Business credit is not one number. Experian Business and Equifax Business keep separate commercial files, use different identifiers and scoring models, and may receive different trade or public-record updates. A value on one bureau’s scale cannot be translated into the other bureau’s scale by arithmetic — and neither score is an approval promise.
This primer maps the labels founders are most likely to see, what the bureaus say their models measure, and the file-building habits that make an entity easier to match. The goal is a clean, readable EIN file across both bureaus — not a promised score, funding amount, approval, or no-personal-guarantee outcome.
What business credit scores are — and why the bureaus disagree
A business credit file describes a legal entity’s commercial identity and reported obligations. For an LLC or corporation, that usually means the entity’s legal name, address, phone, EIN, bureau identifiers, trade accounts, public records, and business background. It is a different surface from a consumer FICO score, although some commercial products can blend the owner’s or guarantor’s consumer data into a business risk model. The EIN helps the bureaus and creditors find the entity; it does not make every commercial product EIN-only.
The numbers diverge for ordinary reasons: each bureau receives its own contributors, matches identity differently, observes a different history, and applies a proprietary model to a defined risk question. One score may be oriented toward payment behavior, another toward severe delinquency, and another toward business failure. A score is a risk signal for a stated model and time horizon, not a lender’s complete decision. A lender can also consider its own policy, the application, cash flow, time in business, collateral, industry, and whether a personal guarantee is required.
Compare your entity identity, file presence, and reporting footprint across commercial bureaus. It is an educational readiness view, not a promised score, approval, funding amount, rate, term, or result.
Experian Business — how to read the score on the file
In Experian’s small-business materials, the Experian Business Credit Score is called Intelliscore Plus℠ and is presented on a 1–100 scale: higher generally means lower modeled risk. Experian’s published bands describe 76–100 as low risk, 51–75 as low to medium, 26–50 as medium, 11–25 as medium to high, and 1–10 as high risk. Do not silently merge that scale with Experian’s commercial Intelliscore Plus V3 documentation, which describes a newer score scale aligned with many consumer-style 300–850 scales and offers different model options. Read the model name and report type before interpreting the number.
Experian describes the inputs in categories rather than publishing a simple founder-facing formula. Credit inputs include the number of trade experiences, balances outstanding, payment habits, credit utilization, and trends over time. Public-record inputs include the recency, frequency, and dollar amounts of liens, judgments, or bankruptcies. Demographic or firmographic inputs include years on file, SIC code, and business size. Experian also describes supplier and lender obligations, legal filings, collections, company background, and comparative industry data; its commercial V3 materials say the score data is third-party reported rather than self-reported. A file with too little qualifying information may not generate a score at all.
Freshness is a feed question, not a fixed promise that the number changes every morning. Experian says government and vendor sources can update daily, weekly, monthly, or quarterly; after Experian receives an update, formatting, cleansing, and loading generally take 48–72 hours, while bankruptcy reports are typically available within 24 hours of filing. That means a vendor’s statement date and the date a bureau can display the data may differ. Treat the report as a dated snapshot, and do not invent a score formula from one movement.
Use a pull-anchor-review path: confirm entity identity, organize operating accounts, and add only useful vendor relationships after checking how they report. No score, funding amount, approval, rate, term, or outcome is guaranteed.
Equifax Business — the score family lenders may pull
Equifax’s public small-business report format shows several metrics side by side. The Payment Index is displayed on a 0–100 scale and maps recent payment performance: 90+ is paid as agreed, 80–89 corresponds to 1–30 days past due, 60–79 to 31–60, 40–59 to 61–90, 20–39 to 91–120, and 1–19 to 120 or more days past due. The same report shows a Business Credit Risk Score on a 101–992 scale and a Business Failure Score on a 1,000–1,880 scale; for those risk scores, higher values generally indicate lower modeled risk. Those are different questions, not three ways to display the same score.
The names tell you what to ask. Payment Index is a payment-performance measure based on recently reported financial and non-financial experiences. A Credit Risk Score is a predictive delinquency or charge-off signal, with the exact model and horizon depending on the product. A Business Failure Score addresses the likelihood of business failure or bankruptcy over a stated horizon. Equifax’s current OneScore for Commercial is another commercial delinquency model: its public product sheet describes severe delinquency on a financial account, including 91-or-more-days-past-due accounts, major derogatory events, and bankruptcies within 12 or 24 months after origination. It uses financial and non-financial data, trended data, public records, firmographics, and guarantor data where applicable.
Equifax’s commercial API materials describe near-real-time access to commercial data, but a file still changes only as contributors and public-record sources furnish or correct information. The product, report date, business match, and whether the model is commercial-only or blended all matter. So when a lender says “we pull Equifax,” ask which score name, range, data blend, and prediction horizon it uses. A 101–992 Credit Risk Score is not an Experian 1–100 Intelliscore Plus, and neither one creates a universal lender cutoff.
Use a monitoring routine to check identity matches, new trade data, balances, payment status, inquiries, liens, judgments, and bankruptcies. If something is wrong, document it and dispute it with the bureau or data furnisher; monitoring cannot guarantee a score change.
How to build a file both bureaus can read
Start with identity consistency. Use the exact legal entity name, operating address, phone, website, entity type, and EIN everywhere, then check that the EIN is aligned with the entity’s D-U-N-S record. A D-U-N-S Number is an identifier, not a score, and Experian and Equifax may also show their own bureau identifiers. Keep those records connected, avoid casual name or address variations, and correct a mismatch before applying for credit so a lender is not comparing two versions of the same business.
Next, use real reporting relationships. Open vendor or financial accounts the business actually needs, ask whether the provider reports to Experian Business, Equifax Business, or both, and ask how often it reports. “Reports to business bureaus” is not the same as “reports to every bureau.” Pay according to the agreed terms, keep balances and utilization understandable, and give the file time to accumulate useful history. No vendor stack can force a bureau to generate a score or force a lender to approve an application.
Finally, monitor and correct the record. Review the legal name and EIN match, bureau identifier, trade-line ownership, account status, balances, payment history, public records, and inquiry activity. If a supplier or bureau has the wrong data, save the report date, identify the exact field, attach supporting documents, and follow the applicable dispute process. Recheck after the source has had time to report the correction; a dispute is a process, not an instant score reset.
Before the next application, bring your current reports, report dates, identity matches, and the lender’s exact score name or model if they will share it. We can help you read the file and choose the next step without promising an approval, amount, rate, or no-personal-guarantee outcome.
