That depends on what you plan to use your small business credit card for the first place.In general, credit cards like many of the American Express offers above provide rewards points in one of two ways:A low but consistent cashback rewards points accrual rate, such as 1% or 2%, on all purchases with the cardA high but specialized cashback rewards points accrual rate, such as 4% to 6%, for purchases within select categories of products or within certain time framesThe higher rewards accrual rate is obviously more advantageous if you plan to use your credit card for specific purchases. Say that you want to only use your credit card to buy a lot of office supplies for your business. In that case, a more specialized credit card with a high cash-back rewards rate will be a better pick.But if your business expenses are more variable and you don't spend a ton of money at a single place or on specific products, the more consistent cashback reward program is probably a better choice.Take a look at your finances before applying for a credit card to see how and where you spend your money for your business. This can help you determine whether a given credit card's rewards scheme is a good fit for your business's needs.
