Where, how and when should I justify the costs in the budget? Are the costs not justified in the Czech Annex of the Application form?

In the first round, there is no need to justify costs on the Application Form. If the project advances to the second round, you will be required to complete and submit an updated Application Form, in which we will ask you to complete the budget again , including a justification. The justification must be described in such a way that it clearly indicates what these costs will be used for and what purpose they serve.
