Frequently asked questions about Source to Pay (S2P)

What is Source to Pay?

Source to Pay (S2P) is a comprehensive process that begins with supplier management and ends with the procurement, acquisition, and payment of goods and services to improve process efficiency from the detection of a need to the reconciliation of invoice payment through automation. It is a strategic approach that will improve interdepartmental communication and communication with business partners.

What is supplier approval and why is it key in Source to Pay (S2P)?

Supplier approval is the process of evaluating, validating and documenting that a supplier meets the requirements defined by the company before doing business with them. In a Source to Pay approach, it is key because it reduces risks, avoids unexpected sign-ups and improves traceability from sign-up to purchase, receipt and payment.

What benefits does a Source to Pay (S2P) platform bring to Procurement and Finance?

An S2P platform helps standardise processes, reduce manual tasks, improve traceability and increase spending visibility. It also facilitates coordination between Procurement, Finance and IT, minimising operational friction and improving process governance.

How does a source-to-pay platform integrate with ERP and existing systems?

It is typically integrated with the ERP to synchronise key data (suppliers, cost centres, orders, invoices, statements) and avoid duplication. The aim is to maintain operational continuity, respecting current processes, but providing automation, control and traceability at critical points.

Does SERES' S2P platform integrate with my ERP and my current processes?

Yes. The usual approach is to integrate with the ERP and coexist with existing systems so that standardisation and Source to Pay processes maintain operational continuity, avoiding duplication and improving data control and end-to-end process control.

What is the difference between S2P and Procure to Pay (P2P)?

In general terms, P2P tends to focus on the operational phase (request, order, receipt and invoice/payment), while S2P broadens the scope by also incorporating previous stages of purchasing (such as sourcing/pre-management), to achieve a more end-to-end approach with greater control and alignment.
