Heads up, awardtrail readers! Chase is boosting the signup bonuses on their no-annual-fee Ink Business Cash and Ink Business Unlimited cards. You can now snag a sweet $900 cash back (that's 90,000 Chase Ultimate Rewards points if you prefer to think in points!) after spending $6,000 in the first three months. This matches the highest bonus we've ever seen on these cards, making it a prime opportunity for small business owners (or anyone who qualifies for a business card) to stock up on rewards. But here's the catch: word on the street is that this increased bonus is ending soon, although we don't have an exact date yet. So, if you've been eyeing one of these cards, now's the time to jump on it. Plus, don't forget you can often find these offers through referral links, letting you help a friend score a bonus, too (plus you get one!). Also, Rakuten is offering an additional bonus for the Ink Unlimited card, so check them out too. These cards also come with a 0% introductory APR for 12 months, which could be helpful for managing cash flow. Remember, starting October 7, 2025, Chase business card referrals only pay out if your friend is a *new* Chase business card customer, so keep that in mind when referring.
