Best credit card for small business in Australia (2026 Guide)

Running a small business usually involves managing lots of regular expenses and trying to keep on top of cash flow during the month to support daily operations and drive growth. For many Australian businesses, a credit card can make these tasks easier, covering immediate costs and keeping spending organised, while offering some benefits on top.

However, with so many options on the market, choosing the best credit for a small business requires quite a bit of research, with comparisons of interest rates and rewards, and decisions about whether it’ll actually fit how you operate.

To help you, this blog will break down how small business credit cards work in Australia, why you might need them, the features to look for, and 5 of the best cards available in 2026. There’s also an introduction to Wise Business — a debit card alternative that might make more sense, especially if you operate across borders.

Why might small businesses need credit cards?

A small business credit card separates business spending from personal finances while providing short-term credit and a few additional benefits like rewards, insurance, employee controls, and expense management tools. These cards reduce the immediate financial burden of work-related expenses, allowing businesses to settle balances at a later date.

For micro businesses and SMEs in Australia, business credit cards can be used to:

• Cover cash flow gaps between income and expenses
• Pay for recurring costs like software subscriptions or utility bills
• Bring together all employee spending within one account
• Earn reward points or cashback on regular business purchases

For example, a marketing agency might use a low-interest rate credit card to fund an advertising campaign and some SaaS tools, then pay off the balance when all the client invoices are settled. It can provide much-need financial breathing room when used correctly, and unlock useful perks.

When credit cards might not make sense

Credit cards typically work best when balances are cleared regularly. However, interest rates on business credit cards in Australia can be higher than alternative forms of finance, so they are likely to be expensive for long-term borrowing.

That’s why businesses often pair a credit card with other tools like debit cards or multi-currency accounts to manage costs. Any credit facilities should make running and funding a business easier, not add stress or become a debt trap.

Key features to look for in a small business credit card

When trying to shortlist the best corporate credit card for small business, it’s useful to run through a checklist of common features. Not all of these are ‘essential’ — it will depend on what your business needs from a credit card.

• Annual fees - most cards have an annual fee. A higher fee might be worthwhile if it’s balanced out by a range of useful rewards and perks.
• Interest-free period - commonly up to 55 days when balances are paid in full.
• Rewards programs - some cards are tied to reward programs that allow you to earn points, cashback, or airline miles on eligible spending.
• Cash advances - allow you to withdraw cash using your credit card, but typically with high interest rates and fees.
• Employee cards - the ability to issue more cards with spending limits is very useful for centralising and tracking employee expenses.
• Insurance benefits - some cards offer complimentary business or travel insurance.
• Foreign transaction fees - many cards charge foreign transaction fees of 3% or more. Make sure to check the rate beforehand if you need to transact bank internationally.

Now, let’s look at each of these in more detail, starting with one of NAB’s best rewards credit card for small business.

NAB Rewards Business Signature Card

As the name suggests, NAB’s Signature credit card¹ is big on earning rewards. You can rack up 3.75x points for every $1 you spend², and there isn’t a monthly cap on how you can earn, making it potentially lucrative for businesses completing lots of regular payments.

Other key features include:

• Complimentary business-related transaction and accident insurances
• Additional employee cards for up to 1,000 cardholders per facility ($175 annual card fee applies to each additional card)³
• Redeem points for travel with Webjet or as gift cards from select retailers

You can get NAB’s business card for a $175 annual fee, but there are several eligibility requirements: a 12+ month ABN registration, GST registration, and $75,000+ annual turnover. The purchase interest rate is 18.50% per annum, and you can get up to 44-days interest free on ‘everyday’ business expenses.

ANZ Business Black card

The ANZ Business Black Card⁴ is targeted towards businesses with owners or teams that travel regularly. You can get a more modest 1.5x reward points for every $1 spent, but only for the first $10,000 during each statement period, dipping to 1x thereafter. There’s no cap, though.

Other key features include:

• Complimentary domestic and international travel insurance
• ANZ Global Business Concierge service offering travel booking assistance, plus priority dining reservations and discounted tickets for trade and sporting events

ANZ’s card is a bit more expensive at $300 per year, and you’ll have to pay $75 per year per card to enrol on the rewards program, so it might be expensive to get a bigger team earning points. The purchase interest rate is 20.24%, and you get 55 interest free days for certain purchases.

