A net-30 vendor account is an arrangement where a supplier delivers goods or services now and the business pays the invoice within 30 days. It helps build business credit only when the vendor reports that payment history to a bureau, and no official source publishes which vendors do. The SBA places vendor accounts fourth in its five steps, after a distinct legal entity, a free EIN and a business bank account, so anyone who has not completed those should start there.

What is a net-30 vendor account?

It is payment terms, not a loan. A supplier ships an order, issues an invoice, and the business has 30 days to pay it. The business gets a month between receiving goods and paying for them, and the supplier takes on the risk that the invoice goes unpaid.

The account covers only that supplier's goods or services. Whether the supplier charges fees, requires an application or sets a limit is decided by the supplier and set out in its own terms.

A net-30 account becomes a credit-building account only under one condition: the supplier sends the payment history to a bureau. Without that, it is a payment arrangement and nothing more.

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

They can, when the vendor reports. The SBA's fourth step is to establish credit with vendors and suppliers who report, not with vendors in general. That wording is the whole difference between an account that builds a file and one that does not.

No official source publishes how many points a vendor account adds, how long a file takes to form, or what score a lender needs to see. Pages that state those figures are quoting a proprietary model or guessing.

Which vendors report to Dun & Bradstreet, Equifax or Experian is set by each vendor and bureau. The only dependable check is to look at the business's own files after a few billing cycles.

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 the SBA says making a business a distinct legal entity requires selecting a structure such as an LLC, LLP or corporation. Second, obtain an EIN, which the SBA says 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 SBA puts the purpose in one line: "To keep your business and personal finances separate, the first step is to start building credit in your company's name." A vendor account opened before that separation exists has nothing in the company's name to attach to.

The IRS issues the EIN at no charge, so any service charging for one is charging for something the agency gives away.

Where do the entity and bookkeeping steps fit?

Steps one and two of the SBA sequence, the legal entity and the EIN, come before any vendor account. ZenBusiness handles formation and offers a free accounting consultation to customers who form with it, and its accounting page covers the recordkeeping side.

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

Clean books help later. A business that pays invoices on schedule can compare its own records with what a bureau shows, which is how a missing or wrong entry gets caught.

How can a business see whether a vendor reports?

Look at the bureau files. The four options below are listed alphabetically, and 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, which replaced the older CreditSignal name. 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. Best for a business that 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. 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 the 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. Best for a first look across all three before paying for any one bureau's full report.

These prices are the cost of seeing a file, not of building one. A report shows what vendors have already reported, and buying one adds nothing to a score.

Why does the DUNS number confuse so many guides?

Many guides still treat the D-U-N-S number as the federal business identifier. That ended on Monday, April 4, 2022, when SAM.gov and all other General Services Administration systems switched to the Unique Entity ID, which is obtained at SAM.gov.

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

Some vendors and guides present a D-U-N-S number as a requirement for any net-30 account. That is a claim about a particular vendor's terms, not a federal rule.

What should a fast-credit service never ask for?

Packages that promise quick business credit through net-30 accounts are a common false shortcut. The FTC's guidance on advance-fee loans offers a usable test. Banks and other legitimate lenders will not promise or guarantee a loan or credit before an application.

The same guidance says any up-front fee collected before a loan is granted is a cue to walk away, especially when it is described as "insurance," "processing," or "paperwork." It also lists phrases common in scam ads, including "Bad credit? No problem," "No hassle, guaranteed," and "We don't care about your past. You deserve a loan!"

The FTC has also published a consumer alert on fraudulent funders targeting small businesses. A bureau selling a report at a published price is selling a report. A service that charges first and promises an approval or a score in return is selling something no legitimate lender or bureau promises.

How can a business tell whether a net-30 account is working?

Open the files at Dun & Bradstreet, Equifax and Experian, or use a free tier that summarises all three. Look for the vendor among the trade accounts and compare the payment history shown with the business's own records.

This is step five of the SBA sequence, and it is what makes the vendor step verifiable. 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 anywhere, it was a payment arrangement and not a credit-building account.
