PAYDEX score: What it is and how to improve it

When you apply for financing or ask a supplier for net-30 terms, someone is checking whether your business pays its bills on time. Most lenders and suppliers want to see a score of 80 or higher before they say yes.

A PAYDEX score is Dun & Bradstreet's business credit score, from 1 to 100, that measures how promptly your business pays its bills. The higher you score, the earlier you're paying, and the less risk you look like to anyone deciding whether to extend you credit.

Get this number right, and you'll unlock better financing, stronger vendor terms, and the credit you need to grow.

What is a PAYDEX score

A PAYDEX score is a business credit score from Dun & Bradstreet, ranging from 1 to 100, that measures how reliably your business pays its bills. It's based entirely on payment data reported by vendors, suppliers, and creditors. Unlike personal credit scores, it doesn't consider personal debt or credit utilization.

The score ranges from 1 to 100, with 80 generally considered the benchmark for good business credit. A score of 80 means you're paying on time, while higher scores indicate early payments. Lower scores reflect late payments and higher risk.

How the PAYDEX score is calculated

PAYDEX scores are calculated based on your company's payment history with vendors and suppliers. The system evaluates how consistently you pay and how early or late those payments occur.

Payment timing plays a critical role in determining your score:

• Pay early: paying ahead of the due date can push your score above 80 and signals low credit risk
• Pay on time: paying on the due date generally keeps you near 80, the low-risk benchmark; it's acceptable but doesn't show proactive cash management
• Pay late: paying after the due date lowers your score and moves you toward D&B's moderate- or high-risk range

Your score is also dollar-weighted, so larger invoices move it more than small ones, according to Dun & Bradstreet.

One nuance many owners miss: most credit card payments usually don't count. PAYDEX is built from trade credit, the invoices vendors and suppliers report to Dun & Bradstreet when they let you pay later on terms like net 30. Because most business card activity isn't reported as a trade experience, it usually won't move your score.

What is a good PAYDEX score

A good PAYDEX score is 80 or higher, which Dun & Bradstreet classifies as low risk. At 80, you're paying your bills on time, right when they come due.

To score above 80, you need to pay early, not just on time. The further ahead of terms you pay, the higher your score climbs toward 100. Paying exactly on the due date caps you at 80, so early payment is what separates a good score from a great one.

PAYDEX score ranges chart

Each PAYDEX score maps to how many days beyond terms you typically pay. The chart below shows how the ranges line up with payment timing and risk:

For reference, a score of 80 means you're paying within terms, and anything above 80 means you're paying early. Scores below 80 signal payments made beyond terms.

Why your PAYDEX score matters

Your PAYDEX score plays a major role in how lenders evaluate your business for loans and credit lines. A higher score can lead to lower interest rates, higher credit limits, and faster approvals. On the other hand, a low score can limit your access to financing or increase borrowing costs.

Suppliers also use your PAYDEX score to determine payment terms and credit limits.

• Better payment terms: A high score can qualify you for Net 30 or Net 60 terms. This improves your cash flow by giving you more time to pay.
• Higher credit limits: Vendors may extend larger lines of credit to businesses with strong payment histories. This supports growth and purchasing flexibility.
• Faster approvals: Suppliers are more likely to onboard businesses with reliable payment behavior. This helps you establish new partnerships quickly.

Beyond financing, your PAYDEX score can influence insurance premiums, contract eligibility, and business partnerships. A strong score signals reliability and financial stability, which builds trust across stakeholders.

PAYDEX vs. other business credit scores

Each credit bureau scores your business differently, and lenders may check more than one, so it helps to know how PAYDEX compares. The table below lines up the major business credit scores side by side.

PAYDEX is unique in focusing only on payment performance, unlike scores that also weigh factors like credit utilization, according to Dun & Bradstreet. Experian confirms its Intelliscore Plus scale of 1 to 100, the FICO SBSS range of 0 to 300 is documented for that score, and the Equifax Business Credit Risk Score range of 101 to 992 is published for that model.

How to get and check your PAYDEX score

Not every business has a PAYDEX score. To generate one, you need a D-U-N-S number and vendors reporting your payment experiences to Dun & Bradstreet. Until those trade experiences are on file, D&B can't calculate a score.

To check your PAYDEX score, you'll need to access your business credit profile through Dun & Bradstreet. You can view basic information for free, but detailed reports often require a paid subscription.

Start by visiting the D&B website and searching for your business profile. If your business is already registered, you can claim your profile and review your credit data. Regular monitoring helps you track changes and identify issues early.

You can check your score for free or through a paid service. D&B Credit Insights Free shows directional changes and the risk range for your PAYDEX at no cost, not the actual number. To see the actual PAYDEX number, you'll need the paid D&B Credit Insights Basic plan.

Getting your D-U-N-S number and tradelines

A D-U-N-S number is a unique identifier assigned to your business by Dun & Bradstreet. It's required to generate a PAYDEX score and establish a business credit profile.

