You probably haven't heard of Fleetcor Technologies (NYSE: FLT) stock and for good reason. It is in a boring space that doesn't get much press coverage. After all, it isn't involved with building spaceships to go to Mars, nor is it buying companies in the hope to dominate the world.

Instead, Fleetcor Technologies does what it is best at doing, which is managing fuel cards for corporate customers. And smart investors are buying this stock for good reason. In this post, I'll walk you through these reasons so you too can see the benefit of adding this stock to your portfolio.

Who is Fleetcor Technologies?

As I mentioned, Fleetcor Technologies manages fuel cards for corporate customers. What this means is that they offer credit cards for companies to give to employees when fuel is needed for a company vehicle.

The most popular example would be with transportation companies. A truck company would give its drivers access to a card that allows them to swipe it at a gas station and be on their way. No worrying about carrying money to pay for the fuel and no worrying about submitting an expense report for reimbursement.

And it isn't just truck companies that can benefit from this service either. When I worked for a rental car company in college, we used a credit card like this as well. I would simply drive to the gas station, swipe the card and be on my way. Instead of myself or my local branch dealing with fuel costs, we let corporate headquarters handle it all.

The bottom line is, partnering with Fleetcor Technologies makes a transportation companies life much simpler.

You might be wondering how exactly Fleetcor Technologies makes money. They do so in two ways.

So not only do they benefit from the processing fee, but they also benefit from the fuel sale too. And as gas prices rise, so too does the revenue Fleetcor earns.
