Business Credit Score: What Lenders See

What is a business credit score?

A business credit score is a number that a credit bureau calculates from a company's payment records, public filings and firm data to estimate how likely it is to pay on time. A lender may pull this file next to your personal credit report.

Each bureau runs its own model, so one company can carry several scores on different scales. Much of the data comes from suppliers and public filings, not from the owner.

This guide covers which scores exist, how to check them and what to fix before you apply. Building a credit history from zero is a separate topic.

Which business credit scores do lenders see?

Lenders can see business credit scores from Dun & Bradstreet, Experian and FICO. Each one answers a slightly different question about the same company. PAYDEX looks back at how you paid, while the D&B Delinquency Predictor Score and Failure Score look ahead.

Sources: Dun & Bradstreet pages on PAYDEX and scores and ratings, Experian and FICO, as of November 8, 2026.

FICO SBSS is built for lenders. FICO describes it as a service for lenders that pulls data from major consumer and commercial sources. We do not quote an SBSS range, because we have no primary source for one.

Equifax keeps business files too, and owners reach them through a reseller, covered in the section on how to check your score.

The same number on two scales does not mean the same thing, because each bureau uses its own model and its own data. Read every score against its own scale.

How is a business credit score different from a personal score?

A business credit score rates the company, while a personal score rates you as a borrower. The two run on different scales and follow different rules on who can see them.

Visibility comes first. Per Experian, a business credit score is public, unlike a personal one. Potential lenders, partners or even competitors can check a company's profile at any time.

The scales are the second difference. The Federal Reserve groups both kinds of score into the same risk bands:

Source: Fed Small Business Credit Survey, 2026 Report on Employer Firms, credit risk definitions. These bands are as defined in the Fed Small Business Credit Survey, so they are survey definitions, not lender rules.

Business scores also appear in public loan programs. Per SBA SOP 50 10 8.1, effective October 1, 2026, an SBA Express lender may use a business credit scoring model. Under the same SOP, that model cannot rely solely on consumer credit scores, and it may only be used in addition to the lender's own credit analysis.

Worked example: how dollar weighting reads three supplier payments

Dollar weighting means a large invoice counts for more than a small one. In this Commera illustrative calculation, a business paid only one of three invoices on time, yet 80% of its invoice dollars were paid on terms.

Methodology: Illustrative calculation with three hypothetical supplier invoices. It shows the dollar-weighted principle in the Dun & Bradstreet PAYDEX definition. It is not the PAYDEX formula, does not predict a score and does not describe a real business.

Count the invoices, and the record looks weak, because two of three bills were late. Weight them by dollars, and the picture changes.

The large packaging bill paid on terms carries most of the weight. Now reverse the case in this illustrative calculation: if the $8,000 bill were the late one, that single invoice would outweigh both small bills paid on time.

This example does not convert into score points. It shows one thing only: in a dollar-weighted record, the bills with the largest amounts matter most.

How to check your business credit score

To check your business credit score, go to each bureau separately, because each one keeps its own file and offers its own route.

Dun & Bradstreet. Per Dun & Bradstreet, D&B Credit Insights has a Free plan at $0/mo. The Free tier leaves out the Maximum Credit Recommendation and the D&B Rating.

Experian. You can search for your company and buy its business credit report on the Experian site.

Equifax. Per Equifax, owners order its small business report and relevant scores from eCredable, an approved Equifax reseller.

Once you have the reports, read them line by line.

Example: file check before you apply

1. Business name and address match. Compare the name and address in each file with your bank account and tax records.
2. Trade lines reported. Look for your main suppliers in the payment section. A supplier that does not report its payments adds nothing to the record.
3. Open liens. Look for liens still marked open after you settled them, and note the filing date of each one.
4. Public records. Read the public records section for filings that belong to a different company with a similar name.
5. Score reason or risk class. Note the reasons listed next to each score or risk class, since they point to what to fix first.

Worked example: what a lower rate is worth on a $60,000 loan

A lower rate on the same loan cuts both the payment and the total cost. In this Commera illustrative calculation, the lower of two assumed rates saves $86.34 a month and $3,108.05 over the term.

Methodology: Illustrative calculation, not an offer and not a real deal: one business takes one term loan with 36 level monthly payments at two assumed rates, 14.00% and 11.00%. A 2% fee of $1,200 is withheld from the proceeds. The estimated APR is the internal rate of return of the payments against the amount received. Rates are assumptions, not a table of scores and rates.

Rate is not APR. The fee pushes the estimated APR above the stated rate in both columns, because the business pays interest on the full loan but receives less cash.

The table does not say that a given score earns a given rate. Lenders price the whole file. Every figure here is subject to underwriting. Total repayment uses the unrounded monthly payment.

What should you fix before you apply?

Fix errors in the company file first, then make sure the payments you make are reported. Both steps take time. Start before a lender pulls the file.

Experian disputes. Per Experian, you can dispute an item with the Submit Data Dispute button at the bottom of your report, or email the report with a short note. Experian says an investigation is generally completed within 30 days, though complex cases may take longer. If changes are made, Experian provides a second complimentary report so you can confirm them.

Dun & Bradstreet updates. Per Dun & Bradstreet, you can review, request updates to or dispute basic information in your D&B file for free, including your payment history. Submissions are subject to verification.

Unreported payments. Per the Dun & Bradstreet PAYDEX page, payment experiences that go unreported cannot be considered in its scores. Ask your regular suppliers whether they report to D&B, and if not, ask them to start.

If you plan to request a business line of credit, give corrections time to show up first. Our guide on how to get a business loan covers the documents lenders ask for next.

When the file is clean, check your funding options to see which products fit your profile.
