NSS suggestions

Some items are bought in bulk and used up without being billed to the patient. Examples: the scan gel (comes in a 5 kg pack) and the covers medicines are given in. The hospital still needs to track the money spent on buying them. We need a simple way to record and report this expense. For example, an expense entry by category (scan gel, covers, other consumables) with supplier, date and amount, and a total by month.
