Net 30 approval playbook — a fundable business credit profile in 60 days.

Every vendor approval depends on what your business looks like on paper. Get this right before you fill out a single application.

• Active business entity with EIN

  LLC or corporation filed with your state. Active status. EIN from the IRS — not your SSN. Vendors run EIN checks. A sole proprietor gets flagged differently than an LLC.

  Required for all vendor applications
• Dedicated business address

  A business address that matches your state filing. Your home address works if it matches your LLC registration. PO boxes are acceptable for some vendors. Virtual office addresses also work — verify your LLC filing matches whatever you use.

  Consistency across all applications is key
• Business phone number and email

  A dedicated business phone number (not your personal cell) and a business email (yourname@yourbusiness.com, not Gmail). These signal legitimacy during the KYB — know your business — verification vendors run.
• D-U-N-S number registered

  Register at dnb.com for free. This is your business's credit identity at Dun & Bradstreet. All vendor payment reports will attach to this number. Without it, payment data may not reach your credit file even if the vendor reports.

• Business checking account with matching address

  Open a dedicated business bank account. The address on the account must match your LLC registration. Many vendors verify this. Minimum 30 days of account age before applying is ideal.

Start with vendors known for approving new business files with minimal history. These are your first tradelines. Apply to all of these within the same 1–2 week window.

This is where most people make the mistake. They open the accounts and then don't know how to optimize the payment behavior for maximum score impact.

• ✓ Buy something — even small. Make a real purchase through each account. Stationery, cleaning supplies, shipping materials — whatever the vendor sells. The purchase activates the account and starts the payment clock.
• ✓ Pay 10–15 days early. Net 30 means you have 30 days to pay. Pay on day 15. This targets the 85–90 PAYDEX range instead of 80. Early payment is directly reflected in your score — and it compounds.
• ✓ Never go past due — ever. A single 30-day late payment on a thin business file can drop your PAYDEX from 80 to below 60. Calendar every due date before you apply. Automate payment if possible.
• ✓ Make at least 2 purchase cycles per account. One payment is a data point. Two consistent on-time payments is a pattern. Lenders and bureaus treat repeated positive history differently than a single transaction.

After 45 days of payments, your business credit file should be forming. Check it and verify the data landed correctly before you approach any lender.

• Check your D&B file — confirm all vendors reported

  Go to Dun & Bradstreet and access your business credit file. Verify that each vendor account is showing in your file with payment history. If a vendor isn't showing up, contact them directly and ask them to verify your account is being reported.
• Check your PAYDEX score

  With 3–5 accounts reporting early payment over 45–60 days, your PAYDEX should be approaching or at 80+. If it's lower than expected, verify: are all accounts reporting? Is your DUNS number attached correctly to all tradelines?

  Target: 80+ before any bank or SBA application
• Dispute any errors immediately

  Wrong payment dates, accounts linked to wrong DUNS, duplicate entries — these errors happen and they're fixable. D&B has a dispute process. Fix errors before you apply for financing or they'll hurt you during underwriting.
• Apply for Tier 2 vendors and business credit cards

  With a documented PAYDEX score and 5 tradelines, you're now ready for Tier 2 vendor terms (net 30–60 with higher limits) and business credit cards that report to bureaus. This is where your credit limits start growing significantly.
