[.green-span]PAYDEX vs Intelliscore vs FICO SBSS: which score should lenders use?[.green-span]
The short answer: match the score to the decision
Lenders comparing PAYDEX vs Intelliscore vs FICO SBSS often want one winner. No single score wins every credit decision, because each one predicts a different outcome.
The SBA raised the stakes in 2026. Effective March 1, 2026, the SBA discontinued SBSS for 7(a) Small Loan underwriting, so SBSS is no longer the default gate.
Use PAYDEX for trade and payment behavior. Use Experian Intelliscore Plus for 12-month delinquency risk that blends owner data. Use SBSS where your program still uses or blends it, then combine scores with cash-flow analysis.
This guide covers each score, a side-by-side table, the new 7(a) Small requirements, thresholds, and a six-step framework.
PAYDEX vs Intelliscore vs FICO SBSS at a glance
Each score answers a different underwriting question. Use the table below to see which one fits your decision.
Read the table by column. Compare "What it predicts" with your loss event, then check "Key inputs" to see whether the score sees owner credit.
Know what each business credit score predicts
The three scores share a name category but measure different risks. Here is how each one works from the lender's side.
1. Dun & Bradstreet PAYDEX measures trade payment behavior
PAYDEX is a payment-timeliness score on a scale up to 100. Per Nuvo, 80–100 means on time or early, 50–79 means 15–30 days late, and 0–49 means more than 31 days late.
The scale rewards early payment. PaySimple notes that paying on the due date tops out at 80, while 100 requires paying about 30 days early.
PAYDEX is strictly business and covers payment behavior only. It requires a D-U-N-S number and trade references reported to D&B, and PaySimple says at least four reporting suppliers. That makes it a strong fit for trade and supplier terms.
2. Experian Intelliscore Plus predicts 12-month delinquency risk
Intelliscore Plus uses a 1–100 scale and predicts the likelihood of serious delinquency in the next 12 months. Nuvo lists five risk classes:
- 76–100 is low risk
- 51–75 is low-medium risk
- 26–50 is medium risk
- 11–25 is medium-high risk
- 1–10 is high risk
Inputs go well beyond payments. According to America's SBDC, the model weighs tradelines, collections, recent inquiries, public filings, new account activity, and key financial ratios. It also blends commercial and owner credit variables.
3. FICO SBSS blends consumer, business, and application data
FICO SBSS uses a 0–300 scale, and a higher score means lower risk. Nav explains that it blends consumer credit from Equifax, Experian, and TransUnion with business bureau data from D&B, Experian, and Equifax, including SBFE data.
SBSS also pulls in lender application data and financials. It predicts major delinquency, charge-off, and bankruptcy, and lenders use it to evaluate loans up to $1M.
Lenders can configure its parameters. Business owners can't buy it directly, which matters when borrowers ask why they were declined.
How does it differ from Intelliscore Plus? Intelliscore Plus draws on Experian data and forecasts a 12-month window. SBSS combines several bureaus with application data and financials, and lenders can tune it.
4. Equifax scores and SBFE data fill in bank-lender history
Equifax adds two more scores. Per Nuvo, the Business Credit Risk Score runs 101–992 and predicts delinquency, and the Business Failure Score runs 1,000–1,880 and predicts 12-month closure.
The Small Business Financial Exchange (SBFE) is a member-owned exchange that doesn't issue scores. Nav notes that it licenses lender payment data to D&B, Equifax, Experian, and LexisNexis.
Plan for the SBSS sunset in SBA 7(a) Small Loans
The sunset changes how SBA lenders gate small loans. Here is what changed and what replaces the old cutoff.
What changed on March 1, 2026
SBA tightened SBSS before retiring it. Nav reports that the minimum rose from 140 to 155 in October 2020, then to 165 in June 2025. The small-loan ceiling also dropped from $500K to $350K in June 2025.
Procedural Notice 5000-876777 ended SBSS use for 7(a) Small Loan underwriting, effective March 1, 2026. NAGGL reports the notice was issued February 20, 2026, and replaced Notice 5000-875701 from January 16, 2026. The change covers small loans up to the $350K ceiling, per Nav.
What SBA now requires for 7(a) Small Loans
Per NAGGL, the new standard includes:
- A full commercial credit analysis.
- A credit history review covering the applicant, operating company, associates, and guarantors.
- Use of the lender's conventional-loan scoring model, if its primary federal regulator permits it and it doesn't rely solely on consumer scores.
- Own-model use for SBLCs, subject to SBA review.
- A minimum debt service coverage ratio (DSCR) of 1.1x, also noted by Lumos Data.
Where SBSS still fits
SBSS still exists, and lenders can still use it. FastWaySBA confirms lenders are free to keep using SBSS and aren't required to stop, and FRANdata notes SBA Express is not affected.
Read thresholds and personal credit in context
A cutoff only works if you know what the score measures. Set thresholds by score band and pair them with owner credit.
Score thresholds lenders work with
- A PAYDEX of 80 or higher signals on-time or early payment, per Nuvo's bands.
- An Intelliscore Plus of 76–100 is the lowest-risk class for 12-month delinquency.
