Business Credit Scores, Decoded: PAYDEX, Intelliscore, and FICO SBSS Explained
Business Credit Scores, Decoded: PAYDEX, Intelliscore, and FICO SBSS Explained
Your business has more than one credit score — and unlike personal credit, the models barely agree on a scale, let alone a number. A lender pulling your file might see a PAYDEX, an Intelliscore, an SBSS, and an Equifax score, each saying something different. Here is what each one actually measures, the ranges that matter, and how to move all of them in the right direction.
What you'll learn
Why business scores are different
Personal credit has effectively standardized around two models on a familiar 300–850 scale. Business credit never did. Each bureau built its own model on its own scale to answer its own question, and a lender may pull several at once. That fragmentation is exactly why so many founders feel they "don't know their business score" — there isn't one score, there are several, and they don't speak the same language.
The good news is that the same underlying behaviors move all of them. Once you understand what each model rewards, a single disciplined approach — pay early, build depth, keep records clean — lifts the whole set. This guide assumes you've already established a file; if you're starting from zero, begin with our business credit playbook and the guide to building credit on your EIN rather than your SSN.
PAYDEX (Dun & Bradstreet)
The PAYDEX score, from Dun & Bradstreet, runs from 0 to 100 and is the most widely cited business credit score. Its defining feature is simplicity: it is driven almost entirely by how promptly you pay, weighted by the dollar size of each tradeline. Critically, "on time" is not the ceiling — paying ahead of terms is what pushes the score into the 80s and above.
- 80–100: Payments made on or before terms — the target zone.
- 50–79: Payments running modestly late.
- 0–49: Significantly late payments; a red flag to lenders.
Because PAYDEX rewards early payment so directly, it's the score most responsive to disciplined vendor management — and the reason "pay early, not just on time" is the first rule of business credit.
Intelliscore Plus (Experian)
Experian's Intelliscore Plus takes a different approach. Running from 1 to 100, it is a statistical risk score built to predict the likelihood of serious delinquency over the coming months. Rather than measuring payment promptness alone, it weighs a broader set of factors — payment history, credit utilization, the depth and age of your tradelines, public records, and more — and distills them into a single risk-ranked number, where higher means lower risk.
The practical difference matters: you can have a strong PAYDEX from paying early while still carrying risk signals — high utilization, a thin file, a recent public record — that pull your Intelliscore down. Managing one score well doesn't guarantee the other. Lenders often look at both precisely because they answer different questions: do you pay promptly, and how likely are you to default.
FICO SBSS (SBA lending)
The FICO Small Business Scoring Service (SBSS) score is the one that surprises founders most, because it breaks the wall between business and personal credit. Running from 0 to 300, SBSS blends business credit data with the business owner's personal credit — and sometimes business financials — into one score. It matters enormously because the U.S. Small Business Administration and many banks use it to screen small business and 7(a) loan applications. Lenders frequently look for a minimum SBSS of around 155 to pass an initial screen, though many set their bar higher.
The key takeaway is counterintuitive but important: even as you build credit that lives on your EIN, the owner's personal credit still influences this particular business score. For SBA-track financing, neglecting your personal credit can quietly cap your business borrowing.
Equifax business scores
Equifax rounds out the three major business bureaus with its own suite, typically including a payment-focused index, a business credit risk score that predicts delinquency, and a business failure score that estimates the likelihood the business closes with unpaid obligations. The scales differ again from the others — which is the whole point of monitoring all three bureaus rather than fixating on a single number. A lender you approach may pull Equifax specifically, and a gap or error there can cost you an approval you'd otherwise win.
| Score | Source | Range | Measures |
|---|---|---|---|
| PAYDEX | Dun & Bradstreet | 0–100 | Payment promptness |
| Intelliscore Plus | Experian | 1–100 | Delinquency risk |
| FICO SBSS | FICO (SBA) | 0–300 | Blended business + personal risk |
| Business Risk / Failure | Equifax | Varies | Delinquency & closure risk |
Build the file every score reads from

How to improve every score
- Pay reporting vendors early. The fastest lever for PAYDEX and a positive signal for every model.
- Add reporting tradelines. Depth and breadth strengthen risk-based scores like Intelliscore and the Equifax suite.
- Keep utilization low. High balances against limits raise perceived risk.
- Keep public records clean. Liens, judgments, and late filings weigh heavily on risk and failure scores.
- Protect personal credit for SBSS. Because SBSS blends in personal data, the owner's score still matters for SBA-track loans.
- Monitor all three bureaus. Confirm reporting, catch errors, and know which score a given lender will see.
Watch all three scores in one place

Frequently asked questions
It depends on the model. For PAYDEX (0–100), 80+ signals on-or-before-terms payment. For Intelliscore Plus (1–100), higher means lower risk, with scores above roughly 76 considered low risk. For FICO SBSS (0–300), lenders often look for 155+ to pass an initial SBA screen. There's no single universal number.
PAYDEX is a payment score driven mainly by how promptly you pay — early payment lifts it above 80. Intelliscore Plus is a broader, risk-based score predicting the likelihood of serious delinquency. PAYDEX rewards early payment; Intelliscore predicts risk.
FICO SBSS is a 0–300 score blending business credit data with the owner's personal credit and sometimes financials. The SBA and many banks use it to screen small business and 7(a) applications, often requiring a minimum to proceed — so strong personal credit still influences this business score.
Pay reporting vendors early, add reporting tradelines, keep utilization low, avoid liens and judgments, protect the owner's personal credit for SBSS, and monitor all three business bureaus. Different scores weigh different inputs, so manage payment behavior, file depth, and public records together.
Key takeaways
- Business credit isn't one score — PAYDEX, Intelliscore, SBSS, and Equifax each use their own scale.
- PAYDEX rewards early payment; Intelliscore predicts risk; SBSS blends in personal credit.
- FICO SBSS gates much SBA lending, so personal credit still matters for business loans.
- The same disciplined behaviors lift every score at once.
- Monitoring all three bureaus tells you which score a lender will actually see.
