Cardlock Fuel Solutions for Fleets in Gauteng, North West & Mpumalanga
Secure fleet fuel cards, litre-level reporting and consolidated billing — total control over every drop of diesel your operation draws.
Fleet Fuelling Without the Cash, Chaos or Guesswork
A cardlock system gives each of your drivers a secure fuel card that works at designated DieselInBulk sites and partner locations across Gauteng, North West and Mpumalanga. No cash, no receipts stuffed in gloveboxes, no mystery spend — every transaction is logged against the driver, the vehicle, the litre and the price.
For fleet operators, fuel is usually the second-biggest cost after wages, and the least controlled. Cardlock closes that gap. You decide which fuel types each card may draw, set per-transaction and daily litre limits, and restrict usage to working hours if you choose. Your drivers refuel quickly and safely; your office sees everything.
Security & Control
Restrict fuel types, litre limits and time windows per card. Lost or stolen cards are deactivated instantly. PIN-protected transactions keep fuel in your tanks, not someone else's.
Transaction-Level Reporting
Every transaction records vehicle, driver, date, time, site, litres and price. Export CSV or PDF reports per vehicle, per driver, per depot — accounting and cost-per-kilometre analysis made simple.
Consolidated Billing
One monthly statement for your whole fleet with agreed credit terms for approved accounts. No more reconciling dozens of slips from different garages.
DieselInBulk Cardlock in Four Steps
Apply and configure
Contact our commercial team with your fleet size and monthly litres. We propose card controls, participating sites and billing terms that match how your operation actually runs.
Cards issued to drivers
Physical fleet cards (and digital tokens where available) are issued per driver or per vehicle, each with its own limits, PIN and fuel-type permissions.
Refuel at designated sites
Drivers refuel at DieselInBulk cardlock points and partner locations across our three provinces — many operating extended or 24/7 hours for long-haul routes.
Track, report, control
Transactions flow into your reports in near real-time. Set alerts for unusual activity, export data to your fleet or ERP system, and reconcile in minutes.
Reporting That Pays for Itself
Fuel fraud and shrinkage quietly drain fleet budgets — skimming, side-fuelling, inflated slips, after-hours fill-ups. Cardlock attacks every one of these. Validation rules flag transactions that break your patterns: litres above a vehicle's tank capacity, fills outside working hours, or activity far from an assigned route. Fleet managers tell us the reporting alone often recovers more than the cost of the programme.
