PAYDEX Score Explained: Ranges, Calculation, and How to Improve It

A PAYDEX score is a business credit metric developed by Dun & Bradstreet to summarize how promptly a company pays suppliers and vendors. The dollar-weighted score ranges from 1 to 100, with higher scores indicating stronger payment performance. For companies that buy on trade credit, PAYDEX can affect supplier decisions about credit limits and payment terms. For B2B sellers offering net payment terms, PAYDEX may also serve as one data point when assessing whether a buyer is likely to pay invoices as agreed.

Key Takeaways

• PAYDEX measures payment performance: The score reflects how promptly a business pays reported supplier and vendor accounts.
• A score of 80 indicates prompt payment: Scores above 80 generally reflect payment before the agreed due date.
• Invoice size affects the calculation: PAYDEX is dollar-weighted, so larger reported balances can influence the score more heavily.
• Recent trade experiences matter most: D&B generally calculates PAYDEX using eligible payment experiences reported within the previous 24 months.
• Supplier reporting drives visibility: Paying on time only helps when vendors or other trade participants report the account to Dun & Bradstreet.
• Cash flow supports stronger payment habits: Faster receivables collection can help businesses pay strategic suppliers on or before their due dates.

What Is a PAYDEX Score?

The PAYDEX score is Dun & Bradstreet’s proprietary measure of a company’s historical payment performance. It is based on trade experiences submitted by suppliers and vendors, rather than on every transaction completed by the business.

Dun & Bradstreet describes PAYDEX as a dollar-weighted indicator calculated from reported payment experiences. The score focuses on whether the business pays before, on, or after the terms established by each supplier.

For example:

• An invoice paid within the agreed payment period may be reported as prompt.
• An invoice paid before its due date may support a score above 80.
• An invoice paid after the due date may be reported as slow payment.
• A significantly overdue account may have a larger negative effect, especially when the reported balance is substantial.

PAYDEX is different from a personal credit score. It does not directly measure personal revolving credit utilization, mortgage history, or the account age of an individual owner. It is intended to describe the business’s payment behavior based on qualifying trade data associated with its D-U-N-S Number.

For sellers reviewing applications for business trade credit, PAYDEX can provide useful context. However, it should not be treated as a complete underwriting decision by itself. Revenue stability, business identity, industry risk, financial records, outstanding obligations, transaction size, and previous payment behavior may also be relevant.

Resolve Pay’s business credit checks combine available business information with automated analysis and credit expertise, helping merchants evaluate buyers before offering payment flexibility.

How PAYDEX Score Ranges Work

PAYDEX generally ranges from 1 to 100. Dun & Bradstreet states that a score of 80 represents payments made within agreed terms, while scores above 80 indicate that reported payments were generally made earlier than required.

Scores From 80 to 100

Scores in this range generally represent prompt or early payment.

• 80: Payments are generally made within terms.
• Above 80: Payments are generally made before the due date.
• Near 100: Reported payment behavior reflects payment substantially earlier than terms.

A score of 80 is commonly viewed as a positive result because it indicates that the company generally pays as agreed. A score above 80 can demonstrate a pattern of early payment, but businesses should not sacrifice essential working capital merely to pursue a higher score.

Scores From 50 to 79

Scores below 80 generally indicate some degree of payment beyond terms.

The specific score depends on the distribution and value of reported payment experiences. A business with occasional late invoices may still have a stronger score than a business with repeated or substantial delinquencies.

Scores From 1 to 49

Scores in the lower part of the range indicate more serious or frequent payment delays. Suppliers reviewing a low score may choose to investigate further, request additional documentation, reduce an available credit limit, or require different payment arrangements.

PAYDEX should still be considered in context. A low score may reflect cash flow problems, disputed invoices, administrative errors, incomplete reporting, or a limited number of trade experiences. Reviewing the underlying report is more informative than relying only on the headline score.

How the PAYDEX Score Is Calculated

Dun & Bradstreet calculates PAYDEX from individual account-level trade experiences submitted by participating suppliers and vendors.

Dollar-Weighted Payment Data

PAYDEX is dollar-weighted. This means the reported value of an account affects how strongly that account influences the calculation.

A larger invoice or open balance may therefore have a greater effect than several small purchases. A late payment involving a major supplier can materially weaken the score even when smaller accounts are paid promptly.

Businesses trying to maintain strong payment performance should:

• Track due dates for their largest supplier relationships.
• Resolve disputed invoices before they become seriously overdue.
• Schedule payments early enough to account for bank processing delays.
• Verify that suppliers applied payments to the correct invoices.
• Maintain adequate liquidity for recurring trade obligations.

Payment Categories

Reported trade experiences may be categorized based on how the company paid relative to the agreed terms. Common categories include:

• Anticipated or early payment
• Prompt payment
• Slow payment beyond terms
• More serious delinquency

D&B then combines the qualifying experiences and applies index values based on their payment categories and dollar amounts.

