As an employer, can I buy international train tickets on a business account?
Business travellers can use the NS-Business Card. Your employees can use this card to travel on all public transport in the Netherlands, such as trains, buses and metros. It's also possible to book international train tickets on the NS-Business Card online. Payment is made later as specified by a detailed monthly invoice.
If you are interested, see ns.nl for more information or to order a NS-Business Card.
