Building business credit is not complicated. But it is sequential. The difference between entrepreneurs who reach a fundable 700+ FICO-equivalent business profile in 90 days and those who spin their wheels for years is almost always this: they understood the vendor tier system before they started. This page is the hub for everything FiStarr covers on business credit vendors — NET-30 accounts, fuel cards, no personal guarantee credit, and startup funding — organized by credit tier and bureau coverage so you can execute a real strategy, not just open random accounts.
The core principle: Business credit bureaus — Dun & Bradstreet, Experian Business, and Equifax Business — build your score from tradeline payment history. Vendor accounts are the tradelines. The right vendors, applied to in the right order, paying on the right schedule, create a fundable business credit profile. Everything else is detail.
Who This Guide Is For
This guide is for business owners who have already formed a legal entity (LLC or corporation), obtained an EIN from the IRS, registered for a DUNS number, and are ready to begin building an actual business credit file. If you have not completed those steps, start with the EIN-only business credit guide and the DUNS number guide first.
The Three Business Credit Bureau Files You Need Open
Unlike personal credit — which flows through three bureaus automatically — business credit files must be actively opened. Before applying to any vendor account, confirm these three files are active:
- Dun & Bradstreet (D&B) — generates your Paydex score, the most commonly checked business credit score by lenders. Requires a DUNS number and at least 3 tradelines reporting within the last 12 months to produce a score.
- Experian Business — generates your Intelliscore Plus (0–100). Many bank lenders and corporate card issuers pull this alongside D&B.
- Equifax Business — generates the Business Credit Risk Score. Home Depot, Lowe's, and several Tier 2 vendors report here exclusively or in addition to D&B.
The Four-Tier Business Credit Vendor Framework
Not all vendor accounts are created equal. Applying to Tier 2 vendors before you have Tier 1 tradelines reporting is the most common reason new business owners get denied. The tier system maps the approval prerequisites at each stage.
| Tier | Prerequisite | Primary Goal | Examples |
|---|---|---|---|
| Tier 1 | New entity, DUNS only | Activate D&B file, open bureau tradelines | Crown Office, Uline, Summa, Ordertrend |
| Tier 2 | 3-5 Tier 1 tradelines, 90+ days | Expand bureau coverage, raise limits | Grainger, Office Depot, Amazon Business |
| Tier 3 | Paydex 70+, 6+ tradelines, 6+ months | Business credit cards, fuel cards | Shell Business, Sam's Club, Home Depot |
| Tier 4 | Paydex 80+, revenue history or cash | No-PG cards, LOC, funding | Brex, Ramp, Fundbox, Bluevine |
Entity Setup: The Prerequisites Every Vendor Checks
Vendor approval systems check your business profile against public databases before pulling any credit. The most common denial reason for new entities is inconsistency between registrations. Before applying anywhere, confirm all of the following match exactly — same spelling, same abbreviations, same address format — across your state filing, IRS EIN letter, D&B file, Google Business Profile, and business bank account:
- Legal business name (exactly as registered with your state)
- Business address (physical address preferred; a UPS or Regus address can work but must be consistent)
- Business phone number (a dedicated business line, not your personal cell)
- SIC or NAICS industry code (assigned at D&B registration — affects which vendors will approve you)
- Business email domain (yourname@yourbusiness.com, not Gmail)
- Business bank account with 90+ days of history
