Planning for Software Implementation? Your 2026 S2P Initiative Depends on It

Introduction

Most procurement teams understand the value of Source-to-Pay (S2P) transformation. Whether you're targeting increased visibility, stronger compliance, or operational efficiency, the business case is often clear and compelling. 

The less-acknowledged truth, however, is that none of these benefits materialize without a well-executed software implementation. While selecting the right technology is important, it is the implementation strategy that ultimately determines whether a transformation delivers lasting value or falls short of expectations. 

don't assume the vendor owns it

A common misstep that organizations take is assuming their software vendor will manage the implementation. While configuration tools and technical support may be provided, vendor-led approaches often prioritize system functionality over organizational readiness. The result? A solution that users resist, business units don’t trust, and one that falls short of your original objectives. 

Instead, implementation should be owned by a partner who understands both the software and your operating model. Demanding more than just active modules, a successful rollout requires thoughtful design, cross-functional alignment, change management, and clear success criteria. 

your roi depends on execution

When organizations embark on a transformation initiative, the investment is ultimately vested in the outcomes, not the software. Despite this, too many organizations gloss over the implementation phase or underestimate the effort required to achieve those outcomes. If the solution is poorly scoped, rushed to meet arbitrary go-live dates, or lacks the internal resources needed for success, the projected ROI can quickly evaporate. 

Smart teams recognize that implementation is where ROI is made or lost. A strong design alone is not enough; value is unlocked when that design is executed with the right project structure, realistic timelines, effective stakeholder engagement, and a proactive approach to change management. Without these foundational elements in place, even the most promising business case can stall before benefits are realized. 

budget and scope: don't leave to chance

When evaluating software, it is common to assume that discussions around implementation should occur after the fact. However, without a clear understanding of the nature of implementing the proposed modules, supplier enablement, and integration complexities, you risk underestimating both the timeline and the total cost. 

Scoping should come early with input from your implementation partner, informed by real data and organizational priorities. Key questions to consider: 

  • Will you roll out globally or start with a pilot region? 
  • Are you planning a phased approach across the S2P cycle or a big-bang deployment? 
  • What legacy systems or third-party tools will require integration? 
  • Is there adequate internal capacity to support configuration, testing, change management, data cleansing, and data management? 

get it right from the start

If your organization is considering a 2026 source-to-pay initiative, implementation planning should start now. At Optis, we help clients bridge the gap between business case and execution by providing the following support:

  • Clarifying scope and timeline before budget approval 
  • Aligning stakeholders across procurement, finance, IT, and legal 
  • Designing for adoption, not just configuration 
  • Building implementation readiness into the early phases of transformation 

Organizations that treat implementation as a core strategy, rather than an afterthought, are far more likely to deliver on their goals. If you’re preparing for a 2026 launch, the decisions you make now will define your outcomes later. 

conclusion

Your software implementation is the critical first step that sets the stage for long-term value. Approach your implementation strategically rather than leave it to default assumptions, unrealistic timelines, or under-scoped budgets. With the right planning and the right partner, you can move into 2026 with confidence and clarity.
