Business Credit Score: How It Works, What the Ranges Mean and How to Improve Yours

Your business credit score is a number that lenders, suppliers, and partners use to judge how likely you are to pay your bills on time. Unlike your personal FICO score (which runs 300 to 850), business credit scores use completely different scales depending on which bureau created them. A "good" score at one bureau can look very different from a "good" score at another.

Four major scoring models exist, each with its own range and purpose. Understanding all four is the first step to controlling your cost of capital and your access to business loans, credit lines, and trade credit. If you only track one score, you are flying blind to what most lenders actually see.

The good news is that you can start building a scorable business credit file in as little as 3 to 6 months. A strong profile typically takes 12 to 18 months of consistent, on-time (or early) payments and responsible credit use.

A business credit score rates your company's likelihood of paying debts on time or defaulting. Three major bureaus (Dun & Bradstreet, Experian, and Equifax) each maintain separate files on your business, and the FICO Small Business Scoring Service (SBSS) blends data from all three into a single number used by SBA lenders and banks.

Your scores affect more than loan approvals. Suppliers check them before offering you net-30 or net-60 payment terms. Landlords review them before signing a commercial lease. Insurance companies may factor them into your premiums. A weak business credit profile means you pay more for almost everything.

Unlike personal credit, business credit reports are not covered by the federal law that guarantees free annual reports. That means you need to actively monitor your file, because errors can sit there for years without anyone noticing. Services like Nav, Experian Business Credit Advantage, and D&B Credit Insights offer monitoring at varying price points.

Each bureau uses its own scale. Here is a breakdown of the four scoring models you need to know, with the "good" thresholds that most lenders consider low risk as of 2026.

• Dun & Bradstreet PAYDEX scores range from 1 to 100. A score of 80 or above signals low risk and indicates you pay on time or early. Scores of 50 to 79 reflect moderate risk, and below 50 flags high risk of late payment.
• Experian Intelliscore Plus (V2) ranges from 1 to 100. A score of 76 or above is generally considered good. The newer V3 version uses a 300 to 850 scale similar to personal credit, though most lenders still use V2 as of 2026.
• Equifax Credit Risk Score ranges from 101 to 992 (higher is better). Equifax also provides a Payment Index (0 to 100, with 90+ indicating all bills paid on time) and a Business Failure Score (1,000 to 1,880, with scores above 1,570 considered low risk).
• FICO SBSS ranges from 0 to 300. The SBA raised its minimum SBSS requirement for 7(a) small loans from 155 to 165 in June 2026. Most banks set internal thresholds at 175 to 180 for serious consideration. Scores of 220+ are often treated as low risk with expedited underwriting.

The FICO SBSS is unique because it blends your personal credit history with business credit data, financial statements, and application details. If your personal credit is weak, it can pull your SBSS down even if your business payment record is excellent.

Building a business credit score follows a predictable path. The initial setup (legal entity, EIN, D-U-N-S Number) takes 1 to 30 days. Your first scorable file can appear within 3 to 6 months once you have active tradelines. A strong credit profile typically takes 12 to 18 months of consistent on-time or early payments, and excellent credit can take 2 to 3 years.

The detailed steps below walk you through the process from zero to a strong score. Each step includes the cost, timeline, and where to go. If you already have some business credit history, skip to the step that matches your current stage (for example, jump to monitoring if you already have tradelines).

One critical point: D&B's PAYDEX score rewards early payments, not just on-time ones. Paying invoices before the due date pushes your score above 80. Simply paying on the due date only gets you to 80. Keep credit utilization below 30% across all revolving accounts to help your Experian and Equifax scores.

Checking your own business credit does not hurt your score. It counts as a soft inquiry. But unlike personal credit, you often have to pay for access. Here are the real costs as of 2026.

Experian's Business Credit Advantage subscription costs $199 per year and includes unlimited report access, email alerts on changes, and dark web monitoring (source: Experian). A single Experian business credit report costs $39.95 without a subscription.

D&B's CreditBuilder Plus costs $149 per month (or $1,499 per year) and lets you submit trade references and monitor your PAYDEX score with alerts (source: Nav review of D&B CreditBuilder). D&B also offers a free tier through D&B Credit Insights that gives limited access to some scores.

Multi-bureau tools like Nav let you see summary scores from multiple bureaus for free, with detailed reports starting at $49.99 per month under the Nav Business Boost plan. If you purchased individual reports from each bureau separately, you could easily spend $250+ for a single snapshot.

You can access your business credit data through the following services. Each covers different bureaus, so using more than one gives you the most complete picture.

• Dun & Bradstreet (D&B Credit Insights) offers a free tier with limited score visibility and paid plans for full PAYDEX access and alerts. You must have a D-U-N-S Number (free to register).
• Experian (smallbusiness.experian.com) sells individual reports at $39.95 each and its Business Credit Advantage monitoring plan at $199 per year. It tracks Intelliscore Plus and Financial Stability Risk Rating.
• Equifax provides business credit reports, including the Credit Risk Score, Payment Index, and Business Failure Score. You can access reports through select business credit monitoring services.
• Nav (nav.com) aggregates summary-level scores from D&B, Experian, and Equifax into a single dashboard, with free and paid tiers.
• FICO SBSS cannot be pulled directly by you. Only lenders can access your SBSS score during a loan application. You can improve it indirectly by strengthening both your personal and business credit profiles.

If your scores are below the "good" thresholds (below 80 PAYDEX, below 76 Intelliscore, or below 165 SBSS), you still have funding options. You just need to match the right product to your current profile.

• Invoice factoring is based on your customers' creditworthiness, not yours. If you have outstanding invoices from reliable clients, a factoring company advances 80% to 90% of the invoice value upfront. Learn more in our invoice factoring guide.
• Merchant cash advances look at your daily credit card sales rather than your credit score. Expect factor rates of 1.1 to 1.5, which translates to effective APRs far higher than traditional loans. See our merchant cash advance guide for honest cost breakdowns.
• Microloans through the SBA microloan program offer up to $50,000 with more flexible credit requirements. Some intermediary lenders will approve borrowers with personal scores as low as 500 to 620. See our SBA microloan guide.
• Small business grants require no repayment and no credit check. Competition is fierce, but grants for small businesses exist at the federal, state, and private levels.

While you pursue short-term funding, keep building your business credit using the steps above. A few months of on-time tradeline payments can move your score significantly. If your personal credit is also weak, work on both simultaneously since models like FICO SBSS blend the two.

These errors are widespread, and each one can cost you real money in the form of higher rates, denied applications, or missed opportunities.

• Never registering with credit bureaus. If you do not have a D-U-N-S Number, D&B cannot generate a PAYDEX score. Without it, you are invisible to lenders who rely on that data. Getting one is free and takes minutes to start.
• Paying on time instead of early. D&B's PAYDEX score caps at 80 for on-time payments. To score above 80, you must pay before the due date. Many business owners hit a plateau at 80 because they do not realize early payment is the only path higher.
• Ignoring your credit reports. Errors are common on business credit reports, from incorrect addresses to misreported payment data. Failing to review and dispute mistakes can lower your score by dozens of points. Each bureau has its own dispute process.
• Keeping credit utilization above 30%. Experian and Equifax both factor in how much of your available credit you are using. Consistently carrying high balances signals financial stress, even if you make every payment on time.
• Relying only on personal credit. Using personal credit cards for business purchases means none of that activity builds your business credit file. Open accounts specifically in your business name that report to commercial bureaus to build a separate, standalone credit profile. Our guide to building business credit covers this in detail.
