Most business owners know about the Paydex™ score — but did you know it’s only one of several scores that Dun & Bradstreet® uses to evaluate your company’s creditworthiness? In this guide, we’ll break down every score you’ll see on a D&B business credit report, which ones actually matter, and how to optimize your file to unlock higher lending potential.
What Is the D&B Paydex™ Score?
The Paydex™ score is the most widely known Dun & Bradstreet® business credit score. It’s a proprietary, dollar-weighted indicator of your business’s past payment behavior. The score ranges from 1 to 100, with a score of 80 generally considered “perfect” — meaning all bills were paid on time.
Scores >80 indicate early payments (rare)
Scores <80 mean one or more payments were late
You must have at least 3 reporting tradelines before D&B can generate a Paydex™ score
Important: A Paydex™ score of 80 is not the same as an 800 personal FICO® score. It’s not a cumulative number — it’s simply a pass/fail indicator for on-time payments. Once you hit 80, your score does not increase further unless vendors report early payment terms (which is uncommon).
Why an 80 Paydex™ Isn’t Enough
A lot of business credit advice online implies that an 80 Paydex™ is the end goal — but that’s not the case.
While a Paydex™ score is an essential stepping stone for obtaining vendor accounts and net-terms financing, it’s only one of the scores that matter to creditors and lenders.
To truly build a powerful business credit profile, you need to understand and develop all the scores that matter.
The Dun & Bradstreet® Scores You’ll See
Here are the six primary scores D&B may include on your report:
| Score Name | What It Measures | Importance |
|---|---|---|
| Paydex™ | Past payment performance (based on tradelines) | ⭐ High |
| Maximum Credit Recommendation | Suggested maximum amount of credit to extend | ⭐ High |
| D&B Rating | Overall size and risk rating based on financials and firmographics | ⭐ High |
| Delinquency Score | Likelihood of late payments in next 12 months | Medium |
| Failure Score | Risk of business failure or bankruptcy | Medium |
| Viability Rating | D&B’s predictive analytics rating for operational risk | Medium |
While all of these may appear in your file, only the first three carry the most weight when it comes to getting approved for real business credit.
Which Scores Matter Most — and Why
1. Paydex™
Covered above — key for getting started, but not the full picture.
2. Maximum Credit Recommendation
This is D&B’s estimate of how much credit should be extended to your business. It’s based on your payment history, business type, employee count, and industry risk level.
This is often the single most influential metric lenders look at when deciding whether to approve you for $500 or $50,000.
3. D&B Rating
A combination of your financials (if available) and firmographics — including your time in business, number of employees, and industry classification.
The D&B Rating shows whether you’re a 1-person LLC or a 50-employee corporation — and lenders use it to calibrate their risk appetite accordingly.

How to Establish a Paydex™ Score the Right Way
Your Paydex™ score starts forming once you have 3 active vendors reporting to D&B.
At TrueBuild, we call this “Layer 1” — the foundational vendors. To ensure your vendors report successfully:
Make purchases of at least $50–$100
Pay your NET30 invoices on time or early
Wait for the data to report organically
⚠️ Warning: Never call vendors or D&B to ask when they’ll report. It makes your company look like a “credit hustler.” Vendors may flag your file and withhold reporting altogether.
Common Misconceptions About Paydex™
Myth: 80 Paydex™ = 800 FICO®
➡️ Wrong. Paydex™ is a simple indicator of on-time payment, not a cumulative score.
Myth: More tradelines = higher Paydex™
➡️ Wrong. Once you hit an 80, adding more won’t increase the score — but missing a payment will lower it.
Myth: Paydex™ is all lenders look at
➡️ Wrong. Real lenders look at your Maximum Credit Recommendation and D&B Rating — not just Paydex™.
What You Should Focus On
If you’re building business credit the right way, here’s what really matters:
- Build 3–5 vendor tradelines to generate your Paydex™
- Make sure your business profile is accurate with D&B
- Focus on Maximum Credit Recommendation & D&B Rating
- Don’t rush the process — let tradelines report naturally
- Use the right tools to monitor your progress
