The question every owner eventually asks

When I sat on the lending side, owners would call after a decline and ask one version of the same question: “Which credit bureau did you pull?” They assumed there was one business credit score — a single number, like a personal FICO — and that if they could just see it, they’d understand the decision.

There isn’t one. Your business has multiple credit files held by different companies, each producing its own score on its own scale, built from slightly different data. A lender may pull any one of them — or a blended score that mixes your business and personal credit together. Which one they check depends on the lender, the product, and the dollar amount.

So the honest answer to “which bureau is used most for business credit” is: it depends, but a handful of names come up over and over. This guide walks through each one — what it measures, what its score is called, and when a lender is likely to reach for it — so the next decline (or approval) actually makes sense to you.

The four names that matter

There are three major commercial credit bureaus, plus one scoring model that sits on top of them and shows up constantly in small-business lending. Here’s the lineup:

Business credit bureaus and scores at a glance (illustrative scales)

Bureau / model	Its business score	Rough scale	What it’s built on
Dun & Bradstreet	PAYDEX	1–100*	On-time/early payment to suppliers and vendors
Experian Business	Intelliscore Plus	1–100*	Payment history, credit utilization, public records, age of file
Equifax Business	Business Credit Risk Score (and others)	~101–992*; Equifax issues several commercial scores	Payment behavior, credit limits, age of file, public records
FICO	SBSS (Small Business Scoring Service)	0–300*	A blend of business AND personal credit data

* Illustrative scales — each bureau sets and updates its own ranges; verify against the bureau’s own documentation before treating any number as a target.

A few things to pull out of that table before we go deep on each.

First, these scores don’t share a scale and don’t agree with each other. A strong PAYDEX tells you nothing about your Intelliscore. You have to think of them as separate report cards from separate teachers.

Second, FICO SBSS is the odd one out — it’s not a bureau, it’s a scoring model that pulls data from the bureaus and folds in your personal credit. It’s the one most likely to decide whether a bank or SBA loan moves forward. More on that below.

Third, the exact ranges and cutoffs vary, and I won’t guess at a number a lender wants. Where a threshold matters, I’ll point you to ask the lender directly rather than publish a figure that may be wrong for your situation.

Dun & Bradstreet (PAYDEX): the one vendors check first

If there’s a “most used” bureau for everyday business credit, it’s Dun & Bradstreet — largely because of how vendors and suppliers lean on it.

D&B builds your file around a D-U-N-S number, a unique identifier for your business. Its headline score is the PAYDEX, which is built almost entirely on one thing: whether you pay your suppliers on time. The PAYDEX is calculated primarily from the payment history of trade accounts that suppliers and vendors report to D&B. On a personal FICO, on-time is the gold standard. On the PAYDEX, the model is built to reward suppliers’ best customers — so paying early can actually score higher than paying exactly on the due date. As an illustration of how the scale works, a PAYDEX around 80 reflects paying on the due date, and higher scores reflect paying ahead of terms, up to the top of the scale for paying well early.*

Why does this bureau come up so often? Because suppliers, wholesalers, and vendors offering net-30 terms frequently check D&B before extending you trade credit — and those trade accounts, in turn, report back to D&B. It’s a self-reinforcing loop, and for a lot of small businesses it’s the first commercial credit file that ever has a pulse.

The catch worth knowing: D&B offers paid monitoring and “build your score faster” products on top of the free standard D-U-N-S request. You don’t need the paid tier to have a file — getting the free D-U-N-S number is the foundational step, and the standard request is free; timing varies, so confirm the current turnaround with D&B.

Experian Business (Intelliscore Plus)

Experian runs a personal bureau you already know, but it also maintains a separate business credit file — and you don’t have to apply to start one. Experian builds a business file from third-party data it collects (trade payment data from suppliers that report, plus public records), so a file can come into existence once there’s activity tied to your business, without you signing up for it.

