The 4 Best Flat-Rate Rewards Business Credit Cards

There’s a lot to love about flat-rate rewards business credit cards. No matter what you’re spending on and when you’re spending, these cards will offer you consistent, dependable rewards across the board. Flat-rate rewards business credit cards can take a few different forms—maybe you’ll earn the same amount of cash back or a consistent rewards point multiplier, for instance. Whichever suits your business more.

And the best flat-rate rewards business credit cards don’t just give you access to consistent rewards, but they also provide unlimited earning potential.

That means you won’t have to worry about hitting a threshold for your highest rewards rates—there won’t be a spending cap on the best flat-rate rewards business credit cards. Meanwhile, most business credit cards with tiered rewards programs will only allow you to earn a top reward rate on up to a certain amount of spending each year.

We look at the best flat-rate rewards business credit cards for unlimited, even rewards for every dollar you choose to spend on your business.

Why You Might Need a Flat-Rate Rewards Business Credit Card

The best flat-rate rewards business credit cards can be a huge benefit to many companies—and if they’re right for you, you’ll love these cards. Here’s how to know if a flat-rate rewards business card is a good fit:

1. You spend on unconventional business expenses.

If you’re not spending primarily on traditional business costs, then you probably aren’t spending in the spending categories that tiered rewards programs reward the most. Unless you’re spending the most on office supplies, shipping expenses, travel, or other common small business costs, then a tiered rewards program will probably leave you earning a mere 1% cash back or 1x rewards for most of your spending.

If you’re making a lot of non-conventional business purchases, or your spending is highly variable across categories from month to month, then a flat-rate business credit card should be your primary business credit card. That way, all of the purchases you make the most—be them groceries or knitting supplies—will earn more than 1% or 1x, which will seriously add up.

2. Your other business credit card has a tiered rewards program.

Alternatively, you might have already found your perfect tiered rewards card that provides huge returns for your most frequent expenses, but you’re still getting just 1% or 1x for intermittent purchases. That’s where a flat-rate business credit card ought to come into play.

Getting a flat-rate business credit card for the purchases that only earn 1% or 1x on your tiered rewards card can seriously upgrade your spending. You might use a tiered rewards card for office supplies and see a 3% cash back return, but then use your flat-rate card for more obscure—but no less significant—purchases like holiday gifts for your employees.

Smart use of a flat-rate rewards business credit card in tandem with a tiered rewards program card means you’re earning as much as possible without juggling so many cards.

3. You’re tired of tracking your rewards.

Or, you also might just be tired of tracking your spending to make sure you’re getting the most rewards possible. Tiered rewards programs involve a lot of questions and contingencies. Each purchase you make with a tiered rewards card will come with uncertainties like spending caps, vendor classifications, and rotating top-earning categories. It’s enough to drive a small business owner mad.

So, you might move over to a flat-rate rewards business credit card for no reason more than peace-of-mind. You’ll be able to spend—and allow your employees to spend—knowing that you’re earning as much as possible, no matter which expenses end up on your account.

Another top flat-rate rewards business card that also offers cash back rewards is the Capital One Spark Cash for Business. This card will give you an unlimited 2% cash back for every dollar you spend with it.

Plum Card from American Express: Best Flat-Rate Rewards with Flexible Payment

Though the Plum Card is yet another flat-rate business rewards card that offers up cash back for your spending, its cardholder experience is certainly a unique one—the Plum Card actually offers up some of the most flexible terms on the market.

It gets its flat-rate title from the unlimited 1.5% cash back it rewards you for any payments you’re able to make early within 10 days of your statement positing. But as a charge card, the Plum Card doesn’t quite qualify as a flat-rate business credit card. You won’t have a set limit on your credit with this flat-rate business credit card, so you’ll be able to spend without worrying about maxing out your available credit.

The Plum also offers an unparalleled grace period of 60 days, which will allow you to take your time with paying down your balance without incurring late fees. And from month-to-month, you’ll be able to choose what kind of Plum cardholder you want to be—the early bird who gets the 1.5% cash back or the late-comer who avoids late payment fees.

Keep in mind though, this kind of flexibility comes at a cost. Though American Express will waive your first annual fee with the Plum Card, you’ll have to pay the relatively high $250 fee each year thereafter.
