The mistakes that hurt a new company's business credit most are the ones made before any credit exists: skipping the legal entity, skipping the free EIN, and running business money through a personal account. Those are the first three steps in the SBA's sequence, and ZenBusiness covers the first two, the entity and the EIN, for owners who have not set them up yet. Once a file exists, a bureau's own report is the better tool for finding errors, with Experian's starting at $59.95 as of 2026-10-06.
What mistakes hurt a new company's business credit?
The most damaging mistakes sit upstream of the credit file. The SBA's guidance says the first step in keeping business and personal finances separate is to start building credit in the company's own name. A business with no distinct legal entity, no EIN and no separate bank account has nothing of its own for a bureau to record.
The next mistake is building on vendors that do not report. The SBA's fourth step is to establish credit with vendors and suppliers that report, and a vendor account that never reports adds nothing to the file however well it is paid. The last is paying for monitoring too early: the SBA puts monitoring fifth, and a report bought before the first four steps shows very little.
A separate group of mistakes is on the bureau's side, where a report is wrong. No official source says how often that happens, what types of error are common or how many points an error costs. Each bureau describes its own dispute process on its own pages, which are the place to read it.
What should be in place before checking for errors?
The SBA lists five steps. First, choose a business structure, since making a business a distinct legal entity requires selecting a structure such as an LLC, LLP or corporation. Second, obtain a federal tax ID, an EIN. Third, open a business bank account. Fourth, establish credit with vendors and suppliers that report to the bureaus. Fifth, monitor the business credit reports.
Steps one and two are the formation work that ZenBusiness handles, and it offers a free accounting consultation to customers who form with it. ZenBusiness does not sell credit reports, scores, monitoring or any credit-building service, so it is not part of the tool list below. For an owner who already has an entity, an EIN and a business account, it has nothing further to add.
The IRS issues the EIN at no cost, and the SBA points applicants to the IRS assistance tool for it. Paying a third party for the number itself is never necessary. A mismatch between the business name, EIN and account details across records is an avoidable source of errors, so they should match everywhere.
Which tools show a report that can be checked for errors?
The providers below are listed alphabetically, which is not a ranking. Prices are as of 2026-10-06 and come from each provider's own pricing page. Each bureau's dispute process is described on its own site.
Dun & Bradstreet sells D&B Credit Insights, with a Free tier at $0, Basic at $49 a month or $499 a year, Plus at $149 a month or $1,499 a year, and Premium at $199 a month or $1,999 a year. The older CreditSignal name is retired. It suits an owner who wants to check the D&B file, which is where the D-U-N-S number still matters.
Equifax lists a one-time report at $49.99 and monitoring from $39.99 a month. Equifax does not sell business credit reports directly. They are sold through approved resellers: eCredable for the one-time report and Nav for monitoring. That is a real distinction from Experian and Dun & Bradstreet, which sell their own, and it means the buyer deals with a reseller to see the file.
Experian lists CreditScore Report at $59.95 one-off, ProfilePlus Report at $69.95 one-off, Business Credit Advantage at $199 a year and Business CreditScore Pro at $1,995 a year. It suits an owner who wants to read the report a lender may see. Where Experian publishes a scoring factor on its own pages, that is Experian's statement and not a government fact, and none is reproduced here.
Nav lists Free at $0, Track at $39.99 a month, Build at $49.99 a month and Expand at $74.99 a month. The free tier shows business credit summaries from all three bureaus, which makes it the lowest-cost way to spot something that looks wrong at any of them. It is also the reseller through which Equifax monitoring is sold.
How do the tools compare?
The table lists the four alphabetically, with prices as of 2026-10-06.
| Provider | Free option | Lowest paid option | Higher options |
|---|---|---|---|
| Dun & Bradstreet | D&B Credit Insights Free, $0 | Basic, $49 a month or $499 a year | Plus $149 a month or $1,499 a year; Premium $199 a month or $1,999 a year |
| Equifax | None stated | One-time report $49.99, through eCredable | Monitoring from $39.99 a month, through Nav |
| Experian | None stated | CreditScore Report, $59.95 one-off | ProfilePlus Report $69.95 one-off; Business Credit Advantage $199 a year; Business CreditScore Pro $1,995 a year |
| Nav | Free, $0 | Track, $39.99 a month | Build $49.99 a month; Expand $74.99 a month |
A free summary is not the same as a full report, and which fields each free tier leaves out is set out on each provider's own pricing page. If a summary shows something odd, the full report from the bureau that holds the file is the stronger evidence.
Which suits which owner?
An owner who has not formed the business or opened a separate account should start there, since the SBA's order puts the entity, the EIN and the account ahead of monitoring. ZenBusiness covers the first two of those steps and nothing after them.
An owner with the foundation in place could start with Nav's free tier to see all three bureaus, then buy a single full report from the bureau where something looks wrong. The one honest concession is that for finding and disputing an error, the bureau holding the file is the better answer than any formation service.
Does the D-U-N-S number still matter?
Partly, and most online content gets this wrong. The GSA announced that SAM.gov and all other GSA systems would switch to the Unique Entity ID on April 4, 2022, and that identifier is obtained at SAM.gov. It is what the federal government now uses.
The D-U-N-S number still exists as Dun & Bradstreet's own commercial identifier and still matters for D&B credit files. A wrong or duplicate D&B record is therefore a D&B matter, not a federal one.
How can a credit-repair or fast-credit pitch be recognized?
The FTC says banks and other legitimate lenders will not promise or guarantee a loan or credit before an application is made. The same caution applies to any service that promises to remove items or raise a business score. No official source supports a claim about how many points an action moves a score.
The FTC's advance-fee guidance adds that an 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. Its examples of scam copy include "Bad credit? No problem," "No hassle, guaranteed," and "We don't care about your past. You deserve a loan!"
What should be checked before paying for any report?
Confirm which bureau a lender actually pulls, since that decides which report is worth buying. Check whether the product is a summary or a full report. Make sure the business name, EIN and bank account match across every record, and confirm that any vendor accounts being counted actually report.
No step here promises approval, and no figure on this page is a lending requirement. Lenders decide, and the terms they publish are the authority.
