Physical goods are easier to track than services, since the former have to go through a port. The UN has made great efforts to standardize goods data, but AFAIK they don't have services data. This is the data that this website is using: https://comtrade.un.org/ https://comtrade.un.org/. That said, the Harvard version of The Observatory of Economic Complexity, the Atlas of Economic Complexity (there is an MIT/Harvard rivalry here), includes services data: http://atlas.cid.harvard.edu/explore?country=231&product=undefined&year=2017&productClass=HS&target=Product&partner=undefined&startYear=undefined http://atlas.cid.harvard.edu/explore?country=231&product=und.... From the Atlas's website: "The raw trade data on goods are derived from countries’ reporting to the United Nations Statistical Division (COMTRADE). The trade data on services are from the International Monetary Fund (IMF) Direction of Trade Statistics database, via the World Development Indicators."
