Business Credit & Personal Credit: The Complete Guide

Why credit matters more than income

You can earn good money and still get denied. Lenders don't just ask "can you pay?" They ask "have you proven you will?" Your credit report is that proof.

For founders, credit decides whether you can get equipment financing, a line of credit, a business card, a lease or a loan when an opportunity shows up. It also affects the rates you pay, which can add up to thousands of dollars.

Strong credit gives you options. Options give you leverage.

How personal credit works

Your FICO score uses five main factors. Knowing them tells you exactly where to focus:

• Payment history (about 35%) — paying on time, every time. One late payment can hurt for years.
• Amounts owed / utilization (about 30%) — how much of your available credit you're using. Lower is better.
• Length of history (about 15%) — older accounts help. Think twice before closing your oldest card.
• Credit mix (about 10%) — a blend of cards and loans can help slightly.
• New credit (about 10%) — lots of recent applications can lower your score.

How business credit works

Business credit is tracked by separate bureaus — mainly Dun & Bradstreet, Experian Business and Equifax Business. The scores look different too. Dun & Bradstreet's PAYDEX, for example, runs from 1 to 100 and focuses heavily on whether you pay vendors on time or early.

To have business credit at all, your company needs to look like a real, separate entity:

• Form a legal entity — usually an LLC or corporation.
• Get an EIN — free from the IRS.
• Open a business bank account — keep business and personal money separate.
• Use a consistent business name, address and phone everywhere.
• Get a D-U-N-S number — free from Dun & Bradstreet.
• Open vendor accounts that report — and pay them early.

Personal vs business credit: the key differences

• Identifier — personal uses your SSN; business uses your EIN and D-U-N-S number.
• Who can see it — personal reports are protected; business reports can generally be bought by vendors and lenders.
• Scoring — personal scores run roughly 300–850; business scores use different scales.
• Liability — personal guarantees put your own credit on the line for business debt.
• Why both matter — young businesses usually lean on the owner's personal credit until the company has its own track record.

A 90-day credit plan for founders

Days 1–30: Know and clean

Pull your free reports at AnnualCreditReport.com. Check every account, balance and late payment. Dispute anything inaccurate with the bureau that reports it. Set up autopay for at least the minimum on everything.

Days 31–60: Lower utilization

Pay balances down, ideally under 30% of each limit and lower overall. Pay before the statement date so lower balances get reported.

Days 61–90: Build the business profile

Complete your entity setup, bank account and D-U-N-S number. Open one or two vendor accounts that report, and pay early.

Mistakes that cost founders the most

• Mixing personal and business spending — it muddies your records and weakens your business profile.
• Maxing cards for inventory — high utilization drags your score down right when you need it.
• Closing old accounts — it shortens your history and raises utilization.
• Applying everywhere at once — multiple hard inquiries signal risk.
• Ignoring your reports — errors are common, and you can't fix what you don't check.
