"A BSM platform functions alongside an ERP system, it does not replace it," Schouten clarifies. On the other hand, an ERP system is not suitable for all procurement activities. “An ERP is insufficient for the entire domain of Business Spend Management. Important elements of Sourcing and Contract Management are barely manageable in an ERP. Benefits in terms of risk management, compliance and cost savings will not be attained.”
In addition, the user experience of an ERP system leaves much to be desired. "An ERP excels at processing transactions and storing a lot of data," Schouten explains. "But little attention has been paid to the user experience. Moreover, an ERP contains a lot of static data which is not up-to-date. Exchanges with external systems are problematic which makes information enrichment difficult as well. A BSM platform operates in the cloud and is made for the flexible exchanging of data with other systems, including the ERP."
