Source to Settle (S2S) vs Procure to Pay (P2P)

For effective procurement and supply chain management, you can use one of the many models available. But the two most popular ones are the source-to-settle model and the procure-to-pay model.

‍

Both the source-to-settle and procure-to-pay models are essential in driving strategic procurement and supply chain optimization. By using either of these models or a combination, you can achieve improved cost savings, risk mitigation, and operational efficiency.

‍

In this article, we’ll dive into the details of what each of these models are, how they differ, and which one might be right for you.

Understanding source-to-settle

‍

The source-to-settle process is a comprehensive framework that encompasses the entire procurement lifecycle, from the identification of sourcing needs to the final settlement of payments.

‍

The source-to-settle process involves a series of interconnected steps, including sourcing, contract management, ordering, receiving, and invoice processing. 

‍

By streamlining and integrating these functions, you can achieve greater visibility, control, and automation throughout the procurement cycle. This can help you reduce the risk of errors and delays, enable more informed decision-making and strategic procurement initiatives.

‍

The source-to-settle model can transform procurement from a transactional function into a strategic driver of business success. By leveraging data-driven insights and automation, you can identify and capitalize on cost-saving opportunities, negotiate better contracts, and ensure compliance with internal policies and external regulations.

‍

Next, let’s look at the benefits of adopting the source-to-settle model for procurement.

‍

Benefits of source-to-settle

‍

By implementing the source-to-settle model for your procurement processes you can:

• Optimize sourcing and procurement processes, reduce maverick spending, and increase contract compliance. You can also leverage strategic supplier relationships for enhanced buying power.

‍

• Streamline procurement workflows, automated and digitize your procurement processes, and improve data visibility and reporting capabilities.

‍

• Proactively identify and resolve contractual and performance issues, improve compliance with internal policies and external regulations, and even mitigate risks arising from the suppliers’ side.

‍

• Collaborate better with your suppliers, increase transparency and trust with them, and improve supplier performance monitoring and feedback.

‍

• Make strategic, data-backed procurement decisions based on comprehensive spend analysis, procurement trends, and opportunities for optimization.

‍

• Foster a culture of innovation and continuous learning through ongoing process optimization, incorporation of stakeholder feedback, and industry best practices.

‍

By implementing the source-to-settle model, you can achieve a more strategic, efficient, and risk-averse procurement function.

‍

But to implement it, you must also understand the key components of the source-to-settle process.

‍

Key components of the source-to-settle process

‍

The key components of the source-to-settle process are:

‍

1. Strategic sourcing, which you need for spend analysis, category management, and supplier identification, evaluation, and selection. It also aids in the Request for Proposal (RFP) and negotiation processes.
2. Contract management, for contract creation, approval, storage, access management, performance monitoring, and renewal or termination.
3. Procurement requisition, which helps with requisition creation and approval, purchase order generation, and supplier order placement.
4. Goods and services receipt, for goods and services delivery, inspection and acceptance, and also inventory management.
5. Invoice processing, which is essential for invoice receipt, validation, approval, and payment authorization. It also helps with dispute resolution.
6. Supplier relationship management, which you need to evaluate supplier performance, collaborate with them, and even for supplier risk management.
7. Continuous improvement for process optimization, automation, data analysis and reporting, as well as stakeholder feedback and engagement.

‍

These core components of the source-to-settle model work together to maximize supplier relationship value, mitigate procurement-related risks, enhance operational efficiency and cost savings, and foster a culture of continuous improvement and innovation.

‍

Now let’s take a closer look at the procure-to-pay process.

‍

Understanding procure-to-pay

‍

The procure-to-pay process is an end-to-end workflow that encompasses the procurement of goods and services, from the initial request to the final payment. It focuses specifically on the transactional aspects of procurement, covering the steps from purchase requisition to invoice payment.

‍

By streamlining and automating these processes, you can achieve greater efficiency, reduced errors, and improved cash flow management. The procure-to-pay model leverages technology and data-driven insights to optimize purchasing decisions, enhance supplier collaboration, and provide visibility into spending patterns and budgets

‍

The procure-to-pay process centralizes procurement activities and leverages data-driven insights to help you negotiate better terms with suppliers, identify cost-saving opportunities, and ensure compliance with established policies and regulations. It also facilitates better visibility into your organization's spending patterns, allowing for more informed decision-making and strategic resource allocation.

Meanwhile, let’s highlight the differences between source-to-settle and procure-to-pay models.

‍

Difference between source-to-settle and procure-to-pay models

‍

The source-to-settle model and the procure-to-pay model are two distinct approaches to managing the procurement and payment processes. While they share some similarities, there are key differences between the two models.

‍

Choosing the right model

‍

When selecting between a source-to-settle and a procure-to-pay approach, here are the key factors to consider:

‍

Advantages of using technology and automation

‍

The integration of technology and automation into the procurement process can provide significant benefits like cost savings, increased efficiency, enhanced visibility and control, risk mitigation, and informed decision making.

‍

Let’s dive into how specifically technology can benefit each of the two models discussed above.

‍

Advantages of technology in source-to-settle

‍

The source-to-settle model can benefit from technology in the following ways:

‍

• You can optimize supplier contracts and negotiations by leveraging AI-powered supplier identification and evaluation, automated spend analysis, and category management.

‍

• You can streamline onboarding and off-boarding processes for suppliers through centralized supplier data and performance monitoring, and improved collaboration and communication.

‍

• You can proactively identify and mitigate supply chain risks through automated compliance checks and controls.

‍

• You can identify cost-saving opportunities and optimization initiatives by leveraging comprehensive spend analytics, reporting, and predictive insights for strategic decision-making.

‍

Advantages of technology in procure-to-pay

‍

Using technology can enhance the procure-to-pay model in these ways:

‍

• Reduce manual interventions and processing times via automated procurement workflows and approvals, and real-time tracking of purchase orders and invoices.

‍

• Improve compliance with internal policies and external regulations stemming from the tight integration with financial systems and ERP, and robust approval processes and audit trails.

‍

• Streamline supplier communication and information sharing, as well as implement supplier self-service capabilities for invoicing and payments.

‍

• Gain the ability to make informed, data-driven procurement decisions via comprehensive procurement data and analytics, which give you insights into spend patterns, trends, and optimization opportunities.

‍

While both the source-to-settle and procure-to-pay processes benefit from technology and automation, the advantages tend to be more strategic in nature for the source-to-settle process, focusing on sourcing, supplier management, and business intelligence.

‍

In contrast, the advantages of technology in the procure-to-pay process are more operational, centered on improving efficiency, financial controls, and data-driven decision-making.
