How to Build Business Credit From Scratch
A step-by-step guide to building business credit, from registering your business and getting a DUNS number to opening vendor accounts, business credit cards, and establishing a standalone credit profile.
Business credit is a separate credit profile for your company, tracked by business credit bureaus (Dun and Bradstreet, Experian Business, Equifax Business) instead of the personal bureaus. A business with strong credit can qualify for financing, vendor net terms, and credit cards without a personal guarantee, and without affecting the owner's personal credit score.
Building business credit from scratch takes 12 to 24 months of consistent, deliberate activity. Unlike personal credit, it does not happen automatically through normal business operations. You have to set it up intentionally.
Why Business Credit Matters
Personal credit is tied to your Social Security Number. Business credit is tied to your business's EIN (Employer Identification Number). They are separate files at separate bureaus.
The benefits of separate business credit:
Financing independence: A business with a strong Paydex score and Experian Business credit file can qualify for business loans and lines of credit based on business revenue and history, reducing or eliminating personal guarantee requirements.
Better vendor terms: Suppliers and vendors check business credit before extending net-30 or net-60 terms. Strong business credit gets better terms and higher limits.
Personal credit protection: Business spending and debt on accounts that report to business bureaus do not affect your personal debt-to-income ratio or personal credit utilization.
Scale: Business credit limits can grow to levels that personal credit rarely reaches, supporting larger operating expenditures.
Step 1: Register Your Business as a Legal Entity
Before you can build business credit, you need a business that exists separately from you as a person.
Form an LLC or corporation. A sole proprietorship is not a separate legal entity, which limits your ability to build genuine business credit. An LLC (Limited Liability Company) is the simplest structure for most small businesses. It costs $50 to $500 to register depending on your state.
Why it matters: business credit bureaus distinguish between businesses with formal legal status and sole proprietorships operating under the owner's Social Security Number. A formally registered LLC with an EIN is treated as a proper separate entity.
Get an EIN (Employer Identification Number). This is your business's federal tax ID, analogous to a Social Security Number. Apply for free at IRS.gov. You receive the number immediately online. An EIN is required to open a business bank account and apply for most business credit accounts.
Register for state and local requirements. Depending on your industry and state, you may need a business license, DBA (doing business as) registration, or industry-specific permits. These formalize your business presence and are sometimes checked by creditors.
Set up a business address and phone number. Use your business address and a dedicated business phone number when applying for credit. Creditors verify business contact information, and using a home address and personal phone can raise flags or result in your profile not being treated as a commercial entity.
Step 2: Open a Business Bank Account
A business checking account is the foundational financial infrastructure for business credit. It demonstrates that your business has real operating activity and separates business and personal finances.
Open a business checking account with any bank in your LLC or corporation's name using your EIN. Most major banks (Chase, Bank of America, Wells Fargo) offer business checking accounts. Credit unions often have better terms for small businesses.
Use this account exclusively for business income and expenses. Commingling personal and business funds is one of the most common small business financial mistakes, and it makes accounting, taxes, and credit building all harder.
Maintain a healthy average balance. Business lenders and creditors sometimes check average daily balances when evaluating creditworthiness. A consistently funded business account signals stability.
Step 3: Get a DUNS Number
Dun and Bradstreet (D&B) is the dominant business credit bureau. Your D&B credit file is identified by a DUNS Number (Data Universal Numbering System). Many creditors, lenders, and government contractors require a DUNS number.
Apply for a free DUNS Number at dnb.com. Processing takes up to 30 days but expedited options are available. Once you have a DUNS number, a D&B credit file is created for your business.
The D&B Paydex score is a 0 to 100 score based on payment timeliness. An 80 Paydex means you consistently pay on time. A 100 means you consistently pay early. Creditors typically want a Paydex of 75 or above for standard terms and 80 or above for preferred terms.
To build your Paydex score, you need trade lines that report to D&B. That is where net-30 vendor accounts come in.
Step 4: Open Net-30 Vendor Accounts
Net-30 accounts are trade accounts where you receive goods or services and pay within 30 days (or net-60, net-90 for other terms). When suppliers report these accounts to D&B, Experian Business, or Equifax Business, they build your business credit file.
Starter net-30 vendors that commonly report to business credit bureaus and are accessible to new businesses:
- Uline: Office and shipping supplies, reports to D&B. Apply online, buy something, pay within 30 days.
- Quill: Office supplies, owned by Staples, reports to D&B and Experian Business.
- Grainger: Industrial supplies, reports to D&B.
- Summa Office Supplies: Reports to all three major business credit bureaus.
- Crown Office Supplies: Reports to all three bureaus.
- Shirtsy: Custom apparel and promotional items, reports to business bureaus.
Open three to five vendor accounts in the first two months. Buy something small each month on net-30 terms and pay within 30 days or earlier. Each on-time payment builds your Paydex score.
After three to five trade lines have two to three months of payment history each, your business credit file will have enough data to show a meaningful score.
Step 5: Open a Business Credit Card
A business credit card that reports to business credit bureaus adds revolving credit to your business profile, diversifying your credit mix.
Most small business cards (Chase Ink, Capital One Spark, Amex Business Gold) report payment history to commercial bureaus. Some also require a personal guarantee and run a personal credit check during application.
For building business credit specifically, cards that report to business bureaus are more valuable than those that only report to personal bureaus. Verify with the issuer whether they report to Dun and Bradstreet or Experian Business.
Good starter business credit cards:
- Chase Ink Business Cash: No annual fee, 5% on telecom and office supplies, reports to commercial bureaus.
- Capital One Spark Cash for Business: 2% flat, reports to commercial bureaus.
- Amex Business Blue Cash: No annual fee, reports to commercial bureaus.
Use the business card for all business expenses and pay the balance in full each month. A clean revolving account payment history accelerates your commercial credit score.
Step 6: Monitor Your Business Credit Scores
Check your business credit reports regularly, just as you would personal reports.
Dun and Bradstreet: Access your DUNS file and Paydex score at dnb.com. The basic credit report is available for free.
Experian Business: Check your Intelliscore at experian.com/businesscredit.
Equifax Business: Check your business credit file at equifax.com/business.
Look for errors. Incorrect payment dates, wrong trade line data, or another business's information appearing in your file can suppress your scores unfairly. Dispute errors directly with each bureau.
Timeline: What to Expect
| Timeframe | Activity | Expected Score Range | |-----------|----------|---------------------| | Month 1 to 2 | Register LLC, get EIN, open bank account, get DUNS, open 3 vendor accounts | No score yet | | Month 3 to 6 | Pay vendor accounts on time, open business credit card | Paydex emerging, may be 70 to 80 | | Month 6 to 12 | Consistent on-time payments, add more trade lines | Paydex 80, Experian Intelliscore 80+ | | Month 12 to 24 | Apply for business credit with no personal guarantee | Paydex 80 to 90, eligible for business-only financing | | Year 2 to 3 | Established business credit profile | Ready for larger credit lines and favorable vendor terms |
The Most Important Rule
Pay every business obligation early or exactly on time. Business credit scoring is even more sensitive to payment timing than personal credit. Paying five days early builds a better Paydex score than paying on the due date. A single late payment can drop your Paydex significantly.
Set up calendar reminders or autopay for all vendor accounts and the business credit card. The investment in building business credit is only worthwhile if you protect it with consistent payment behavior.
