8 surprising business expenses you can put on a credit card (and when it makes sense)

# Why this matters

Small and mid-size business owners often leave rewards on the table by assuming vendors won't accept credit cards. When vendors accept cards without a fee, routine business spending can generate substantial points and miles over time. But fees matter: a percentage surcharge quickly offsets rewards value, so confirm the vendor's exact payment policy before swiping.

# Common expense categories where a card can work

• Construction materials and hardware: Cards with merchant-category bonuses may pay off here. One card update in 2025 added 2 points per dollar on U.S. construction material and hardware suppliers on purchases up to a high combined limit, making local parts suppliers and plumbing materials candidates for card payments.

• Insurance premiums: Major insurers sometimes accept card payments and may offer discounts for paying in full on a card. This has been observed with larger insurers rather than necessarily with smaller providers.

• Restaurant equipment and smallwares: Equipment suppliers can vary. One vendor charged fees for large purchases but allowed smaller everyday items on a card with no fee. Shopping multiple vendors and asking payment-policy questions can uncover better terms.

• Employee bill advances: Instead of giving an employee cash or a check, businesses can pay an employee's vendor directly for large, unexpected expenses (for example, dental work). That both reduces fraud risk and can earn rewards if the vendor accepts a business card.

• Lawyers and retainers: Some law firms accept credit cards for retainers. While many firms traditionally did not take cards, a few larger firms have accepted card payments without charging a fee.

• Other vendor supplies (example: beverage cartridges): Smaller recurring vendor purchases sometimes accept card payments without a fee. In one example, a beverage supplier accepted card payments on flavor cartridges with no fee, transforming previously unpaid card-eligible spend into rewards-earning transactions.

# How to evaluate whether to pay with a card

1. 1Confirm fees in writing. Ask whether the charge is a fixed fee or a percentage and whether the vendor absorbs any portion.
2. 2Do the math. Compare the fee to the rewards value you'd earn. A 3% surcharge commonly outweighs typical rewards rates.
3. 3Check card category bonuses and limits. Some cards offer elevated earnings for specific merchant categories and include annual spending caps that affect value.
4. 4Consider non-financial benefits. Paying a vendor directly for an employee advance reduces cash handling and fraud risk, which has operational value beyond points.

# Practical steps

• Make asking about card acceptance a standard vendor checklist item during onboarding.
• Track where you get charged fees and renegotiate or switch vendors if fees are excessive.
• Route large purchases through cards only after confirming no surcharge or after factoring the surcharge into total cost comparisons.
