The Business Credit Playbook

Why business credit even matters

Most owners fund everything on a personal credit card or personal loan — which caps how much they can borrow, puts their personal score at risk every time the business has a slow month, and keeps every lender asking for a personal guarantee forever. Business credit breaks that link. Built right, it lets your business borrow on its own track record, not yours.

Step 1 — Make the business a real, separate entity

• Form an LLC or corporation in your state — sole props don't build business credit, period.
• Get an EIN (free, instant, at irs.gov) — this is the business's "social security number."
• Open a dedicated business bank account using the EIN, not your SSN. Never mix personal and business spending from this point forward.
• Get a business phone number and listed address — lenders and data bureaus verify these before extending anything.

Step 2 — Get a D-U-N-S number and register with the bureaus

Dun & Bradstreet assigns your business a D-U-N-S number (free, dnb.com) — this is what most vendor and lender credit checks pull. Business credit has its own three bureaus: Dun & Bradstreet (PAYDEX score), Experian Business, and Equifax Business. None of them auto-populate — you build the file by using credit and having it reported.

Step 3 — Open net-30 vendor trade lines first

Vendor accounts are the fastest way to start a credit file, because most approve based on the business, not a personal credit pull. You buy something, get 30 days to pay, and if the vendor reports to the bureaus, that payment becomes your first trade line.

• Start with 3–5 vendors that report to D&B (Uline, Quill, Grainger are commonly cited starter accounts — verify current reporting status before applying).
• Buy something you'd purchase anyway — office supplies, packaging, tools.
• Pay early, every time. On-time is good; early is what pushes your PAYDEX score toward 80+.

Step 4 — Layer in business credit cards

After 3–5 reporting trade lines (usually 60–90 days in), apply for a business credit card. Early on, most issuers still check your personal credit — that's normal. As your business file matures, you'll qualify for cards that weigh the business file more heavily and eventually ones that don't require a personal guarantee at all.

Step 5 — Know the timeline

• Month 1–2: entity, EIN, bank account, D-U-N-S, first vendor accounts.
• Month 3–4: 3–5 trade lines reporting, first business credit card.
• Month 6–12: established PAYDEX/business score, access to higher vendor limits and better card terms.
• Year 1+: qualify for business lines of credit and term loans based primarily on the business file.

The five mistakes that stall people

• Mixing personal and business spending after the account is open.
• Applying for too much credit at once and triggering hard pulls across multiple bureaus.
• Picking vendors that don't actually report to D&B/Experian/Equifax — no reporting, no credit file, no matter how much you spend.
• Paying on time instead of early — PAYDEX specifically rewards early payment, not just on-time.
• Never checking the file — pull your D&B, Experian Business, and Equifax Business reports at least twice a year and dispute errors immediately.
