A business card without a business bank account is still mixing your finances. The right sequence: bank account → business card → credit profile. See the banking hub →

How to choose the right card

If you're just starting out: Capital One Spark Cash Plus. Simpler approval process, flat rewards, no category tracking. Get the card, separate your spending, and build payment history.

If you spend $500–$3,000/month on software and tools: Chase Ink Business Cash. The 5% on internet and office categories is essentially free money on subscriptions you're already paying. No annual fee means every dollar of rewards is pure return.

If you're spending $5,000+/month across your business: Amex Business Gold. The 4× on your top two categories scales with your spending. At $5K/month the math more than covers the $375 annual fee. Best combined with a no-fee card for spending outside the bonus categories.

Card strategy for solo operators

Most established operators run two cards: a category-bonus card (Chase Ink or Amex Gold) for primary business spend, and a flat-rate card (Capital One Spark) for everything else. The combination maximizes rewards without complexity.

Cards and business credit

Business credit cards that report to business credit bureaus (Dun & Bradstreet, Experian Business, Equifax Business) help build your Paydex score and business credit profile — which is what lenders look at when you eventually need a business line of credit or loan.

Capital One and American Express both report business card activity to business credit bureaus. Chase Ink's reporting varies. Regardless of which card you choose, pay in full every month — business credit scoring heavily weights on-time payment history.
