How to Build Business Credit
The 7-step process to build business credit from scratch — EIN, entity, tradelines, funding. The Wealth Lab framework, condensed.
§ 01
What is business credit?
Business credit is the credit file attached to your legal entity — separate from you, separate from your SSN, separate from your personal credit score. A strong business file lets your company borrow, buy, and scale without you personally guaranteeing every dollar.
The three bureaus that matter: Dun & Bradstreet (PAYDEX score), Experian Business, and Equifax Business. Each maintains an independent file. None of them auto-populate the way personal credit does — you have to build every one by hand.
Done right, business credit becomes a moat: cash flow you can access without dilution, capital that scales with revenue, and separation between you and the business when things get bumpy.

How to build business credit — step by step
Step 01
Form the entity properly
LLC or corp with a real business address (not your home if you can avoid it), a dedicated business bank account, and a business phone number. Lenders check all three before they approve a dollar.
Do this → File the entity, open the bank account, get a business phone line the same week.
Step 02
Get your EIN and D-U-N-S number
The EIN from the IRS is free and instant. The D-U-N-S from Dun & Bradstreet is what commercial lenders actually pull to check your business credit file.
Do this → IRS.gov for EIN. DNB.com for the free D-U-N-S — never pay for it.
Step 03
Register with the three business bureaus
Dun & Bradstreet (PAYDEX), Experian Business, and Equifax Business. Your business has three credit files, not one — and none of them auto-populate like personal credit.
Do this → Verify your business is listed with all three. Correct the record if it isn't.
Step 04
Open Tier 1 vendor tradelines
Net-30 accounts with vendors that report to the business bureaus — Uline, Grainger, Quill, Crown Office Supplies. Small purchases, paid early, reported to the bureaus. This is the foundation.
Do this → Open 5 net-30 accounts. Buy something small. Pay before the due date.
Step 05
Layer Tier 2 store credit
Once you have 5 reported tradelines and a PAYDEX score, apply for store credit — Amazon Business, Home Depot, Lowe's, Staples. These raise your available credit fast.
Do this → Apply for 3 store cards. Use them modestly. Pay statements in full.
Step 06
Move to Tier 3 cash credit and fleet cards
Fleet cards (WEX, Fuelman) and cash credit lines from banks that lend on business credit — not personal PGs. This is where the real capital lives.
Do this → Target one fleet card and one bank line at the 6-month mark.
Step 07
Access funding without personal guarantees
Once your business file is thick — 8+ tradelines, PAYDEX 80+, 6+ months seasoned — you qualify for real business funding: SBA, revenue-based lending, business lines of credit with no PG.
Do this → At month 9-12, apply for a $25K+ business line of credit. Don't PG unless you have to.
§ 03 · FAQ
Common questions about business credit
How long does it take to build business credit?+
Six months for a workable file, 12 months to qualify for real capital without personal guarantees. Anyone promising faster is either lying or selling shortcuts that damage the file long-term.
Can I build business credit with bad personal credit?+
Yes. Business credit and personal credit are separate systems. The catch: most Tier 1 vendors don't check personal credit at all, but Tier 3 lenders often do. Fix both in parallel.
Do I need an LLC to build business credit?+
You need a real legal entity — LLC, S-Corp, or C-Corp. A sole proprietorship uses your SSN, which means every account reports to your personal credit. That defeats the point.
What's the fastest way to build business credit?+
The fastest legitimate path: file the entity, get an EIN and D-U-N-S the same week, open 5 net-30 vendors in month one, and pay every invoice 10 days early. Consistency beats hacks.
What is a PAYDEX score?+
PAYDEX is Dun & Bradstreet's business credit score, 0-100. 80 or higher means you pay on time or early. Most commercial lenders want to see 80+ before they extend meaningful credit.
