How to Improve Business Credit Score: A Step-by-Step Guide

Business Credit vs. Personal Credit

Business credit is a separate credit profile for your company — distinct from your personal credit score. Lenders use it to assess risk when you apply for business loans, lines of credit, vendor terms, and business credit cards.

Three agencies track business credit: **Dun & Bradstreet** (Paydex score, 0–100), **Experian Business** (Intelliscore, 0–100), and **Equifax Business** (Business Credit Risk Score, 101–992). Unlike personal credit, businesses start with NO credit history — it must be actively built.

Step 1: Establish Your Business Entity

Before building credit, your business needs a proper legal identity:

• **Incorporate or form an LLC** — sole proprietors can't build separate business credit
• **Get an EIN** (Employer Identification Number) from the IRS — free at irs.gov
• **Open a business bank account** — never mix personal and business finances
• **Get a business phone number** listed in directory assistance
• **Register with D&B** — get a free D-U-N-S Number at dnb.com (takes 30 days)
• **Establish a business address** — a P.O. box works; avoid using your home address

Step 2: Build Trade Lines

Trade lines are vendor accounts that report payment history to business credit bureaus. These are the fastest way to build a Paydex score:

Tier 1 (No Credit Check): Net-30 accounts that don't check credit — Uline, Quill, Grainger. Order supplies, pay on time, and they report to D&B.

Tier 2 (Business Credit Cards): Secured business cards or cards from issuers who report to business bureaus — Brex, Ramp, Capital One Spark, American Express Business.

Tier 3 (Bank Lines): Once you have 5+ trade lines, apply for a business line of credit from your bank.

Step 3: Pay Early, Not Just On Time

The Paydex score rewards **early payment** — not just on-time payment. A score of 80 means on-time. A score of 90+ means you pay before the due date.

Set up automatic payments for all business accounts. Early payment of even $1 over what's due signals strong financial health to lenders. Never let any trade line go 30 days past due — one late payment can drop your Paydex by 15–20 points.