Eligible Trade Experiences

D&B documentation states that PAYDEX generally reflects trade experiences reported during a 24-month period. The date of the reported experience and the date of the underlying sale must meet D&B’s eligibility requirements.

Dun & Bradstreet may use up to 875 recent payment experiences when sufficient trade data is available.

Because the calculation depends on reported data, the score may not include every supplier the company pays. Some vendors report regularly, some report only limited account information, and others do not participate in D&B’s trade exchange.

How to Check Your PAYDEX Score

Businesses typically access PAYDEX through Dun & Bradstreet’s business credit products or monitoring services that include D&B data.

Review the Complete Credit File

When reviewing a D&B report, do not focus only on the numerical score. Examine the underlying trade information for:

• Incorrect balances
• Duplicate accounts
• Payments applied to the wrong period
• Accounts that do not belong to the business
• Missing positive trade experiences
• Delinquencies caused by unresolved invoice disputes
• Supplier names that are difficult to recognize

A supplier may appear under a parent company, financing provider, or abbreviated reporting name. Compare the report with accounts payable records before concluding that an account is unfamiliar.

Correct Inaccurate Information

If an account is inaccurate, gather documentation such as:

• Supplier statements
• Paid invoices
• Bank confirmations
• ACH records
• Cleared checks
• Email correspondence about disputes
• Credit memos or corrected invoices

Submit the documentation through the appropriate D&B review or dispute process. Updating information with Dun & Bradstreet does not automatically correct separate files held by Experian, Equifax, or other business credit providers.

The federal Fair Credit Reporting Act primarily addresses consumer reporting. Business credit reporting does not provide all the same access and dispute rights that consumers receive for personal credit files, although business data providers maintain their own correction procedures.

How to Improve a PAYDEX Score

Improving PAYDEX requires consistent payment management and accurate supplier reporting. There is no single transaction that guarantees a particular score.

Pay Suppliers Within Agreed Terms

The most important step is paying qualifying trade accounts by their contractual due dates. Businesses should use a centralized accounts payable calendar instead of relying on individual email reminders.

Useful practices include:

• Recording the invoice date and due date separately.
• Confirming whether terms begin from shipment, delivery, or invoice issuance.
• Scheduling payments before weekends and holidays.
• Accounting for check delivery and bank processing time.
• Escalating disputed invoices before the due date.
• Assigning responsibility for approving large invoices.

Consider Early Payment Carefully

Payment before the due date may support a score above 80, but early payment should be balanced against the company’s working capital needs.

Prioritize early payment when it provides a clear operational benefit, such as:

• Preserving a strategic supplier relationship
• Securing an early payment discount
• Maintaining access to a critical credit line
• Supporting a time-sensitive credit application
• Avoiding processing delays around holidays or month-end

A business should not weaken payroll, tax reserves, or essential operating liquidity solely to pay every invoice early.

Confirm Which Vendors Report

A supplier account cannot influence PAYDEX when no qualifying experience is reported to D&B.

Ask major vendors whether they participate in business credit reporting and how frequently they submit updates. Do not assume that every office supply, telecommunications, shipping, fuel, or equipment account reports to Dun & Bradstreet.

The reporting policy may also differ by account type. A supplier may report formal trade accounts while excluding ordinary card purchases or transactions paid at checkout.

Keep Business Records Consistent

Credit data can become fragmented when business records use inconsistent names, addresses, or registration details.

Keep the following information aligned:

• Legal business name
• Trade name or DBA
• Business address
• Employer Identification Number
• State registration
• Phone number
• Industry classification
• D-U-N-S Number

Consistency helps reporting agencies match supplier data to the correct business file.

Establishing PAYDEX for a New Business

A new business must first establish an identifiable D&B credit file and qualifying trade history.

Obtain a D-U-N-S Number

A D-U-N-S Number is a unique nine-digit business identifier assigned by Dun & Bradstreet. It helps connect reported trade experiences to the correct company.

Businesses should obtain or verify their D-U-N-S Number directly through Dun & Bradstreet and confirm that the associated company information is accurate.

Separate Business and Personal Finances

Maintain distinct business banking and accounting records. This improves financial controls and makes it easier to document supplier payments.

Important foundational steps include:

• Opening a business bank account
• Using the company’s legal name on supplier applications
• Maintaining current state registration
• Obtaining an Employer Identification Number when required
• Recording invoices and payments in accounting software
• Avoiding informal payments that cannot be matched to a business invoice

The IRS provides guidance on obtaining an Employer Identification Number for eligible businesses.

Establish Genuine Supplier Relationships

New companies should focus on vendors that provide products or services the business actually needs. Opening unnecessary accounts merely to pursue a credit score can create avoidable fees, administrative work, and payment risk.

