We have recently published a research paper in which we examine the factors affecting the adoption of electronic invoicing. External pressure from customers (public and private) emerged as one of the key factors from the survey data. Other statistically significant factors were: organizational readiness, perceived benefits and the so called “bandwagon effect”. Our research paper can be found at http://www.hse.fi/NR/rdonlyres/5D5F6A47-4FFD-4CD9-A09A-9EB21 78D0E71/0/PenttinenandTuunainen2009.pdf
