How to Build Business Credit: A Step-by-Step Guide
You’ve been in business for a year. Sales are steady. Then a supplier asks for trade references, or a lender asks about your business credit history, and you realize your company doesn’t have one yet. Everything has been running through your personal cards and your personal name.
Business credit doesn’t build itself. It starts when your business has its own legal identity and accounts that report to the business credit bureaus. This guide walks through how to set that up, what the bureaus track, and how long it usually takes..
TL;DR
- Business credit is a separate record from your personal credit, tracked mainly by Dun & Bradstreet, Experian, and Equifax.
- To build it, form an LLC or corporation, get an EIN and a D-U-N-S number, and open a business bank account.
- Then open accounts that report to the business bureaus, such as net-30 vendor accounts and a business credit card, and pay them on time or early.
- Check your business credit reports with each bureau, since they often hold different information.
- Expect it to take several months before you have a score, and longer before it’s strong. Lenders may still review your personal credit.
What is business credit, and how is it different from personal credit?
Business credit is the credit history of your company, tied to its legal name and Employer Identification Number (EIN) instead of your Social Security number. Business credit bureaus build it from what lenders, suppliers, and public records report about how your business pays its bills. Lenders, suppliers, and insurers may check it before extending terms.
If you operate as a sole proprietor, the SBA notes there is no legal or financial separation between you and your business, so credit activity is tied to you as an individual. Forming an LLC, LLP, or corporation is what allows your business to have a credit file of its own.
| Personal credit | Business credit | |
| Tied to | Your Social Security number | Your business’s legal name and EIN |
| Main bureaus | Equifax, Experian, TransUnion | Dun & Bradstreet, Experian, Equifax |
| Common score ranges | 300–850 (FICO® Score) | Varies by bureau, often 1–100 (see below) |
| How it starts | Automatically, when you open credit in your name | Only when accounts in the business’s name report to a business bureau |
| Who can see it | Only those with a permissible purpose under federal law | Generally available to anyone who buys the report |
| Free reports | Yes, through AnnualCreditReport.com | No federal free-report right; some bureaus offer limited free views |
The two records are separate, but they aren’t always independent. Lenders may review both, especially when a business is young. A personal guarantee can also make you personally responsible for a business debt. For more on the personal side, see How to Improve Your Credit Before Applying for a Small Business Loan.
Who tracks business credit, and what do the scores mean?
Three bureaus maintain most U.S. business credit files: Dun & Bradstreet, Experian, and Equifax. Each uses its own scores and scales, and a lender may check one, two, or all three. FICO also produces a business score that blends business and owner data. Higher is better on every scale below.
| Bureau and score | Range | What it measures | Generally seen as strong |
| Dun & Bradstreet PAYDEX® | 1–100 | How promptly the business has paid reported bills over the past 12–24 months | 80 means paid within terms; above 80 means paid early |
| Experian Intelliscore Plus℠ | 1–100 (V1 and V2); 300–850 (V3) | Risk of serious delinquency over the next 12 months | 76–100 is Experian’s lowest-risk class on the 1–100 scale |
| Equifax Business Credit Risk Score | 101–992 | Likelihood of severe delinquency | Higher scores mean lower risk |
| Equifax Payment Index | 0–100 | Payment history with creditors and vendors | 90 or more indicates bills paid on time |
| Equifax Business Failure Score | 1,000–1,880 | Likelihood the business closes within 12 months | Higher scores mean lower risk |
| FICO® Small Business Scoring Service (SBSS) | 0–300 | Blended business and owner credit data | Set by each lender |
One recent change: as of March 1, 2026, the SBA no longer requires the FICO SBSS score to prescreen 7(a) Small Loans. Lenders may still use it in their own reviews. For how lenders weigh these scores, see How Your Business Credit Score Affects Loan Approval.
How do you build business credit from scratch?
To build business credit, give your business its own legal and financial identity, then open accounts in the business’s name that report payments to the business credit bureaus. Paying those accounts on time, or early, is what creates and strengthens your scores. Here are the seven steps.
1. Form a business entity. Register your business as an LLC, LLP, or corporation with your state. This makes it a legal entity separate from you, which is what allows it to hold its own credit file. Talk with an attorney or accountant about which structure fits your situation.
2. Get an EIN. An Employer Identification Number is your business’s federal tax ID. You can apply for free on the IRS website. You’ll use it to open bank accounts, file taxes, and apply for credit. Be wary of sites that charge a fee for an EIN; the IRS doesn’t.
