While you might be looking to lower your business credit card expenses right now, it’s also a vital time to keep track of every dollar your business spends. Having the right credit card to separate your business expenses from personal expenses can make your life significantly easier.

Not only that, but business credit cards can also offer higher spending and credit limits, which might be a necessity to make those large business purchases. Some cards even have introductory interest rates on purchases and balance transfers, making them a helpful tool in the current economic climate.

Our comprehensive credit card methodology compares every aspect of each business credit card to our “benchmark credit card” — the Citi® Double Cash Card — to determine which cards can potentially bring you maximum value. And while the Double Cash is a personal credit card, a comparable business credit card is the American Express Blue Business Cash™ Card, as both cards earn flat-rate cash back at the same market-leading rate.

So take a few minutes to take a look at our list of the best business credit cards in 2021 and see if one might be useful to your business right now.

Blue Business Plus from American Express: Best overall business card

Why it’s great in one sentence: For businesses looking to pay off large purchases with no interest for an extended time, the Blue Business Plus from American Express offers an introductory 0% APR on purchases for the first 12 months you have the card, 13.24%-19.24% variable afterward (see rates and fees).

This card is right for: Small businesses with less than $50,000 in annual expenses who want to earn travel rewards for no annual fee, but who can also utilize an introductory interest rate.

Highlights:

  • Earn 2 points for every dollar you spend on all purchases up to $50,000 per year, then 1 point per dollar thereafter.
  • Points can be redeemed for travel through Amex Travel at a rate of up to 1 cent per point.
  • Points can also be transferred to any of Amex’s 21 airline and hotel partners.
  • 0% introductory APR on all purchases for the first 12 months (13.24%-19.24% variable afterward, see rates and fees).
  • No annual fee (see rates and fees).
  • Terms apply.

Welcome bonus: Earn 15,000 bonus points after you spend $3,000 in eligible purchases within your first three months after opening the account.

What we like about the Blue Business Plus: If your business needs to make ends meet right now, the Blue Business Plus offers a 0% introductory APR on purchases for the first 12 months you have the card. Just be careful to pay off your debt in that time, because the rate jumps to a variable 13.24%-19.24% after the 12 months are up.

The Blue Business Plus also earns 2 points for every dollar your business spends on all purchases up to $50,000 each calendar year. After that, the rate drops to just 1 point per dollar, so this is a card that caters more toward small businesses who don’t have extraordinary yearly expenses.

The Membership Rewards points earned with this card are both flexible and valuable, assuming you want to bank them for travel in the future. You can redeem them directly for flights or hotel stays at a rate of up to 1 cent per point via Amex Travel, or transfer them to any of American Express’s 21 airline and hotel partners for potentially even more value.

One thing that could be better: Although one of the perks of the Blue Business Plus is that you can earn points toward free travel, you may not have travel on your mind right now. And while you can convert the points earned on this card to cash, it’s a pretty poor value with each point worth only 0.6 cents apiece.

But if you’d prefer to earn cash back instead of travel rewards, you’ll want to look at the American Express Blue Business Cash Card instead. The card’s features are virtually the same as the Blue Business Plus, but you’ll earn cash back instead of points, which could be a better fit if you want to use your credit card rewards now rather than save them for later.

Where it beats our benchmark card: Extensive airline and hotel transfer partners, some travel and purchase protections, introductory rate on purchases.

Where our benchmark card is better: The Citi Double Cash has an introductory interest rate on balance transfers.

Ink Business Unlimited Credit Card: Best no-annual-fee card

Why it’s great in one sentence: With 1.5% cash back on every purchase your business makes and an impressive $750 bonus cash back offer for new card applicants, the no-annual-fee Ink Business Unlimited Credit Card is a great choice for business owners who don’t want to tie up a lot of time with their credit card rewards.

This card is right for: Businesses who want the simplicity of flat-rate cash back rewards on their regular business expenses from a credit card with no annual fee.

Highlights:

  • Earn 1.5% cash back on all your purchases.
  • 0% introductory APR on purchases for the first 12 months after opening the account (13.24%-19.24% variable APR afterward)
  • Purchase protection against damage or theft.
  • Primary car rental insurance when renting for business trips.
  • Expert business users can convert the cash back to flexible travel points when pairing the Ink Business Unlimited with the Ink Business Preferred Credit Card, or a personal Sapphire card.
  • No annual fee.

Welcome bonus: Earn $750 in bonus cash back after you spend $7,500 on purchases in the first three months after you open the card.

What we like about the Ink Business Unlimited: Even in the best of times, business owners have a lot on their plates, and don’t necessarily want to spend a lot of bandwidth thinking about their credit card. If that sounds like you, the Ink Business Unlimited could be a perfect fit.

