Building credit for your LLC starts with separating your business finances from your personal ones, then strategically opening accounts that report your payment activity to business credit bureaus. The process takes several months of consistent on-time payments, but even a brand-new LLC can start laying the groundwork from day one.
Set Up Your LLC as a Distinct Financial Entity
Before any credit bureau will track your business, your LLC needs its own financial identity. That means three things: a formal business structure, a federal tax ID, and a dedicated bank account.
If you’ve already formed your LLC with the state, you’re past the first hurdle. Sole proprietorships don’t create a separate legal entity, which is one reason an LLC is a stronger starting point for building business credit. Next, apply for an Employer Identification Number (EIN) through the IRS. This is a nine-digit number that functions like a Social Security number for your business. It’s free, and you can get one instantly through the IRS online application tool. You’ll use your EIN to file business tax returns, open bank accounts, and apply for credit.
With your EIN in hand, open a business bank account. This creates a clear wall between personal and business spending, which matters both for liability protection and for establishing your LLC as a credible borrower. Lenders and credit agencies want to see that your business operates independently. Running everything through a personal checking account undermines that.
Get a D-U-N-S Number
Dun & Bradstreet is the oldest and most widely used business credit bureau, and your LLC needs a D-U-N-S Number to build a credit profile there. This is a unique nine-digit identifier assigned to your business. It’s free to obtain, though the standard processing time can take up to 30 business days. An expedited option is available for a fee and typically delivers within eight business days.
Start by checking whether your LLC already has a number using Dun & Bradstreet’s lookup tool. Some businesses get one automatically when a vendor or lender reports data. If you don’t have one, you’ll apply by providing your LLC’s legal name, address, phone number, owner name, legal structure, year of formation, primary industry, and employee count. A Dun & Bradstreet representative may contact you to verify the information before issuing the number.
If you have multiple business locations, each one needs its own D-U-N-S Number.
Open Net-30 Vendor Accounts
Net-30 accounts are the easiest entry point for a new LLC with no credit history. These are vendor accounts that let you buy supplies or services now and pay within 30 days, essentially a short-term line of credit. The key is choosing vendors that report your payment activity to business credit bureaus like Dun & Bradstreet, Experian, or Equifax.
Vendors known to offer net-30 terms and report to credit bureaus include office supply companies like Quill, Crown Office Supplies, and Uline, as well as industrial suppliers like Grainger and HD Supply. Others in this category include Staples, Newegg Business, Harbor Freight, and Amazon. Smaller, credit-building-focused vendors like Creative Analytics, The CEO Creative, and Wise Business Plans also report payment data and tend to approve new businesses more easily.
Start with two or three vendor accounts. Make small purchases you’d make anyway, and pay the invoices on time or early. Payment timing is the single biggest factor in your early credit profile. Even one late payment can set you back significantly when your file is thin.
Apply for a Business Credit Card
Once you have a few months of vendor payment history, a business credit card is the next step. Most business credit cards require a personal guarantee, meaning you’re personally responsible for the balance if the LLC can’t pay. This is normal for newer businesses and doesn’t defeat the purpose. As long as the card issuer reports to business credit bureaus, the payment history still builds your LLC’s credit profile.
A few cards don’t require a personal guarantee, but they set a high bar. The Brex card, for example, requires no personal guarantee and reports payments to both Dun & Bradstreet and Experian. The Mercury IO card requires a Mercury business bank account with a balance of at least $25,000. The Sam’s Club Business Mastercard waives the personal guarantee for incorporated businesses with more than two years of operating history, more than 10 employees, and at least $5 million in annual revenue.
For most new LLCs, a standard business credit card with a personal guarantee is the realistic starting point. Use it for regular business expenses and pay the balance in full each month. The on-time payment data flowing to credit bureaus is what matters most.
Understand Business Credit Scores
Unlike personal credit, where you have one main FICO score, business credit involves multiple scoring models across different bureaus. Knowing the basics helps you track your progress.
- Dun & Bradstreet PAYDEX: Ranges from 1 to 100 and measures how quickly you pay suppliers and creditors. A score of 80 or higher signals that you pay on time or early. This is the score most commonly referenced when people talk about business credit.
- Experian Intelliscore Plus: Ranges from 300 to 850, similar to a personal credit score scale. It factors in payment history, payment frequency, credit utilization, and business background. Higher is better.
- Equifax Payment Index: Ranges from 1 to 100 based on payment history, with higher scores indicating healthier credit. Equifax also calculates a separate credit risk score (101 to 992) that lenders use to decide how much credit to offer.
- FICO Small Business Scoring Service: Ranges from 0 to 300 and is used by lenders to evaluate loan terms. This score may also pull in data from the business owner’s personal credit history.
The common thread across all these models is payment history. Paying on time, or better yet early, is the single most effective way to push every score upward.
Monitor Your Business Credit Reports
Unlike personal credit reports, business credit reports are not free by law. You’ll typically need to pay to access your full reports from Dun & Bradstreet, Experian, and Equifax. Some services like Nav offer free summaries or limited access to business credit data, which can be enough to spot errors or track general progress.
Check your reports periodically to confirm that your vendor accounts and credit cards are being reported accurately. If a vendor promised to report and the tradeline doesn’t show up after 60 to 90 days, contact them directly. Errors on business credit reports are more common than you might expect, and there’s no standardized dispute process like there is for personal credit. You’ll need to reach out to each bureau individually to correct mistakes.
Build Gradually Over 6 to 12 Months
Business credit doesn’t appear overnight. A realistic timeline looks something like this: in months one and two, form your LLC, get your EIN, open a business bank account, and apply for your D-U-N-S Number. In months two through four, open two or three net-30 vendor accounts and start making purchases. By month four or five, apply for a business credit card. By months six through twelve, your payment history should be generating reportable scores across at least one or two bureaus.
As your profile strengthens, you can apply for larger lines of credit, equipment financing, or small business loans that rely more heavily on your LLC’s credit than your personal score. Each new account that reports positive payment data reinforces your profile. The goal is a steady upward trajectory built on consistent, boring, on-time payments.
