What Is Source-to-Pay? +Benefits of S2P Process Automation

Organizations often waste resources due to inefficient spending during the sourcing & procurement processes. McKinsey suggests that most organizations waste up to 4 percent of their total external spend on high transaction costs, inefficiency, and non-compliance. Implementing a digital source-to-pay (S2P) application helps efficiently manage an organization’s spend by up to 50%, driving an additional 31% in total savings.

In this blog, we explore how source-to-pay applications are a one-stop solution to streamlining strategic sourcing and procurement.

What Is the Source-to-Pay Process?

The procure-to-pay (P2P) process begins with purchase requisition and ends with the payment of goods via accounts payable. However, when you bring strategic sourcing into the scenario, there is a tightly integrated source-to-pay (S2P) process that allows procurement leaders to manage maverick spending, sourcing, and contracting for higher efficiency.  

Stages of the S2P Process

The source-to-pay process includes the following stages:

S2P Process Steps

Due to varying business requirements, the source-to-pay process varies across industries. But the general S2P framework consists of the following nine steps: 

1. Demand identification

The first step is demand identification. Procurement leaders identify a need for goods and services and better pricing opportunities.

2. Sourcing

You can automate the sourcing process using an e-sourcing application. This solution handles large data sets to derive actionable insights from historical spending and market trends. Based on the organizational goals, potential vendors are identified, evaluated, and onboarded. 

3. Bidding

In this step, RFx documents, including the request for information (RFI), request for quote (RFQ), or request for proposal (RFP), are prepared, reviewed, and distributed to the potential suppliers.

4. Review & reward

The RFx responses are reviewed, and a winner is selected based on their suitability.

5. Contract negotiation & management

Post selection, the supplier is moved to the vendor management database, and contract terms and pricing negotiations begin. Once both the parties agree upon the contract terms, it moves to the signing stage. 

After contracts are signed, vendors are retained for the duration of their contract lifecycle and then long enough to comply with tax-related and company-related document retention policies.

6. Purchase order

Post contract signing, there is a transition to the procurement process, and a purchase order is created for the selected supplier.

7. Invoice processing

The accounts payable team receives vendor invoices and is responsible for the entire e-invoicing process, from processing invoices, getting approvals, and generating accounting reports.

8. 3-way matching

A three-way match is suggested once an invoice is received. The accounts payable team compares the purchase order, the goods receipt, and the supplier’s invoice before approving the invoice for payment. A 3-way match helps determine whether the invoice should be paid partly or entirely.

9. Payment

The accounts payable team makes and reconciles payments to conclude the source-to-pay process, keeping suppliers informed about the status of their payments.

Challenges in Source-to-Pay Automation

S2P is a complex process, and the absence of a digital S2P integrated application suite can pose these three major challenges:

1. Non-compliance

Corcentric research suggests that S2P processes have around 50% value leakage due to a lack of compliance. Organizations use multiple, disparate systems leading to decentralized compliance, making it difficult to maintain transparency in the overall process. 

2. Poor Data Visibility

It becomes difficult to maintain data visibility for the complete process unless there is an automated flow of data from one application to another to avoid any gaps.

3. Poor Collaboration

Collaboration becomes a challenge in the case of different applications as the solutions are configured by different people at different time frames, leaving scope for optimization but not collaboration. 

5 Benefits of S2P Process Automation

Source-to-pay automation will reduce maverick spending, minimize supplier risk, and streamline the entire S2P process. Digital transformation of the S2P cycle can help organizations maximize ROI and build a robust supplier network.

Here are five key benefits of digitizing the S2P process:

1. Risk diversification & minimization

Most organizations were exposed to supplier risk during the pandemic. Post this; organizations focused on building resilient supply chains and diversifying the risk by creating a robust network of suppliers. S2P automation provides a single source of truth and empowers the sourcing team to drive higher value from digital procurement and strategic sourcing processes. It further helps in building a collaborative relationship between all the stakeholders.

2. Increased compliance

The automated source-to-pay process follows a guided buying approach to ward off any contract or policy violations before they even happen. Source-to-pay solution guides the user through the purchase requisition process providing value by ensuring off-contract spending is curbed, and the buyer is guided to the correct suppliers, products, and services.

3. Cost savings

Automating repetitive manual tasks saves time and unlocks savings on your spending budget. According to Ardent Partners, organizations that leverage spend analysis directly into their sourcing projects can save an average of 24%- 41% more per project, while eliminating sourcing gaps can reduce savings leakage up to 38%.

4. Seamless technology integration

A tightly integrated source-to-pay suite enables a seamless workflow across the S2P lifecycle by inter-connecting all the modules and ensuring consistent data flow. Procurement teams can easily plug-in data, maintaining the ease of information flow. 

5. Higher user adoption

Organizations can only reap the benefit of digitizing the S2P lifecycle provided a large number of users feel comfortable being a part of this technological change and modify their behavior. 

Implementing a digital adoption platform such as Whatfix alongside your S2P solution can come in handy to increase user adoption. Whatfix offers contextual in-app guidance, multi-format self-help content, and intuitive change management capabilities to drive adoption and help you scale your technological changes.
