Neither comes first. The SBA's order for building business credit starts with a distinct legal entity, a free EIN and a business bank account, and only then vendor accounts, so anyone who has not done those three should start there, and ZenBusiness covers the entity and EIN steps. Once those are in place, a net-30 account suits a business that buys from suppliers on invoice, while a secured card suits one that needs a card and can put up a deposit. Either one only helps credit if the vendor or issuer reports to a bureau.

Should a net-30 account or a secured business card come first?

Neither, if the business has not yet been set up the way the SBA describes. Its five steps run in order: choose a business structure, get an EIN, open a business bank account, establish credit with vendors and suppliers who report, then monitor the business credit reports. A card and a vendor account both belong after the first three.

The original question people ask is whether to get a business card or a line of credit first for managing cash flow. This page covers the two entry-level routes on this site's lane, a net-30 vendor account and a secured card. A line of credit is a lender product, and the SBA's 7(a) loan program is the official place to read about lender-backed financing.

After the first three steps, the choice depends on what the business actually needs. A business that buys inventory or supplies on invoice has a natural use for net-30 terms. A business that needs to pay for things a vendor would not invoice, such as software or travel, needs a card.

What does each one actually do for cash flow?

A net-30 account is a supplier agreeing to be paid 30 days after the invoice. That gives the business a month between receiving goods and paying for them. It does nothing for purchases the supplier does not sell.

A secured card works differently. The issuer holds a deposit as collateral and the business spends on the card. Deposit amounts, limits, fees and interest are set by each issuer and stated in its own card terms.

For cash flow, the net-30 account stretches payment on one supplier's goods. The card gives general purchasing power up to its limit. They solve different problems, and a business can reasonably use both.

Do either of them build business credit?

Only if the other party reports. The SBA's fourth step is specifically about vendors and suppliers who report, not vendors in general. A payment history that never reaches a bureau builds nothing, however punctual it is.

The same logic applies to a card. Whether a particular issuer reports business card activity to Dun & Bradstreet, Equifax or Experian is set by that issuer. A business should ask before relying on it.

No official source publishes how long reporting takes to show up, how many points any account adds, or what score a lender expects to see. Pages that state those numbers are quoting a proprietary model or guessing.

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 of these 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. Its place 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." A vendor account or a card 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 issuers 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 the vendor route 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 net-30 accounts and secured cards. 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 deposit held as collateral under an issuer's written terms is a different arrangement from a fee paid to be approved, and the issuer's own agreement is where the difference is spelled out. If an offer cannot say what is delivered for the money, the FTC's guidance applies.

What is the sensible order?

Form the entity, get the free EIN, and open a business bank account. Then pick the route that matches the purchases the business actually makes: a net-30 account for supplier invoices, a secured card for everything else, or both.

After a few billing cycles, check the bureau files, whether through a bureau directly or a free tier that summarises all three. That is step five in the SBA sequence, and it is how a business learns whether a vendor or issuer was reporting. If an account never appears, it was a payment arrangement and not a credit-building one.
