Add inventory tracking for optional products, which is managed from a central database. We offer a variety of fast food dishes (approximately 25 dishes) and serve 4 different fruit juices as additional choices for all our meals. The fruit drinks are outsourced and mostly take a while to be restocked. Having a central point for managing inventory for options will be very helpful, as it eliminates the need to delete and re-add options from each product when they become available.
