The notion that differences in national culture influence international buyer-seller relationships (and, indeed, all aspects of international management) is not only held as true but also axiomatic. This study questions the degree to which cultural differences impact upon buyer-seller relations for seven key dimensions using Hofstede's indices of culture. Via two stages of data collection using two methodological approaches (seven interviews and 322 useable responses from a mail survey), the impact of culture on international buyer-seller relationships was examined. The study's findings identified little evidence to support the popular idea that culture exerts a significant influence on international business relationships. Instead, the findings suggest that some managers perceived factors such as communication/language barriers, political barriers, geographic distance, economic factors, industry barriers, time differences, technology barriers, legal differences and infrastructure barriers as being more likely to have a greater impact on cross-national relationships.
