Software for ready-mix
Your terms price the waiting.
Concra times it.
Published rates run from £1.25 to £4.50 a minute once the free time is gone. Concra timestamps arrival, waiting, discharge start and discharge end on every load and puts them on the docket. Built for our own plant, running in our own lorries.

- Brett, Gallagher Free time in writing, then “additional costs as it determines, acting reasonably”. —
Taken from producers’ own published delivery terms.
The first three are invoiceable the moment you can show the minutes. The last one is a conversation with the site, and it is held by whoever has the timestamps.
02The proof
Four times on every load
On site. Waiting. Discharge start. Discharge end. Each one timestamped as it happens and carried onto the docket.
Weather at the delivery address is logged on arrival, then every hour for as long as the lorry is standing there. Concrete cures differently in sun and in rain, and nobody asks about the weather on the day.
The record stays with the load: times, address, weather.
03The chain
Order to invoice
Five steps. Four of them look after themselves.
-
Step 1
Order
The order goes in at the office: customer, delivery address, mix, time.
-
Step 2
Tablet
The driver sees the day’s loads on the tablet in the cab. Nothing to install.
-
Step 3
Position
The lorry leaves the plant — the order goes live. It reaches the delivery address — on site.
-
Step 4
Docket
Waiting, discharge start and discharge end are timestamped onto the docket.
-
Step 5
Invoice
Every load ends as a billable line with its minutes attached.
The driver drives. The system writes.
Status comes from where the lorry is, not from what the driver has time to tap. Out through the plant gate, in at the address — the position handles it.
The tablet runs locked to one screen: today’s loads, nothing else.
A text when the lorry leaves the plant
The customer gets a text the moment the lorry pulls out: the arrival time in minutes, worked out on driving time in live traffic, and a tracking link that stays live for 24 hours.
The site can see the lorry coming, so they stop ringing to ask.
What sits in the cab
- Standard Tablet An ordinary tablet, locked to the driver’s screen. No app to install.
- Option PTO unit A unit in the lorry reads the power take-off over the vehicle’s CAN bus and marks discharge to the second.
04The lorry
Built in a working lorry
Concra was written for our own ready-mix plant. The tablet in the first lorry is still in it, and the loads go out on it every day. We batch and deliver concrete ourselves.
