Is it clear to the funder why you need the sums you asked for?
Do salary and space costs relate to levels of service? Have you explained why you need each worker? Did you get quotes for equipment?
Get your finance people involved in allocating running and management costs. Don’t forget to include outreach and recruitment costs. Budgeting makes activity credible. Funders will not believe you can reach people if you do not show you have thought through how to do it and how much it will cost. If you already have a resource already funded still include it as such – it shows you have thought about what’s needed.
