Quick answer: Business credit scores are separate from your personal FICO and come from three primary sources: FICO SBSS (0–300, used by SBA lenders), Dun & Bradstreet Paydex (1–100, based on payment timing), and Experian Business Intelliscore (1–100, similar to personal FICO modeling). Each is calculated differently, used for different purposes, and can be improved independently. For most small business lending, personal FICO still carries the most weight — but FICO SBSS matters for SBA loans, and Paydex matters for trade credit and vendor relationships.

Most business owners know their personal FICO score. Far fewer understand their business credit scores — or even that their business has separate credit scores maintained by multiple bureaus. This gap matters because business credit scores affect which loans you qualify for, what rates you pay, and whether your business can access trade credit from vendors. This guide explains each of the three major business credit scoring systems, how they are calculated, what score ranges mean for lending outcomes, and how to build business credit from scratch.
Personal credit scores and business credit scores coexist as separate systems with different rules, different data sources, and different purposes. Understanding the distinction prevents confusion and helps you focus improvement efforts in the right place.
Personal credit (FICO): Maintained by Equifax, Experian, and TransUnion. Based on your individual borrowing history — credit cards, auto loans, mortgages, student loans, personal loans. Ranges from 300 to 850. Access to your own report is protected by the Fair Credit Reporting Act (FCRA). Errors can be disputed with legal protections. You are entitled to free annual reports from each bureau.
Business credit: Maintained by Dun & Bradstreet, Experian Business, Equifax Business, and FICO (for the SBSS product). Based on the business entity's payment history with trade creditors, suppliers, lenders, and commercial accounts. Data is largely self-reported by creditors — there is no federal requirement that trade creditors report to business bureaus, so not all credit relationships are captured. Business credit reports are not subject to the FCRA — anyone can pull a business credit report on any business, and there are fewer dispute rights than with personal credit.
For most small businesses — especially those under $5 million in revenue — both personal and business credit are evaluated by lenders. Personal credit typically carries more weight because it has a longer, more complete history and legal protections that make the data more reliable. Business credit scores become more important as businesses grow, establish longer track records, and begin to access credit in the business entity's name rather than through personal guarantees.
The FICO Small Business Scoring Service (SBSS) is a composite credit score specifically designed for small business lending. Unlike D&B Paydex or Experian Intelliscore, the FICO SBSS is not a pure business credit score — it is a blended score that combines personal credit information (the owner's personal FICO) with business credit data and financial information about the business into a single predictive score.
Score range: 0 to 300, with higher scores indicating lower credit risk. Unlike personal FICO where scores cluster in a relatively narrow range, FICO SBSS scores are more evenly distributed across the range.
Why it matters for SBA: The SBA requires lenders using SBA Express and SBA 7(a) streamlined processing to calculate the borrower's FICO SBSS score as part of the application. Applications below the minimum threshold (currently 155 for most programs) require more manual underwriting and are less likely to receive favorable SBA processing. Applications with SBSS scores above 160 to 165 typically qualify for the SBA's streamlined processing, which significantly reduces documentation requirements and processing time.
What goes into the FICO SBSS: The score incorporates personal credit history of the business owner(s), the business's age and financial characteristics, payment history on existing business obligations, industry risk factors, and public records associated with the business and its principals. Because it is a composite model, improving the FICO SBSS requires improvement in both personal credit and business credit profiles simultaneously.
Where it is used: Primarily by SBA-approved lenders for SBA Express and 7(a) processing. Some non-SBA commercial lenders also use the FICO SBSS as a component of their underwriting models, but it is most critical in the SBA context. If SBA financing is on your radar — for a commercial real estate purchase, a major equipment acquisition, or a business acquisition — your FICO SBSS score is worth checking and improving before you apply.
The D&B Paydex score is the most widely recognized pure business credit score in the United States. It is used by trade creditors, suppliers, vendors, and commercial lenders to assess a business's payment reliability on commercial obligations.
Score range: 1 to 100. The score represents the weighted average payment speed on all commercial obligations reported to D&B within the past 12 months.
