Businesses Can Use Credit Cards for Unexpected Expenses

Businesses can strategically utilize credit cards for a range of unexpected expenses, transforming routine outlays into opportunities for earning valuable rewards and points. This approach, particularly beneficial for small to medium-sized enterprises, involves actively inquiring with vendors about credit card acceptance without incurring additional fees. A decade ago, the author discovered that Coca-Cola flavor cartridge purchases could be charged to a credit card without a fee, leading to a significant increase in previously untapped credit card spending across ten restaurants and a corresponding rise in earned points and miles. This experience prompted a consistent practice of asking vendors about fee-free credit card payment options, revealing opportunities in surprising sectors.

Careful financial consideration is paramount, as vendors may alter payment policies, and a typical 3% credit card surcharge can easily negate the value of earned rewards. However, when the numbers align favorably, foregoing credit card payments means forfeiting potential rewards. For instance, construction materials and hardware suppliers represent a significant category where credit card usage can be advantageous. The Business Platinum Card® from American Express, following its benefit refresh in 2025, offers 2 points per dollar on U.S. construction material and hardware suppliers, capped at $2 million in combined purchases annually, after which the rate drops to 1 point per dollar. This includes not only major retailers like Home Depot and Lowe's but also local parts suppliers for items such as plumbing repair services and faucets.

Utility bills present another substantial avenue for accumulating points and miles, though vigilance regarding fees is essential. Historically, utility companies often imposed a flat fee for credit card payments. However, recent trends indicate a shift in some cases, potentially moving towards different fee structures or even acceptance without surcharges, making them a viable option for reward accumulation. Similarly, advertising expenses, whether for digital campaigns or traditional media, can often be processed through credit cards. Many advertising platforms and agencies accept credit card payments, allowing businesses to earn rewards on their marketing budgets. This can include social media advertising, search engine marketing, and even print or broadcast advertising placements.

Other less obvious expenses that can be charged to a credit card include software subscriptions and online services. Many Software-as-a-Service (SaaS) providers and digital tool vendors accept credit cards for monthly or annual subscription fees. By using a business credit card with strong rewards programs, companies can earn points on these recurring costs. Furthermore, professional development and training expenses, such as online courses, conference registrations, and workshop fees, can often be paid with credit cards, providing another opportunity to maximize rewards. The key takeaway is to consistently evaluate vendor payment terms and proactively explore credit card payment options for a wide array of business expenditures, thereby optimizing financial strategies and enhancing reward accumulation.
