This paper uses Spanish firm-level data to analyze the difference in the destination and variety-portfolios among service exporters. As for manufacture exporters, there is heterogeneity in the value of exports, the number of destinations and the number of varieties supplied among service exporters. However, compared to manufacture exporters, service exporters have a higher number of destinations and the number and value of transactions play a major role in explaining the evolution of aggregate exports.

Key words: services, exports, firm-level data, heterogeneity.
