Net-30 vendor accounts can help build business credit, but only when the vendor actually reports payment history to a bureau. The SBA lists "vendors and suppliers who report" as the fourth step, after forming a distinct legal entity, getting an EIN and opening a business bank account. No official source publishes a master list of which vendors report to which bureau, so the dependable check is to pull the business's own reports from Dun & Bradstreet, Equifax and Experian and see which trade accounts appear. Anyone who has not yet formed the entity or separated business and personal money should start there, and Nav's free tier is the lowest-cost way to see all three bureaus in one place.

Do net-30 vendor accounts really help build business credit?

They can, with one condition that decides everything: the vendor has to report. A net-30 account is simply an arrangement to pay an invoice within 30 days. Paying on time is only useful for credit purposes if that payment history reaches a bureau and lands on the business's file.

The SBA's own guidance reflects this wording. Its fourth step is to establish credit with vendors and suppliers who report, not with any vendor at all. That distinction is the whole difference between an account that builds a file and an account that is just a payment terms agreement.

What the official sources do not say matters too. There is no published figure from the SBA for how many points a vendor account adds, how long a file takes to form, or what score a lender needs to see. Any page that states those numbers confidently is either quoting a bureau's proprietary model or guessing.

What order does the SBA put vendor accounts in?

The SBA's five steps to build business credit run in a fixed order. First, choose a business structure, because making the business a distinct legal entity requires selecting a structure such as an LLC, LLP or corporation. Second, obtain a federal tax ID number, the EIN, which can be applied for free through the IRS assistance tool. Third, open a business bank account. Fourth, establish credit with vendors and suppliers who report. Fifth, monitor the business credit reports.

The agency also frames the purpose of the sequence. In its words, "To keep your business and personal finances separate, the first step is to start building credit in your company's name." Vendor accounts only make sense once there is a company name, an EIN and a bank account for the invoices to be paid from.

This is where many guides go wrong. They open with a list of vendors that supposedly report, as if the account itself were the first move. The government's order says the file has to exist in the business's name before a vendor can add to it.

One more point on the EIN: the IRS issues it for free. Paying a third party for one is never necessary.

Which vendors report, and to which bureau?

This is the question in the title, and the honest answer is that no verified roster exists to copy into an article. Which vendors report, to which bureau, and under what conditions is set by each vendor and each bureau. It changes, and the SBA does not publish it.

That is why this page does not name vendors as reliable reporters. A named list would imply a verification that has not happened, and a vendor that reported last year may not report this year. A stale list is worse than none, because someone can spend months paying invoices on an account that never reaches a file.

A practical approach is to confirm before relying on any account. Ask the vendor directly which bureaus it reports to, and whether reporting is automatic or requires a request. Then confirm the result by pulling the reports after a few billing cycles. The bureau reports are the proof, and the vendor's statement is only a claim until they show it.

Where a bureau publishes its own reporting factors or requirements, the bureau's own materials are the place to read them, and they should be treated as that bureau's description of its own product, not as government fact.

Why does the DUNS number confuse so many guides?

Most content on this topic treats the D-U-N-S number as the federal business identifier. That stopped being true on Monday, April 4, 2022, when SAM.gov and all other General Services Administration systems switched to the new Unique Entity ID. The Unique Entity ID is obtained at SAM.gov.

A D-U-N-S number still exists. It is Dun & Bradstreet's own commercial identifier, and it still matters for D&B credit files. So the accurate statement has two halves: the government no longer uses it, and D&B still does.

For a business that wants federal contracts or grants, the Unique Entity ID is the relevant number. For a business that wants a D&B credit file, the D-U-N-S number is relevant. Guides that fold these into one requirement, or tell readers a D-U-N-S number is needed for SAM registration, are repeating pre-2022 information.

Where do the entity and bookkeeping steps fit?

