Key takeaways

• Your business credit score is a number that lenders, suppliers, and other creditors use to assess how reliably your business pays its bills and manages debt.
• In Australia, the main credit bureaus are Equifax, Experian, and illion (formerly Dun & Bradstreet), and each uses its own scoring scale, so the same business can have different scores across bureaus.
• Paying bills on time, keeping credit utilisation below 30%, and monitoring your credit report regularly are among the most effective ways to build a strong score.
• Keeping organised financial records and on top of your cash flow makes it easier to demonstrate creditworthiness when you need it most.

What is a business credit score?

A business credit score is a numerical rating that reflects how reliably your business meets its financial obligations. It's used by lenders, suppliers, landlords, and other parties to quickly assess the risk of doing business with you.

In Australia, business credit scores are calculated and held by credit reporting bureaus, including Equifax, Experian, and illion (formerly Dun & Bradstreet). Each bureau collects data from different sources and applies its own methodology, so your score can vary between them.

Your business credit score is separate from your personal credit score. Even if you're a sole trader, it's worth understanding how your business credit profile is built and what affects it.

Credit bureaus can record information about any business, but a company registered with the Australian Securities and Investments Commission (ASIC), including proprietary limited companies with at least 50 non-employee members, is treated as a "reportable entity" with more detailed credit obligations.

Why your business credit score matters

Your business credit score affects decisions that can directly shape your ability to grow. Understanding why it matters gives you a reason to stay on top of it.

Lenders look at your credit score when you're applying for a business loan or a line of credit. A strong score can mean access to better interest rates, higher borrowing limits, and faster approvals.

Suppliers also check business credit scores before agreeing to trade credit terms. If your score is low, a supplier may ask for payment upfront instead of offering you 30 or 60 day terms, which puts pressure on your cash flow.

Beyond borrowing, a healthy score signals good financial management to prospective partners and investors. It's a visible indicator that your business pays its bills and keeps its commitments.

How business credit scores are calculated

Business credit scores are calculated using a range of data points, and the exact formula varies by bureau. Knowing what goes into the score helps you focus on the factors you can influence.

The main factors that affect your score include:

• Payment history: whether you pay invoices, loans, and credit accounts on time
• Credit utilisation: how much of your available credit you're currently using
• Length of credit history: how long your business has had active credit accounts
• Type and number of credit accounts: the mix of credit products your business holds
• Public records: court judgements, defaults, insolvency proceedings, or tax debt disclosures
• Credit enquiries: the number of times your credit file has been accessed by lenders or creditors

The Australian Taxation Office (ATO) can also disclose business tax debts to credit bureaus if you owe more than $100,000 and haven't engaged with the ATO to resolve the debt. This can have a significant impact on your score.

Positive information, such as consistently paying on time, can also be reported and work in your favour. The more complete and consistent your payment history, the more reliable your score becomes over time.

How to check your business credit score

You can check your business credit score directly through Australia's credit bureaus: Equifax, Experian, and illion (formerly Dun & Bradstreet). Each bureau maintains its own credit file on your business, and it's worth checking all 3 to get a complete picture.

Most bureaus offer a free basic credit report, which shows your score and a summary of the data on your file. Paid subscriptions usually give you more detail, including payment history, any defaults, and credit enquiries.

When you check your own credit report, this is called a soft credit check and it doesn't affect your score. A hard credit check, by contrast, is recorded on your file and happens when a lender or creditor requests your report as part of an assessment, such as when you apply for finance. Too many hard enquiries in a short period can lower your score.

It's a good idea to review your credit report at least once a year, or before you apply for any significant finance. This gives you a chance to spot errors or outdated information and have them corrected before a lender sees them.

What is a good business credit score?

What counts as a "good" business credit score depends on which bureau generated the report, because each one uses a different scale. Understanding the ranges helps you interpret your score in context.

Equifax uses a scale of -200 to 1200. A score above 800 is generally considered excellent, while anything below 400 indicates higher risk. Experian and illion (formerly Dun & Bradstreet) both use a scale of 0 to 100, where a score above 80 is typically seen as low risk and anything below 40 may raise concerns for lenders and suppliers.

Keep in mind that lenders set their own thresholds, and a score that's acceptable to one lender may not meet the criteria for another. Your score is one of several factors assessed alongside revenue, time in business, and the nature of the credit you're seeking.

If you're unsure how your score compares, contact the relevant bureau directly. They can help you understand what your score means in the context of your industry and the type of credit you're looking for.

How business credit differs from personal credit

Business credit and personal credit are assessed separately, but for small business owners they can be closely linked. Knowing the difference helps you manage both more effectively.

Your personal credit score reflects your individual borrowing and repayment history, including credit cards, home loans, and personal loans. Your business credit score reflects the financial behaviour of your business as a distinct entity, including trade credit, business loans, and business credit cards.

For a sole trader or a small company without an established credit history, lenders may check your personal credit score as part of a business finance application. This is especially common early in a business's life when there isn't enough business credit data to make a lending decision.

As your business grows and builds its own credit profile, you can work to separate your business and personal credit. Keeping your business finances in a dedicated account, registering your business formally, and consistently trading under your business name are all steps that support this separation.

Good financial health across both your personal and business profiles strengthens your overall borrowing position. For more on how these fit together, see the Xero guide to solvency and what it means for your business.

