Overview

Why this workflow matters

The Source-to-Pay workflow is the backbone of every procurement organisation. It connects every step from the moment a need is identified — a production requirement, a stock replenishment, or an ad-hoc purchase — all the way through to payment. Without a structured S2P workflow, companies suffer from maverick spending, missed savings, compliance failures, and poor supplier relationships. Proconomy digitises and automates the full S2P cycle, giving procurement teams complete visibility, control, and speed — while AI agents handle the repetitive analysis, matching, and exception resolution in the background.
