I am working with a starting Indian development shop, and even though it is challenging sometimes, and we're still trying to make it work, answers like this about last months' bill really make my day :)
From my provider: "payment: I dont know what the best way to bill for the last month is. Since various people jumped on various tasks at various times. Why dont you decide on the value of delivered items. If its more than zero we are making progress!"
