Why this matters
Business credit is built slowly and needed suddenly, for a lease, a loan, or a card without a personal guarantee. Founders who never establish a business credit file end up personally guaranteeing everything for years.
What "done" looks like
- Your business has a DUNS number on file with Dun & Bradstreet
- At least one or two accounts (card, vendor terms, or loan) report payments to business credit bureaus
- You've seen your business credit reports, and your business name, address, and phone are consistent everywhere
How to do it
- Get a DUNS number, free directly from Dun & Bradstreet; it anchors your D&B credit file.
- Confirm what reports. Ask your card issuer, and consider net-30 vendor accounts with suppliers you'd buy from anyway, reporting varies by vendor, so verify before opening.
- Pay early, not just on time. Paying ahead of terms, not just on them, is what raises your PAYDEX.
- Keep utilization light, steady, modest, fully paid activity builds a better file than maxed lines.
- Monitor your file through the bureaus or a service like Nav, and dispute errors in writing.
- Keep your identity consistent, mismatched names or addresses fragment your file.
Common mistakes
- Opening "credit-building" vendor accounts that don't actually report to any bureau
- Assuming personal credit habits transfer, business bureaus weight payment timing differently, and business credit reports are not private
- Letting one payment run late: business scores react quickly to slow-payment history
Real-world examples
- Dun & Bradstreet's PAYDEX score ranges 0-100; a score of 80 indicates payments made on terms, with higher scores reflecting early payment.
- The DUNS number is issued free by Dun & Bradstreet and may still be used in vendor onboarding, but U.S. federal entities have used the Unique Entity ID instead since 2022.
From a founder's point of view
Business credit is a record of promises kept on schedule, compiled whether or not you're paying attention. Better to feed it deliberately for two years than to need it and find an empty file.
Rule of thumb
At least one account reporting, zero late payments, and you've read your own business credit report, that's the minimum viable credit-building machine.
