Most business owners know their personal FICO score by heart. But ask them about their PAYDEX score, their Experian Intelliscore, or their Equifax Business Credit Risk Score — and you'll usually get a blank stare. This knowledge gap costs businesses real money every year in higher interest rates, declined applications, and missed opportunities. Understanding how business credit bureaus score is one of the highest-leverage things you can do for your financial future.
Key Difference: Unlike personal credit, your business credit reports are publicly accessible — meaning suppliers, competitors, landlords, and potential partners can all pull your business credit profile without your permission. What they see matters.
The Three Major Business Credit Bureaus
Just as personal credit has Equifax, Experian, and TransUnion, business credit has three primary bureaus — each with its own scoring model, data sources, and scale. A lender may check one, two, or all three when evaluating your application. Here's what each one measures and how to optimize for them.
Bureau #1: Dun & Bradstreet — The PAYDEX Score
Dun & Bradstreet (D&B) is the oldest and most widely recognized business credit bureau in the world, serving over 200 countries. Their flagship score is the PAYDEX score, which ranges from 1 to 100 and measures one thing with laser focus: how promptly your business pays its bills.
| PAYDEX Score | Payment Behavior | What It Means to Lenders |
|---|---|---|
| 100 | Pays 30 days early | Exceptional — best possible rate |
| 90–99 | Pays 20 days early | Excellent borrower |
| 80 | Pays exactly on time | Good standing — standard approvals |
| 70–79 | Pays up to 15 days late | Marginal — higher rates likely |
| 50–69 | Pays 16–30 days late | Poor — many lenders will decline |
| Below 50 | Pays 60+ days late | High risk — very limited options |
To generate a PAYDEX score, D&B requires at least 3 trade experiences reported to their bureau. This is why opening net-30 vendor accounts that report to D&B is the essential first step in business credit building.
How to Maximize PAYDEX: Pay all vendor invoices 5–15 days early. A score of 80 (on-time) is good; a score of 100 (30 days early) is exceptional and signals to lenders that your business manages cash extremely well.
Beyond PAYDEX, D&B also produces a Delinquency Predictor Score (likelihood of late payment in the next 12 months) and a Financial Stress Score (probability of business failure). Lenders often consider all three together.
Bureau #2: Experian Business — The Intelliscore Plus
Experian Business is the most data-rich of the three bureaus, pulling from both business payment history and personal credit data to create a comprehensive risk picture. Their primary score is the Intelliscore Plus, which ranges from 1 to 100.
What makes Experian's model unique is that it considers over 800 variables, including:
- Trade payment history (vendor accounts, supplier invoices)
- Business bank account information
- Collection records and judgments
- Length of time in business
- Industry-specific risk factors
- The owner's personal credit history (weighted, but included)
Because Experian blends personal and business data, maintaining a strong personal credit score genuinely helps your Intelliscore — especially in the early stages of business credit building.
Bureau #3: Equifax Business — Multiple Scores
Equifax Business takes a different approach by providing several distinct scores rather than one primary number. Their most commonly referenced metrics are the Business Credit Risk Score (101–992) and the Business Failure Score (1,000–1,880).
| Score Type | Range | What It Predicts |
|---|---|---|
| Business Credit Risk Score | 101–992 | Probability of serious delinquency (90+ days late) in next 12 months. Higher = lower risk. |
| Business Failure Score | 1,000–1,880 | Probability the business will close or file for bankruptcy. Higher = lower risk. |
| Payment Index | 0–100 | Similar to PAYDEX — measures payment timeliness over the past 12 months. |
Equifax draws data from their extensive database of trade lines, public records (liens, judgments, bankruptcies), and banking relationships. Lenders using Equifax Business reports are often mid-size and regional banks, as well as equipment financing companies.
Key Differences Between Business and Personal Credit
Understanding these distinctions will change how you manage your business finances:
| Factor | Personal Credit | Business Credit |
|---|---|---|
| Score Range | 300–850 (FICO) | 1–100 (PAYDEX), 1–100 (Intelliscore), 101–992 (Equifax) |
| Public Access | Private — only you and authorized parties | Public — anyone can purchase your report |
| Hard Inquiries | Lower your score temporarily | Generally do not affect your score |
| Building Speed | Years to build significantly | 90 days to establish a fundable baseline |
| Dispute Process | Governed by FCRA — strict rules | Less regulated — requires direct bureau contact |
How to Monitor All Three Bureaus
Unlike personal credit (where free monitoring is widely available), business credit monitoring typically requires a paid subscription. Here's the most cost-effective approach:
- Dun & Bradstreet: CreditSignal (free, limited) or D&B Credit (paid, full access)
- Experian Business: BusinessCreditFacts.com or Experian Business Credit Advantage
- Equifax Business: Equifax Business Credit Monitor
- All-in-one option: Nav.com provides access to all three bureaus in one dashboard; our credit-building software also monitors all three and provides a structured action plan for improvement
Important: Errors on business credit reports are more common than most owners realize — and less regulated than personal credit errors. Check all three reports at least twice per year and dispute any inaccuracies directly with the bureau. An error can quietly cost you approvals and good rates for months before you notice it.
The Bottom Line: Your business credit scores are working for or against you right now — whether you're paying attention to them or not. Lenders, suppliers, and partners are checking them. The businesses that take control of their credit profiles are the ones that secure better rates, higher limits, and more options. Start monitoring today.