To get a D-U-N-S number:

1. Visit the Dun & Bradstreet website and submit your business information
2. Provide details like your legal name, address, and ownership structure
3. Wait for processing, which typically takes up to 30 business days for free applications

Expedited options are available for a fee if you need faster processing.

A D-U-N-S number alone won't generate a score. You also need to open accounts with vendors that report to D&B, since your score is built from the trade experiences they submit.

Understanding your PAYDEX report

Your PAYDEX report includes detailed information about your business credit activity and payment performance.

• Payment history: Shows how quickly you pay vendors over time. Consistent early payments improve your score.
• Trade lines: Lists vendor accounts that report to Dun & Bradstreet. More active trade lines strengthen your profile.
• Credit limits: Displays the amount of credit extended by vendors. Higher limits can signal stronger financial stability.
• Payment trends: Highlights patterns in your vendor payment behavior. Sudden changes in vendor payment management may indicate risk to lenders.

Watch for red flags like missing trade lines, incorrect payment data, frequent late payments, or limited reporting activity.

How to improve your PAYDEX score

Improving your PAYDEX score requires consistent, proactive payment behavior and strong vendor relationships. Small changes in how you manage vendor payments can have a significant impact over time.

Pay all business bills early or on time, with a focus on early payments for maximum impact. Establish trade credit with vendors that report to Dun & Bradstreet to build your credit profile. Monitor your report regularly and dispute any inaccuracies to maintain accuracy.

To improve your score, follow these five steps:

1. Open three or more net-30 accounts with vendors that report to Dun & Bradstreet.
2. Pay every invoice ahead of the due date, not just on time.
3. Ask non-reporting vendors to start reporting your payments to D&B.
4. Dispute any inaccurate late payments on your report.
5. Monitor your report regularly to catch and correct errors early.

Building trade credit relationships

Establishing trade credit is essential for building your PAYDEX score, since it relies on vendor-reported data.

Net-terms suppliers, like office and industrial vendors such as Uline, Quill, and Grainger, are common starting points. Not all vendors report to Dun & Bradstreet, though, so confirm each one reports before opening an account, otherwise your payments won't build your score.

• Start with net terms vendors: These vendors offer credit without requiring a long credit history. This helps you establish your first trade lines.
• Request reporting confirmation: Not all vendors report to D&B, so confirm before opening accounts. This ensures your payments contribute to your score.
• Maintain small, consistent purchases: Regular activity shows reliability and builds a positive payment history. Over time, this strengthens your credit profile.

Payment strategies for maximum impact

Paying early is one of the most effective ways to improve your PAYDEX score. Even paying a few days ahead of the due date can make a measurable difference.

For example, on net 30 terms, paying well before day 30 helps your score, paying right at the deadline keeps it steady, and paying late pulls it down.

Creating a consistent payment schedule helps you stay ahead of deadlines and maintain a strong score. Using a business credit card that reports to major bureaus—like the Ramp Business Credit Card—ensures that on-time payments automatically build your PAYDEX profile alongside vendor trade lines.

How long it takes to reach an 80 PAYDEX score

Reaching an 80 PAYDEX score is a staged process whose speed depends on how fast your vendors report. Here's what a typical build looks like:

1. Get a D-U-N-S number and open tradelines with vendors that report to Dun & Bradstreet, then pay before the due date
2. As those vendors report your invoices, your payment experiences start reaching D&B
3. Your score appears once enough trade experiences are on file
4. From there, keep paying early to build toward and hold a score of 80 or higher

There's no standard timeline, since D&B notes it depends on how quickly your vendors report. Treat the path above as illustrative, not a guarantee.

Common PAYDEX score mistakes to avoid

Many businesses unintentionally damage their PAYDEX score by overlooking key credit practices. Understanding these mistakes helps you avoid setbacks and maintain strong credit:

1. Ignoring vendor reporting

If your vendors don't report to Dun & Bradstreet, your payments won't impact your PAYDEX score. You shouldn't assume all vendors automatically report your payment activity to Dun & Bradstreet. In reality, many vendors don't report unless you request it or use specific programs. So you could be making timely payments without building your PAYDEX score.

To prevent this, confirm reporting practices upfront and prioritize vendors that contribute to your credit profile.

2. Paying only on time instead of early

Many businesses don't realize that simply paying on time isn't enough to achieve a top-tier PAYDEX score. If you consistently wait until the due date, your score may plateau around 80 instead of improving further. This can limit your access to the best financing terms and vendor relationships.

Building a habit of early payments, even a few days ahead, can make a noticeable difference over time.

3. Failing to monitor your report

Errors in your credit report can lower your score without you realizing it. Issues like missing trade lines or incorrectly reported late payments can drag down your score without your knowledge.

Regular monitoring helps you catch and correct issues before they affect your business. Over time, these inaccuracies can affect your ability to secure credit or favorable terms.
