Before starting to outsource to a company in Romania, there are a lot of questions that should be answered about the possible partner company: if there is enough resource, knowledge and reliability; if the foreign company's organization is compatible; how the communication will flow; how the structure of the project will be set up; how the financial and legal aspects will be clarified and so on.
There are no generic answers to those questions but I can emphasize some interesting things and present some conclusions based on real-life experiences. I recorded some observations on this in an article on http://geekswithblogs.net/mtex/articles/72776.aspx.