There are no bonus categories to chase with the Ink Business Unlimited — you’ll just earn a flat 1.5% cash back on every purchase your business makes, meaning you can put this card in your wallet and use it anytime you’re buying items for your business. The cash back can be redeemed at any time as a statement credit or a deposit into most US checking and savings accounts.

Now’s also the perfect time to apply for this card, because it’s featuring the highest sign-up bonus we’ve ever seen offered for it. New Ink Business Unlimited card applicants can earn $750 in bonus cash back after spending $7,500 in the first three months after opening the account.

And if you decide down the line that you’d prefer travel rewards to cash back, you can pair the Ink Business Unlimited with the premium Ink Business Preferred (or alternately, the personal Chase Sapphire Preferred Card or Chase Sapphire Reserve) and convert your cash back to travel points, then redeem the points for travel or transfer them to any of Chase’s 14 airline and hotel loyalty partners.

One thing that could be better: You won’t want to use the Ink Business Unlimited overseas, as it carries a 3% foreign transaction fee, which would obliterate any rewards you’d earn on international purchases. Also, you won’t find any travel protections on this card, with the exception of primary car rental insurance when you’re renting for business purposes.

And if your business has less than $50,000 in annual expenses, you could be better off with the American Express Blue Business Cash Card, which earns 2% cash back on up to $50,000 in purchases each year (then 1% thereafter). However, if you want the option to use your rewards for more valuable travel redemptions down the road, the Ink Business Unlimited is still a better choice, since you can pair it with a premium Chase Ultimate Rewards card at any time to open up a slew of travel options.

Where it beats our benchmark card: Sign-up bonus, purchase protections, primary car rental insurance when renting for business trips, an introductory rate on purchases.

Where our benchmark card is better: The Citi Double Cash earns a slightly higher rate of cash back on all purchases and has an introductory rate on balance transfers.

Ink Business Preferred: Best sign-up bonus

Why it’s great in one sentence: The incredibly high 100,000-point welcome bonus on the Ink Business Preferred is one of the best you’ll find on a business card, especially for one that offers solid bonus categories and benefits — all for a low annual fee.

This card is right for: Businesses looking to earn flexible points toward travel, while also having access to unique benefits such as cell phone protection.

Highlights:

  • Earn 3 points for every dollar you spend on travel, shipping purchases, internet, cable, phone services and advertising purchases made with social media sites and search engines (up to $150,000 in combined purchases each card anniversary year, then 1x).
  • Earn 1 point per dollar on all other purchases.
  • Points can be redeemed with a 25% bonus when booking airfare, hotels, car rentals and cruises through the Chase Ultimate Rewards travel portal.
  • Points can also be transferred to any of Chase’s 14 airline and hotel partners at a 1-to-1 ratio.
  • Cell phone protection against damage or theft when you pay your cell phone bill with your card.
  • Purchase protection against damage or theft.
  • Primary car rental insurance when renting for business trips.
  • Trip delay protection and trip interruption/cancellation insurance.
  • No foreign transaction fees.
  • $95 annual fee.

Welcome bonus: Earn 100,000 bonus points after you spend $15,000 on purchases in the first three months after you open the card.

What we like about the Ink Business Preferred: By far, one of the best features of the Ink Business Preferred is its incredibly strong sign-up bonus — currently at 100,000 points, although it does require a large spending commitment of $15,000 in the first three months after you open the card. However, many businesses have routine monthly expenses that can easily meet that threshold.

Chase’s Ultimate Rewards is one of the best loyalty points programs in the travel world. You can redeem your points through Chase’s travel portal and receive a 25% bonus, or you can transfer your points to 14 different partner airlines and hotels, such as Hyatt, United and British Airways.

The Ink Business Preferred also offers cell phone protection as a perk, covering both your own cell phone and everyone else listed on your monthly bill as long as you pay the entire bill with the card each month. This means your employees (or potentially even family members) can be covered for no extra cost. You can submit up to three claims every 12 months and be reimbursed up to $600 per incident, with a $100 deductible per claim.

One thing that could be better: Although the bonus categories on the Ink Business Preferred are quite generous, you won’t earn any bonus points on some popular everyday business purchases, such as gas, restaurants or at office supply stores. The 3x categories are also capped at a combined $150,000 in total purchases each year -— after that, you’re only earning 1 point per dollar spent.

Where it beats our benchmark card: Sign-up bonus, cell phone protection, purchase protections, travel protections, primary car rental insurance, no foreign transaction fees.

Where our benchmark card is better: The Citi Double Cash has no annual fee and an introductory rate on balance transfers.

American Express Business Gold: Best for flexible bonus categories

Why it’s great in one sentence: The Amex Business Gold card gives businesses the flexibility to automatically earn bonus points on the two categories they spend the most money in during each billing period.

