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.
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:
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.
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 in this range generally represent prompt or early payment.
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 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 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.
Dun & Bradstreet calculates PAYDEX from individual account-level trade experiences submitted by participating suppliers and vendors.
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:
Reported trade experiences may be categorized based on how the company paid relative to the agreed terms. Common categories include:
D&B then combines the qualifying experiences and applies index values based on their payment categories and dollar amounts.
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.
Businesses typically access PAYDEX through Dun & Bradstreet’s business credit products or monitoring services that include D&B data.
When reviewing a D&B report, do not focus only on the numerical score. Examine the underlying trade information for:
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.
If an account is inaccurate, gather documentation such as:
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.
Improving PAYDEX requires consistent payment management and accurate supplier reporting. There is no single transaction that guarantees a particular score.
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:
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:
A business should not weaken payroll, tax reserves, or essential operating liquidity solely to pay every invoice early.
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.
Credit data can become fragmented when business records use inconsistent names, addresses, or registration details.
Keep the following information aligned:
Consistency helps reporting agencies match supplier data to the correct business file.
A new business must first establish an identifiable D&B credit file and qualifying trade history.
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.
Maintain distinct business banking and accounting records. This improves financial controls and makes it easier to document supplier payments.
Important foundational steps include:
The IRS provides guidance on obtaining an Employer Identification Number for eligible businesses.
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:
A PAYDEX score develops from reported activity. The timing varies based on when suppliers submit information and whether enough eligible trade experiences are available.
PAYDEX can influence commercial decisions, but its importance differs by lender, supplier, landlord, insurer, and industry.
Suppliers may use PAYDEX when deciding whether to:
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.
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.
Business credit information may also be reviewed during:
Companies should therefore monitor the accuracy of their business credit information even when they are not actively applying for financing.
PAYDEX is only one part of a business credit profile.
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.
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.
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.
An accounts receivable platform can support payment capacity through:
Resolve Pay helps B2B merchants manage invoicing, payment reminders, reconciliation, credit workflows, and collections within a unified platform.
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.
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:
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.
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.
Resolve Pay helps merchants improve cash flow by automating invoicing, payment reminders, reconciliation, and collections. For qualifying invoices, merchants may also receive non-recourse advance payments before buyers reach their payment deadlines. Faster access to receivables can make it easier to pay suppliers within agreed terms, although Resolve Pay does not directly control PAYDEX scores.
Resolve Pay does not guarantee that activity processed through its platform will be reported to Dun & Bradstreet or directly affect a PAYDEX score. Businesses should confirm reporting practices with each supplier, lender, or trade participant whose account activity they expect to appear in their D&B credit file.
PAYDEX may be one of several available business credit signals considered during a buyer assessment. Resolve Pay combines business information, automated analysis, behavioral signals, and human credit expertise to help merchants evaluate buyers before approving credit lines or net payment terms.
Resolve Pay helps merchants offer approved buyers flexible net payment terms while managing credit decisions, invoicing, payment workflows, reminders, reconciliation, and collections. Eligible merchants may receive faster payment on qualifying invoices while buyers retain their approved payment period.
Resolve Pay cannot directly change, update, or guarantee an improvement in a company’s PAYDEX score. However, its accounts receivable and payment workflows can help merchants collect customer payments sooner, strengthen cash flow, and maintain more consistent supplier payment practices. Any PAYDEX improvement still depends on qualifying payment experiences being accurately reported to Dun & Bradstreet.
