Of course, if you apply for a project, you must first submit the plan for applying for the project. There is a budget for this project in the plan. And the project is to evaluate the whole project. Then I went offline. After the evaluation, including the budget. Budget is the cost and investment needed to complete this project. Therefore, the encounter includes income and expenditure. And this budget is the cost calculation before the start.
