Every business credit conversation eventually lands on the same number: get your Paydex to 80. Here is what the score actually is, how Dun & Bradstreet calculates it, and the shortest honest path to 80 and beyond.
What a Paydex score is
Paydex is Dun & Bradstreet’s business credit score, running 0 to 100, tied to your company’s DUNS number. Unlike a consumer credit score, which blends payment history with utilization, age, inquiries, and account mix, Paydex is nearly a single-variable score: how early or late your business pays the trade credit that gets reported to D&B.
That makes it refreshingly controllable. You cannot quickly manufacture ten years of credit history, but you can absolutely control whether this month’s invoices get paid early.
How the score maps to payment timing
| Paydex | What it means |
|---|---|
| 100 | Pays roughly 30 days ahead of terms |
| 90 | Pays roughly 20 days ahead of terms |
| 80 | Pays exactly on terms |
| 70 | Pays about 15 days beyond terms |
| 60 | Pays about 22 days beyond terms |
| 50 and below | Pays 30 or more days beyond terms |
Two details worth knowing. First, the score is dollar-weighted: larger reported balances influence it more than tiny ones. Second, it only counts reported experiences: perfect payments to vendors that never report do not exist as far as Paydex is concerned.
Why 80 matters so much
An 80 tells every vendor and lender who checks D&B one simple thing: this business pays as agreed. Many trade credit programs treat 80 as the approval threshold, and plenty of underwriting checklists use it as the line between “extend terms” and “ask for prepayment.” It is not the ceiling, it is the credibility floor, and crossing it changes which applications approve.
How to get a Paydex score of 80, step by step
- Get your DUNS number. Free, directly from Dun & Bradstreet. No DUNS, no file, no score. More on the bureau itself in our business credit bureaus guide.
- Make your business verifiable. Entity, EIN, matching address and phone, business bank account. Vendors verify before they approve, and approvals are what create trade lines.
- Open two to five vendor accounts that report to D&B. This is the entire engine. Our net 30 vendor guide covers which account types report and how to verify before buying.
- Buy modestly and pay early. On-terms payment earns the 80; early payment earns more. Set payment reminders for a week after the invoice, not a day before the deadline.
- Wait out the reporting cycle. Vendors report monthly; D&B typically issues the score with two to three reporting trade lines. Around 90 days from a standing start is normal, per the full business credit timeline.
- Keep the lines active. A stale file with no recent payment experiences goes quiet. Small regular orders keep the score alive and current.
Going past 80
Since the scale rewards early payment, the same spending pays twice: settle invoices 20 to 30 days ahead of terms and the score climbs toward 90 and 100. A 90-plus Paydex on an aged file is the kind of profile that gets vendor credit limits raised without asking and makes lenders stop caring about your personal credit score. The step-up path from there, through store cards to real credit lines, is the ladder our Business Credit Builder program walks clients through, with D&B monitoring built in so you watch the score move.
Common Paydex mistakes
- Paying unreported vendors perfectly and wondering why nothing changes. Verify reporting first.
- Letting one invoice slide on a thin file. With two trade lines, one late payment is half your track record.
- Confusing on-time with early. On-time maintains an 80; early is what builds beyond it.
- Ignoring the file between applications. Errors and stale company data cost points silently; monitoring catches them early.
The bottom line
Paydex is the most controllable score in credit: two to three reporting trade lines, paid early, every month.
