The following paper presents results from a longitudinal study on the use of ICT for B2B-related business processes in large Swiss companies. In an empirical survey, 68 questionnaires were personally collected from procurement heads and sub-sequently analysed. The findings show that reduction of purchase prices is the top priority when goal-setting in procurement. Electronic orders and invoices are the business documents that are most often exchanged electronically between partners. Electronic exchange of invoices (e-invoicing) is a current key topic for over 70 % of the companies. Procurement heads sense a lack of supplier involvement which makes the realisation of balanced B2B solution scenarios difficult. The study shows that IT, without doubt, plays a significant role in everyday procurement, but that the expectations of IT are rarely completely fulfilled.
