How to Build Business Credit for Your New LLC

If you formed your LLC in the last year, your business credit file is either empty or nonexistent, and that is normal. Building it takes three things in order: separating your finances, opening accounts that actually report, and paying them on time. Most owners can have a usable file within 90 days.

Why Does a New LLC Need Business Credit in the First Place?

Business credit is what lets your company borrow, lease, and get vendor terms without your personal social security number or credit score carrying the risk. Without it, every loan application, equipment lease, or net-30 supplier account gets underwritten against your personal file instead, which caps how much capital your business can access and puts your own score on the line for business debt.

A business credit score also travels with the company, not with you. If you ever bring on a partner, sell the business, or just want a clean line between “my money” and “the business’s money,” a credit file that exists independently of your personal one is what makes that possible.

What’s the Very First Step to Building Business Credit?

The first step is separating your business financially from you, on paper, before you apply for anything. That means:

  • An EIN from the IRS (free, and different from your Social Security number)
  • A business bank account opened in the LLC’s name
  • A dedicated business phone number and address
  • A D-U-N-S Number from Dun & Bradstreet (free, and required before most bureaus will open a file on you)

Skip this step and every account you open afterward still gets tied back to your personal credit, which defeats the purpose.

Which Accounts Should a New LLC Open First?

Once the business is separated on paper, open accounts in roughly this order:

  1. A net-30 vendor account. Suppliers like office or shipping vendors that bill you in 30 days and report to business bureaus. These are the easiest business credit to qualify for with no history yet.
  2. A business credit card. Look for one that reports to at least one of the major business bureaus (not all of them do).
  3. A small business line of credit, once you have a few months of on-time vendor and card payments behind you.

Pay every one of these early or on time. A single late payment on a thin file does more damage than it would on an established one, because there is less good history to offset it.
