What are the most important steps of the Source to Pay process?

The S2P process consists of several basic steps. Let's start with the step "0", it is the definition of purchasing organisation structure and processes for the proper implementation of the entire process. This step is a starting point, allowing, among other things, for the standardisation of the processes, the best use of available resources and better control of contract performance and relationships with suppliers. Purchasing organisation structure and processes should be adjusted to the business objectives of the company.

Having completed step 0 we can start selecting suppliers. Here it is worth paying attention to the following important issues:

  • First, suppliers should offer products with quality and level of innovation meeting the needs of the company and maintaining its reputation – optimisation of the value.
  • Secondly, products should be properly priced – optimisation of the cost.
  • Thirdly, suppliers should meet the company's expectations in terms of finances, management level, propensity for development or openness to change.

All of these issues are subject to negotiation, whose aim is to select preferred partners.

S2P and P2P - the next steps in the process

The next steps of the S2P process are placing orders, collecting deliveries and settling invoices. This part of the process is also known as P2P. When accepting the product or receiving the service, checks are made. They are intended to determine whether the delivered goods are in accordance with the order, meet the buyer's quality requirements and whether they are valued in accordance with the terms of the contract.

The final step of the S2P process is to receive invoices and make payments to sellers. After making transfers, the cycle ends.

Of course, the economic reality forces enterprises to continuously improve tools supporting the purchasing process. Many companies use advanced IT systems. They support buyers in their daily work - for example, they allow for better preparation for negotiations. Systems also support the management when making key decisions for the company.
