I run a software company. I purchased a software teamviewer from germany. This software is used for giving support to our clients. The payment has to be done in euro. When i contacted the main branch, as suggested by my home branch, they are telling to have a import export license. I purchase a software once in a year, why there is need of this license. I also purchased this software in jan.2016, but at that time there was no need of this license.
