到捷克货物的款项问题请教，不可以T/T 么？

请问各位知道的外贸大神。捷克这个国家是不是不允许t/t ，只能信用证，而且他要120天信用证？ 120天肯定不可能，请问我们该怎么？ 说他们国家不允许预付款，请问有过这个国家货的朋友么？谢谢了，着急！ many thanks for your help and patience and understanding to specific problems of this public bid which had to be once cancelled and when opened again you understand my strategy offering machine guiding us to the??victory!! you will see, that based on this bid we can sell more in future here because other schools are started receiving money as well and they can buy only throughout public bid purchase system we he already started procedure of l/c opening. as you may not know??from the past czech republic??- czech state - is not granting any down payment and payment term for whole delivery towards us as supplier is effected in 60 days from the date of machine commissioning what means from the date when we hand over all machines and equipment to the customer by protocol signed by representative of the buyer and representative of our company. 1/ your machines are a part of big deal with czech statr – delivery for tchools and payment term from the state is 90 days from the date when we hand over machines to them. by law there is no down payment allowed – this term is valid for all contracts with czech republic. 2/ for such case our bank will open an irrevocable l/c deffered by 120-130 days only because there is no other chance.
