A small business has two credit identities, and most lenders read both — but not in the same proportions. Your personal score (a FICO or VantageScore built from your own borrowing history) travels with you as the owner. Your business scores live in separate files at Dun & Bradstreet, Experian Business and Equifax Business, built from how the business itself pays suppliers, lenders and card issuers. Which file decides your application depends almost entirely on which channel you apply to. This page gives the pull table the generic explainers skip, explains what each business number actually measures, and closes out one piece of advice that expired in 2026: the blended SBA score that used to mix the two files together no longer exists.
General information, not financial advice.
The pattern below is channel practice as lenders and marketplaces describe it — not law, and individual lenders vary. Read it as the default expectation for each door.
| Channel | Personal file | Business file | What usually decides |
|---|---|---|---|
| Traditional banks | Pulled on every owner-guarantor | Read where a file exists | Personal credit, cash flow and collateral together |
| SBA lenders | Pulled on all owners of 20% or more — the programme structure requires their unlimited personal guaranty | Business data reviewed alongside | The lender’s own underwriting; see the current SBA credit-score treatment |
| Online term and line-of-credit lenders | Pulled, and used as a stated floor (published floors run roughly 500–680 across lenders) | Secondary, or not read at all | Personal score floor plus bank-statement data |
| Revenue-based and MCA funders | Often a soft pull, or skipped | Rarely decisive | Deposits and card receipts — see bad credit but high revenue |
| Invoice factors | Light or none | The customer’s credit is the file that matters | Whether your customers pay reliably, not whether you do |
| Equipment lenders | Pulled | Read where it exists | Personal score plus the value of the equipment itself |
| Corporate card issuers of the Brex/Ramp type | No personal pull on the standard product | Business financials and cash balances instead | Revenue and cash position — see loans that only check business credit |
Two conclusions follow. First, no strong business file substitutes for a damaged personal one at a bank or SBA lender — the guaranty guarantees the personal pull. Second, the revenue-led channels barely read the personal file at all. Knowing which door reads which file tells you where your repair effort counts.
Business scores are not smaller versions of your personal FICO. Each bureau sells a different number, measuring a different thing, on a different scale:
| Score | Scale | What it measures |
|---|---|---|
| D&B PAYDEX | 1–100 | Supplier and trade payments only, dollar-weighted. 80 means you pay within terms; 90–100 is early; 50–79 runs roughly 15–30 days late; below 50 is 30+ days late |
| Experian Intelliscore Plus (V2) | 1–100 | A blended bureau risk score. 76–100 is low risk, 51–75 low-medium, 26–50 medium, 11–25 medium-high, 1–10 high risk |
| Equifax Payment Index | 0–100 | Payment timeliness only — 90–100 means payments on time, a PAYDEX-style gauge |
| Equifax Business Credit Risk Score | 101–992 | Predicted risk of becoming 90+ days delinquent; higher is safer |
Watch for the version trap: Experian’s newer Intelliscore Plus V3 runs 300–850, not 1–100. Two services quoting different scales are using different rulers — comparing the numbers directly is meaningless. Always name the bureau and the scale first.
One more distinction readers get wrong: an absent score is not a bad score. PAYDEX is built purely from trade reporters. A business whose suppliers don’t report may have no meaningful PAYDEX at all — the file is empty, not damaged. That thin-file problem is a different problem from bad credit, with a different fix.
Business tradelines generally do not appear on your personal credit report, and your personal score is not an input to PAYDEX or the other business scores above. The files stay separate while everything performs. They connect in two situations:
Sole proprietors should read all of this with a caveat: the business file exists, but lenders lean almost entirely on the personal one. There is no separation to build — the two files are, in underwriting practice, one.
Older advice — still repeated in ranking guides in the present tense — says the SBA blends your personal and business credit into one number. That was the FICO Small Business Scoring Service (SBSS): a 0–300 blend of personal credit, business credit and financials, used by SBA lenders as a screen on smaller 7(a) loans. The SBA retired the SBSS screen effective March 1, 2026. SBA lenders now underwrite on their own models, with debt-service-based screens, and no single SBA-blended number exists to optimise.
Treat SBSS as history, not as a live screen: it explains why old articles say “your personal score is inside your business score” — true of that retired model, not of PAYDEX, Intelliscore or the Equifax scores. The practical consequence is that the personal file and the business file are now read separately, which is exactly why knowing which channel reads which file matters more in 2026 than it did before. If your business file is the weak or empty one, the building work lives in how to build business credit.
Do business loans check personal credit? Most do. Banks and SBA lenders pull the personal file of every owner who guarantees — on SBA loans, every owner of 20% or more must give an unlimited personal guaranty, so the personal pull is structural. Revenue-based funders and factors are the exceptions: statements and your customers’ credit decide there, and the personal check is often soft or skipped.
What is a good business credit score? It depends which score you mean. On D&B PAYDEX (1–100), 80 is the on-time benchmark and 90+ means you pay early. On Experian Intelliscore Plus V2 (1–100), 76 and above is the low-risk band. On Equifax’s Credit Risk Score the scale runs 101–992 and higher is safer. Never quote a business score without its bureau and scale — Experian’s newer V3 uses a 300–850 scale that cannot be compared with V2 numbers.
Does business credit affect personal credit? Not while the business pays as agreed — the files are separate, and most business tradelines never appear on a personal report. The connection is the personal guarantee: default on a guaranteed business debt and the damage can cross onto the owner’s personal file and into collections. A few business cards also report to personal bureaus by design, in good months and bad.
Do lenders check business credit or personal credit for an SBA loan? Both, but the personal check is the guaranteed one: every owner of 20% or more signs an unlimited personal guaranty, so their personal credit is pulled on every SBA application. Since March 1, 2026 there is no SBSS blended screen — the lender applies its own model to the personal files, the business data and the cash flow, as set out in the SBA credit-score page.
