Business Credit Scores Decoded: Paydex, Intelliscore, and FICO SBSS

Why Multiple Business Credit Scores Exist

Unlike personal credit, where FICO and VantageScore dominate a relatively unified landscape, business credit is assessed through several distinct scoring models maintained by competing bureaus and analytics firms. Understanding which score a lender or supplier is likely to consult—and what that score actually measures—is foundational knowledge for any business seeking financing or favorable trade terms.

For a broader orientation on how business credit differs from personal credit, see Business Credit Explained. This article focuses specifically on the three scoring models that appear most frequently in lending and supplier decisions: Paydex, Intelliscore Plus, and FICO SBSS.

Paydex: Dun & Bradstreet's Payment Promptness Score

The Paydex score is the signature metric of Dun & Bradstreet (D&B) and is one of the most widely referenced scores in trade credit decisions. It measures a single, specific dimension: how quickly a business pays its bills relative to agreed terms.

• Range: 1 to 100
• Score of 80: Payment made exactly on the due date
• Score of 100: Payment made 30 or more days early
• Score of 70: Payment made up to 15 days late

To generate a Paydex score, a business must have a D-U-N-S Number and at least three trade lines reported to D&B. Paydex is dollar-weighted, meaning larger transactions carry more influence on the score than smaller ones. A business that pays its largest invoices promptly but is slow on minor accounts will generally score better than the reverse.

Suppliers and vendors extending net-30 or net-60 payment terms frequently check Paydex before setting credit limits. It does not factor in debt levels, revenue, or litigation history—those are captured in separate D&B reports.

Intelliscore Plus: Experian's Predictive Delinquency Model

Experian's Intelliscore Plus takes a broader predictive approach. Rather than measuring only payment speed, it estimates the probability that a business will become severely delinquent on a financial obligation within the next 12 months.

• Range: 1 to 100 (higher is better)
• Score of 76–100: Low risk
• Score of 51–75: Low-to-medium risk
• Score of 26–50: Medium-to-high risk
• Score of 1–25: High risk

Intelliscore draws from over 800 variables, including business payment history, credit utilization, public records such as liens and judgments, and—notably—the owner's personal credit data. This blended approach reflects the reality that small business financial behavior and owner behavior are often intertwined. Understanding how credit utilization affects business scoring is particularly relevant here, since Intelliscore weighs revolving credit balances relative to limits.

FICO SBSS: The Blended Score Used in Lending Decisions

The FICO Small Business Scoring Service (SBSS) is distinct from the other two models in both its data inputs and its primary application. It is designed explicitly for lenders evaluating small business loan applications.

• Range: 0 to 300 (higher is better)
• Data inputs: Business credit bureau data, personal credit of the owner(s), and—in some versions—basic financial statement data
• Primary use: Pre-screening for SBA loans and bank term loans

The SBA uses FICO SBSS as a pre-screen filter for certain loan programs, with lenders commonly applying minimum thresholds around 155, though this varies by institution and program. Crossing the threshold does not guarantee approval; it simply determines whether a full manual underwrite is triggered. Scores below the threshold typically result in automatic disqualification from the pre-screen process.

Because SBSS blends personal and business credit, businesses with thin commercial credit files can still achieve competitive scores if the owner's personal credit is strong—and vice versa. This makes it one of the most consequential scores to understand when pursuing business loan options.

Practical Implications: Monitoring and Maintaining Your Scores

Because each scoring model draws on different data and serves different decision contexts, a business cannot rely on a single score to represent its full creditworthiness. A strong Paydex score built on prompt supplier payments does not automatically translate into a favorable Intelliscore or SBSS result.

Key practices for managing across all three models include:

1. Register a D-U-N-S Number early and cultivate at least three reporting trade lines to establish a Paydex baseline.
2. Keep revolving credit utilization low on business accounts, as this directly influences Intelliscore Plus and SBSS calculations.
3. Monitor for errors across Dun & Bradstreet, Experian Business, and Equifax Business reports. Inaccurate public records or misreported trade lines can suppress scores across multiple models. Business Credit Monitoring outlines what to track and how often.
4. Maintain the owner's personal credit for businesses where SBSS or Intelliscore may blend individual credit history into the evaluation.
