Dun & Bradstreet PAYDEX Score: The Business-Owner's Guide

Your Dun & Bradstreet PAYDEX score is a 1-to-100 number that shows how promptly your business pays its vendors and suppliers — 80 means you pay exactly on the due date, above 80 means you pay early, and below 80 means you pay late. Unlike a personal FICO score, PAYDEX ignores your credit utilization, income, or how much debt you carry; it is built almost entirely from trade experiences — records of individual bills, reported by the companies you buy from, weighted by the dollar size of each account. A score of 80 or higher is the practical benchmark most suppliers, insurers, and net-terms programs look for. The catch every owner should understand up front: PAYDEX only exists once vendors actually report your payments to D&B, so a brand-new EIN with a real revenue history can still show "no score" — and that gap is exactly why owners who need capital now shouldn't wait on a trade score to mature before applying for revenue-based funding.

How the PAYDEX score is actually calculated

PAYDEX is a weighted average of your payment performance across every trade experience Dun & Bradstreet has on file, translated onto a 1-100 scale. Each trade experience records what you owed, when it was due, and when you actually paid. D&B converts the days-to-pay on each account into a score band, then weights each account by its dollar amount so your largest supplier relationships carry the most influence.

The scale is anchored to a simple idea: 80 is paying on time. From there:

• 100 — payments arrive roughly 30 days before the due date (anticipated).
• 90 — about 20 days early.
• 80 — paid on the due date (prompt).
• 70 — about 15 days beyond terms.
• 50 — about 30 days beyond terms.
• 20 and below — 90-plus days beyond terms.

Two things trip owners up. First, the dollar-weighting means you cannot game the score with a pile of tiny net-30 accounts if your big obligations pay late — the large accounts dominate. Second, D&B only counts what is reported. Plenty of vendors, landlords, and utilities never report to D&B, so paying them perfectly does nothing for your PAYDEX. The score reflects your reported track record, not your true payment behavior.

What counts as a good PAYDEX score

The line most partners draw is 80. At 80 you are, by D&B's own definition, paying on time — and that is what a net-terms supplier or a commercial insurer wants to see before they extend credit or set a premium. Scores above 80 signal you pay early and can help you negotiate larger credit lines or better terms.

Keep the score in perspective. PAYDEX governs how suppliers treat you. It is not what a revenue-based or MCA underwriter leans on when deciding whether to advance working capital — those lenders read your bank deposits. A business can hold an 85 PAYDEX and still be short on cash, or have no PAYDEX at all while running strong monthly revenue.

How to build a PAYDEX from zero

Building a score is mechanical once you know the sequence. The bottleneck is always the same: you need vendors who actually report to D&B, and you need time for their billing cycles to produce reported experiences.

1. Get your D-U-N-S Number. It's free from Dun & Bradstreet and is the identifier every trade experience attaches to. No D-U-N-S, no PAYDEX.
2. Open accounts with reporting vendors. Not all suppliers report. Prioritize net-30 accounts with companies known to report to D&B — office suppliers, shipping/packaging vendors, and business supply retailers are common starting points.
3. Use the accounts, then pay early. You need real charges. Small, regular purchases paid before the due date push you toward the 90-100 band, not just to 80.
4. Reach the reporting threshold. D&B generally needs at least two vendors and three-plus experiences before it generates a score.
5. Add larger reported accounts over time. Because scoring is dollar-weighted, a bigger on-time account does more than several small ones.

Realistically this is a multi-month project, not a weekend one. That timeline is fine when you're building long-term supplier credit — but it is the wrong tool if the reason you're reading this is a cash gap you need to close this week.

PAYDEX vs. how working-capital lenders really underwrite

Here's the disconnect owners run into. They spend months chasing an 80 PAYDEX believing it unlocks financing — then discover the funding they need most, revenue-based advances and MCAs, barely look at PAYDEX at all.

Revenue-based and MCA underwriters approve on bank deposits and revenue trends — the actual cash moving through your business — far more than on any trade-credit bureau score. A typical revenue-based marketplace looks for consistent monthly deposits, a business checking account in good standing, and time in business, with personal FICO accepted from around 500 and funding amounts commonly starting near $10,000. Decisions often land in 24 to 48 hours because the file is bank-statement-driven, not bureau-driven. (No legitimate funder ever guarantees approval — anyone who does is a red flag.)

So the two systems answer different questions. PAYDEX answers "do you pay your suppliers on time?" Revenue-based underwriting answers "is enough cash flowing through the business to support a repayment tied to your deposits?" You can build the first over months. The second reads the reality already in your bank account today.

Decision framework: when to lean on PAYDEX, and when not to

Think of PAYDEX as a supplier-relationship asset, not a funding key. It earns its keep in specific situations and wastes your time in others.

Building PAYDEX works best when:

• You buy inventory or materials repeatedly and want to move from prepay to net-30/net-60 terms.
• You bid on commercial or government contracts where buyers pull a D&B report as part of vendor vetting.
• You carry commercial insurance and want stronger standing at renewal.
• You have months of runway and are building creditworthiness deliberately, not fighting a cash crunch.

Don't wait on PAYDEX when:

• You have an immediate cash gap — payroll, a supplier deposit, an equipment repair, a tax bill — and need funds in days.
• Your business is newer than a year and has no reported trade lines yet.
• Your revenue is solid but your PAYDEX is thin or nonexistent, so the trade score understates you.
• The opportunity in front of you (a bulk-inventory discount, a signed contract needing upfront cost) is worth more than the cost of capital to seize it.

In that second bucket, revenue-based funding is usually the faster, more honest fit: it reads the cash already flowing through your account instead of waiting for vendors to report months of history.

A realistic example: two businesses, same revenue

The following figures are illustrative, not quotes.

Both businesses deposit the same revenue, so both can be candidates for revenue-based funding despite very different credit profiles — Business B's missing PAYDEX and lower FICO don't disqualify it, because the underwriter is reading deposits. Business A's 82 PAYDEX, meanwhile, does real work on the supplier side: it can ask for net-60 terms and better limits. The lesson: PAYDEX and working-capital access are separate tracks. Build the score for your supplier relationships; use deposit-based funding for cash timing.

A practical note on structure: revenue-based repayment is tied to your cash flow, typically as a fixed daily or weekly remittance drawn from your account, so the smoother your deposits, the more comfortably the payment sits. Match the funding amount to a real, revenue-producing use, not a wish list.

Common PAYDEX mistakes owners make

• Paying non-reporting vendors and expecting movement. If the vendor doesn't report to D&B, your on-time payments never touch your PAYDEX. Confirm reporting before you count on an account.
• Chasing volume over dollar size. Ten tiny net-30 accounts move the needle less than a couple of larger reported accounts, because scoring is dollar-weighted.
• Treating 80 as a finish line. 80 is "on time." If your suppliers pull reports at renewal, sitting at 90-plus (paying early) gives you negotiating room 80 doesn't.
• Assuming PAYDEX unlocks working capital. It largely governs supplier and insurer treatment, not revenue-based or MCA approval — those hinge on deposits.
• Letting one big account slip. Because large accounts are weighted heavily, a single late payment on your biggest supplier can drag the score down for multiple reporting cycles.
• Waiting on the score during a cash crunch. Building PAYDEX takes months; a payroll or inventory gap won't. Separate the long-term credit project from the short-term cash decision.
