You have to read the fine print to see that those percentages are limited. Your business only earns 5% cash back for the first $2000 of office supply purchases each year. For gas station purchases the same applies. For your first $2000 in annual gas station purchases, you earn 2% cash back. Afterwards purchases at gas stations or office supply stores earn the same rebate as other purchases. For your first $5000 in other annual purchases your business earns 0.25% cash back. Other purchases in excess of $5000 earn 1% cash back. That $5000 includes your gas and office supply purchases.

Your business can also earn 0.25% cash back at select warehouse clubs and discount stores. That extra savings could be enough to give you the edge over your competition. Many cash back credit cards exclude these discount warehouse purchases.

To help savings add up even quicker, this credit card offers a 0% introductory APR on purchases for 12 months and there is no annual fee. Balance transfers have a 5.99% APR for 12 months.

Despite the cash back limitations, the Discover Business Card could be a perfect match for your business. Analyze where your business uses its credit card the most. Then estimate how much you could save. If your business spends money at gas stations or office supply stores, a cash back or rewards credit card of some type is a must. If you spend significantly more at gas stations consider a business gas credit card.

Overall this credit card is best suited for businesses with smaller budgets. A larger business would quickly reach $2000 in gas or office supplies. If that is the case, your buying power should be able to get you a better deal. Or your business could use a different credit card once your office supply and gas station limits are reached.
