We are a takeaway with our own drivers. Is this an EPOS for takeaway that also gives the driver a ticket?

Two things work together here. A walk in takeaway is a counter sale on the POS, with a receipt and a kitchen ticket. A delivery comes in on your ordering page, lands on the orders board, and when you press Out for delivery the riders' WhatsApp group gets a ticket with the address, the map pin, the phone and a one tap link to mark it delivered. So an EPOS system for takeaway and delivery is really two doors into one kitchen, both on the same kitchen screen. Set the riders' group under Settings → WhatsApp connection & groups. The Orders & delivery tab in the docs covers dispatch.
