Business Credit Basics: How to Build It From $0

Most founders confuse business credit with their personal credit score. They're related, but they're not the same — and the difference matters more than you'd think. Here's the no-jargon walkthrough.

What business credit actually is

Business credit is a separate credit profile attached to your EIN (not your SSN). The three main bureaus are Dun & Bradstreet, Experian Business, and Equifax Business. They track:

• Payment history with vendors and lenders.
• Outstanding business debt.
• Public records (liens, judgments, bankruptcies).
• Time in business.

A strong business credit profile lets you:

• Qualify for higher credit lines without a personal guarantee.
• Get better rates on commercial loans.
• Set up Net-30/60/90 payment terms with suppliers.
• Lease equipment without putting your house on the line.

The prerequisites (do these first)

Before you can build business credit, you need:

1. Form an LLC or Corp — sole props can't build separate business credit.
2. Get an EIN.
3. Open a business bank account in the business's name.
4. Get a business phone number — even a Google Voice line counts.
5. Register with Dun & Bradstreet — request a free D-U-N-S number.
6. Match your business name and address everywhere — Secretary of State, IRS, bank, D&B. Discrepancies kill applications.

The 5-step build

Step 1: Open 3–5 Net-30 vendor accounts

These are the easiest first tradelines. Companies like Uline, Quill, Grainger, and Crown Office Supplies report to business bureaus when you pay on time. Order something you'd actually use, pay early, repeat.

Step 2: Open a starter business credit card

Cards that don't require strong business credit and do report to business bureaus include some Capital One Spark cards and certain Amex options. Use it lightly (under 30% utilization) and pay in full monthly.

Step 3: Add 1–2 store cards

Office Depot, Lowe's Business, and Home Depot Pro often issue store cards based on your DUNS profile. They build depth without much risk.

Step 4: After 6–12 months, apply for a true business credit card

Once you have 5+ tradelines reporting and a Paydex score above 80, apply for a "real" business card — Chase Ink, Amex Business Gold, etc. Many will still ask for a personal guarantee at this stage, which is normal.

Step 5: Move to credit lines and term loans

Once business credit is established, you can apply for unsecured business lines of credit and term loans without a personal guarantee — typically requiring 2+ years in business and consistent revenue.

Common mistakes to avoid

• Mixing personal and business spending. Kills your liability shield and your credit-building progress.
• Paying late even once. Business credit penalizes lateness more harshly than personal credit.
• Closing your oldest tradeline. Length of history matters here too.
• Maxing out cards "to build credit faster." Utilization above 30% will tank scores.
• Ignoring D&B mailers. Sometimes they upsell you on a "CreditBuilder" subscription you don't need — but the free DUNS request is essential.

A realistic timeline

• Months 1–3: Foundation set up. First Net-30s open.
• Months 3–6: First Paydex score appears. Add starter business card.
• Months 6–12: Score climbs above 80. Add store cards.
• Year 2: Eligible for unsecured business credit cards.
• Year 2–3: Eligible for unsecured lines of credit and SBA loans.

When business credit actually matters

For most founders, business credit becomes important when you:

• Want to scale inventory without your personal cash.
• Need equipment or vehicles.
• Want a commercial lease.
• Plan to sell or finance the business in the future.

If you're a service-based solo founder with no inventory and no plans to scale beyond your time, business credit is "nice to have." For everyone else, it's leverage you'll be glad you built.
