Your client's customer calls to ask. If nobody can answer, it is your client who loses the contract. Sell them the ability to answer on the spot.
When the vehicle enters the customer's site, the real time is recorded.
Time spent inside the customer is measured, with no argument.
With RouteOS the run is organised and progress is visible.
History is the evidence when the customer says nobody showed up.
With WhatStar the person waiting can be notified by WhatsApp.
How many deliveries arrived on time and how many didn't.
Exact words you can use on the visit. No jargon.
“When your customer calls asking where the order is, you answer in ten seconds without calling the driver.”
“And if they claim the truck never arrived, you have the exact time it entered and left.”
“With that you stop arguing and start showing.”
You resell under your own brand. This is who it works for, and with what argument.
Those delivering to shops and supermarkets with time windows.
Where reliability is the reason they get hired.
Those answering to a demanding shipper.
Technicians and crews with scheduled appointments.
By sharing a link that opens in the browser with no username or password, and that expires when you decide. The client follows the delivery and stops calling.
Yes, with the zone entry and exit report: it marks the arrival time and how long the vehicle stayed inside the client's site.
Yes, with tasks assigned to the driver that are closed with the signature of whoever received the goods, with the time.
That is exactly what it is for: the report shows how long the truck waited at each client, and that figure is what carries the negotiation.
It is what your client needs in order not to lose their own contracts.
