Building Business Credit.

Business credit is its own thing

Your personal credit follows your Social Security number. Business credit follows your company — its EIN, its legal name, its payment history. Building it gives you real advantages:

• Higher limits. Business cards and lines routinely run $25,000–$100,000+, far above typical personal cards.
• Better vendor terms. Suppliers extend net-30 / net-60 instead of demanding cash up front.
• Less personal exposure. Over time, a strong business profile reduces how often you have to personally guarantee the debt — so the company's risk stays with the company.
• Lower costs. Even commercial insurers and landlords check business credit when setting premiums and approving leases.

The D-U-N-S number (yes, it still matters)

The D-U-N-S number is a free, 9-digit ID from Dun & Bradstreet — the backbone of your business credit file. You can't have a D&B credit score without one.

Get it free directly from D&B (the free route can take up to ~30 days). They sell a paid expedite (~$229) but you rarely need it — apply the day you set up the business and the wait runs in the background.

Know who's scoring you

Personal credit settled on one familiar 300–850 scale. Business credit never did — there are several scores on different scales, and a lender may pull more than one:

• Dun & Bradstreet — PAYDEX (0–100). The most cited. It's purely about payment timing: paying exactly on terms gets you 80 (the "good" line most lenders want); paying early is how you climb toward 100.
• Experian Business — Intelliscore Plus (1–100). A broader risk score. Generates automatically once trade lines report — no signup needed.
• Equifax Business — Business Risk Score + Payment Index. Also auto-generated as activity reports.
• FICO SBSS (0–300). The one that surprises people: it blends your business credit with your personal credit, and the SBA and banks use it to screen loan applications (often a 7(a) cutoff around 155+).

The build sequence

Order matters — skip a step and the later ones stall. The path:

• 1. Separate legal entity. An LLC or corporation, so the business is its own "person," apart from you. (If you already run an LLC, this is done.)
• 2. EIN. Free from the IRS — the business's tax ID.
• 3. Business bank account in the exact legal name. Run everything through it; never mix personal and business money.
• 4. Business address & phone that are listed and searchable — bureaus and lenders look for a real, findable business.
• 5. D-U-N-S number (free from D&B).
• 6. Open net-30 vendor accounts that report — the engine, explained below.
• 7. Let it season, then graduate to store/fleet cards and business credit cards.

Net-30 tradelines — where the score is built

A tradeline is any account that reports your payment behavior to a business bureau. Net-30 vendors let you buy now and pay within 30 days — and the ones that report turn those payments into your credit history. How to do it right:

• Open 3–5 accounts with vendors that report (common starters: Uline, Quill, Grainger). Most card issuers want to see at least 3 reporting tradelines before approving you, so fewer than 3 stalls the build.
• Buy something real from each — genuinely useful supplies, not junk.
• Pay early — within about 10 days, not at day 30. PAYDEX rewards early payment, not just on-time. This is how you beat 80.
• Confirm they report. Ask directly: "Do you report payments to Dun & Bradstreet, Experian Business, or Equifax Business?" A vendor that doesn't report does nothing for your credit, no matter how useful otherwise. This is the #1 reason a "built" profile shows no score.

The personal-guarantee reality

Don't believe anyone promising you instant "no personal guarantee" funding. The truth: early on, most real business cards (Chase Ink, Amex, Capital One Spark) still require a personal guarantee — meaning you're on the hook if the business can't pay. True no-PG products exist (Brex, Ramp), but they approve based on your revenue and bank balances, not credit history, so a brand-new business with little revenue rarely qualifies. Building business credit doesn't erase personal exposure overnight — it reduces it over time as the company proves itself. That's the honest arc.

What tanks business credit

• Liens, judgments & tax liens. D&B pulls public records — an unresolved lien or judgment can sink your fundability no matter how good your PAYDEX is.
• High utilization. Maxing out business cards signals risk even when you pay on time.
• Mixing personal and business money. It blurs the file and undercuts the whole point of separation.
• Paying vendors that don't report. Effort with zero credit reward — always verify reporting first.
• Watching only one bureau. Different lenders pull different scores; monitor all three so you catch errors and missing tradelines.

Timeline — and the scams to skip

Done right, a business becomes scorable in about 60–90 days and genuinely fundable in 6–12 months. That's the real pace. Anyone selling "business credit overnight," "shelf corporations," or ways to borrow big with no history and no guarantee is selling a problem, not a shortcut — those schemes can cross into fraud and wreck both your business and personal standing. The boring path — entity, DUNS, reporting tradelines, pay early, monitor — is the one that actually works.

The whole build, start to finish

Set up the entity → free EIN → business bank account in the exact name → searchable address & phone → free D-U-N-S number → open 3–5 reporting net-30 tradelines and pay early → let 3 cycles season for a PAYDEX → graduate to cards → keep utilization low, avoid liens, monitor all three bureaus. Run that play patiently and your business stops leaning on your personal credit and starts standing on its own.
