For transport companies · Diesel slips
Walvis Bay to Windhoek, the Trans-Kalahari to Gobabis and Buitepos, the Trans-Caprivi to Katima Mulilo: every fill on the road is a slip someone in your office types and checks. Your drivers WhatsApp a photo of each slip, and by 7 the next morning your fuel sheet is checked, one tab per truck, with anything that doesn't add up in red.
Why it matters now
50ppm diesel went from N$19.63 a litre in February to N$27.86 in October.
Date, plate, station, odometer, litres and amount, typed by hand, slip after slip.
A plate typed one digit wrong books a fill to the wrong truck, and the km per litre of both stops making sense.
A fill checked weeks later is a question the driver can no longer answer.

How it works
After every fill, one photo of the slip on WhatsApp. That is all the driver does.
Truck, date, station, litres, price and odometer, checked against the tank size, the last fill and the truck's usual km per litre. A person checks every row against its photo.
One tab per truck, in Excel, with anything that doesn't add up in red and the reason beside it.
What it looks like
| Slip | Vehicle | Litres | Km/l | Check |
|---|---|---|---|---|
| S01 | N 12345 W | 210.40 | 3.1 | ok |
| S02 | N 12346 W | 341.00 | 2.9 | 341 L into a 300 L tank |
| S03 | N 12354 W | 180.20 | - | plate not on your fleet list; N 12345 W is one character off |
Sample rows from made-up slips. Real rows also carry the date, station, odometer, price, amount and the photo.
Questions
Yes. We work by WhatsApp and email from Johannesburg, so the town your trucks are based in makes no difference.
No. A slip from Buitepos or from Gaborone is read the same way, in N$ or Pula, and lands on the same truck's tab.
Monthly in advance, through your bank's cross-border payment to our South African account. The Namibia dollar and the rand are at par, so the amount does not move.
No. They send a photo on WhatsApp, which they already have.
More litres than the tank holds, the same slip sent twice, two fills for one truck on the same day, more diesel per km than the truck's usual, and a price above the station's usual.
No. We take the typing away, not the person. The time goes into the red rows.
On our own computer in South Africa, under a one-page data agreement signed before your first slip. Stop, and we delete our copies within 30 days.