How to improve your business credit score

Improving your business credit score takes consistent effort over time, but the steps are straightforward. Most of them come down to demonstrating that your business pays its bills reliably and manages its finances responsibly.

Pay bills on time

Payment history is one of the biggest factors in your business credit score. Paying invoices, loan repayments, and credit accounts on or before their due date shows creditors that your business is reliable.

If you're struggling to keep track of payment due dates, Xero's bill payment tools can help you stay organised and avoid missed payments. Setting up automatic reminders or payment schedules reduces the risk of late payments slipping through.

It's also worth reviewing your invoice payment terms with customers and suppliers regularly to make sure they're realistic and workable for your cash flow.

Monitor your credit report regularly

Checking your credit report regularly lets you catch errors, outdated entries, or fraudulent activity before they do lasting damage. Mistakes on credit files are more common than many business owners realise, and disputing an error can take time.

Request your report from each of the 3 major bureaus at least once a year: Equifax, Experian, and illion. If you find inaccurate information, contact the bureau directly to begin a dispute, and follow up to confirm the correction has been made.

Regular monitoring also gives you a clear baseline so you can track progress as you take steps to improve your score.

Maintain good cash flow management

Strong cash flow management supports your ability to meet financial obligations on time, which in turn protects your credit score. When you have clear visibility over money in and money out, you're less likely to be caught short when payments fall due.

According to Xero Small Business Insights, Australian small businesses waited an average of 6.6 days past the due date to receive payment in the December quarter of 2025, the second lowest figure on record. Even modest improvements in how quickly you collect from customers can make a meaningful difference to your ability to pay your own bills on time.

Tools like the Xero dashboard give you a real-time view of your cash position, making it easier to spot potential shortfalls early. For a deeper look at strategies, see the guide to managing cash flow.

Be proactive about payment issues

If you're going through a tough period and know you'll struggle to pay a bill on time, reach out to the creditor before the payment is due. Most suppliers and lenders would rather arrange a payment plan than record a default on your file.

Defaults and court judgements can stay on your credit file for years and are difficult to remove. Proactive communication is almost always the better option, and it preserves the supplier relationship at the same time.

Document any arrangements you make in writing, including revised payment dates and any agreed interest or fees, so there's no ambiguity later.

Build strong supplier relationships

Suppliers who offer you trade credit are effectively providing a short-term interest-free loan, and their reports of your payment behaviour can influence your credit score. Consistently paying on time and maintaining open communication builds trust and can encourage suppliers to report positive payment history to credit bureaus.

Strong supplier relationships can also give you more flexibility during difficult periods. A supplier who knows your business well is more likely to work with you on extended terms or payment plans if you need them.

Consider asking your key suppliers whether they report payment data to credit bureaus. If they do, this is another reason to make on-time payment a priority with them specifically.

Keep credit utilisation low

Credit utilisation refers to how much of your available credit you're using at any given time. Keeping this ratio low is a practical way to signal to lenders and bureaus that your business isn't over-reliant on credit.

A good rule of thumb is to keep your credit utilisation below 30%. If you have a business credit card with a $50,000 limit, for example, try to keep the balance below $15,000 at any point in the billing cycle.

If you find your utilisation is consistently high, consider applying for a higher credit limit or spreading balances across multiple accounts, provided you can manage them responsibly. Reducing outstanding balances will also bring utilisation down more quickly than any other single action.

Keep your business finances on track

A healthy business credit score starts with well-organised finances. When your records are accurate and up to date, it's much easier to pay on time, track your credit obligations, and respond quickly when something needs attention.

Xero's online accounting software helps you keep your books in order, with tools for invoicing, bill payments, bank reconciliation, and real-time financial reporting. Clear financial records also make it easier to demonstrate creditworthiness when you're applying for finance or negotiating with suppliers.

You can use Xero to track your business performance and spot issues before they affect your credit profile. Understanding what drives your business finances helps you make decisions with confidence. Find out more about business finance and how it fits into your growth plans. Get one month free

FAQs on business credit scores

Here are answers to some of the most common questions about business credit scores in Australia.

How long does it take to build a business credit score?

Building a credit history typically takes 6 to 12 months of active credit use and consistent on-time payments. The longer your track record of reliable payments, the more complete and useful your credit profile becomes for lenders and suppliers.

Can a poor business credit score affect my personal credit?

For sole traders and small business owners, a poor business credit score can make lenders more likely to assess your personal credit as part of a finance application. If you've provided a personal guarantee for a business loan, a default on that loan can also appear on your personal credit file.

Does closing old business accounts affect my credit score?

Closing a long-standing credit account can shorten your credit history and reduce the diversity of your credit profile, which may lower your score. It's generally better to keep accounts open and in good standing unless there's a specific reason to close them.

How often is my business credit score updated?

Credit bureaus update scores when new information is reported, which can happen monthly or when a significant event occurs, such as a payment default or a new credit enquiry. The frequency depends on how often your creditors and lenders report data to the bureau.

Does applying for a business loan affect my credit score?

Each formal loan application typically triggers a hard credit enquiry, which stays on your file for up to 5 years. Using a mortgage broker or requesting pre-qualification (a soft check) before applying formally can reduce the number of hard enquiries on your file.

Who can see my business credit score?

Any party with a legitimate business purpose can request your business credit report, including lenders, suppliers, landlords, and prospective business partners. Unlike personal credit reports, businesses do not need your consent to access your business credit file in many circumstances, so maintaining a strong score is important.
