How Business Credit Works: Building Credit for Your Company

Business credit is one of the most powerful and underutilized tools available to entrepreneurs. Unlike personal credit, business credit is tied to your company's EIN — not your Social Security Number. Done right, it lets you access tens of thousands of dollars in capital without a personal guarantee, and at far better terms than most personal credit products.

This guide explains how business credit works from the ground up and gives you a clear roadmap to build it.

Business Credit vs. Personal Credit: Key Differences

• Identifier: Personal credit uses your SSN; business credit uses your EIN
• Credit bureaus: Personal credit: Equifax, Experian, TransUnion. Business credit: Dun & Bradstreet, Equifax Business, Experian Business
• Public access: Business credit is often publicly accessible — vendors and banks can check it
• Score range: Personal FICO scores go 300-850. Business scores vary by bureau (D&B Paydex: 0-100, Experian Business: 0-100)
• Personal guarantee: With strong business credit, you can get financing without personally guaranteeing the debt
• Separation: Business credit protects your personal credit score from business liabilities

Business Credit Bureaus: Who Tracks Your Score

Dun & Bradstreet (D&B) — The Most Important

D&B maintains the DUNS Number system, which is the global standard for business identification. Their primary credit score is the Paydex Score (0-100), which measures how promptly you pay your bills:

• 80-100: Low risk (ideal)
• 50-79: Moderate risk
• 0-49: High risk

Experian Business

Experian tracks business payment history and provides the Intelliscore Plus score (0-100). Many lenders and credit card companies pull Experian Business when evaluating applications.

Equifax Business

Equifax provides the Business Payment Index (0-100) and other risk scores used by lenders, suppliers, and insurers.

How to Build Business Credit: Step by Step

Step 1: Establish Your Business Foundation (Before Any Credit)

Before you can build credit, your business must be set up properly:

• Form your LLC and receive your Articles of Organization
• Obtain your EIN from the IRS
• Open a dedicated business bank account
• Get a business phone number (even a Google Voice number works)
• Create a professional business email and website
• Register your business address (virtual mailbox services work for non-residents)

Step 2: Get Your DUNS Number (Free)

Register with Dun & Bradstreet to get a DUNS Number — your unique business identifier in the D&B system. This is free and takes about 30 days to activate your file. Without a DUNS Number, vendors and lenders can't find your business credit history.

Step 3: Open Vendor/Trade Credit Lines

Trade credit is credit extended by suppliers who let you buy now and pay later (net 30, net 60 terms). The key is to open accounts with vendors that report to business credit bureaus. This is how you build payment history.

Starter vendors that report to D&B and often approve new businesses:

• Uline — packaging and shipping supplies (net 30)
• Quill.com — office supplies (net 30)
• Grainger — industrial supplies (net 30)
• Summa Office Supplies — net 30 starter accounts

The strategy: Open 3-5 vendor accounts, make small purchases, pay within the net terms (or early), and let them report your positive payment history.

Step 4: Build 3-6 Months of Payment History

After 3-6 months of on-time or early payments with trade vendors, your business credit profile begins to build momentum. A Paydex score of 80+ is achievable within 6 months with consistent on-time payments.

Step 5: Apply for a Business Credit Card

With a solid business bank account and some payment history, you can apply for business credit cards. Start with cards that are easier to obtain:

• Capital One Spark Cash — good for established businesses
• American Express Blue Business Cash — reports to business bureaus
• Bill.com Divvy — corporate card based on bank balance

Step 6: Apply for Business Lines of Credit

With 6-12 months of positive business credit history, you can begin applying for business lines of credit from banks, CDFIs, and alternative lenders.

Key Rules for Maintaining Strong Business Credit

• Pay early: Business credit rewards early payment. Paying 10+ days before the due date often results in the highest possible scores
• Keep utilization low: Don't max out credit cards or lines of credit. Stay below 30% of your limit
• Diversify: Mix trade credit, credit cards, and loans for a stronger profile
• Monitor regularly: Check your business credit reports for errors
• Never mix personal and business: All business expenses go on business accounts

How Long Does Building Business Credit Take?

• Month 1-2: Foundation setup (LLC, EIN, bank account, DUNS)
• Month 3-6: Trade vendor accounts established, payment history building
• Month 6-12: Business credit cards, initial credit profile
• Month 12-24: Business lines of credit, larger financing opportunities
• Month 24+: Access to significant business financing without personal guarantee

Business credit building requires patience and consistency. The entrepreneurs who stick to the process and make on-time payments for 1-2 years gain access to capital and opportunities that most businesses never achieve.
