Most new business owners are confused by the same thing: their personal FICO is 740, their revenue is $400K a year, and they get rejected for a $25K business line. How does that happen?
Because business lenders read two reports, and the one you probably haven't seen matters more than the one you have.
The two systems, side by side
Personal credit is scored by FICO (300–850 scale) or VantageScore. It's built from your credit cards, auto loans, mortgage, and other personal borrowing. The three big bureaus — Experian, Equifax, TransUnion — all keep a file on you. You see this score on Credit Karma, in your banking app, on your credit card statement.
Business credit is scored by Dun & Bradstreet (PAYDEX, 0–100), Experian Business (Intelliscore, 0–100), and Equifax Business (0–100). It's built from your business's trade accounts, business credit cards, business loans, and payment behavior with vendors. Most owners have never seen their business score and have no idea what it is.
Which lender cares about which
- Short-term working capital / MCA: mostly ignore personal and business credit, care about bank statements and revenue. Approve down to 500 personal FICO.
- Business lines of credit (fintech): personal FICO is primary (680+ typical), business credit used if available.
- SBA 7(a) loans: personal FICO 680+ required, business credit and tax returns examined in detail.
- Traditional bank business loans: both reports pulled, business credit weighed heavily on larger lines ($100K+).
- Business credit cards: personal FICO drives approval. Business credit develops after.
- Net-30 vendor accounts: business credit only.
Why they pull personal even for business loans
For most small businesses, the owner is the business. If you have no business credit history yet — and 65% of businesses under 5 years old don't — the lender has nothing to score except you personally. Your personal FICO is the proxy for "is this human a credit risk."
The other reason: personal guarantee. Almost every small business loan under $500K requires one. If the business can't pay, you pay. So the lender insists on a credit check of the actual human on the hook.
Building business credit from zero
You can't "apply" for a business credit score. You build one through accounts that report. The fastest route:
- File for a DUNS number at dnb.com. Free. This is your business's social security number for credit purposes.
- Open 3 net-30 vendor accounts that report to business credit bureaus: Uline, Grainger, Quill, Nav's tradeline service. Buy routine supplies. Pay early.
- Open one business credit card: Chase Ink Business Unlimited is the industry entry. Uses your personal FICO to approve, then starts reporting to business credit.
- Wait 6 months. By month 6, you have a PAYDEX score. Pay everything on time or early and you're over 80 inside a year.
A PAYDEX of 80+ plus a personal FICO of 700+ unlocks the vast majority of small business credit decisions.
The one mistake that kills both
Running business expenses on personal credit cards and maxing them out. This hurts your personal utilization (which is a huge FICO factor) and gives you no business credit to show for it. If you're going to carry a balance for the business, do it on a business card — the utilization sits on the business file, not yours.
What to do today
Pull both. Personal: annualcreditreport.com (free, all three bureaus). Business: Nav.com has a free business credit snapshot. If you're going to apply for anything bigger than $25K in the next 12 months, start today — building business credit from zero to a usable score takes 6–9 months of boring consistent payments.
