Personal credit scores — FICO scores on a 300–850 scale — are widely understood. Most people know that 750 is good and 580 is going to be a problem. Business credit scores are a different story entirely. There are three major bureaus, three different scoring models, three different scales, and the vast majority of small business owners have never checked any of them. Yet every commercial lender, supplier, insurer, and major vendor uses these scores to make decisions about your business. Here's the complete guide to understanding, monitoring, and improving all three of your business credit scores.
The Three Business Credit Bureaus
Business credit is reported and scored by three primary bureaus: Dun & Bradstreet (D&B), Experian Business, and Equifax Business. Each maintains a separate file on your business, collects data from different sources, and uses a different scoring model. A lender may check one, two, or all three — it varies by lender type and loan product.
| Bureau | Primary Score | Score Scale | What It Measures |
|---|---|---|---|
| Dun & Bradstreet | PAYDEX Score | 1–100 | Payment timing relative to vendor terms |
| Experian Business | Intelliscore Plus | 1–100 | Payment history, utilization, public records |
| Equifax Business | Business Credit Risk Score | 101–992 | Payment history, delinquency risk, financial stress |
| Equifax Business | Business Failure Score | 1000–1880 | Probability of business closure within 12 months |
Dun & Bradstreet PAYDEX Score: The Most Widely Used
The PAYDEX score is the most recognized business credit score in commercial lending. It measures one thing: how promptly your business pays its vendor bills relative to the agreed terms. A score of 80 means you pay exactly on time. Higher scores reflect early payment. Lower scores reflect late payment.
| PAYDEX Score | Payment Behavior | Lender Interpretation |
|---|---|---|
| 100 | Payment 30+ days early | Exceptional — rare and highly favorable |
| 90–99 | Payment 14–30 days early | Excellent — best available credit terms |
| 80 | Payment exactly on due date | Good — standard approval; favorable rates |
| 70–79 | Payment 1–15 days late | Average — may see higher rates or lower limits |
| 50–69 | Payment 16–30 days late | Below average — limited to alternative lenders |
| Below 50 | Payment 30+ days late | Poor — significant barriers to approval |
D&B requires a minimum of three trade references reporting to calculate a PAYDEX score. This is why vendor tradeline building is the first step in any business credit strategy — without three reporting accounts, you don't have a PAYDEX score at all. To build your D&B file, you must first obtain a DUNS Number from Dun & Bradstreet (free at dnb.com). Then add at least three vendor accounts from Tier 1 suppliers that report to D&B.
Experian Intelliscore Plus: The Multi-Factor Score
Experian's Intelliscore Plus is more complex than PAYDEX because it evaluates multiple factors beyond payment timing. It considers your payment history (how often you pay late), the recency of any delinquencies, public records (liens, judgments, bankruptcies), credit utilization on revolving accounts, the number of accounts you have, and the length of your credit history.
The Intelliscore Plus scale runs 1–100, with higher scores representing lower risk. Many lenders use 76+ as a "strong" benchmark. Scores below 25 are classified as high risk. Unlike PAYDEX which is purely payment-timing based, a single serious delinquency or public record can significantly damage your Intelliscore.
Key Difference from PAYDEX: Experian weighs negative events more heavily than D&B. A tax lien, judgment, or collection account that barely affects your PAYDEX can dramatically drop your Intelliscore. Check your Experian Business report for public records before applying for financing.
Equifax Business Scores: Two Scores, Two Risk Signals
Equifax provides two scored metrics: the Business Credit Risk Score (101–992), which assesses the likelihood of seriously delinquent payment, and the Business Failure Score (1000–1880), which assesses the likelihood of business closure within 12 months. Lenders use both, but the Credit Risk Score is more commonly referenced in loan underwriting.
A Business Credit Risk Score above 556 is generally considered satisfactory. Below 452, lenders see elevated delinquency risk. The Business Failure Score is most commonly used by trade creditors extending net-30 or net-60 terms — a score near 1000 indicates higher failure risk while a score near 1880 suggests very low failure probability.
How to Build All Three Scores Strategically
| Action | Affects PAYDEX | Affects Intelliscore | Affects Equifax | Timeline |
|---|---|---|---|---|
| Get DUNS Number | Required prerequisite | No direct effect | No direct effect | Immediate (free) |
| Add 3+ Tier 1 vendor tradelines | Creates PAYDEX score | Adds payment history | Adds payment history | 60–90 days to report |
| Pay all vendor invoices early | Pushes PAYDEX above 80 | Improves delinquency metric | Reduces risk score | Ongoing |
| Open business credit card | Minor effect | Adds utilization data point | Adds revolving history | 30 days to report |
| Resolve open liens / judgments | Moderate improvement | Significant improvement | Significant improvement | 30–60 days post-release |
| Dispute and correct errors | Varies by error type | Varies by error type | Varies by error type | 30–45 days |
How to Monitor Your Business Credit Scores
Unlike personal credit where annualcreditreport.com provides free annual reports, business credit monitoring requires paid subscriptions or direct bureau access. Here are the current options:
- D&B: CreditBuilder Plus or CreditMonitor ($149–$199/month) — also accelerates tradeline reporting and alerts you to score changes
- Experian Business: BusinessIQ plan (starting around $39.95/month) — provides your Intelliscore Plus and business credit report
- Equifax Business: Navigate by Equifax for Business — available through select partners; direct access is limited for small businesses
- Nav.com: Aggregates all three bureau scores in one dashboard with free and paid tiers — excellent starting point for most small business owners
- Credit-building platforms: Our credit-building software monitors all three bureaus and provides a prioritized action plan for improving each score
Recommended Practice: Monitor all three scores at least quarterly. Before any major loan application, pull fresh reports from all three bureaus and resolve any errors first. A lender declining you based on a data error is 100% preventable.
