending patterns, supplier performance and operational efficiency.

Direct and indirect

S2P continues to evolve and address complex challenges within a procurement function, such as its ability to manage both direct and indirect spend. Direct spend—typically associated with raw materials and production inputs—is now seamlessly integrated with broader procurement workflows, ensuring compliance with negotiated contracts and optimising costs in high-value categories. On the other hand, indirect spend—covering office supplies, marketing services and other operational expenses—benefits from automation tools that simplify tail spend management and reduce inefficiencies.

Emerging technologies

Technology advances also continue to reshape S2P. The emergence of tools like generative and agentic AI is driving efficiency and strategic value across procurement. Through the automation of repetitive tasks, such as supplier onboarding, AI is freeing up procurement teams to instead be strategic drivers at the heart of their companies. By utilising AI alongside tools such as predictive analytics, procurement is fast becoming a far more strategic function, able to make well-informed decisions.

Navigating transformation

Many ERP providers have an S2P solution (or S2P components) and business leaders have their reasons for thinking this is sufficient, whether due to cost or a long and trusted relationship with the provider. But, with every passing day, it is clear that procurement is moving towards a future which is an autonomous, data-driven and strategic environment. Business leaders are leveraging advanced technologies like generative AI to enable dynamic pricing insights, real-time sourcing recommendations and automated contract negotiations. The need for an approach designed with modern procurement in mind will be instrumental in helping organisations navigate this transformation successfully as procurement continues its journey from tactical function to strategic business partner.

A shared vision of transformation

Before jumping head-first into S2P adoption, businesses should establish a roadmap to work out exactly what they want to achieve as a result of the transformation.

The most successful companies are those which start with people alignment. Cross-functional collaboration isn't merely beneficial, but fundamental to the success of any S2P initiative aimed at driving profitable growth across the business.

S2P is designed to unify, so it’s vital that leaders across the business are working towards a common goal and avoid siloed objectives. This has the potential to emerge as finance focuses on cost reduction while procurement prioritises supplier relationships, creating competing rather than complementary goals. 

Especially with figures reported by Coupa’s The Strategic CFO Survey, which found  73% of CFOs and finance leaders are never aligned with their CIO on strategic priorities.

Without a shared vision from the outset, organisations can encounter issues like stalled implementation as departments debate their differing priorities, resulting in extended timelines and diminished ROI. The ultimate consequence is partial value realisation; without unified adoption, S2P won't be as effective as it's designed to be.

Karan R. Bhatia, Global Head of Source2Value Solutions and Tactical Sourcing Services at Sanofi CHC Global Business Services said: “Every time we said, ‘can we substantially reduce the number of clicks, say from 10 to two clicks’, we weren’t just challenging the process from a business perspective, but also from an IT perspective of what’s possible in a new-age solution vs. a legacy solution. The collaboration across teams, especially digital, was immense.”

Legacy P2P systems cannot inform a strong roadmap.Instead, they create data gaps, process inconsistencies and limited visibility.

Consider counterparts' shoes

When it comes to making a business case, it’s necessary to understand what success looks like for the organisation. If leaders are familiar with the mandates and challenges their counterparts face, they can align S2P initiatives to deliver value that resonates with each stakeholder group.

Finance, for example, may be seeking enhanced forecast accuracy and financial predictability alongside improved working capital management and cash flow visibility; procurement’s aim might be to transition from tactical purchasing to strategic value creation while improving supplier performance management capabilities. 

The 2024 ProcureCon CPO-CIO Report, based on a survey 100 procurement, supply chain and risk management leaders from across the US and Canada, uncovered that 41% of companies say the CIO and CPO are equal partners in technology procurement, while 35% report that the CIO takes the lead and the CPO assists.

Once the diverse business objectives are clear, a unified S2P vision can help to address pain points, moving the conversation from departmental priorities to enterprise-wide value creation. The most successful S2P initiatives are those where cross-functional teams collaboratively define success metrics that matter to the entire business – not just individual departments. This shared ownership creates momentum that carries transformation initiatives forward, even when challenges arise.

Starting and maintaining pace with S2P

S2P – like any new piece of technology – brings with it new ways of working, so having a thoughtful implementation programme is vital. Replacing traditional, embedded patterns of work requires careful consideration of timelines, integration complexity and change management, ensuring the organisation realises benefits both quickly and sustainably.