Score interpretation: A Paydex of exactly 80 means the business pays its obligations, on average, exactly on the due date (neither early nor late). Scores above 80 indicate that payment is made, on average, ahead of terms. Scores below 80 indicate average late payment — the further below 80, the more days late on average. Dun & Bradstreet publishes the following equivalency: 100 = 30 days early; 90 = within terms; 80 = on time; 70 = 15 days late; 60 = 22 days late; 50 = 30 days late; lower scores indicate increasingly severe delinquency.
What goes into Paydex: Paydex is calculated entirely from trade payment experiences reported to D&B by creditors — suppliers, vendors, and commercial lenders who report payment data. A business with zero reported trade lines has no Paydex score, which is functionally the same as a poor score for many trade creditors. Personal credit does not factor into Paydex — it is purely a business payment history measure.
How to access your Paydex: Businesses can check their D&B Paydex score and file through Dun & Bradstreet's CreditSignal or Dun & Bradstreet Credit product lines. A D-U-N-S number (a nine-digit identifier D&B assigns to each business entity) must be established before a Paydex score can be generated. DUNS numbers are free to obtain at D&B's website.
Experian Business's primary small business credit score is the Intelliscore Plus (also written as Intelliscore℠). It is the closest analog to a personal FICO score in the business credit world — a statistical model that predicts the probability of a business becoming severely delinquent within the next 12 months.
Score range: 1 to 100. Lower scores indicate higher risk; higher scores indicate lower risk. Experian segments the range into risk categories: 76–100 is Low Risk; 51–75 is Low-Medium Risk; 26–50 is Medium Risk; 11–25 is High-Medium Risk; 1–10 is High Risk.
What goes into Intelliscore Plus: Experian's model incorporates business payment history on commercial accounts, public records (liens, judgments, bankruptcies filed against the business), industry risk, business age and size, the owner's personal credit profile, and the business's credit utilization on existing commercial accounts. The model heavily weights recent payment behavior — the most recent 12 months of payment history are the primary driver of the score. Negative items in the personal credit profile of the principal owner also affect the score, unlike pure Paydex which does not incorporate personal credit.
Where Intelliscore Plus is used: Experian Intelliscore is commonly used by commercial lenders, insurance companies (for business insurance underwriting), and commercial vendors when evaluating a business for credit. Banks, alternative lenders, and fintech platforms that pull business credit typically pull Experian Business data as part of their underwriting, though their models may incorporate other factors beyond the Intelliscore number itself.
Equifax Business: Equifax also maintains a business credit scoring product (Equifax Business Failure Score and related scores), though it is less commonly referenced in small business discussions than D&B Paydex or Experian Intelliscore. Lenders who pull Equifax Business credit do so as part of comprehensive business credit assessment, particularly for larger loan amounts or more sophisticated commercial credit analysis.

Credit scores only matter in the context of what outcomes they produce. Here is how different score combinations translate into real lending access for small businesses:
Personal FICO 720+, FICO SBSS 165+, D&B Paydex 80+, Experian 76+. Access to SBA 7(a) and 504 streamlined processing. Conventional bank lines of credit and term loans. Equipment financing at low rates. Alternative lenders compete aggressively for this profile. Unsecured business loans at lowest rates in the market. Best chance of approval without needing collateral.
Personal FICO 680–720, FICO SBSS 155–165, D&B Paydex 70–79, Experian 51–75. SBA loan eligibility with standard underwriting (more documentation required than streamlined). Bank term loans and lines at standard pricing. Equipment financing readily available. Alternative lenders offer good terms. A few products are more expensive than for the strong profile, but this borrower can access essentially the full market.
Personal FICO 620–680, FICO SBSS below 155, D&B Paydex 60–69, Experian 26–50. SBA financing is difficult — most SBA streamlined declines; manual underwriting required with strong compensating factors. Bank unsecured products largely inaccessible. Conventional commercial mortgages require substantial down payments. Alternative lenders (MCA, short-term loans, revenue-based) are accessible. Rates are higher than for strong profiles but the market is open.