- Some lenders accept SBSS scores of 160–180, while others require 180 or higher, per Nav.
- An SBSS of 165 was the SBA 7(a) Small Loan floor until the March 2026 sunset.
A PAYDEX of 80 means a business pays on the due date. Treat it as a clean payer, since only early payment pushes the score higher.
The role of personal credit
Owner credit carries different weight in each score. PAYDEX leaves it out, Intelliscore Plus blends owner variables, and SBSS pulls consumer data from all three bureaus.
The new 7(a) Small rules keep owners in scope. Lenders must review guarantor credit history, and they can't rely solely on consumer scores.
Combine scores in one decision layer with Lendflow
85% faster time-to-decision. That is the outcome Lendflow Intelligence targets as the decisioning layer that turns credit and business data into lending decisions.
Post-sunset, many lenders need their own model in place of a single SBSS gate. Lendflow Intelligence supports that shift with configurable decision models and rules, and it sits between Lendflow Connect and Lendflow Automate.
Lendflow Connect is an embedded lending network that links brands to 75+ lenders through a single integration. Lendflow Automate handles workflow execution, with AI agents for documents and workflow triggers.
A six-step framework for choosing the right score
Use these steps to pick, weight, and govern business credit scores for each product you offer.
Step 1: define the credit decision
Name the decision first: trade line, term loan, line of credit, or SBA 7(a) Small Loan. Each one carries a different loss event and time horizon.
A supplier extending net terms cares about payment timing. A term lender cares about charge-off and bankruptcy over the life of the loan.
Step 2: map each decision to the score that predicts it
Match the outcome to the model. PAYDEX fits payment behavior, Intelliscore Plus fits 12-month delinquency, and SBSS fits blended charge-off and bankruptcy risk.
Step 3: pull business and owner data together
SBA now expects credit history on the applicant, operating company, associates, and guarantors. Pull business bureau scores and owner credit in the same step so files arrive complete.
Step 4: add cash-flow analysis and DSCR
Scores show history, while cash flow shows capacity to repay. For 7(a) Small Loans, SBA sets a 1.1x minimum DSCR, so bank data belongs in every file.
Step 5: set thresholds and exception routing
Set cutoffs by score band for each model. Route files with conflicting signals, such as a strong PAYDEX with a weak Intelliscore Plus, to manual review.
Step 6: document, validate, and review the model
Confirm your primary federal regulator permits your conventional-loan scoring model for SBA use. SBLCs should plan for SBA review of their models.
Keep a written record of each score, threshold, and override rule. That record supports both regulator questions and internal audits.
Best practices for multi-score underwriting
These tips help teams avoid the most common mistakes after the sunset.
Practical recommendations
- Read score bands first. A 75 means different things on PAYDEX and on Intelliscore Plus.
- Check file depth. PAYDEX needs reporting suppliers, so a thin trade file may say little about risk.
- Keep SBSS where it adds signal. It remains allowed and works as one input in a blended model.
- Tie scores to cash flow. Pair every bureau score with bank data to confirm repayment capacity.
- Document your rationale. Record why each score sits in your model and how you weight it.
Common pitfalls to avoid
- Treating PAYDEX 80 as weak. On-time payment tops out at 80, so penalizing it can push out good borrowers.
- Relying only on consumer scores. The new 7(a) Small rules don't allow it.
- Assuming SBA Express changed. FRANdata notes Express is not affected by the sunset.
- Ignoring SBFE coverage. Bank-lender payment data reaches D&B, Equifax, and Experian through SBFE licensing.
Conclusion: match scores to decisions, then add cash flow
PAYDEX, Intelliscore Plus, and FICO SBSS each predict a different outcome. PAYDEX tracks trade payment behavior, Intelliscore Plus forecasts 12-month delinquency, and SBSS blends consumer, business, and application data.
Since March 1, 2026, SBSS no longer gates SBA 7(a) Small Loans. Lenders now need full commercial credit analysis, guarantor review, and a 1.1x minimum DSCR.
The takeaway: match each score to the decision, combine multiple scores, and anchor the file in cash flow.
FAQs about PAYDEX, Intelliscore, and SBSS
What is a good FICO SBSS score?
Higher SBSS scores signal lower risk on the 0–300 scale. Nav notes that some lenders accept 160–180 while others require 180 or higher, since each lender sets its own standard. The last SBA 7(a) Small Loan minimum was 165.
What business credit score do most lenders use?
There is no single standard. SBSS was the SBA default for small loans until March 2026, PAYDEX is common for trade terms, and Intelliscore Plus covers 12-month delinquency risk.
Can business owners see their FICO SBSS score?
Not directly. FICO doesn't sell SBSS to business owners, so it remains a lender-side score.
What does a PAYDEX score of 100 require?
A PAYDEX of 100 requires paying about 30 days early. Paying on the due date tops out at 80.
How does the SBSS sunset affect lenders?
SBA lenders can no longer use SBSS as the 7(a) Small Loan gate. They need full commercial credit analysis, guarantor review, a 1.1x DSCR, and a permitted scoring model.