Steps one and two of the SBA sequence, the legal entity and the EIN, sit upstream of any vendor account. For a reader who has not formed a business yet, or who still runs money through a personal account, that is the actual starting point. ZenBusiness is one provider that handles formation and offers a free accounting consultation to customers who form with it, which is why its accounting page is the relevant link for the recordkeeping side of this sequence.

ZenBusiness does not sell a credit product, a credit monitoring service or a credit-building service, and it is not part of the bureau comparison below. Its role here is limited to the first steps the SBA lists.

Clean books also matter later. A business that is paying net-30 invoices on schedule should be able to show those payments in its own records, which makes it easier to spot a payment that a vendor failed to report.

How do the bureau-side options compare?

The four options below are listed alphabetically. The order is not a ranking. All prices were verified on each provider's own pricing page on 2026-10-06 and are stated as of that date, since they change.

Dun & Bradstreet. D&B sells its own credit products, under the current name D&B Credit Insights (the older CreditSignal name has been retired). As of 2026-10-06 the tiers are Free at $0, Basic at $49 per month or $499 per year, Plus at $149 per month or $1,499 per year, and Premium at $199 per month or $1,999 per year. The D-U-N-S number is relevant here because it is D&B's own identifier. Best for a business that specifically wants to see and manage its D&B file.

Equifax. Equifax does not sell business credit reports directly. They are sold through approved resellers: eCredable for the one-time report and Nav for monitoring. As of 2026-10-06 the one-time report is $49.99 and monitoring starts from $39.99 per month. That is a real difference from Experian and Dun & Bradstreet, which sell their own. Best for a business that wants an Equifax view and is comfortable buying through a reseller.

Experian. Experian sells its own reports and subscriptions. As of 2026-10-06 the CreditScore Report is $59.95 as a one-off, the ProfilePlus Report is $69.95 as a one-off, Business Credit Advantage is $199 per year, and Business CreditScore Pro is $1,995 per year. Best for a business that wants a one-time look at an Experian file without a subscription.

Nav. As of 2026-10-06 Nav's tiers are Free at $0, Track at $39.99 per month, Build at $49.99 per month and Expand at $74.99 per month. The free tier shows business credit summaries from all three bureaus. That makes it the lowest-cost way to see whether a vendor's reporting has appeared anywhere. Best for a first look across Dun & Bradstreet, Equifax and Experian before paying for any single bureau's full report.

A note on how to read these prices: they are costs of seeing a file, not costs of building one. Paying for a report does not add anything to a score. The report is a window onto what vendors and lenders have already reported.

What should a net-30 "credit builder" service never ask for?

Some services sell packages that promise fast business credit. The FTC's guidance on advance-fee loans is a useful test. Banks and other legitimate lenders will not promise or guarantee a loan or credit before an application. And any up-front fee collected before the loan is granted is a cue to walk away, especially when it is labelled "insurance," "processing," or "paperwork."

The FTC also lists the language scam ads tend to use, including "Bad credit? No problem," "No hassle, guaranteed," and "We don't care about your past. You deserve a loan!" Guarantees and fees collected before anything is approved are the pattern to watch for.

There is a distinction worth keeping straight. A bureau selling a report at a published price is selling a report, and the price is on the page. A service that charges before anything is delivered, and promises an approval or a score in return, is selling something no legitimate lender or bureau promises.

A reasonable rule for any such service is to ask what, exactly, is delivered for the fee. If the answer is a report or monitoring, the cost can be compared with the prices above. If the answer is a guaranteed result, the FTC's guidance applies.

How can a reader check what a vendor actually reported?

The check is simple and does not need a roster. Open the business's reports at Dun & Bradstreet, Equifax and Experian, or use a free tier that summarises all three. Look for the vendor's name among the trade accounts and compare the payment history shown against the business's own records.

If an account does not appear after several billing cycles, ask the vendor which bureau it reports to and whether reporting has to be requested. If it never appears, it was a payment arrangement and not a credit-building account.

This is also step five in the SBA sequence: monitor the business credit reports. The monitoring is not a separate project from the vendor accounts. It is how the vendor accounts get verified.
