Getting a Business Credit Card and Building Business Credit

A business credit card is usually the first revolving credit line a new company can actually qualify for, and it is the on-ramp to a real business credit profile. Done right, it separates your company's finances from your personal finances, builds a payment history under your business's name, and eventually lets you borrow at better terms without putting your personal credit on the line. Done wrong, it just becomes an expensive personal card with your company's name printed on it.

Business credit is a separate thing from your personal credit

Two different identifiers do two different jobs. Your EIN (Employer Identification Number) identifies your business for tax purposes, and your D-U-N-S Number identifies it for credit purposes. Personal credit is tracked by Equifax, Experian, and TransUnion under your SSN; business credit is tracked by Dun & Bradstreet, Experian Business, and Equifax Business under your business identity. The catch for new businesses: until your business has its own track record, almost every issuer will still check your personal credit and require a personal guarantee. Most business cards expect a personal FICO of roughly 670 or higher to approve.

Business credit has its own scoring systems. The best-known is the PAYDEX score from Dun & Bradstreet, which runs 1-100 and is based purely on whether you pay vendors on time. A PAYDEX of 80 means consistent on-time payment and is the generally accepted "good" threshold; scores above 80 reflect paying early.

Why it matters down the road

A strong business credit profile is what lets you stop personally guaranteeing every loan and start getting financing on the company's merits. As an example of how lenders use these scores: until recently the SBA used a FICO Small Business Scoring Service (SBSS) prescreen for its 7(a) small loans, with a minimum of 165 (raised from 155 in 2025). The SBA has signaled it will stop requiring that prescreen for 7(a) small loans as of March 1, 2026, but the broader point stands: your business credit profile materially affects loan eligibility and terms.

Step-by-step: from zero to a business credit card and a real credit file

• Form a legal entity. Register an LLC or corporation with your state's Secretary of State. As the SBA notes, a sole proprietorship has no legal separation between you and the business, so everything stays on your personal credit. An entity is what makes a separate business credit file possible.

• Get your EIN from the IRS. Apply directly at IRS.gov. It is free (0 dollars) and issued immediately online. Never pay a third-party service for this.

• Open a dedicated business bank account. Use the EIN and your formation documents. This creates the clean financial trail bureaus and lenders look for, and many issuers want to see banking history. Note that Dun & Bradstreet generally looks for roughly six months of business banking activity before that history can influence scores.

• Register for a free D-U-N-S Number. Get it directly from Dun & Bradstreet. It is free (0 dollars) and is the identifier that opens your D&B credit file. As with the EIN, do not pay an intermediary.

• Establish vendor / trade credit first. Open a few "net-30" accounts with suppliers that report to the business bureaus (office supplies, shipping, and similar). Buy something small, pay the invoice on or before the due date, and you start generating the payment history that builds your PAYDEX score. This is the fastest, lowest-bar way to seed a business credit file before you have a card.

• Apply for a business credit card. Pick a card whose approval profile matches where you are. Expect the issuer to pull your personal credit and require a personal guarantee on your first card. If your personal FICO is below ~670, start with a secured business card, which is backed by a deposit and is far easier to approve.

• Use it deliberately and pay on time. Run real business expenses through it, keep utilization low, and pay the full statement balance by the due date every cycle. On-time payment is the single biggest driver of every business credit score.

• Confirm the card reports to business bureaus, then monitor. Not every business card reports to the commercial bureaus the way you'd hope. Check your reports across Dun & Bradstreet, Experian Business, and Equifax Business, and watch your PAYDEX and Intelliscore over time. The SBA recommends monitoring both your personal and business reports.

Common mistakes to avoid

• Skipping the entity and EIN. Putting business spend on a personal card with no entity means you are building zero business credit, just personal debt.
• Paying for free things. The EIN (IRS) and D-U-N-S Number (D&B) are both free at the source. Paid "expedited" services are unnecessary.
• Carrying a balance to "build credit." You do not need to carry a balance. Pay in full; revolving a balance just costs you interest.
• Assuming the personal guarantee disappears. Early cards almost always require it. The point of building a business profile is to eventually qualify for credit without one, not to escape responsibility on day one.

Quick reference

| Item | Source / issuer | Cost |

|---|---|---|

| EIN | IRS (irs.gov) | Free |

| D-U-N-S Number | Dun & Bradstreet | Free |

| "Good" PAYDEX score | Dun & Bradstreet | 80+ |

| Typical personal FICO for a business card | Card issuers (varies) | ~670+ |

Build the foundation in order: entity, EIN, bank account, D-U-N-S, vendor credit, then the card. Each step makes the next one easier, and within a year of disciplined, on-time payments you can have a business credit profile that finances the company on its own merits.