Understanding real implementation timelines

Implementation timelines for S2P solutions vary significantly and often extend beyond initial projections. For enterprise-scale deployments, traditional implementations typically require 12-18 months, while mid-market organisations usually complete implementation within six to nine months. However, it is important to distinguish between the technical implementation of the solution and the timeline for realising meaningful value. While the platform itself can often be deployed more quickly, true value creation depends on factors such as user adoption, process optimisation and the development of strategies that enable teams to fully leverage the platform's capabilities. Organisations that overlook the distinction between implementation and value realisation may face extended periods of resource commitment before achieving measurable returns.

A modernised implementation approach focused on rapid time-to-value can reduce these timelines, allowing organisations to begin capturing benefits within weeks rather than months or years. This accelerated timeline translates directly to improved financial outcomes and faster achievement of transformation objectives.

Integrating or migrating a system presents a range of variables in implementation success and warrants careful evaluation. Full-scale integration with all existing systems often creates exponential complexity with minimal corresponding value. A more strategic approach prioritises integrating only what's essential for spend visibility and control, significantly reducing implementation time and cost.

Chris Duchene, former SVP Chief Procurement Officer at Summit Materials, said: “What am I actually going to get incrementally for the [ERP implementation] versus what am I going to get incrementally if I roll out a source-to-pay solution? The delta between the benefits was huge: 80%. That was the value coming out of the source-to-pay solution.”

Expansion through acquisition presents a distinct set of challenges. Leaders often find they are investing not only in comprehensive integration, but also migration when restructuring takes place. More flexible mindsets here will allow a business to put a stop to repeated integration efforts and associated costs. Firms should also evaluate the resources needed to continue onboarding onto legacy systems, which carries the potential for significant wasted investment that could instead be redirected towards more future-focused initiatives.

To realise the full potential of an S2P platform, organisation-wide adoption is essential. Despite its inherent benefits, limited usage by internal teams and suppliers will inevitably restrict value creation. A strategic change management approach targeting both stakeholder groups is critical for maximising return on investment

For internal users, higher adoption translates directly to increased spend under management—typically the most significant driver of S2P value. It represents millions in potential savings for mid-sized enterprises and tens of millions for larger organisations.

Supplier adoption is equally critical, but can sometimes be neglected during implementation planning. Prioritisation of supplier engagement enables true strategic collaboration beyond basic transaction processing. Swiss Re, which took advantage of the S2P platform offered by spend management giant Coupa, saw user adoption increase from 50% to more than 90%, reducing IT costs in half.

A shared definition of success

With the S2P platform up and running, attention will inevitably turn to its impact. Organisations measure “success” in different ways, but, once clearly defined, it’s crucial to build and maintain momentum. Establishing clear, meaningful metrics that resonate with stakeholders and drive continued progress is paramount. 

Focusing on outcomes, not activities

Organisations seeing the greatest success from S2P transformation often have clear, outcome-based metrics in place, as opposed to activity measures. Such metrics keep teams focused on business impact instead of becoming entangled in process details or technical capabilities. 

While implementation of a new S2P platform involves tracking projects, true transformation success is inevitably measured by its impact on business performance. When stakeholders can see how S2P initiatives directly contribute to organisational objectives, engagement and adoption naturally accelerate.

The transformation undertaken affects functions across the business in different ways and understanding this is essential to defining success metrics. A comprehensive measurement framework addresses what matters most to each stakeholder group while staying in touch with overarching business objectives.

Margin improvement stands as one of the more compelling metrics, as it connects directly to profitability. Unsurprisingly, artificial intelligence is increasingly coming into play here and those harnessing the AI capabilities found in some S2P platforms are seeing impressive growth in their margins. 

Shaun Carroll, Group Director of MSS and Chief Procurement Officer at Mitie, said: "The margin multiplier makes a massive difference. Every single pound we take out hits our bottom line. We've taken cost out across the procurement team, the accounts payable team and the supplier base."

The Hackett Group has found that firms investing in AI are expanding margins and driving durable growth, with 47% running at a lower cost, half spending less time on transactional activity and 44% more likely to be considered a valued business partner. 

Look no further than research from The Hackett Group, which every year engages nearly 8,800 global companies across various industries in a bid to define ‘Digital World Class’. Those deemed to be Digital World Class are described as being prepared to harness the capabilities of AI, including Gen AI, therefore giving them a head-start on their competitors. 

