Why business credit is different from personal credit

Personal credit and business credit are entirely separate systems. A perfect personal credit score does not automatically create business credit. You have to build the business profile deliberately — it doesn't accrue on its own.

Business credit is what lenders, vendors, and suppliers look at when you apply for a business line of credit, net-30 vendor accounts, or commercial financing. Operators who skip building it find out at the worst possible moment: when they need capital and have nothing to show.

The three major business credit bureaus are Dun & Bradstreet (Paydex score), Experian Business, and Equifax Business. Lenders may check one or all three. Your job is to build a positive history across all of them.

⏱️
Start now regardless of whether you need funding

The most common mistake: waiting until you need a loan to start building business credit. By then you're 12–18 months behind. The second-best time to start was last year. The best time is today.

The 12-month build sequence

Business credit builds in layers. Each one takes time — you can't compress the timeline by applying for more things faster. Work through these in order.

1
Form a legal business entity
Business credit requires a business. Sole proprietors operating under their personal name have limited ability to separate business credit from personal credit. An LLC is the minimum — it costs $50–$500 depending on state and takes 1–2 weeks. S-Corp if you're already profitable at significant revenue.
2
Get an EIN from the IRS
Your Employer Identification Number is your business's tax ID — the equivalent of a Social Security Number for your business. Apply free at IRS.gov. Takes 5 minutes. Required before opening a business bank account or applying for most business credit.
3
Open a business bank account
Business banking history is one of the primary inputs lenders use to evaluate creditworthiness. Six months of consistent, positive banking activity with no overdrafts is the minimum most lenders want to see. Mercury and Relay are both free and built for solo operators. See the banking hub →
4
Register with Nav and get a D-U-N-S number
Nav pulls your business credit profile from all three bureaus and shows you exactly what lenders see. Free tier is enough to start. A D-U-N-S number (from Dun & Bradstreet) is required before most business credit can be reported — register free at dnb.com. Both take 10 minutes and should be done the same week you open your bank account.
5
Apply for a starter business credit card
A business card that reports to business credit bureaus is your primary credit-building tool. Capital One Spark reports reliably. Chase Ink Cash is excellent if you qualify. Pay the full balance every month — on-time payment is the single most important factor in your Paydex score. See the cards hub →
6
Establish net-30 vendor accounts
Net-30 accounts let you purchase and pay 30 days later — and many report payment history to business credit bureaus. Quill, Uline, and Grainger are the classic starter accounts. Apply, make a small purchase, pay early, repeat. Three to five active net-30 accounts reporting positive history significantly accelerates your Paydex score.
7
Monitor and maintain for 12 months
Check your Nav dashboard monthly. Dispute any errors. Keep your business address and phone consistent across all registrations (IRS, state, D&B, bank). Pay every account early or on time. After 12 months of clean history, you have the foundation for a business line of credit.

Four mistakes that slow down business credit

1
Applying for credit before banking history exists
Lenders want to see 6+ months of consistent business banking. Applying for a business line of credit with 2 months of banking history almost always gets rejected — and the hard inquiry stays on your report. Build the foundation first.
2
Inconsistent business address and contact information
Business credit bureaus use your address and phone to match accounts to your business profile. If your IRS registration, state filing, D&B profile, and bank account show different addresses, accounts don't link correctly and your profile stays thin. Use one consistent address everywhere.
3
Not monitoring for errors
Business credit report errors are common and can significantly damage your score. Check Nav monthly. Dispute anything inaccurate directly with the bureau. Errors don't fix themselves.
4
Carrying balances on business cards
Business credit utilization (balance vs. limit) affects your score. Carrying a balance month-to-month signals financial stress to lenders. Pay in full every month — it's the single most controllable factor in your business credit score.

Realistic timeline

Month 1: Form LLC, get EIN, open business bank account, register with Nav, get D-U-N-S number.

Month 2: Apply for starter business credit card. Apply for 2–3 net-30 vendor accounts (Quill, Uline).

Months 3–6: Pay everything on time or early. Make regular business purchases through your business card. Keep banking account positive and active.

Month 6: Check Nav — you should have a D&B Paydex score of 80+ if you've been paying early. Experian and Equifax business profiles should be establishing.

Month 12: Apply for a business line of credit through Lendio or a similar marketplace. You now have the banking history, the credit profile, and the track record lenders need.
