Hello,
I have some questions about the documents to attache to the tender application:

1. Tender form:
In the Supplier's ID part, what do you mean with "Seat" and "ID" Numbers.
Also, in part 2.c, What do you mean by TAX no.?
The contact person is someone at the bank or the contact person at the company responsible of the tender?
