Advanta Credit Card has introduced a new business credit card which offers 90 days interest free on all purchases. The Advanta Platinum Business Credit Card charges no interest for 90 days on purchases, offers a business rewards program, and has no annual fee. The Advanta Platimum is perfect for a small business managing their cash flow. The 90 day interest free period is not a promotional offer and can provide up to $50,000 in working capital. While the business rewards program is not as competitive as other business rewards programs, it does provide redemption for travel, merchandise or cash. It is better than nothing. However, the main attraction for small businesses to get the Advanta Platinum card is to take advantage of the perpetual 90 day interest free period.
