How do diesel fuel cards work?

Fuel cards are like credit cards for your transport expenses.

They work by letting you buy your diesel, oil, or toll charges now and then pay for it later.

You can select one that gives you a weekly receipt or choose an option that provides your business with a monthly invoice — whatever is most convenient for your company.

What this means is that fuel cards are perfect for cash flow management. This is because it gives you the breathing space to settle other bills that must be paid upfront, safe in the knowledge that you can pay your fuel costs at a later date.

So, fuel cards don’t just work as a credit card for travel expenses. They work as a way of keeping your business on the road.
