Paydex Score: The Complete Guide for Small Business Owners

If you have ever applied for business financing, a supplier account or a commercial lease, there is a good chance someone looked at your Paydex score. It is one of the most widely used business credit scores in the United States, and for many small business owners it is the first number a lender sees. Yet most owners have never seen their own.

This guide explains what the Paydex score is, how it is calculated, what a good score looks like, and the practical steps that help you build a strong one. I have spent my career in lending and business credit, and the same questions come up on almost every call. Here are the answers in plain words.

What is a Paydex score?

The Paydex score is a business credit score created by Dun & Bradstreet, one of the major business credit bureaus. It measures one thing: how promptly your business pays the vendors and suppliers that report to Dun & Bradstreet. It does not look at your revenue, your bank balance or your personal credit. It is a payment behavior score, plain and simple.

The score runs from 1 to 100. A higher number means your business pays faster. Because it is tied to your company's DUNS number, it follows your business, not you as an owner.

Think of it like a report card that only grades one subject, paying bills. That is why it carries so much weight with suppliers. When a vendor is deciding whether to give you net 30 terms, the main question is simple: will this business pay me on time?

How the Paydex scale works

The Paydex score is based on how many days early or late your business pays compared with the terms on each invoice. Here is the general scale Dun & Bradstreet uses:

The big takeaway is that 80 means on time. Anything under 80 tells a lender your business pays late at least some of the time. Anything above 80 tells them you pay early.

How Dun & Bradstreet calculates it

A few details matter here, because they explain why scores sometimes surprise owners.

• It is dollar weighted. Larger invoices count more than small ones. If you pay a big supplier late and a small one early, the big late payment pulls harder on your score.
• It uses reported trade experiences. Each account a vendor reports is called a trade experience. Dun & Bradstreet generally needs several of them from more than one vendor before it can calculate a score.
• It looks at recent history. The score reflects your payment pattern over roughly the last year or two, with recent behavior counting heavily.
• It only sees vendors that report. If your suppliers do not report to Dun & Bradstreet, your on-time payments are invisible to the score.

That last point is the one that catches most people. You can pay every bill early for ten years and still have no Paydex score if none of your vendors report.

What is a good Paydex score?

For most lenders and suppliers, 80 is the line. At 80 or above, you look like a business that pays on time. Here is how it is usually read:

A missing score is not the same as a bad score. It usually means the file is thin. Read our guide on thin business credit files to see what that means and how to fix it.

Why your Paydex score matters

Here is where a Paydex score can show up in real life:

• Business loans and lines of credit. Many lenders pull your business credit file during underwriting. A strong Paydex score supports the story that your business pays its obligations.
• Working capital and funding offers. Funders look at your business credit along with your bank statements. A clean file can help you qualify with more options.
• Vendor terms. Suppliers use it to decide whether to offer net 30 or net 60 terms, and how large a credit limit to give you.
• Leases and contracts. Landlords, equipment lessors and even large customers may check it before signing.
• Insurance. Some commercial insurers look at business credit when pricing policies.

How to build a strong Paydex score

Building a Paydex score is not complicated, but it takes a plan and some patience. These are the basics:

1. Get a DUNS number. Your Paydex score lives on your Dun & Bradstreet file, and that file is tied to your DUNS number. See what a DUNS number is.
2. Make sure your company details match. Your legal name, address and phone number should match across your state filing, your website and your business credit file. A mismatch can split your history across two files. Our guide to business credit mismatches covers this in detail.
3. Open accounts with vendors that report. Choose suppliers that report your payments to Dun & Bradstreet. Our net 30 vendors guide explains how to pick them.
4. Pay on time or early. Every invoice paid by the due date supports an 80. Paying early can push you higher.
5. Keep it going. One or two accounts can get you started. More reporting accounts over time make the score steadier.
6. Watch your file. Errors happen. A vendor may report a payment as late by mistake. Business credit monitoring helps you catch it fast.

Common Paydex myths

Myth: Paying my credit card on time builds my Paydex score. Most business credit cards do not report to Dun & Bradstreet in a way that feeds the Paydex score. They may help other business scores, but the Paydex score is about trade payments to vendors.

Myth: A new business starts at a low score. A new business usually starts with no score at all. The first reported payments set the starting point.

Myth: Paying early always means 100. It depends on how early, how large the invoices are, and how your other accounts look. Early payment helps, but it is one part of the picture.

Myth: My score is wrong, so there is nothing I can do. Businesses can ask the bureau to update incorrect company information, and vendors can correct what they report. Accurate information is what you want on file.

Paydex vs other business credit scores

The Paydex score is just one of several business credit scores. Experian has its Intelliscore, Equifax has its own business scores, and FICO has the Small Business Scoring Service that many banks use. Each one is built differently. For a side by side look, read business credit scores explained.
