For middle-market and large private-sector organizations, making a best-of-breed e-procurement decision used to be easy. There was Ariba (and then Coupa) and everyone else. But in recent years, the market has become much more fragmented – even among specialist providers – and an e-procurement shortlist today will not look anything like a shortlist from even the last Wave or Magic Quadrant. But here's the even more fundamental challenge: There is not one e-procurement market! This Spend Matters research brief examines 3 different types of best-of-breed procurement providers that are a proxy for 3 different categories of e-procurement solutions: Coupa, Ivalua and BuyerQuest. Each vendor represents different philosophies and brings a unique solution orientation and strength – as do their peers.