However, perhaps the most transformative element of S2P tech adoption is the ability to make faster, better-informed spend decisions by managing both direct and indirect spend through a unified platform. 

According to Forrester's Total Economic Impact study, organisations using Coupa's S2P platform have achieved an ROI of 276% with a payback period of less than 10 months. This is driven by efficiencies in sourcing, procurement, invoicing and spend management, as well as the provision of models eliminating the need for costly on-premises infrastructure and ongoing maintenance costs. Updates are handled automatically by the provider, further reducing IT overheads.

Building a measurement framework

As plans to undertake an S2P transformation unfold, there is a need for a balanced framework which addresses both immediate implementation success and long-term business impact. 

Decision makers should review and refine these metrics on a regular basis to assess whether the platform needs to evolve, examining:

• What is working and should stay the same;
• What measurements need to change going forward (AI can have a significant impact on how productivity is measured and even help businesses determine other things to measure).

The most successful organisations treat measurement not as a results exercise but as a continuous improvement mechanism that drives ongoing transformation.

Antti Koski, Head of Finance Development at Finnair, said: "With the redesigned processes [and platform], I feel we've been able to bring the business closer to procurement. We're actually able to serve the company better together, make the right decisions and understand how we spend money – and continuously improve."

Securing the future of business

Procurement is viewed as the team which saves money. Every purchase and each investment is under intense scrutiny to justify its place on the balance sheet. 

But this can be an advantage to procurement. As more and more CFOs look to make the tech stack lean, the team is well positioned to provide advice on how to make this a possibility. 

According to Morgan Stanley’s 2Q24 Domain Survey, purchasing up-to-date procurement (61%) and supply chain (55%) systems is second only to ERP on CFO agendas.

So, business need to ask:

• Is this the right partner?
• Is this provider the one to help my organisation grow and develop over the next two to five years?
• Will the S2P platform still be fit for purpose as my procurement function evolves? 
• Will the solution address future pain points?
• Will it offer new capabilities that ensure continuous improvement?’. 

Addressing tomorrow's challenges today

The most effective S2P strategies incorporate solutions businesses can "grow into" rather than quickly outgrow. This forward compatibility becomes particularly critical as organisations expand into new markets, introduce new product lines or pursue acquisition strategies. Evaluating whether the S2P approach can adapt to accommodate these scenarios represents an essential element of strategic planning.

This is harder than ever before to predict given the rapid evolution of AI and emergence of autonomous capabilities. Moreover, procurement and its activities are firmly under the microscope, seen as the team responsible for driving cost savings and sustainable efforts, in addition to taking responsibility for suppliers.

Procurement practitioners must map out a course of action, incorporating short-, medium- and long-term goals. 

Further questions must be asked here:

• Can the S2P platform scale in the event of an acquisition?
• Does the S2P solution offer the tools necessary to handle invoice payments and eliminate fraud?
• Is the S2P partner investing in the very latest technology to help the business stand out from competitors?

A useful starting point here is to examine the performance of potential S2P partners and how their efforts are powering procurement functions elsewhere. 

Coupa’s own track record speaks for itself:

• More than 350 new features developed every year (free of charge for existing users)
• US$200m committed to R&D every year
• Supplier sourcing and vetting cycles reduced by up to 75%
• More than US$1m in non-compliant spend detected for customers within the first year of turning on AI-powered fraud detection

S2P platforms should serve as enablers of a strategic vision rather than constraining it. The right solution will not only help measure current success through quantifiable metrics, whether in category management or fraud detection, but also provide the adaptable capabilities needed to thrive in tomorrow's global trade landscape. Unlike traditional ERP systems with rigid application structures, modern AI agent-driven platforms offer both the measurement framework for today's objectives and the flexibility to evolve with emerging business challenges.

The nature of today's business landscape means relying solely on traditional ERP systems for procurement is like navigating using historical charts rather than real-time navigation. 

AI-powered source-to-pay platforms deliver something fundamentally different: comprehensive visibility, continuous optimisation and intelligent guidance across the entire spending ecosystem. 

This isn't just automation; it's transformative business intelligence at scale. For leaders evaluating their technology roadmap, consider how the vendor's AI solution handles multi-ERP environments, what data it learns from and whether it has domain-specific procurement expertise. Remember that effective AI requires relevant, timely and ethically sourced data — something traditional ERPs weren't designed to deliver. By implementing purpose-built, AI-driven spend management, businesses not only keep pace with technology — but are positioned to make strategic decisions with unprecedented speed and confidence.

