Looking for the best business credit cards? You're not alone. Millions of business owners want to carry the best cards, but don't know where to look or how to find them. Fortunately, there are a few pointers that can get you on the right track. When looking for the best credit cards for your business, keep a lookout for these three things that all great business credit cards have in common.

1. A Low APR

Don't ever sign up for a card with an interest rate of 20 percent or more, no matter how pretty the perks may be. A low interest rate can save you quite a pretty penny if you're in a pinch and you find that you can't pay your entire balance off in full one month.

Even if you never plan on carrying a balance, you need a credit card with a somewhat-decent APR. Emergencies come up and there's no way to predict the future. You may find yourself carrying a balance, even if it's only for a couple of months. That's why the best business credit cards have a low interest rate, regardless of what rewards are offered.

2. Business-Related Perks

Not all rewards cards are created equal, and the best business credit cards understand this. Sure, rewards that can be redeemed for video rentals and movie tickets are nice -- for personal credit cards.

Make sure your business credit card features rewards that benefit your business, not your personal life. Free office supplies or business travel may come in handy when you need it most.

3. Detailed Statements and Online Banking

The best business credit cards offer detailed line-item statements and online banking. Okay, technically these are two different things but they are related to one another. Not only will you be able to tell what types of purchases were made with your cards and where they were made, you'll be able to access the information online each and every day.

There's something to be said for having daily access to updated credit card activity -- especially if employees have access to your business credit cards. And online bill payment can make it easier to get those statements paid on time!

Remember, not all credit cards are created equal and business credit cards are no different. If you want to make sure you have the best business credit cards in your wallet, remember the above three tips.
