Business Credit Score
Also known as: commercial credit score, business creditworthiness, business credit rating
Definition
Business credit scores measure a business's creditworthiness separately from the owner's personal credit — the three major bureaus are Dun & Bradstreet (PAYDEX), Experian Business (Intelliscore Plus), and Equifax Business (Business Credit Risk Score) — and they matter for loan approvals, vendor terms, and insurance rates.
Detailed explanation
Business credit scores exist to evaluate the creditworthiness of a business entity independent of its owners' personal finances. This separation is important because: (1) personal credit limits (FICO) of 850 cap potential risk differentiation; (2) business credit files capture trade-credit relationships that personal credit never reflects; (3) separating business and personal credit protects the owner from business credit events affecting personal credit and vice versa.
The three major business credit bureaus operate differently from personal credit: D&B's PAYDEX (0-100, payment timing), Experian Business's Intelliscore Plus (1-100, delinquency prediction), and Equifax Business Credit Risk Score (101-992 for the risk score; 0-300 for the payment index). Each has different data contributors — a vendor might report only to D&B, another only to Experian. Monitoring all three is necessary for a complete picture.
Building business credit is a deliberate process: (1) incorporate the business and get an EIN, (2) open a business bank account in the business name, (3) get a D&B DUNS number, (4) establish trade lines with suppliers that report to business bureaus, (5) get a business credit card, (6) pay everything on time. Unlike personal credit, there are no automatic or passive ways to build business credit — it requires intentional steps.
◈ Worked example
- A 3-year-old LLC with 5 trade lines all paid on time: D&B PAYDEX 80 / Experian Intelliscore 78 / Equifax Business Credit Risk Score 620. Combined profile = strong; qualifies for net-30 terms from most suppliers without deposits.
- A 1-year-old sole proprietorship with no trade lines: no PAYDEX (insufficient history), Intelliscore may be in medium range drawing on personal credit blend. Lender must rely on personal FICO and bank statements.
- Business credit score benefit: suppliers that check D&B may require 0% deposit for net-30 accounts from an 80 PAYDEX business; same supplier requires 50% deposit from a business with no D&B history.
Common questions
The most-asked questions about Business Credit Score — answered straightforwardly.
Does a business credit score affect my personal credit? +
Generally no, provided you've properly separated business and personal finances (EIN, business bank account, business credit cards used only for business). Business credit events (delinquencies, liens) typically stay on business credit files. However, personal guarantees on business loans may appear on personal credit when the loan is originated, and if you personally guarantee and default, the collection can appear on your personal credit.
How long does it take to build a business credit score? +
With deliberate action: 6-12 months to establish a meaningful score across all three bureaus. First 30-90 days: get EIN, DUNS, business bank account. Days 30-120: establish 3-5 trade lines with D&B-reporting vendors. Month 6+: consistent on-time payments produce visible PAYDEX and Intelliscore. SBA-quality business credit scores (strong enough to influence underwriting) typically take 2-3 years of consistent history.
Do lenders check business credit or personal credit for small business loans? +
Most lenders check both. Personal credit (FICO) is checked for owner(s) providing personal guarantees. Business credit (D&B, Experian Business, Equifax Business) is checked to evaluate the business entity's credit history. SBA loans require personal FICO 650+ for most programs. Strong business credit with weaker personal credit may still qualify for some alternative lenders that emphasize business performance.