Within the modern business environment, relying solely on traditional ERP systems or apps is like navigating a ship using only historical weather charts — useful, but limited and reactive. 

In contrast, AI agent-driven platforms are akin to commanding a fleet of autonomous satellites delivering real-time storm prediction, wave analysis and continuous route optimisation across every ocean simultaneously. This isn't just automation; it's intelligent, adaptive business direction at scale.

For leaders considering S2P components within their ERP, the path to future-proofing lies in understanding how AI can transform spend management from a static process into a dynamic, insight-driven function. 

The right AI doesn't just automate — it learns and adapts, breaking down silos across multiple ERP instances to deliver holistic, actionable intelligence. But not all AI is created equal. 

Leaders should ask:

• How does the vendor's AI work across different or siloed ERP systems?
• What data does the AI learn from and does it bring true domain expertise in S2P or is it simply automating yesterday's processes?
• Is the data relevant, timely and ethically sourced—and does the platform protect sensitive information?

As highlighted by Coupa: "To gain a competitive edge with AI, you have to have the right data—relevant, timely and meaningful, yet also protected and safely, ethically sourced." 

Traditional ERPs were not built for this level of agility or intelligence. As businesses evaluate their options, look for autonomous spend management solutions that not only integrate seamlessly with the existing ERPs, but also leverage AI to deliver continuous improvement, actionable insights and a true competitive advantage.

S2P as a Catalyst for Profitable Growth

As businesses consider their S2P strategies within broader digital transformation roadmaps, the fundamental question becomes: how does the business want to enable growth, durably and profitably?

In today's volatile business environment, organisations require agility, visibility and control to navigate disruption successfully.

The modern S2P platform extends well beyond traditional cost savings tools, delivering multifaceted value through enhanced visibility, improved supplier relationships, optimised working capital and accelerated decision-making. This evolution has made comprehensive S2P relevant to organisations of all sizes, whether implementing for the first time or upgrading from component-based approaches.

Its ability to work cross-functionally is the cornerstone of its success. When business leaders collaborate to define shared objectives, the resulting transformation addresses enterprise-wide priorities rather than departmental needs. This alignment becomes particularly crucial as organisations navigate increasingly complex business environments requiring coordinated responses—a capability that purpose-built S2P platforms deliver more effectively than bolted-on ERP modules.

Martin Fogg, VP, Corporate Procurement, Processes & Digitalisation at Novo Nordisk, said: “It’s really exciting that procurement and our digital transformation is now supporting the growth of the company and also our ability to deliver on our promises to customers.”

Without these capabilities, organisations struggle to maintain competitiveness as more agile competitors capitalise on market opportunities and respond more effectively to disruption. Companies using fragmented procurement solutions or relying on ERP-adjacent tools find themselves at a particular disadvantage when market conditions rapidly change. The most successful businesses view S2P not as a cost centre but as a strategic enabler that directly contributes to profitable growth.

But what if a business decides to do nothing — to carry on as is? This path leads to an array of missed efficiency opportunities and increased value leakage as unmanaged spend continues to rise. For organisations without unified S2P capabilities, total expenditure often grows unchecked. This translates directly to eroded margins and reduced profitability as competitors gain advantages through their more sophisticated spend management approaches.

The S2P journey represents a strategic choice about the organisation's future. Those who embrace this transformation—selecting platforms designed specifically for comprehensive spend management rather than adapted from other purposes—position themselves for sustainable, profitable growth in an increasingly competitive landscape. Those who delay, or choose solutions that don't facilitate cross-functional collaboration, find themselves at a growing disadvantage as the capabilities gap widens.

For organisations just beginning to explore S2P, now is the ideal time to leapfrog legacy approaches and implement a solution that supports long-term digital transformation objectives. For those with existing but limited S2P implementations, evaluating whether the current solution can truly scale with the ambitions of the business – which could be the difference between incremental and transformative growth.

Looking at the business landscape ahead, leaders face a critical inflection point: the question isn't whether they can afford to invest in comprehensive source-to-pay transformation, but whether their organisations can survive without it in an increasingly AI-driven competitive environment.

The answer will shape the organisation's competitive position and growth trajectory for years to come.
