Building Business Credit: A Guide for Small Business Owners

A business credit profile lets suppliers, lenders and some customers judge your company on its own record rather than only on your personal finances. This guide explains what the three main bureaus measure, the steps that actually create a record, and how your invoicing and payment habits connect to the result. Bureau facts below come from each bureau's own pages, accessed on 27 October 2026. Scoring models change, so check the bureau directly before relying on a specific range.

Last reviewed: 27 October 2026. This is general information for US small businesses, not financial or legal advice. No step here guarantees a particular score, loan or credit limit.

What is a business credit score?

A business credit score is a bureau's summary of how a company pays its obligations and how risky it is to extend credit to it. Unlike consumer credit, there is no single standard score. Each bureau runs its own models on its own data.

Two points from the table matter more than the numbers. First, every bureau scores how you pay others, not how your clients pay you. Second, a score only exists if enough suppliers or lenders report your payments. A business with no reporting accounts may simply have no file.

Experian notes that newer model versions may use different scales, and third-party sites publish conflicting Equifax ranges. That is why this guide quotes only what each bureau publishes itself.

Business credit versus personal credit

If you sign a personal guarantee, you are personally liable for the business debt it covers, so a default can reach your personal finances too. Lenders and card issuers may ask for one; read the guarantee before you sign.

Step 1: Set up the business as its own identity

Bureaus can only build a file on a business they can identify consistently.

1. Form and register the business in your state, if you have not already. Use the same legal name and address on your registration, bank account, supplier applications and invoices.
2. Get an EIN from the IRS. It is free, and the IRS warns that "you never have to pay a fee for an EIN". If the online application is approved, the EIN is issued immediately (IRS: Get an employer identification number).
3. Open a business bank account and keep business payments separate from personal ones. Lenders read bank statements alongside credit reports, and mixed accounts make both harder to read.

Step 2: Get a D-U-N-S Number

Dun & Bradstreet's D-U-N-S Number is "a unique nine-digit identifier used exclusively for businesses". D&B says "there is no cost to request and receive a D-U-N-S Number". Normal processing can take up to 30 business days, and a paid expedited service can deliver it within eight business days (D&B: Get a D-U-N-S Number, accessed 27 October 2026). The free route is enough unless a contract or supplier needs the number urgently.

If a customer's vendor-setup form asks for a D-U-N-S Number, you will already have one.

Step 3: Open supplier accounts that report payments

A PAYDEX score is built from trade experiences that vendors report to D&B. Experian also uses trade payment experiences submitted by payees. That means the accounts that build business credit are the ones where:

• the supplier gives you payment terms (for example, net 30) rather than charging your card at checkout; and
• the supplier reports your payment history to one or more commercial bureaus.

Not every supplier reports, and which ones do can change. Before opening an account to build credit, ask the supplier directly: "Do you report payment history to Dun & Bradstreet, Experian or Equifax?" Then pay those accounts within terms, every time.

The same applies to business credit cards and loans: ask the issuer whether it reports to commercial bureaus, to consumer bureaus, or both. Policies vary by issuer and product.

Step 4: Pay within terms, or earlier

Under D&B's description, a PAYDEX of 80 means reported payments were generally made within terms, and scores above 80 mean payments were made earlier than terms. Paying a net-30 bill on day 40 is 10 days beyond terms, and that is the kind of record that pulls a payment score down.

Practical habits that keep payables within terms:

• Record each bill's due date when it arrives, not when you sit down to pay.
• Pay on a fixed day each week, covering everything due in the next seven days.
• Ask for terms that match your cash cycle. If your clients pay on net 30, a supplier on net 15 will always be paid before you are.
• If you will be late, call before the due date. A supplier may agree new terms. An agreed extension is better than an unexplained late payment.

How your invoicing affects your business credit

Your invoices to clients do not appear on your business credit report. Your clients' payments to you are not your trade experiences, so they do not feed your PAYDEX. The link is cash: if clients pay you late, you are more likely to pay your suppliers late, and those late payments are what the bureaus see.

Worked example (hypothetical figures). A small studio invoices a client $12,000 on Thursday 1 October 2026, net 30. On Monday 5 October a print supplier bills the studio $3,000, net 15, due Tuesday 20 October. The studio has $1,800 spare cash on 20 October.

