The Capital One Spark Miles for Business credit card offers 2 miles per dollar spent on all purchases, plus 5 miles per dollar on hotels and rental cars booked through Capital One's travel booking site. There is no annual cap on the miles earned. The card has a $0 annual fee for the first year, then $95, which is still pretty reasonable considering its long-term benefits.

With this card, your miles can be redeemed for one cent each toward a travel purchase, or transferred to an airline or hotel partner. The miles won't expire for the life of the account, and as long as you pay your balance in full during that timeframe, you won't owe any interest. This card could be a great option for folks looking into business cards while wanting to maintain lower fees. And, you'd still have access to the Capital One Shopping portal, which is another great way to rack up points on everyday spending.
