Chase Ink Bold Ultimate Rewards Business Card offers 50,000 points ($500) Sign-Up Bonus after $5,000 in purchases. The card offers flexible spending limits and requires you to pay off your balance in full each month. The annual fee of $95 is waived for the first year. I sell items on eBay and Craigslist so I applied for a business card under sole proprietorship with my name as business ID and Social Security number as tax ID.
