AMOA Source to Pay (S2P)

Your Source-to-Pay challenges
In an uncertain economic environment, purchasing management is becoming a decisive strategic lever. A purely “Cost Centric” approach is no longer sufficient, and organizations are faced with ever-changing regulatory challenges.
The fluidity of processesand themastery of datahave become essential to the internal and external transformation of organizations.
As experts in Finance Transformation Council, we recognize that optimizing the Source to Pay process is one of the key value-creation levers for finance and purchasing departments today.
You would like to :
- Adapt your purchasing function to new regulations (e-invoicing, CSRD, GDPR)?
- Transform your purchasing process into a real performance driver?
- Control and secure your data for better decision-making?
- Streamline your processes and optimize collaboration?
- Or simply digitize your source-to-pay chain?
Our vision of the Source-to-Pay process
Understanding the entire Source-to-Pay chain is essential to identifying the optimization and digital transformation opportunities that will generate the most value for your organization. Our expertise lies in our ability to understand this process in its entirety, identifying the interactions between each phase and the specific levers for improvement.
Source-to-Pay (S2P) refers to all the stages inherent in a purchasing management process within an organization, from the identification of a requirement through to supplier payment.
Within this framework, the activities of this process can be divided into 5 main phases, each presenting specific challenges that we master:
Sourcing
Identification, evaluation and selection of suppliers
Contractualization
Negotiating and formalizing commercial agreements
Procurement
Management of requisitions, orders and receipts
Billing
Processing, validation and posting of supplier invoices and credit notes
Payment
Execution of supplier payments in compliance with contractual and regulatory deadlines, accounting
Our integrated approach enables us to identify points of optimization in your current S2P chain, and to design solutions that break down functional silos, for better collaboration between Purchasing, Finance and Business teams.
Beware of P2P/S2P confusion: Unlike S2P, Procure-to-Pay (P2P) refers to a process that starts with the purchase requisition and ends with invoice payment. The Sourcing and Contractualization stages are therefore not taken into account.
Very often, the notion of P2P is used to describe an organization’s purchasing process, which can lead to the neglect of critical value-creation phases.
