Of course, any export/import business requires time for documents preparation and finding new potential clients and customers. Despite all these, opening a business is easy these days, but making it profitable is difficult even with all the tools that have been afforded to us in the last 10 years online to organize. With the internet as the biggest competitor, clients are constantly being bombarded with cheaper prices cutting out our margins. That being said the right kind of customer will be loyal to you was long as you have a reasonable price. Many might not see that as loyalty but the dollar speaks for itself. Basically it all comes down to finding something that one place doesn't have (and needs) and bringing it there. "All one must do to make gold is bring water to the desert."
No! If you are already a seller with the license, it takes about 5 minutes (!) to become a verified seller on Export Portal. All you have to do, is to register and to go through the accreditation. As for me, I registered, and after an hour I already had some orders. Also, if you want to do business faster, you can use B2B feature and find your partner for constant and profitable business relationship. Good luck!
