Recommended approach
We recommend following the below sequence when you do your budget
Review and finalise your permanent staff cost budget for the department since this is usually the biggest cost for the departments.
Then if you wish to also capture casual costs or wish to capture non-people costs at detailed level, you can use project templates to do so
Alternatively, you can capture the non-people costs budget at high-level instead of doing it at project level
If you wish to request Capex budget, you can do that via Project level
Once you have done individual template inputs, you can review your overall budget and compare it with the budget envelop before finalising it
