In a ranking established by the British magazine SupplyChain (BizClik Media Group), SAP Ariba tops the Top 10 digital platforms covering the entire chain Source-to-pay, or S2P. It is ahead of the solutions of Coupa and the French publisher Ivalua. The authors of this ranking recall that the S2P chain encompasses the processes of upstream sourcing, consultation and contractualization, management of requests, orders and receipts, then downstream invoicing-payment. In addition, there are the cross-cutting processes of managing the function, in particular for the analysis of expenses and the monitoring of the performance of purchases and suppliers. Sap's main competitor, Oracle occupies fifth place, between Jaggaer, fourth, and Zycus. Solutions from Medius, Gep, BuyerQuest and Xelix complete top 10.
