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.