One important nuance: for most alternative lenders — MCA providers, fintech working capital lenders, revenue-based financing platforms — business credit scores are far less important than personal FICO and bank statement revenue. These lenders have built underwriting models around cash flow data rather than credit bureau data. A business with a mediocre D&B Paydex and a strong personal credit score and $100,000/month in revenue will typically get approved for alternative products at reasonable rates even without an established business credit file.
Conversely, for bank lending and SBA programs — where business credit scores carry more weight — a strong D&B Paydex and FICO SBSS genuinely expand access and improve pricing. The payoff from building business credit is most meaningful for businesses that plan to grow and access institutional financing over time.
Building business credit requires deliberate action. It does not happen automatically just because you operate a business. Here is the step-by-step process for establishing a meaningful business credit profile:
Business credit improvement timelines are meaningfully faster than personal credit in some respects — and much slower in others. Here is a realistic expectation-setting guide:
Fast improvements (1–3 months): Adding new reporting trade lines with D&B-reporting vendors and paying early. Three to five net-30 accounts paid ahead of terms can move a Paydex from zero (no file) to 80 within 90 days. Correcting factual errors in business credit reports — wrong address, wrong SIC code, duplicate entries — can improve scores within 30 days of successful dispute resolution.
Medium-term improvements (3–12 months): Consistent on-time or early payment across multiple trade lines building a track record. Adding a business credit card with favorable payment history. The FICO SBSS responds to improvement in personal FICO over this time frame as well. Experian Intelliscore improvements from reduced utilization and improved payment patterns typically take 3 to 6 months to reflect meaningfully in scores.
Long-term improvements (1–3 years): Major negative items (collections, judgments, tax liens) typically require the full passage of time before their impact fades. Business age itself improves scores over time — a 3-year-old business is a materially better credit risk in most models than a 1-year-old business, all else equal. Building relationships with multiple commercial trade creditors who consistently report positive payment history creates a deep credit profile that takes years to establish.
The personal credit connection: For FICO SBSS and Experian Intelliscore, personal credit improvement is a lever for business credit improvement. Paying down personal credit card balances, maintaining on-time personal payments, and avoiding new hard inquiries all contribute to personal FICO improvement that flows into FICO SBSS.

FAQ
Personal credit reflects individual borrowing history (SSN-based); business credit reflects the business entity's payment history on commercial obligations (EIN-based). They are maintained by different bureaus and scored differently. For most small businesses, both are evaluated by lenders, with personal credit typically carrying more weight. Business credit scores become more important as businesses grow and access institutional financing.
FICO SBSS (0–300) is a composite score combining personal and business credit data, used by SBA lenders to screen applications. Scores of 155+ typically qualify for SBA streamlined processing; 165+ is preferred. Below 155, applications require more manual underwriting. If SBA financing is on your radar, checking and improving your FICO SBSS before applying is important preparation.
The D&B Paydex (1–100) measures payment timing — 80 means exactly on time. Above 80 means early payment; below 80 means average late payment. For commercial lending and trade credit, 75+ is generally acceptable; 80+ is good; scores above 80 (indicating early payment habit) are ideal. Below 70 suggests payment problems that warrant investigation by lenders and vendors.
Building a meaningful D&B Paydex score can happen within 90 days by establishing reporting trade lines and paying early. A useful FICO SBSS requires both personal credit improvement and business track record — typically 1 to 2 years minimum. Full business credit profiles that are competitive for institutional lending take 2 to 3 years of consistent positive payment history across multiple trade lines.
Not directly. Business and personal credit are separate systems. Activity on business credit accounts does not automatically appear on personal reports unless you personally guaranteed the obligation. Some business credit cards do report to personal bureaus — check card terms before applying. Personal guarantees on business loans may appear on personal credit reports and can affect personal scores.
The fastest path: add net-30 trade accounts with D&B-reporting vendors and pay every obligation early (not just on time). Paying early above 80 Paydex provides a buffer against occasional late payments. Correcting errors in business credit reports can also produce fast score improvements. For FICO SBSS, improving personal FICO is the parallel task — since personal credit is a major SBSS input.
