Understanding Source to Pay: Process, Benefits, Challenges, Best Practices and More

Between the complexities of supplier management, unpredictable market dynamics, evolving regulations, and the constant pressure to optimize costs, managing the procurement process from source to pay can feel like an uphill battle. You may face numerous challenges that hinder the effectiveness and efficiency of your procurement function.

But fear not, because the practice of Source to Pay can save the day.

Source to Pay (S2P) is an end-to-end procurement process that encompasses all activities from identifying and selecting suppliers to purchasing services and making payments.

Not sure where to start?

Let's dive into the nitty-gritty of Source to Pay, including a step-by-step process.

‍

What is the Source to Pay?

Source to Pay (S2P) refers to the integrated process of managing all activities involved in your organization's procurement cycle, from identifying and selecting suppliers to processing invoices and making payments. 

It encompasses strategic sourcing, contract management, purchasing, receiving, invoice reconciliation, and supplier payments. The goal of S2P is to optimize your procurement function, reduce costs, improve supplier relationships, and ensure compliance.

The impact of an ineffective Source to Pay process can be significant:

• Delays in the procurement timeline
• Negative impact on procurement performance and outcomes
• Reduced team productivity and unsatisfied internal stakeholders
• Lack of visibility and control over spend

While it's not possible to eliminate all challenges associated with procurement, when you proactively identify risks and implement an end-to-end Source to Pay process, you can mitigate potential issues and drive continuous improvement in your procurement function.

Why is Source to Pay important?

By investing in S2P, you can drive cost savings, mitigate risks, improve efficiency, strengthen supplier relationships, gain spend visibility, and ensure compliance.  

Here's a closer look on why Source to Pay is important:

1. Better Procurement ROI:

When you have a well-managed S2P process, you can leverage spend analysis, strategic sourcing, and contract management to negotiate better terms with suppliers, consolidate spend, and reduce maverick purchasing. This leads to significant cost savings that directly impact your procurement ROI.

2. More resilient and risk-aware procurement function:

Source to Pay provides you with end-to-end visibility into the procurement process, enabling you to identify and mitigate potential risks proactively. As you conduct thorough supplier assessments, monitor supplier performance, and ensure contract compliance, you can minimize the risk of supply chain disruptions, quality issues, and reputational damage. 

4. Strategic supplier relationship management:

Effective Source to Pay practices  encourage better collaboration and communication with your suppliers. When you provide a centralized platform for supplier information, performance metrics, and interactions, you enable your procurement teams to build stronger partnerships with key suppliers. 

These benefits translate into tangible business outcomes, such as increased profitability, improved cash flow, and enhanced customer satisfaction.

Types of common Source to Pay challenges to watch out for

While Source to Pay offers numerous benefits, you may face various challenges in implementing and managing the process like change management, data quality, lack of spend visibility and more. 

1. Lack of spend visibility: 

Without a centralized view of procurement spend across your organization, you may struggle to identify savings opportunities, manage suppliers effectively, and make informed decisions. Fragmented data sources, inconsistent coding, and manual processes can hinder spend visibility, leading to inefficiencies and missed opportunities.

2. Resistance to change: 

Implementing a new Source to Pay process often requires significant changes to existing workflows, roles, and responsibilities. You may encounter resistance from employees who are accustomed to traditional ways of working or fear losing control. Overcoming this resistance requires effective change management, communication, and training to ensure buy-in and adoption.

3. Supplier onboarding and management: 

Onboarding new suppliers and managing existing ones can be a time-consuming and complex process. You need to collect and verify supplier information, assess their performance and risk, and ensure compliance with policies and regulations. Inefficient supplier onboarding and management processes can lead to delays, errors, and exposure to supply chain risks.

4. Maverick spending: 

Maverick spending, or purchasing outside of approved contracts and processes, can undermine the benefits of Source to Pay. Employees may bypass procurement policies and procedures for various reasons, such as perceived convenience, urgency, or lack of awareness. 

What are the steps involved in the source-to-pay process?

The source-to-pay process typically includes the following steps: spend analysis, sourcing, contract management, procurement, receiving, invoice processing, payment, and supplier performance evaluation. 

‍

These steps form a comprehensive cycle that manages an organization's purchasing activities from identifying spend patterns to evaluating supplier performance.

Let’s have a closer look: 

Steps involved in the source-to-pay process:

1. Spend Analysis: 

This initial step involves a comprehensive review of an organization's historical spending data. The goal is to identify spending patterns, recognize opportunities for cost savings, and categorize expenses and suppliers. This analysis provides valuable insights that inform strategic decisions in subsequent steps.

2. Sourcing:

 In this phase, the organization identifies potential suppliers capable of meeting its needs. The procurement team creates and distributes requests for quotations (RFQs) or requests for proposals (RFPs) to these suppliers. Once responses are received, they are carefully evaluated based on various criteria such as price, quality, and delivery terms. Negotiations then take place to secure the best possible terms and conditions. Finally, the most suitable suppliers are selected.

3. Contract Management: 

After selecting suppliers, contracts are drafted and finalized. These contracts outline the agreed-upon terms, conditions, prices, and service levels. Once signed, these contracts are stored in a centralized repository for easy access and reference. The system is set up to generate alerts for contract renewals and expirations. Throughout the contract period, supplier performance is monitored to ensure compliance with the agreed terms.

4. Procurement: 

This step begins with the creation and approval of purchase requisitions within the organization. Once approved, these requisitions are converted into formal purchase orders. These purchase orders are then sent to the selected suppliers. The suppliers acknowledge receipt by sending order confirmations, which are processed and recorded in the system.

5. Invoice Processing and Payment: 

Suppliers submit invoices for the goods or services provided. These invoices are compared against the original purchase orders and receiving records to ensure accuracy. This three-way matching process (purchase order, receipt, and invoice) helps prevent errors and fraudulent charges.

6. Supplier Performance Evaluation: 

The final step involves evaluating supplier performance based on factors such as uptime and downtime, quality of services, responsiveness, and adherence to contract terms. This evaluation informs future sourcing decisions and helps in maintaining a high-quality supplier base.

Difference between procure to pay and source to pay

While Procure to Pay (P2P) and Source to Pay (S2P) are often used interchangeably, there is a subtle but important difference between the two. 

Procure to Pay focuses on the transactional aspects of procurement, starting from the point when a purchase requisition is raised and ending with the payment to the supplier. 

On the other hand, Source to Pay encompasses a broader scope, including strategic sourcing activities that occur before the transactional procurement process begins. 

In simple words, Source to Pay covers the entire procurement lifecycle, whereas Procure to Pay is a subset of the Source to Pay process.
