Your business credit score directly affects the interest rates you’re offered, the loan amounts you qualify for, and whether you get approved at all. Yet most business owners don’t even know their business credit score exists, let alone how to improve it. Taking steps to improve your business credit score is one of the highest-return investments you can make — better credit translates directly into cheaper, more accessible financing.
Understanding Business Credit Scores
Business credit scores are separate from personal credit scores and are maintained by three major bureaus: Dun & Bradstreet (PAYDEX score, 0 to 100), Experian Business (Intelliscore, 0 to 100), and Equifax Business (Business Delinquency Score, 101 to 670). Unlike personal scores that range from 300 to 850, each bureau uses its own scale.
The PAYDEX score from Dun & Bradstreet is the most widely used. A score of 80+ is considered excellent and indicates you pay vendors on time or early. Scores below 50 signal significant payment problems.
7 Steps to Build and Improve Your Score
1. Get a DUNS Number
Your Dun & Bradstreet number is the foundation of your business credit profile. If you don’t have one, apply for free at the D&B website. Without a DUNS number, you essentially don’t exist in the business credit world.
2. Pay Every Bill Early
The PAYDEX score is almost entirely based on payment history relative to terms. Paying 30 days early earns the highest marks. Paying on time is good, and paying late — even by a few days — tanks your score. Set up autopay for every vendor account.
3. Open Trade Lines with Reporting Vendors
Not all suppliers report to business credit bureaus. Specifically seek out vendors and suppliers that do report — these are called trade references. Office supply companies, shipping services, and some credit card issuers commonly report. The more positive trade lines on your file, the stronger your profile.
4. Get a Business Credit Card
A secured or unsecured business credit card that reports to business bureaus is one of the fastest ways to improve your business credit score. Keep utilization below 30 percent and pay the full balance monthly.
5. Monitor and Dispute Errors
Pull your business credit reports regularly and dispute any inaccuracies. Late payments that were actually on time, accounts that don’t belong to you, and incorrect balances can all drag your score down.
6. Keep Business and Personal Finances Separate
Use a dedicated business bank account and business credit card for all business expenses. Commingling funds creates confusion and can hurt both personal and business credit.
7. Build Gradually with Small Credit
Start with small vendor accounts and credit lines, use them responsibly, and build up over time. A history of consistent, responsible borrowing is more valuable than a single large credit line.
How Long Does It Take?
Business credit can be established from scratch in 3 to 6 months if you’re strategic. Improving an existing poor score takes 6 to 12 months of consistent positive behavior. The PAYDEX score updates as new payment data is reported, so improvements can appear relatively quickly compared to personal credit.
The key is consistency. One missed payment can undo months of progress, while steady on-time (or early) payments build a strong score over time.
Frequently Asked Questions
Q: Is a business credit score the same as a personal credit score?
A: No. They’re completely separate scores maintained by different bureaus. Your business score reflects the company’s payment history and creditworthiness.
Q: Can I check my business credit score for free?
A: Nav.com offers free access to basic business credit information. Full detailed reports typically require a paid subscription from D&B, Experian, or Equifax.
Q: Does my personal credit affect my business credit?
A: Not directly, but many lenders check both. A strong personal score can help during early stages when your business credit history is thin.
