The verdict
On a typical year of business spending, the American Express® Business Platinum earns about $642 a year in rewards and the Capital One QuicksilverOne about $675, valuing every point at a flat 1 cent. The American Express® Business Platinum charges $895, but carries about $1,565 in annual statement credits that offset it for anyone who uses them. The Capital One QuicksilverOne charges $39, which you clear through its rewards and perks. Counting rewards, fees, and any credits, the Capital One QuicksilverOne delivers more total value, about $106 a year more for a typical spender, mostly because it earns more where you spend most, on everything else and advertising. Both earn transferable points rather than flat cash, so the deciding factor is whose transfer partners reach the airlines and hotels you would actually book. On the sign-up bonus, the American Express® Business Platinum currently has the larger welcome offer. A welcome bonus is a one-time event, so weigh it apart from the ongoing rewards.
Pick the American Express® Business Platinum if your spending leans toward travel. Pick the Capital One QuicksilverOne if your spending leans toward advertising, shipping, office supplies.
