What Are Business Credit Bureaus?

Business credit bureaus are agencies that collect, analyze, and sell credit information about businesses. They track how your company pays its bills, how much credit it uses, and how long it's been in operation. Lenders, vendors, and suppliers use this data to decide whether to extend credit to your business.

Unlike personal credit bureaus (Equifax, Experian, TransUnion), which are heavily regulated by the Fair Credit Reporting Act, business credit bureaus operate with fewer restrictions. This means:

The Three Major Business Credit Bureaus

1. Dun & Bradstreet (D&B)

Dun & Bradstreet is the oldest and most widely used business credit bureau, founded in 1841. They maintain credit files on over 400 million businesses worldwide.

Which Bureau Matters Most?

It depends on who you're applying with:

Lender / Vendor TypeBureau They Usually Check
Net-30 vendors (Uline, Quill, Grainger)Dun & Bradstreet
Chase business credit cardsExperian Business + D&B
American Express business cardsExperian Business
Capital One business cardsExperian Business + personal credit
Business lines of creditAll three + personal credit
SBA loansAll three + personal credit + FICO SBSS

Bottom line: Build all three bureaus, but prioritize D&B first (vendors report there most consistently) and Experian second (credit card issuers check it heavily).

How to Monitor All Three Bureaus

Unlike personal credit, there's no free annual report for business credit. Monitoring options include:

ServiceBureaus CoveredCost
D&B CreditMonitorD&B only$39–$149/month
Experian Business Credit AdvantageExperian only$39–$189/month
Equifax Business Credit MonitorEquifax only$99–$199/year
Nav Business Credit BuilderD&B + Experian$29–$49/month

For most e-commerce sellers, Nav offers the best value because it covers the two most important bureaus at a reasonable price.

How to Dispute Errors on Business Credit Reports

Business credit disputes are harder than personal credit disputes because there's no FCRA equivalent. Here's the process:

  1. Pull your report: Buy a copy directly from the bureau
  2. Identify the error: Note the specific account, amount, and date
  3. Gather evidence: Collect payment receipts, bank statements, or vendor correspondence
  4. File a dispute: Each bureau has an online dispute portal or email address
  5. Follow up: Bureaus have 30 days to investigate, but business disputes often take longer
  6. Escalate if needed: Contact the creditor directly and ask them to correct the reporting

Frequently Asked Questions

Do all Net-30 vendors report to all three bureaus?

No. Most report only to Dun & Bradstreet. Uline and Summa report to D&B and Experian. Very few report to Equifax. Always verify reporting before applying.

Can I build business credit without paying for monitoring?

Partially. D&B offers a free basic report. Experian and Equifax charge for full reports. Nav offers a free tier with limited data. For serious credit building, budget $30–$50/month for monitoring.

Why is my business credit score different across bureaus?

Because each bureau uses different data sources, scoring models, and weighting factors. D&B focuses on payment speed. Experian weighs utilization and inquiries. Equifax emphasizes public records. It's normal to have a 20–30 point spread.