This card is right for: Businesses who spend money in varying categories over the course of the year and who want to be rewarded with extra travel rewards on their largest purchases each month.

Highlights:

  • Earn 4 points for every dollar you spend on two select categories you spend the most in each billing cycle (up to $150,000 in combined purchases per year, then 1x).
  • Earn 1 point per dollar on all other purchases.
  • Flexibility to redeem points through American Express Travel and receive 25% of your points back.
  • Points can also be transferred to any of Amex’s 21 airline and hotel partners.
  • Trip delay protection.
  • Extended warranty and purchase protection.
  • No foreign transaction fees (see rates and fees).
  • $295 annual fee (see rates and fees).
  • Terms apply.

Welcome bonus: Earn 70,000 bonus points after you spend $10,000 on eligible purchases within the first three months of card membership.

What we like about the Amex Business Gold: The Amex Business Gold shines when it comes to earning as many points as possible on your business expenses, even if they aren’t in the same categories every month.

You’ll earn 4 points per dollar on the top two categories where your business spent the most in each billing cycle, from a list of six possible categories:

  • U.S. purchases for advertising in select media (online, TV, radio).
  • U.S. purchases made directly from select technology providers of computer hardware, software and cloud solutions.
  • U.S. purchases at gas stations.
  • U.S. purchases at restaurants.
  • U.S. purchases for shipping.
  • Airfare purchased directly from airlines.

The best part of this system is that American Express will automatically calculate your top two categories at the end of each billing cycle — you don’t have to speculatively select your categories in advance. This is great in the current economic environment, as you aren’t locked into two categories for the entire year, and your bonus points can change as your purchases change.

You’ll also currently find an impressive welcome bonus on the Amex Business Gold: 70,000 bonus points after you spend $10,000 on the card in the first three months after opening the account. That’s the highest publicly available bonus we’ve ever seen on this card.

One thing that could be better: For a card with such a high annual fee, there aren’t too many travel benefits on the Amex Business Gold. You won’t receive any luxury travel perks or even any travel statement credits. This means aside from the bonus credits in the first year, there aren’t many opportunities to offset the annual fee, so you’ll need to make sure the earning rate is worth it for your overall spend.

Also, it’s important to note that your 4x bonus point categories are capped at $150,000 in spending across the combined six categories each calendar year. Once you hit that threshold, the card only earns 1 point per dollar on everything you buy.

Where it beats our benchmark card: Welcome bonus, transferable points, trip delay protection, purchase protection, no foreign transaction fees.

Where our benchmark card is better: The Citi Double Cash has no annual fee and an introductory rate on balance transfers.

Business Platinum Card from American Express: Best for travel perks

Why it’s great in one sentence: Although it’s the most expensive card on our list, when travel returns to normal, the Business Platinum Card from American Express offers luxury travel perks such as airport lounge access, elite status and much more.

This card is right for: Business travelers who want a card that provides top-notch luxury perks, transferable travel rewards and travel protections.

Highlights:

  • Earn 5 points for every dollar you spend on flights and prepaid hotels booked on Amex Travel.
  • Earn 1 point per dollar on all other purchases.
  • Points can be redeemed for travel through Amex Travel at a rate of up to 1 cent per point, and you’ll earn 35% of your points back on airfare with one selected airline, up to 500,000 bonus points per calendar year.
  • Points can also be transferred to any of Amex’s 21 airline and hotel partners.
  • Up to $200 in annual statement credits on eligible U.S. purchases at Dell.com.

  • Complimentary Gold Elite status with Hilton and Marriott hotel chains.
  • Complimentary Preferred Elite status with Hertz, Avis and National Car Rental chains.
  • Access to American Express Fine Hotels & Resorts.
  • Travel cancellation and trip delay protection.
  • Extended warranty and purchase protection.
  • No foreign transaction fees (see rates and fees).
  • $595 annual fee (see rates and fees).
  • Terms apply.

Welcome bonus: Earn 100,000 bonus points after you spend $15,000 on qualifying purchases within the first three months of card membership.

What we like about the Amex Business Platinum: This is a card for the true road warrior who considers travel perks a necessity. Although many of the Amex Business Platinum card’s benefits are sitting on the sideline right now, they’ll be more valuable than ever once travel is back to normal.

The card’s lounge access is by far one of the best benefits, allowing you to relax in comfort at over 1,200 lounges worldwide, including Amex’s own Centurion Lounges. On the hotel front, you’ll also receive elite Gold status in both the Marriott and Hilton program, which can get you complimentary upgrades and breakfast at participating hotels.

To partially offset the card’s annual fee, you also earn up to $200 in annual airline incidental credits, up to $200 toward eligible US purchases at Dell.com each year, and up to $100 for reimbursement of a Global Entry or TSA PreCheck application fee. In the first year alone, these credits are worth up to $500.
