Business Credit Scores Explained: How to Build and Improve Yours
Your business has a credit score, whether or not you have ever checked it. Lenders, suppliers, landlords and even customers can look it up, and most small business owners have no idea what it says. This explainer covers how business credit scores work, who calculates them and a step-by-step plan to build a strong one from nothing.
Key takeaways
- Business credit is separate from your personal credit, tied to your company's identifiers rather than your Social Security number.
- The main US scores are Dun and Bradstreet's PAYDEX, Experian Intelliscore Plus, Equifax Business and FICO SBSS. Each uses a different scale.
- Payment history dominates. Paying suppliers early, not just on time, is the fastest way to raise a PAYDEX score.
- Unlike personal credit, business credit reports are not free by law and anyone can buy yours, so check it before a lender does.
When you apply for a business loan, lease a storefront, open a trade account with a supplier or bid on a large contract, someone may pull your business credit report. If the file is empty, you are a risk. If it shows late payments, you are a bigger one. If it shows years of early payments to a mix of suppliers and lenders, you get better terms and faster approvals.
The frustrating part is that business credit does not build itself. Many of the payments you make every month are never reported to the business credit bureaus, so a company can have a spotless record and still an empty file. Building a score is a deliberate project, and this guide shows how to run it.
Business credit versus personal credit
Personal credit in the US is tied to your Social Security number and governed by the Fair Credit Reporting Act, which gives you the right to free reports and limits who can see them. Business credit is tied to your company's Employer Identification Number and its name and address. There is no legal right to a free business credit report, and the reports are essentially public: a supplier, a competitor or a journalist can buy one.
The two are not fully separate in practice. Most small business lenders and card issuers check the owner's personal credit as well, and most require a personal guarantee. The FICO SBSS score, used by the US Small Business Administration and many banks, blends business and personal data. But a strong business file reduces how much your personal history matters and, over time, lets the company borrow on its own standing.
Common mistake
Assuming that paying business bills on time automatically builds business credit. Most utility companies, landlords, software vendors and small suppliers do not report to business bureaus. If none of your creditors report, your file stays empty no matter how reliable you are. You have to use accounts that report, or ask your suppliers to become trade references.
The main business credit scores
| Score | Scale | What it emphasizes | Commonly used by |
|---|---|---|---|
| Dun and Bradstreet PAYDEX | 1 to 100 | Whether you pay suppliers within terms; 80 means on time, above 80 means early | Suppliers, landlords, government contracting |
| Experian Intelliscore Plus | 1 to 100 | Payment history, credit utilization, public records, company age and industry risk | Lenders and card issuers |
| Equifax Business | Several scores including a payment index (0 to 100) and credit risk scores | Payment behavior, delinquency and failure risk | Lenders and insurers |
| FICO SBSS | 0 to 300 | A blend of business and personal credit data from multiple bureaus | SBA 7(a) lenders and many banks |
Each bureau draws on different data, so your scores will not match each other. The SBA has used a minimum FICO SBSS score as a screening step for its smaller 7(a) loans; the cutoff has changed over time, so check the current figure if you plan to apply.
What goes into a business credit score
- Payment history. The dominant factor. Bureaus track not just whether you paid but how many days before or after the due date.
- Credit utilization. How much of your available credit lines you are using. Lower is better, as with personal credit.
- Public records. Liens, judgments, bankruptcies and UCC filings against the business.
- Company age and size. Older businesses with more employees and revenue score better, all else equal.
- Industry risk. Some bureaus adjust for the failure rate of your industry.
- Number and mix of accounts. Several reporting trade lines and a loan or card look stronger than a single account.
How to build business credit from scratch
- Form a legal entity and get an EIN. An LLC or corporation with its own Employer Identification Number separates the business from you in the eyes of the bureaus. A sole proprietorship can have a business file, but it is harder to keep apart from your personal record.
- Make the business look consistent everywhere. Use the exact same legal name, address and phone number on your formation documents, bank account, website, licenses and supplier applications. Bureaus match records by these details, and mismatches split your file or lose data.
- Open a business bank account. Lenders look for a track record of business banking, and some bureaus use bank data. Run every business transaction through it.
- Get a D-U-N-S number. Dun and Bradstreet's identifier is free to request and required for a PAYDEX score and for many government and large-company supplier programs.
- Open trade accounts with suppliers that report. Office supply, shipping, fuel and industrial suppliers often offer net-30 terms to new businesses and report payments to one or more bureaus. Ask directly: "Do you report payment history to Dun and Bradstreet, Experian or Equifax?" Aim for three to five reporting accounts.
