Milkman

This is an app to help deliver milk packets.

You can add new customers and assign credits to them. You may keep track of the number of credits they have and replenish them at the end of every month.

It gives the added flexibility of changing the number of packets on some particular day. You can also send a different distributor.

The customer can also place a barcode corresponding to their name outside so that the distributor can scan it.
