Trade credit from net-30 vendors can help a new business file, but only when the vendor reports its payment history to a bureau, and revolving credit has the same condition. The SBA's order puts a distinct legal entity, a free EIN and a business bank account ahead of either one, so anyone who has not done those three should start there, and ZenBusiness covers the entity and EIN steps. After that, trade credit suits a business that buys from suppliers on invoice, while revolving credit suits one that needs flexible purchasing power.

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 a supplier agreeing to be paid within 30 days of an invoice. That arrangement only becomes a credit-building account if the payment history reaches a bureau and lands on the business's file.

The SBA's wording is specific. Its fourth step is to establish credit with vendors and suppliers who report, not with vendors in general. That distinction separates an account that builds a file from one that is only a payment-terms agreement.

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. Any page that states those numbers is quoting a proprietary model or guessing.

What is the difference between trade credit and revolving credit?

Trade credit is a supplier extending payment terms on goods or services it sells. The business gets a month between receiving an invoice and paying it, and the arrangement covers only that supplier's products.

Revolving credit is a lender extending a limit that can be used, repaid and used again, such as a card or a line of credit. It is not tied to one supplier's goods. Limits, fees, interest and reporting practices are set by each lender and stated in its own terms.

For a new file, the two differ mainly in who is doing the reporting. A supplier may or may not report to a bureau, and a lender may or may not report to the bureaus a business cares about. In both cases, reporting is a fact about that particular company and should be confirmed.

Business credit cards have their own coverage on a sibling site, so this page does not compare specific cards. The SBA's 7(a) loan program is the official place to read about lender-backed financing.

Which should come first for a new file?

Neither, if the business has not yet been set up the way the SBA describes. The SBA's five steps run in order: choose a business structure, obtain an EIN, open a business bank account, establish credit with vendors and suppliers who report, then monitor the business credit reports. Both routes sit after the first three.

Once those are in place, the choice depends on what the business buys. A business that purchases inventory or supplies on invoice has a natural use for net-30 terms. A business that needs to pay for things suppliers would not invoice has a use for revolving credit.

Many businesses use both, and no official source ranks one ahead of the other for building a file.

Where do the entity and bookkeeping steps fit?

Steps one and two of the SBA sequence, the legal entity and the EIN, come before both routes. The SBA says a business becomes a distinct legal entity by selecting a structure such as an LLC, LLP or corporation, and that the EIN can be applied for free through the IRS assistance tool. 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 a credit card, a line of credit, credit monitoring or a credit-building service. It is not a competitor to either route in this comparison, and its role here is limited to the first steps the SBA lists.

The SBA frames 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." Trade or revolving credit opened before that separation exists has nothing in the company's name to attach to.

How can a business see which bureau holds what?

Whichever route a business takes, the result either appears in a bureau file or it does not. 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 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 and lenders 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.

This matters for trade credit in particular, because some vendors and guides talk about a D-U-N-S number as if it were a requirement for credit. For a D&B file it is relevant, and for federal systems it is not.

What should a fast-credit offer never ask for?

Packages that promise quick business credit are the most common false shortcut, and they tend to appear around both vendor accounts and revolving credit. 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 either route is working?

After a few billing cycles, open the business's files at Dun & Bradstreet, Equifax and Experian, or use a free tier that summarises all three. Look for the vendor or lender among the 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 other steps verifiable. If an account never appears on any file, it was a payment arrangement and not a credit-building one. The vendor or lender can then be asked which bureau it reports to and whether reporting has to be requested.
