I'm working in Road Construction firm. We purchases various items like Bitumen, Cement, Steel rodes. There is no problem in passing the Purchases of these items.But a quantity of these items are used in road making. so how should I record the consumption of these items as now they have decreased from actual stock ?
besides I haven't sell any of them to any third party, ??
