TL;DR: Business credit cards with 0% intro APR—such as the Chase Ink Business Unlimited, Amex Blue Business Plus, and Capital One Spark Cash Plus—let companies finance purchases interest-free for 12–18 months. They are a tactical cash-flow tool when paired with a repayment plan, not a substitute for sustainable revenue.
The small-business credit card market has shifted decisively toward longer 0% intro APR windows as issuers compete for primary-card status among founders. According to industry tracking data, the average 0% intro period on top business cards has stretched from roughly 9 months to 12–15 months over the past three years, with several flagship products now offering 12–18 months on purchases and balance transfers. For cash-strapped operators, that window represents free working capital—if managed with discipline.

Where the Offers Stand
Cards like the Chase Ink Business Unlimited (0% for 12 months, flat 1.5% cash back), American Express Blue Business Plus (0% for 12 months, 2x points up to a cap), and Capital One Spark Cash Plus (0% for 12 months with a strong flat-rate structure) dominate the segment. Bank of America, U.S. Bank, and Wells Fargo round out the field with 0% windows of 9–15 months and varying rewards. The common thread: issuers trade short-term interest income for long-term swipe volume and deposit relationships.
Strategy: Treat the Window as a Loan
The winning play is to map every 0% purchase to a repayment date before the promo expires. Allocate the card to predictable, revenue-generating costs—inventory, software, seasonal hiring—rather than discretionary spend. Divide the balance by the remaining promo months and automate payments. The moment a balance would outlive the 0% window, stop charging and pivot to a card with a lower ongoing rate.
Case Studies
A 12-person e-commerce retailer used an 18-month 0% card to pre-fund a $60,000 holiday inventory buy, repaid in 15 equal installments, and avoided roughly $6,000 in interest versus a term loan. A boutique agency charged $25,000 in annual software and insurance premiums to a 12-month 0% card, earning $375 in cash back while preserving its credit line for payroll gaps. Both succeeded because the debt had a fixed payoff date.
FAQ
Q: Do 0% intro APR business cards hurt your credit?
A: Applying triggers a hard inquiry and temporarily lowers your score, but on-time payments and low utilization typically offset this within a few months.
Q: What happens when the intro period ends?
A: Any remaining balance accrues interest at the standard APR—often 18–29%—so plan to clear the balance before the deadline or transfer it.
Q: Can startups with limited history qualify?
A: Yes, many issuers accept sole proprietors and newer LLCs using personal credit and revenue projections, though limits may start modest.
