What Business Credit Scores Are
A business credit score is a numerical representation of your company's creditworthiness, similar in concept to a personal FICO score but based on entirely different data and scoring methodologies. While personal credit tracks individual consumers, business credit evaluates commercial entities based on their payment history with suppliers, lenders, and service providers.
Unlike personal credit, which is tightly regulated by the Fair Credit Reporting Act, business credit operates in a less regulated environment. Anyone can access your business credit report without your permission, there is no right to dispute inaccuracies through a standardized process, and scoring models vary significantly across bureaus. This makes understanding and proactively managing your business credit profile even more important.
Lenders use business credit scores alongside personal credit, financial statements, and industry risk assessments to make lending decisions. A strong business credit score can qualify you for higher loan amounts, lower interest rates, and less stringent collateral requirements. A weak or nonexistent score forces you into higher-cost products or outright denial.
The Three Major Business Credit Bureaus
Three primary bureaus maintain business credit data, each with its own scoring system and methodology.
| Bureau | Primary Score | Scale | Key Factors |
|---|---|---|---|
| Dun & Bradstreet | PAYDEX | 0 - 100 | Payment history speed (weighted by dollar volume) |
| Experian Business | Intelliscore Plus | 1 - 100 | Payment trends, credit utilization, company size, industry risk |
| Equifax Business | Business Credit Risk Score | 101 - 992 | Payment history, credit utilization, company age, legal filings |
Dun & Bradstreet PAYDEX
The PAYDEX score is the most widely recognized business credit score. It ranges from 0 to 100 and is based exclusively on payment speed. A score of 80 means you pay on time (within terms). Scores above 80 indicate early payment. Below 80 indicates late payment patterns. The score is weighted by dollar volume, meaning larger invoices paid late hurt more than smaller ones.
To have a PAYDEX score, you must first have a D-U-N-S Number, a unique nine-digit identifier assigned by Dun & Bradstreet. Registration is free through their website. You then need at least three trade experiences (vendor accounts reporting payment data) before a PAYDEX score is generated.
Experian Intelliscore Plus
Intelliscore Plus is more comprehensive than PAYDEX, incorporating payment behavior, credit utilization, company demographics, and public records (liens, judgments, bankruptcies). The score ranges from 1 to 100, with 76+ considered low risk. Experian also provides a Financial Stability Risk Score that predicts the likelihood of severe financial distress.
Equifax Business Credit Risk Score
Equifax uses a scale of 101 to 992, with higher scores indicating lower risk. Their model incorporates payment data, credit utilization, company size, years in business, and industry risk factors. Equifax also provides a Business Failure Score predicting the probability of a business ceasing operations.
How Business Credit Scores Are Calculated
While each bureau uses proprietary algorithms, the core inputs are consistent across all three.
Payment History (Most Important)
How quickly and consistently you pay your obligations is the dominant factor. Payment behavior is typically categorized as prompt (within terms), 1 to 30 days late, 31 to 60 days late, 61 to 90 days late, or 90+ days late. A single late payment can significantly impact your score, especially on high-dollar accounts.
Credit Utilization
The percentage of your available credit that you are currently using. Lower utilization signals that you manage credit responsibly and are not overleveraged. Keep utilization below 30% across all revolving accounts for optimal scoring impact.
Company Profile
Older companies with more employees and higher revenue generally score better because they have more established track records. This factor rewards operational stability and longevity.
Public Records
Tax liens, judgments, collections, and bankruptcies severely damage business credit scores. A single tax lien can drop your score by 30 to 50 points and take years to recover from. UCC filings (indicating secured loans) can also affect scores, though their impact is less severe.
Industry Risk
Some scoring models incorporate industry risk assessments. Businesses in high-default industries like restaurants and construction may start with a slight scoring disadvantage compared to lower-risk sectors like professional services or healthcare.
Business vs. Personal Credit
| Dimension | Personal Credit | Business Credit |
|---|---|---|
| Score Range | 300 - 850 (FICO) | 0 - 100 (PAYDEX/Intelliscore) or 101 - 992 (Equifax) |
| Regulation | FCRA regulated; strong consumer protections | Minimal regulation; fewer dispute rights |
| Access | Requires your authorization (hard/soft pull) | Publicly accessible; no authorization needed |
| Data Sources | Banks, credit cards, loans, utilities | Trade vendors, banks, public records, UCC filings |
| Building Time | Starts at 18 (thin file) | Starts when you register DUNS + open trade lines |
How to Build Business Credit from Scratch
If your business does not yet have a credit profile, follow this sequence to establish one efficiently.
- Formalize your business structure: Incorporate as an LLC, S-Corp, or C-Corp. Obtain an EIN from the IRS. Open a dedicated business bank account. These are prerequisites for establishing a separate business credit identity.
- Register with Dun & Bradstreet: Apply for a free D-U-N-S Number at dnb.com. This is the foundation of your business credit profile.
- Open net-30 trade accounts: Start with vendors known to report to credit bureaus. Common starter accounts include office supply companies, fuel cards, and industrial suppliers. You need at least three reporting trade lines to generate a PAYDEX score.
- Get a business credit card: Choose a card that reports to business credit bureaus (not all do). Use it regularly and pay the full balance each month.
- Pay everything early: For the first 12 months, pay every invoice as early as possible. Early payment is the fastest way to build a PAYDEX score above 80.
- Monitor your reports: Check your business credit reports quarterly to ensure all trade lines are reporting correctly and no errors have appeared.
Strategies to Improve Existing Scores
If you already have business credit but need to improve your scores before applying for financing, focus on these high-impact actions.
Quick Wins (Impact in 30 to 90 Days)
- Pay down outstanding balances: Reducing utilization creates immediate scoring improvement
- Resolve any late payments: Bring all accounts current and maintain on-time payment going forward
- Dispute errors: Contact bureaus directly to correct inaccurate data (wrong addresses, misattributed debts, incorrect payment status)
- Ask vendors to update reporting: If you have made recent early payments, request that vendors update their reported data
Medium-Term Improvements (3 to 12 Months)
- Add more reporting trade lines: More positive data points improve scoring across all models
- Resolve public records: Pay and release any tax liens or judgments. File satisfaction documents with the court and ensure bureaus update accordingly
- Establish a consistent payment pattern: Scoring models weight recent behavior more heavily than older history
Monitoring and Protecting Your Credit
Business credit monitoring is less convenient than personal credit monitoring but equally important.
- Set quarterly review reminders: Check all three bureau reports every 90 days, minimum
- Use monitoring services: Dun & Bradstreet CreditMonitor, Nav.com, and Experian Business all offer alert services for changes to your profile
- Watch for identity theft: Business identity theft is growing rapidly. Fraudulent accounts opened in your business name damage your credit and can take months to resolve
- Protect your D-U-N-S number: Treat it with the same care as your EIN. Do not share it unnecessarily
Your business credit score is not just a number. It is the financial reputation of your company, visible to lenders, suppliers, landlords, and potential partners. Building and protecting it is one of the highest-ROI investments a business owner can make.