- Get a business credit card. Choose an issuer that reports to business bureaus. Use it for regular expenses and pay the statement in full.
- Pay early, not just on time. PAYDEX rewards paying before the due date. Paying net-30 invoices within 10 to 15 days is the single most effective habit for that score.
- Keep utilization low. Stay well under 30% of available limits on cards and lines, and ask for limit increases as the business grows.
- Monitor the file. Check your reports at least twice a year. Dispute errors, add missing trade references and watch for accounts you do not recognize.
Worked example
Imagine a new landscaping LLC. In month one the owner gets an EIN, opens a business checking account and requests a D-U-N-S number. In month two she opens net-30 accounts with an office supply company, a fuel card program and an equipment parts supplier, all of which confirm they report. She buys $300 to $500 a month on each and pays within ten days. In month four she adds a business credit card with a $5,000 limit and keeps the balance below $1,000. By month nine, with three trade lines and one card reporting consistently early payments, she has a PAYDEX score above 80 and a thin but positive Experian file. When she applies for a $25,000 equipment loan in month twelve, the lender sees a business with a track record instead of a blank page.
Pro tip
Suppliers you already pay reliably but who do not report can sometimes be added as trade references on your Dun and Bradstreet file. It costs you a phone call and a form, and it turns years of invisible good behavior into score-building data.
How to improve a weak or damaged score
If the file already shows late payments, the path is the same as personal credit repair, with a shorter memory. Business bureaus typically weight recent behavior heavily, and many trade data points age off within a few years.
- Bring every account current and keep it there. A run of twelve clean months changes the picture dramatically.
- Pay down revolving balances to lower utilization quickly.
- Resolve public records. Pay off tax liens and judgments and make sure the release is recorded.
- Dispute inaccuracies with each bureau in writing. Mixed files, where another company's data lands on yours, are common when names are similar.
- Add positive accounts. New reporting trade lines dilute old negatives.
- Avoid closing old accounts in good standing; they add age and available credit.
Helps your score
- Paying net-30 invoices within 10 to 15 days
- Several reporting accounts with low balances
- Consistent business name, address and phone across all records
Hurts your score
- Payments even a few days past terms
- Maxed-out cards and lines
- Unresolved liens, judgments or collections
Outside the United States
Business credit reporting exists in most developed economies but works differently. In the UK, agencies such as Experian, Equifax and Creditsafe score limited companies using filed accounts at Companies House, payment data and county court judgments; filing accounts on time matters as much as paying on time. In Canada, Equifax and Dun and Bradstreet operate business files much as in the US. In many other countries, bank-run credit registries dominate and supplier payment data is less widely reported. The principles still hold: use credit that gets reported, pay early, keep your public filings clean and check your file. Confirm the specifics with your local agencies.
Business credit action plan
- Confirm your legal entity, EIN and a consistent business name, address and phone
- Open a dedicated business bank account
- Request a D-U-N-S number
- Open three to five net-30 trade accounts with suppliers that report
- Add a business credit card that reports to business bureaus
- Set payment reminders to pay invoices within 10 to 15 days
- Pull your business reports twice a year and dispute errors
Frequently asked questions
How long does it take to build a business credit score?
With several reporting accounts paid early, a PAYDEX score can appear within a few months, since Dun and Bradstreet needs a minimum number of reported payment experiences. A file strong enough for bank lending without heavy reliance on personal credit usually takes one to two years of consistent history.
Does checking my business credit hurt the score?
No. Checking your own report has no effect. Lender inquiries can appear on the file, but they carry far less weight than in personal credit scoring.
Will a business credit card affect my personal credit?
It depends on the issuer. Some report all activity to personal bureaus, some report only if the account defaults, and some never report to personal bureaus. Nearly all require a personal guarantee, so a default will affect you regardless. Ask before applying.
Can I build business credit as a sole proprietor?
Yes, with an EIN and a D-U-N-S number, but the file is harder to keep separate from your personal record and lenders will lean on your personal score. Forming an LLC or corporation makes the separation cleaner.

The bottom line
A business credit score is built, not earned by default. Set up the entity and identifiers, use accounts that actually report, pay suppliers early, keep balances low and check the file regularly. Do that for a year and your company will have a credit history that opens doors on its own strength. Scoring models, cutoffs and bureau practices change over time and differ by country, so verify current details with the agencies and lenders you deal with.
