We produce serialized coins and we put those coins in boxes of 25. We then take those boxes of 25 and place them in boxes of 100. Finally we take 5 boxes of 100 and put them in boxes of 500 coins. We will only sell the boxes containing 500 units but we need to track all boxes including their serialized coins. Can someone please shine some light? The idea is to have barcodes on the boxes so that when we are ready to sell a 500 coin box, we can quickly print a detailed list of all serial numbers.
