The customer has taken the morning off. The removals van is somewhere on the North Circular. The phone rings in the office and the question is the same one it was yesterday: where are they.
The driver should not be the one answering that. He is driving. So the phone in the cab does the work without being touched. When the van leaves the depot the first job on the list gets a message: on our way, here is the window. When the van is twenty minutes out by Google Maps traffic, the customer gets the twenty minutes message. When the van stops at the address, the customer gets the arrived message. None of those need a hand on the phone.
Proof of delivery is a photo. The driver takes one at the door, the boxes in the hallway or the sofa on the pavement. The photo goes to the customer within a minute with the time stamped on it, and a copy goes to the job folder with the job number as the file name. Same for pickups.
Addresses are the usual problem for removals. A new build with no number on the door, a farm with three gates. If a customer gives a what3words address it is passed to the driver's maps as a pin, and the message to the customer quotes it back so there is no argument about which gate.
The office sees all of it on one screen: every van, every job, the last message sent. Couriers get the same thing in a smaller shape, the DPD style message everyone is used to, from your own number and your own vans.
This is the kind of thing we build. It runs on the drivers' own phones and your own numbers. The office phone still rings. It rings less.
