Answers to your questions about the Netherlands

Because the Dutch market judges a supplier quickly and on different signals than many others. Buyers here expect a clear proposition, direct pricing and no exaggeration, and they check whether you look established: a .nl domain, a Dutch address and phone number, a Chamber of Commerce number, real terms and conditions, and reviews they can find. A foreign company that skips those looks temporary, and being seen as temporary is what costs the first deals rather than the price.