3. Make your business details consistent everywhere. Use the same legal business name, address, and phone number on your state registration, IRS records, bank accounts, and credit applications. Mismatched details can split your history across files or make it hard for a bureau to match payments to your business.
4. Open a business bank account. A dedicated account keeps business and personal money separate. It also gives lenders a clear record of your deposits and balances, and it can serve as a bank reference on credit applications.
5. Get a D-U-N-S® Number. Dun & Bradstreet uses this nine-digit number to identify your business and connect it to a credit file. Requesting one is free; D&B charges only if you want faster processing. Check first whether your business already has one, since D&B sometimes creates files on its own.
6. Open accounts that report to the business bureaus. This is the step that actually starts your credit history. Common starting points:
- Net-30 vendor accounts. Suppliers that let you pay invoices within 30 days and report those payments to a bureau. Ask each vendor which bureaus it reports to before you rely on it.
- A business credit card. Many issuers report business card activity to the business bureaus. See the next section for what to check first.
- A small business loan or line of credit. Responsible repayment can add to your history, if the lender reports it.
The SBA notes that once several trade lines are reporting, a business credit score is generated. D&B generally needs multiple payment experiences from more than one reporting company before it calculates a PAYDEX score.
7. Pay on time, or early, and monitor your reports. On-time payment is the core of every business score. On the PAYDEX scale, paying on the due date earns about an 80, and paying early is what moves a score higher. Check your files with D&B, Experian, and Equifax at least a few times a year, since each may hold different information. Correct an outdated address or a payment recorded as late by contacting the bureau and the company that reported it.
Does a business credit card build business credit?
It can, but only if the issuer reports to the business bureaus, and reporting practices vary. Most major issuers report business card activity to the commercial bureaus. Many don’t say which ones, so ask before you apply.
Three things to check first:
- Where it reports. Some issuers report only to the business bureaus. Others also report ongoing activity, or only late payments, to your personal credit reports.
- The personal guarantee. Most small business cards require one. That means you remain personally responsible for the balance if the business can’t pay, even when the card doesn’t appear on your personal reports.
- Your personal credit. Issuers typically review the owner’s personal credit when approving a newer business.
Used well, a business card also makes bookkeeping easier. Keeping all business purchases on one business account gives you a cleaner record at tax time and avoids mixing personal and business spending.
What mistakes slow down business credit building?
The most common setbacks come from accounts that don’t report, details that don’t match, and payments that slip during a busy stretch.
Never checking your files. Errors are common, and you can’t fix what you haven’t seen.
Assuming every account reports. Paying a vendor on time builds nothing if that vendor doesn’t report to a bureau.
Mixing personal and business spending. It muddies your records and weakens the separation you’re trying to build.
Inconsistent business information. A different address or name format on one application can create a duplicate or incomplete file.
Letting payments slide. A single late payment can lower payment-based scores like PAYDEX quickly, and lower scores take time to rebuild.
Paying for shortcuts. Paying a service won’t remove accurate negative information from your file. Be cautious of companies that promise instant business credit or a guaranteed score.
How long does it take to build business credit?
There’s no fixed timeline. A score generally appears only after several accounts have reported payments, which often takes a few months once those accounts are open. Building a strong, established profile usually takes longer, because the length of your history and a consistent payment record both matter. Starting early, before you need financing, gives your business the most room.
Frequently asked questions about building business credit
Does an LLC automatically have business credit? No. Forming an LLC makes business credit possible, but a credit file builds only when accounts in the business’s name report to a business bureau.
Can I build business credit with an EIN only? You can start building a business credit file using your EIN. Many lenders and card issuers will still review your personal credit and may ask for a personal guarantee, especially for a newer business.
Do I need a D-U-N-S Number to build business credit? You need one to have a Dun & Bradstreet file and a PAYDEX score. Experian and Equifax can build files without it. Getting a D-U-N-S Number is free.
Can I check my business credit for free? There is no federal right to a free business credit report the way there is for personal reports. Some bureaus offer limited free views, such as score ranges or alerts. Full reports usually cost money.
Does my personal credit affect my business credit score? It can. Some business scores, such as FICO SBSS and blended Experian scores, consider the owner’s personal credit. Lenders may also review personal credit separately.
The bottom line
Business credit starts with structure: a separate entity, an EIN, a D-U-N-S Number, and a business bank account. It grows through accounts that report and payments made on time or early. Start before you need financing, check your files with all three bureaus, and keep business and personal finances apart.