Experian’s main business score is Intelliscore Plus. Unlike the payment-centric PAYDEX, Intelliscore draws on a broader mix: payment history, credit utilization (how much of your available credit you’re using), public records (liens, judgments, bankruptcies), the age of your credit file, and the number of trade lines. Intelliscore Plus runs on a 1–100 scale* and weighs these inputs across many variables. It’s designed to predict the likelihood of serious delinquency, which is exactly what a lender wants to know.

In practice, online lenders and some equipment and trade-credit providers pull Experian Business. If you’ve never thought about your Experian business file, that’s worth fixing — because a lender may be reading it whether or not you’ve ever looked at it.

Equifax Business

Equifax also keeps a commercial file separate from its personal one. Equifax actually issues several business scores rather than a single headline number — commonly a Business Credit Risk Score (predicting serious delinquency, on roughly a 101–992 scale*) and a Business Failure Score (predicting closure due to financial stress) — so “your Equifax business score” can mean more than one thing.

Equifax’s commercial data leans on payment behavior, the credit limits and balances on your accounts, the age of your file, and public records. One quirk worth knowing: Equifax pulls in some financial and public-record data that the others may not weight the same way, so it can tell a different story than D&B or Experian on the same business.

Equifax shows up less often than D&B or Experian in everyday small-business lending in my experience, but it’s a real part of the picture — and like Experian, it can build a file on you without you lifting a finger.

FICO SBSS: the one that quietly decides bank and SBA loans

This is the most important name in the list for anyone applying to a bank or for an SBA loan — and the one most owners have never heard of.

FICO SBSS stands for Small Business Scoring Service. It isn’t a bureau; it’s a FICO scoring model that pulls data from the business bureaus and from your personal credit, blends them (it can also factor in business financials and application data), and produces a single score on a 0–300 scale.*

Why it matters: the SBA long required lenders to use an SBSS score to pre-screen 7(a) small-loan applications, and applications that scored below the SBA’s minimum could be routed to a fuller manual review rather than moving forward on the score alone. The SBA ended that pre-screen mandate effective March 1, 2026, but many lenders are expected to keep using SBSS under their own credit policies. Many traditional banks use SBSS for their own small-business underwriting too.

Here’s the part that frustrates owners: because SBSS folds in your personal credit, your personal score keeps mattering for bank and SBA borrowing even after your business has built its own file. This is exactly why the credit score lenders look for isn’t a single business number — for the products that use SBSS, your personal history is baked right in.

So which bureau is “used most”?

Putting it together, the honest answer has two layers:

• For trade credit and many online lenders: Dun & Bradstreet (PAYDEX) and Experian Business come up most. D&B in particular, because the vendor ecosystem runs on it.
• For banks and SBA loans: FICO SBSS is the gatekeeper — and through it, your personal credit stays in play.

There is no single “most used” bureau that applies to every lender. The practical move isn’t to obsess over one score — it’s to ask each lender which bureau they pull before you apply, so you’re not optimizing the wrong report card. A lender that pulls Experian doesn’t care about your PAYDEX, and vice versa.

What every version of this has in common: on-time (ideally early) payments and a clean public record help all of them. You can’t game four scores at once, but you can pay well and stay clean, which moves all of them in the right direction. The mechanics of getting these files started are covered in how to build business credit.

How this connects to getting a line of credit

Knowing the bureaus is useful, but for most owners it leads to a practical question: given my files, which lenders might actually approve me — without my running ten separate applications and collecting ten hard inquiries?

That’s the real risk of shopping bureau-by-bureau and lender-by-lender. Different lenders pull different bureaus and set different cutoffs, so applying one at a time means a string of hard pulls with no way to compare offers side by side.

A lending marketplace solves the matching problem: you submit one application and get matched to multiple lenders, so you see real offers across lenders that pull different bureaus — without a separate inquiry for each.

We lead with a marketplace because it converts any qualified business and lets you compare instead of guess. If you already know the lender you want, our lender reviews cover them one by one — and our how we evaluate lenders page explains the standard we hold each to.