Nothing about the studio's work changed between the two columns. The only difference is a billing decision. Invoicing habits that protect the cash you need to pay suppliers on time:

• Invoice the day work is delivered, not at month-end. See when to send an invoice.
• Ask new clients for a deposit on large jobs. The deposit invoicing guide shows how to bill it.
• Use payment terms that match your own bills. Net 30 and its alternatives compares the options.
• Follow up the day after the due date, and keep going on a schedule. How to handle unpaid invoices covers each step.
• Know your cash gap before you accept long terms. Small business cash flow explains how to plan it.

Some customers and suppliers also check your business credit before offering you terms or a contract, so a clean payment record helps on the sales side too.

Step 5: Check your reports and dispute errors

Look at what each bureau holds on your business at least once a year, and before any large application:

• Dun & Bradstreet: search for your company and review the D-U-N-S profile on D&B's site.
• Experian: its small-business page offers a business search and a paid CreditScore report ($59.95 as of October 2026).
• Equifax: contact Equifax's small business team for your commercial report.

Check the legal name, address, industry, years in business and every reported trade line. If something is wrong, use the bureau's own dispute or update process and keep copies of your evidence, such as a supplier's statement showing on-time payment.

Step 6: Borrow for a purpose, not to build a score

Credit lines and cards can help with timing, but they cost money if you carry a balance, and they do not fix a business that loses money. Before you apply:

• Know what lenders will also look at. The US Small Business Administration says businesses must normally meet SBA size standards, "be able to repay" and have a sound business purpose, and that the lender provides the full list of eligibility requirements.
• Keep clean financial records: bank statements, tax returns and a list of outstanding receivables. A lender may also ask for a list showing who owes you what and how long they usually take to pay.
• Compare alternatives. If your problem is slow-paying clients rather than a funding gap, invoice financing and factoring or better collection may be a closer fit than new debt.

When this guide is not the right fit

• You are outside the US. Commercial credit bureaus, identifiers and scores differ by country. Check the bureaus that operate where your business is registered.
• You need financing now. A new business credit file takes time to build, because PAYDEX alone looks at 24 months of trade experiences. If you need funds this month, talk to your bank about what it can offer on your current record.
• Your business has missed payments or is in dispute with creditors. Speak to an accountant or a nonprofit business advisor (for example, an SBA-affiliated counselling service) before applying for more credit.

What InvoiceQuickly does and does not do here

InvoiceQuickly does not report to any credit bureau, does not check or monitor business credit, does not offer financing, and does not track the bills you owe suppliers. It focuses on outgoing invoices, which is the cash side of this guide:

• Create invoices from the editor or an AI draft you review before saving, with your legal business name, payment terms (default 30 days, adjustable) and a PO number in the notes.
• Record full or partial payments on every plan and see your outstanding total on the dashboard.
• On Pro ($9/month), email invoices, schedule reminders before and after the due date, and add a payment link through your own Stripe or PayPal account.
• There is no deposit field: bill a deposit as its own invoice and reference it on the final one.

The Free plan covers 5 invoices and 5 clients. See pricing for the full comparison, and the deposit invoice template for a layout.

Frequently asked questions

What is a good PAYDEX score?

Dun & Bradstreet says a PAYDEX of 80 means payments reported to it were generally made within terms, and a score above 80 means payments were made earlier than terms. The scale runs from 0 to 100, based on 24 months of vendor-reported trade experiences.

Is a D-U-N-S Number free?

Yes. D&B says there is no cost to request and receive one. Normal processing can take up to 30 business days. Expedited service, for a fee, can deliver it within eight business days.

Can I use my EIN to get a business credit card?

Many business card applications ask for your EIN. Issuers may also ask for the owner's personal details and a personal guarantee. Ask the issuer whether the card reports to commercial bureaus if building business credit is your goal.

Do late-paying clients hurt my business credit score?

Not directly. Bureau scores are built from how your business pays its own suppliers and lenders. Late-paying clients hurt indirectly, if their delays make you pay your suppliers late.

How do I check my business credit report?

Search for your business on Dun & Bradstreet's and Experian's sites, and contact Equifax's small business team. Experian sells a business CreditScore report for $59.95 (October 2026). Review each trade line and dispute errors through the bureau's own process.

How long does it take to build business credit?

There is no fixed timeline. A score needs enough reporting accounts and enough payment history, and PAYDEX looks at up to 24 months of trade experiences. Opening reporting supplier accounts early and paying them within terms is the main lever.

Does InvoiceQuickly report my payments to credit bureaus?

No. InvoiceQuickly does not report to, or receive data from, any credit bureau. It helps you invoice and collect, which supports the cash you need to pay your own suppliers on time.
