This is what I did when I had my business. I already have a Chase Sapphire personal card, and for the business I got the Chase Ink Business Cash. Every business expense went on the card, even most of my wholesale suppliers allowed me to pay invoices with the card and no additional fee. Points can transfer between Chase products so I transferred all the business card points to the Sapphire for the travel redemption benefits. Racked up a lot of points that way.
