Key takeaways

  • If you are a small-business owner, then the Capital One Spark Cash Plus and The Plum Card® from American Express are two business cards to consider that allow flexibility when it comes to spending limits.
  • While the Spark Cash Plus offers cash back rewards, the Plum Card features a discount on your balance (if paid within a certain period).
  • The right card for your business will come down to your preferred rewards strategy and the additional card benefits you want.

The Capital One Spark Cash Plus and The Plum Card® from American Express are both business cards that can bring value to small businesses in a variety of ways.

The Spark Cash Plus not only features an unlimited, flat cash back rate, but it also offers a generous introductory bonus as well as an opportunity to receive an annual bonus when you meet the spending threshold. On the other hand, the Amex Plum Card has a lower welcome offer value but a unique “rewards” structure in which you won’t earn traditional cash back. Instead, you can receive a discount on your balance (if paid within a set period of time). Unfortunately, both cards come with relatively high annual fees, but business owners can add additional employee cards for free.

Capital One Spark Cash Plus vs. The Plum Card from American Express highlights

Which card earns the most?

Only the Spark Cash Plus officially earns rewards, so it’s the winner when it comes to rewards earning. Certainly, the Plum Card encourages responsible card management by offering a discount when you pay for your purchases early, but there are not rewards in the traditional sense.

Capital One Spark Cash Plus spending example

With the Spark Cash Plus, you’ll earn 2 percent cash back on all eligible purchases (and 5 percent cash back on Capital One Travel hotel and rental car purchases). In addition, you’ll have the opportunity to earn:

  • A $2,000 welcome bonus when you spend $30,000 in the first three months
  • An additional $2,000 bonus for every $500,000 spent in the first year
  • A $150 annual fee refund every year you spend at least $150,000

With the Plum Card from American Express, you won’t necessarily “earn” any money, but it’ll help you save money. The unlimited 1.5 percent monthly discount you’ll receive on eligible charges you pay off within 10 days of your statement due date could be considered automatically redeemed cash back, but that’s still not as high a rate as what’s offered by the Spark Cash Plus.

The bottom line

Overall, both the Capital One Spark Cash Plus and Plum Card from American Express are good options for higher-spending businesses that can afford to pay a significant annual fee.

For the Capital One Spark Cash Plus, the spending requirements to earn its welcome bonus and annual bonus are steep — meaning businesses on a tighter budget may not be able to fully maximize the card’s value. However, for businesses with no problem reaching these spending requirements or offsetting an annual fee, this business credit card can easily be a valuable addition to your wallet.

If you’re interested in an American Express business card and would prefer a percentage discount on your balance rather than traditional rewards, the Plum card might be right for you.
