Graydrop's ability to integrate with other third-party systems and the flexibility of their scheduling engine make it a great choice. Their online ordering and inventory management capabilities are also impressive. Graydrop's online portal allows users to manage their schedules and create new ones from within the system. Users can also request deliveries via text message. I like how they allow you to schedule your own delivery times so that no one else has access to them at those specific hours. Also, when setting up an account, if there isn't enough time left in my billing cycle or after placing the order (as opposed to paying) then the customer gets notified immediately instead of having to wait until the next day.