Any reward points can be redeemed as digital gift cards, ANZ cashback, or with airline partner programs like Velocity and KrisFlyer.

CommBank Business Low Rate Credit Card

CommBank’s⁵ low rate card is designed for smaller businesses that need to prioritise the cost of borrowing over points and perks. It has a simpler structure and no annual fees, but there isn’t a rewards points program, though you can earn cashback when activating offers through the CommBank app.

Key features include:

• Complimentary insurance for transit accidents and unauthorised transactions
• Low purchase interest rate (14.55% per annum)
• No fees for adding more cardholders

CommBank promises a ‘simple’ application process and there are no big hurdles to clear, but you will need an ABN number to register. The unsecured credit limit tops out at $50,000. This card might suit sole traders or startups that only carry an outstanding balance occasionally and want predictable, low costs.

St.George Business Vantage Visa Credit Card

Another compelling option for low costs and interest rates is the St.George Business Vantage Visa Credit Card⁶. There is a $55 annual fee, but the 9.99% purchase interest rate is one of the lowest on the market. There aren’t any rewards on spending, so you’ll have to look elsewhere if this is important for you and your team.

Key features include:

• Complimentary unauthorised transaction insurance
• Issue up to 99 additional cards with individual spending limits
• Up to 55 days interest-free on purchases when balances are paid in full

St.George says “many business structures” are eligible to apply for the card. To get started, your business must be registered in Australia and have an ABN or ACN.

Westpac Business Choice Rewards Platinum Mastercard

Westpac’s Business Choice Rewards Platinum card⁷ is geared towards thriving smaller business that want to earn Qantas rewards on everyday spending, while keeping tabs on employee expenses. It sits firmly in the “mid-tier rewards” category, balancing points earning with practical business features rather than premium travel perks.

Key features include:

• Earn 0.75 Qantas points for every $1.50 spent on specific business purchases
• Complimentary international travel and flight insurances
• Add up to 99 cards with individual credit limits from $1,000

With Westpac, you’ll have to pay a $150 annual fee for each credit card, which might be expensive depending on the size of your business. The purchase interest rate is 20.24%, and you get 55-days interest free. You’ll need an ABN or ACN and other business details to register.

Pros and cons of small business credit cards

Finally, before taking out a credit card, weighing up the benefits and drawbacks can help you decide if it’s actually right for your business.

Pros of credit cards

• Short-term credit covers expenses and boosts cash flow while you wait for invoices to be paid.
• Reward programs and cashback make everyday purchases go further and help support the business.
• Business credit cards consolidate spending into one statement, which makes it easier to categorise expenses and reconcile accounts.
• Using a dedicated card separates your personal and business finances, and simplifies accounting and tax reporting.

Cons of credit cards

• There are annual fees on most credit cards, which are modest but might outweigh benefits if monthly spending is quite low.
• Interest can rack up quickly if you don’t clear balances before the interest-free period ends.
• Access to credit can encourage higher spending, especially if there aren’t any controls in place.
• Most cards charge 3% or more for foreign transactions.
• Encourages a reliance on credit and managing ongoing debt, which some small businesses might want to avoid.

Small business credit card FAQs

1. Does applying for a business credit card hurt my personal credit score?

Applying for a business credit card isn’t necessarily a negative ding on your personal credit score, but many Australian banks will run a hard credit check during the application process. The lasting impact on your personal credit score usually depends on your payment habits — late payments or defaults can have a big impact.

2. What is the minimum revenue required to get approved?

There isn’t a universal threshold you need to clear for revenue to get approval. The requirements will vary by bank and card type, so it’s important to research everything in detail before applying. Some issuers are happy to accept new startups, while others might look for a longer trading history, i.e. 1 year or more, and a higher turnover.

3. Can I use a business credit card for personal expenses?

It’s not recommended. Mixing your personal and business expenses can make bookkeeping and tax reporting much more complex, even if technically the issuer may allow you to complete personal transactions with a credit card.
