What does an accelerated procurement process look like?

With new technologies and capabilities broadening the scope of what's possible in procurement, the shift toward Source-to-Pay automation is inevitable. 

In this guide, we’ll take a look at the transformative power of S2P automation, which can provide procurement and finance leaders with the power and insights to streamline workflows, enhance decision-making, and optimize overall procurement processes.

In this guide, you’ll learn:

  • What Source-to-Pay automation is, and how it can drastically improve procurement efficiency
  • The difference between Source-to-Pay and the Procure-to-Pay process
  • Common challenges faced by procurement teams in non-automated environments
  • How S2P automation is evolving into procurement orchestration, enabling more flexible, user-centric, and integrated procurement strategies with Zip

What is Source-to-Pay (S2P) automation?

Source-to-Pay refers to the comprehensive process that includes sourcing, purchasing, receiving, paying for, and accounting for goods and services. S2P automation integrates these activities through advanced software solutions, enabling businesses to improve efficiency, reduce costs, and enhance supplier relationships.

Source-to-Pay automation encapsulates all stages from the initial sourcing of potential suppliers to the final payment, encompassing strategic sourcing, contract management, purchase requisitions, purchase orders, invoice processing, and payment processing. By automating these steps, companies can significantly reduce cycle times, minimize manual tasks, and ensure a seamless flow of data across the procurement lifecycle.

Source-to-Pay vs. Procure-to-Pay automation

While both Source-to-Pay and Procure-to-Pay (P2P) are crucial components of the procurement spectrum, they cater to different stages of the procurement process. The Procure-to-Pay process covers the point of order through payment, focusing primarily on transactional phases of procurement such as purchase orders and accounts payable.

S2P, however, offers a broader scope than the P2P process, including the upstream activities of sourcing and strategic sourcing, which are critical for establishing supplier relationships and setting procurement benchmarks. For a deeper understanding, refer to Zip's detailed analysis in our definitive guide on procurement automation.

Top Source-to-Pay challenges

While Source-to-Pay is a practical, userful, and popular strategy for sourcing and completing procurement tasks and organizations at all sizes, there are several challenges that can limit the efficiency of non-automated S2P processes.

  1. Tedious manual tasks: Activities such as evaluating contract terms, running sourcing events, and managing RFQs and RFPs are highly time-consuming when done manually. These tasks, prone to human error, can lead to inconsistencies and delays in procurement cycles.
  2. Increase error risks: Manual data entry in processes like invoice processing and vendor management increases the risk of errors, which can affect spend analysis and financial planning.
  3. Complex processes: The intricate details involved in regulatory compliance, supplier risk management, and contract lifecycle management can overwhelm traditional systems, leading to inefficiencies.
  4. Non-digitized processes: A lack of digital tools can slow down the sourcing process, supplier onboarding, and risk management, impacting overall process efficiency.
  5. Over-engineered systems: Many S2P systems are overly complex. They focus heavily on features like catalogs and e-auctions that may not align with the real needs of procurement teams. This complexity can hinder adoption and operational efficiency.

As Nick Heinzmann, Head of Research of Zip put it in his Margin Makers newsletter: “...the 2020s approach to source-to-pay will be bottoms-up, not top-down. It will emphasize first and foremost the ease of navigating and adopting procurement processes. And these processes will be built on a flexible, open platform that allows for cross-system integration and continuous refinement of workflows.”

That’s one of our core values here at Zip.

By transitioning to a more flexible, bottom-up approach, Zip aligns with the future direction of S2P—transforming procurement into a process that is not just about automation but about orchestration. With Zip, businesses can anticipate a procurement environment that is not only efficient but also adaptable to the changing dynamics of global supply chains and market demands.

Top benefits of Source-to-Pay automation

Of course, there are a multitude of benefits to an automated Source-to-Pay process, addressing many key challenges procurement teams encounter in their daily workflows. With automated source-to-pay software, you can:

Improves ROI

Automating the S2P process drastically cuts down on processing times and administrative costs, allowing companies to reallocate resources to more strategic initiatives. This optimization leads to a better return on investment and cash flow by maximizing cost savings and forecasting, enhancing the overall value obtained from procurement activities.

Reduces human errors

By minimizing manual data entry and automating key procurement tasks such as spend analysis and invoice processing, S2P systems significantly reduce the likelihood of errors that can lead to financial discrepancies and procurement inefficiencies. Have you ever seen misappropriated supplier information? Automation can keep data modules consistent and accurate.

Eliminates tedious manual tasks

Automation liberates procurement professionals from repetitive low-value tasks such as data entry, manual approval routing, and document tracking. Integrating your e-procurement solution with your ERP can speed up the procurement cycle and also allow teams to focus on higher-value strategic sourcing and supplier relationship management and pricing negotiations.

Enhances visibility

S2P automation provides a centralized dashboard that offers real-time insights into procurement activities, spend management, and supplier performance management. This increased transparency aids in better decision-making and ensures compliance with company policies and external regulations.

Increases collaboration

Integrated S2P platforms facilitate seamless communication between procurement, finance, and other stakeholders. This collaboration is necessary for aligning procurement strategies with broader business objectives and ensuring cohesive action across the organization.

Reduces complexity and confusion

Automated workflows lead to standardized procurement processes, reducing the complexity and confusion often associated with managing multiple suppliers and contracts. This simplification helps streamline operations and reduces the risk of procurement bottlenecks.

Source-to-Pay automation and Procurement Orchestration

Zip is the world's leading Procurement Orchestration platform. But what exactly is procurement orchestration?

Procurement orchestration centralizes the coordination of all workflows, information, and people involved in the procurement process. This integration spans across all related systems, ensuring that every aspect of procurement from supplier management and sourcing to final payment is harmoniously aligned.

Evolving into true procurement orchestration

S2P automation is rapidly evolving into a more comprehensive model of procurement orchestration. This evolution marks a shift from isolated, function-specific process automation to a holistic, integrated approach that encompasses all elements of procurement.

In line with Nick Heinzmann’s take on the evolution of procurement tech, the future of S2P is a move away from rigid, over-engineered systems towards a flexible, user-centric approach. This transition allows for:

  • User-centric designs: Systems designed with the end-user in mind promote greater adoption and satisfaction among procurement teams. They prioritize ease of use, flexibility, and customization.
  • Flexible platforms: Instead of mandating top-down, one-size-fits-all solutions, flexible platforms allow businesses to tailor their procurement software operations to specific needs and market conditions. This adaptability is crucial for staying competitive in dynamic economic landscapes.
  • Cross-system integration: By integrating IT, legal, compliance, and financial planning into procurement workflows, companies can create a seamless interdepartmental collaboration. This holistic approach not only simplifies business processes but also ensures that all procurement decisions are well-informed and strategically aligned.

By focusing on procurement orchestration, Zip's platform embodies the future of procurement, transforming it from a series of isolated tasks into a strategic, cohesive operation.