Before accepting trade terms, confirm:

• The due date
• Any late-payment provisions
• How invoices will be delivered
• Accepted payment methods
• Whether the supplier reports account activity
• Which business credit agencies receive the data

A PAYDEX score develops from reported activity. The timing varies based on when suppliers submit information and whether enough eligible trade experiences are available.

How PAYDEX Affects Business Decisions

PAYDEX can influence commercial decisions, but its importance differs by lender, supplier, landlord, insurer, and industry.

Supplier Credit Decisions

Suppliers may use PAYDEX when deciding whether to:

• Approve a trade account
• Set a credit limit
• Offer Net 30, Net 60, or other terms
• Request a deposit
• Require cash on delivery
• Review an existing account

A strong score can support a credit application, but approval is never guaranteed. Suppliers may also evaluate order size, financial statements, ownership information, industry conditions, and internal payment history.

Lending and Financing

Some lenders review D&B information as part of a broader commercial underwriting process. PAYDEX alone does not determine loan approval or interest rates.

The SBA discontinued mandatory agency use of the FICO Small Business Scoring Service for 7(a) Small Loan screening effective March 1, 2026. Lenders must follow current SBA underwriting requirements, and they may still use permissible business or consumer credit information within their own processes.

Commercial Relationships

Business credit information may also be reviewed during:

• Commercial lease applications
• Insurance underwriting
• Distributor onboarding
• Partnership due diligence
• Contract negotiations
• Vendor qualification

Companies should therefore monitor the accuracy of their business credit information even when they are not actively applying for financing.

PAYDEX Compared With Other Business Credit Scores

PAYDEX is only one part of a business credit profile.

D&B PAYDEX

• Range: 1 to 100
• Primary focus: Supplier and vendor payment performance
• Data type: Reported trade experiences
• Notable feature: Dollar-weighted calculation

Experian Intelliscore Plus

• Range: Commonly 1 to 100
• Primary focus: Commercial credit risk
• Data type: Payment history, public records, collections, and other business information

Equifax Business Risk Scores

Equifax provides multiple commercial scores rather than a single universal business score. The range and factors depend on the specific product used by the lender or supplier.

FICO SBSS

• Range: 0 to 300
• Primary focus: Small business credit risk
• Data type: May combine business bureau data, owner consumer credit, financial information, and application details

Because these models use different inputs, a company can have a strong PAYDEX score and a weaker result elsewhere. Businesses should monitor multiple files when preparing for significant financing or supplier applications.

How Accounts Receivable Affects Payment Capacity

PAYDEX measures how a business pays suppliers, but accounts receivable performance affects whether sufficient cash is available to make those payments.

When customers pay late, businesses may struggle to meet their own obligations even when sales are growing. Improving the credit-to-cash process can reduce that pressure.

Faster Invoicing and Collections

An accounts receivable platform can support payment capacity through:

• Prompt invoice generation
• Automated payment reminders
• Centralized receivables visibility
• Digital payment workflows
• Reconciliation automation
• Organized collection follow-up

Resolve Pay helps B2B merchants manage invoicing, payment reminders, reconciliation, credit workflows, and collections within a unified platform.

Better Buyer Credit Decisions

Before extending terms, sellers can use credit check automation to evaluate whether the buyer appears capable of handling the requested credit line and payment period.

PAYDEX may contribute to the assessment, but Resolve Pay’s underwriting process can also consider additional business signals and human credit expertise. This broader approach helps merchants avoid making decisions from one bureau score alone.

Advance Payments on Approved Invoices

For eligible merchants and approved buyers, Resolve Pay can provide non-recourse advance payments on qualifying invoices while the buyer retains the agreed payment period.

This can help merchants:

• Access cash sooner
• Offer flexible terms without waiting for the full payment period
• Reduce exposure to qualifying buyer payment risk
• Maintain predictable operating liquidity
• Pay suppliers without depending entirely on customer payment timing

Resolve Pay also supports net terms management, branded buyer payment workflows, and automated follow-up. Available terms, advance amounts, and credit lines remain subject to verification and approval.

Strengthen Payment Performance With Resolve Pay

PAYDEX score begins with consistent supplier payment practices, accurate reporting, and reliable cash flow. Businesses should review their D&B file, correct errors, understand which vendors report, and pay major obligations according to agreed terms.

Resolve Pay supports the cash flow side of that process. Its B2B payments platform combines buyer credit decisions, net terms, invoicing, payments, reconciliation, and collections workflows. Merchants can offer approved buyers flexible payment terms while receiving faster access to funds on qualifying invoices.

By improving receivables visibility and reducing the delay between invoicing and available cash, Resolve Pay can help businesses maintain stronger supplier relationships and more consistent payment performance.
