Get the Business Advantage Unlimited Cash Rewards Mastercard® Credit Card if your business keeps a combined $50,000 or more at Bank of America and Merrill. Enrolling in the bank’s Preferred Rewards for Business program lifts the card’s 1.5% cash back to at least 2.25% on every purchase. With less banked there, a no-fee card paying a flat 2% earns more.
