Can I use this as food delivery dispatch software for my own drivers?

Yes, through WhatsApp. Set up your riders under Settings → Riders & dispatch groups, with a group for each crew if you run more than one. On the orders board pick the rider and press Out for delivery, and that crew's group gets a ticket with the building, the unit, the map pin, the phone and the amount to collect. The ticket carries a one tap link that marks the order delivered from the road, and it works for twelve hours for that one order only. The customer's message names the rider. The Orders & delivery tab in the docs has a guide called Set up your riders and their dispatch groups.
