The Amex Blue Business Plus and Chase Ink Business Unlimited are the two most popular no-annual-fee business credit cards — and the default “which should I get?” question for small business owners, freelancers, and side hustlers. Both earn flat-rate rewards on all purchases, but their earning structures, sign-up bonuses, and ecosystems are fundamentally different. This is the complete head-to-head.
Quick verdict: The Amex Blue Business Plus earns more rewards per dollar — 2x points on the first $50K/year vs 1.5% unlimited. The Chase Ink Business Unlimited has a far better sign-up bonus ($750 vs ~$150-300) and fits into the Ultimate Rewards ecosystem for maximum travel value. For most small businesses, the sign-up bonus makes the Ink Unlimited the better first card, while the BBP is the better long-term earner.

Key insight: The BBP earns more at every spending level, but the gap depends entirely on how you value Membership Rewards points. At 1 cent per point (cash back), the BBP’s 2x is worth 2%, beating the Ink’s 1.5%. At 1.5-2 cents per point (airline transfers), the BBP’s effective rate is 3-4% — absolutely destroying the Ink’s 1.5%.

It takes 1.6-6 years for the BBP’s higher earning rate to overcome the Ink’s sign-up bonus advantage. The answer: get the Ink first for the bonus, then add the BBP for long-term earning.

The BBP’s flexible spending limit is a significant advantage for businesses with variable expenses. There’s no hard credit limit — Amex adjusts based on your spending patterns, payment history, and financial profile. This means a large unexpected purchase (equipment, inventory) is more likely to go through without hitting a ceiling.

The Bottom Line
The Amex Blue Business Plus is the better long-term earner — 2x points on $50K/year in spending, no foreign transaction fees, primary rental car insurance, and flexible spending limits make it the premium no-fee business card. The Chase Ink Business Unlimited is the better first business card — the $750 sign-up bonus, $10,000 purchase protection, and Chase ecosystem are hard to beat. The ideal path: start with the Ink Unlimited for the $750 bonus, add the BBP for ongoing spending, and pair with a Sapphire or Amex Gold card for maximum transfer partner value.
