Why business credit matters
Business credit is a separate scoring system from your personal FICO. The major business credit bureaus — Dun & Bradstreet (D-U-N-S number / Paydex), Experian Business (Intelliscore), and Equifax Business — track payment history on business obligations.
Strong business credit lets you qualify for trade credit with vendors, larger loan amounts, lower rates, and eventually financing that doesn't require a personal guarantee. Building it deliberately is one of the highest-ROI things a business owner can do.
Foundation steps
Before you can build business credit, your business needs to exist as a separate entity:
- Form an LLC or corporation (sole proprietors have no separate business credit)
- Obtain an EIN from the IRS (free at irs.gov)
- Open a business bank account in the entity's name
- Register for a D-U-N-S number with Dun & Bradstreet (free)
- Register your business address and phone number consistently across all filings
- Get a business credit card in the business name
Get your first reporting tradelines
A tradeline is a business account that reports payment activity to one of the business credit bureaus. The challenge: most vendors don't report. You need to actively seek out ones that do.
Vendors known for reporting (verify current reporting status):
- Office supply vendors (Quill, Uline)
- Fleet fuel cards (WEX, Fuelman)
- Business credit cards from major issuers (Capital One Spark, Chase Ink, Amex Business)
- Some net-30 supplier accounts (Grainger, Crown Office Supplies)
- Business utility accounts (in business name)
Aim for 3–5 reporting tradelines in your first year. Open them, use them for small purchases, and pay early. 'Early' (5+ days before due date) reports better than 'on time' to D&B's Paydex score.
The Paydex score
D&B's Paydex score ranges from 0 to 100 and is calculated based on how early or late you pay.
- 100: Paying 30+ days before due date
- 90: Paying 20+ days before due date
- 80: Paying on the due date (this is the 'good' threshold)
- 70: Paying 15 days late
- Below 70: Significant late payments — limits future credit access
Most lenders want to see 80+. Reaching that requires intentional 'pay early, every time' behavior — not just 'don't pay late.'
Common mistakes to avoid
- Using personal credit for business expenses. Every personal-card business purchase is a missed opportunity to build business tradelines.
- Inconsistent business information. Different addresses, phone numbers, or business names across filings hurts your D&B profile.
- Closing old tradelines. Length of credit history matters; closing old accounts shortens it.
- Maxing out business credit cards. Utilization affects business credit just like personal. Keep balances under 30% of limits.
- Ignoring business credit reports. Pull your reports annually and dispute errors. Mistakes are common.
Timeline to expect
Building meaningful business credit typically takes 12–24 months of consistent, deliberate activity. Year 1: establish 3–5 reporting tradelines, build initial Paydex above 80. Year 2: qualify for larger trade lines, your first business loan without (or with reduced) personal guarantee.
There are no shortcuts. Services advertising 'instant business credit' are usually selling course content, not credit lines.
Frequently Asked Questions
How long does it take to build business credit?
Most businesses need 12–24 months of consistent reporting activity to build meaningful business credit. The first reporting tradeline can show up in 30–60 days, but a usable score takes a year of deliberate work.
Do business loans build business credit?
Only if the lender reports to business credit bureaus. Many alternative lenders don't report. Ask before signing. Banks, SBA-backed loans, and most business credit cards do report.
Is business credit separate from personal credit?
Yes — different bureaus, different scoring systems, different identifiers (EIN vs SSN). But many small-business products still pull both, and personal guarantees tie your personal credit to business obligations.
