First of all have an overview about the organization ( the persons who are engaged there ) to ensure whether it is working according in a sound system.
After that; focus on the major expenditures (revenue or capital) with the help of ratio analysis (so that you cover 80% of expenditure in amount and 100% of capital expenditure).
100% of capital expenditure is required to be checked because year after year the balances would be carried forward.
Small expenditure can be left if vouchers are properly prepared and sanctioned by the authorities.
