Most business owners I talk to find out they have no business credit the hard way. They go to apply for a line of credit, or try to get better payment terms with a supplier, and someone on the other end of the phone tells them their business “has no credit profile.” That moment is frustrating and a little embarrassing, and it’s completely unnecessary, because building business credit isn’t complicated. It just requires doing a handful of unglamorous things in the right order.

You might be wondering whether any of this actually matters if your business is profitable and you’ve been getting by fine. Fair question. Here’s my honest answer: it matters a lot once it matters. Business credit determines whether you can get funding without personally guaranteeing everything, whether you pay deposit premiums with vendors, and whether a bank will even look at you during a rough quarter. I’ve watched solid businesses get caught flat-footed because the owner never separated their financial identity from the company’s. Don’t be that person.

This sounds obvious, but a surprising number of small businesses skip the foundation. Before any credit bureau or lender takes your business seriously, you need to look like a real, separate entity.

That means: a formal business structure (LLC or corporation, not a sole proprietorship operating under your own name), a dedicated business bank account, a business address (even a registered agent address works), a business phone number listed in directory assistance, and a professional email. Not a Gmail.

Then register for a DUNS number through Dun & Bradstreet. It’s free. This is your business’s primary identification number for the Dun & Bradstreet credit file, which is one of the three main commercial credit bureaus alongside Experian Business and Equifax Business. Creditors pull these files. If you don’t have a DUNS number, you effectively don’t exist in their system.

Get your EIN from the IRS if you haven’t already. The IRS small business tax center walks you through it and it takes about ten minutes online. Your EIN is to your business what your Social Security number is to your personal credit profile.

Start With Vendors Who Report to Commercial Bureaus

Here’s what I tell people when they’re starting from zero: don’t go straight to a bank. Go to your vendors.

Certain business suppliers offer what’s called “net 30” accounts. You buy supplies or products, and you have 30 days to pay. When you pay, they report your payment history to the commercial credit bureaus. This is the quietest, least-risky way to start building a credit file.

Uline (shipping and packaging supplies), Quill (office supplies), and Grainger (industrial and safety products) are frequently cited as starter-friendly net 30 vendors. They don’t require an existing credit history to open an account. Buy something small, pay the invoice before it’s due, and let that payment get reported. Do this with two or three vendors consistently for six months and you’ll have an actual business credit profile to show lenders.

The part most people miss: not every vendor reports. Before you open a trade account assuming it’ll build your credit, ask explicitly whether they report to Dun & Bradstreet, Experian Business, or Equifax Business. If they don’t, the account won’t do you much good for credit-building purposes. It’s not a bad account to have, it just won’t move the needle on your file.

Business Credit Cards: Use One, Pay It Right

A business credit card is the most accessible credit product for most early-stage businesses. You can often get one through your existing bank, and many issuers (Capital One Spark, Chase Ink, American Express Business) report to the commercial bureaus. Some also still report to personal bureaus, which is worth knowing before you apply.

My strong opinion here: get one card, use it for recurring business expenses (software subscriptions, supplies, whatever makes sense), and pay the full balance every month. Don’t carry a balance to “build credit faster.” That’s a personal credit myth that doesn’t apply here and will just cost you interest.

Keep utilization below 30% of your credit limit. Credit bureaus, both personal and commercial, view high utilization as a risk signal.

One contrarian take I’ll stand behind: I think people spend too much time optimizing business credit card rewards in the first two years. The sign-up bonus is nice, but your priority should be a card that reports to commercial bureaus and has terms you can actually manage. A $500 cash-back bonus means nothing if you’re carrying a balance at 28% APR.

The Long Game: What Actually Moves Your Business Credit Score

Payment history is the biggest factor. Pay early when you can. On-time is the floor, not the goal.

Your business credit scores work differently from your personal FICO score. The Dun & Bradstreet PAYDEX score, for example, runs from 0 to 100 and is based entirely on how quickly you pay relative to terms. An 80 means you pay on time. Above 80 means you pay early. Lenders like to see 75 or higher before extending meaningful credit.

Length of credit history matters too, which is why you want to open those first vendor accounts and keep them open even after you’ve grown beyond needing them for supplies. Closing old accounts can shorten your average credit history.

SCORE mentorship resources have solid free guides on this if you want a deeper breakdown of how each bureau weighs different factors. It’s genuinely useful material, and the mentors are free.

For anyone who wants to go deeper on the mechanics, Business Credit Decoded and Mike Michalowicz’s Profit First (affiliate link, the site may earn a commission) are both worth reading. Not specifically about credit, but Michalowicz’s framing of business finances changes how you think about cash flow, which affects how you manage trade accounts.

Separate Your Personal Credit Completely

The single most important thing you can do for your business’s long-term financial health is stop using your personal credit for business expenses. I know that sounds simple. It almost never happens automatically.

Open that business checking account if you haven’t. Run all business revenue and expenses through it. Use your business credit card for business purchases. When you need a loan down the road, you want a business that can stand on its own financial record, not one that’s tangled up in your personal tax returns and credit history. The goal is to eventually access funding based on what your business has done, not on your personal credit score.

FAQ

How long does it take to build business credit from scratch?

With consistent effort (active vendor accounts, a business card, on-time payments), you can have a meaningful credit profile in 12 to 18 months. The bureaus need payment history to report, and that takes time to accumulate.

Does my personal credit affect my business credit?

Early on, yes. Many lenders and even some vendor accounts will do a personal credit check when your business has no history. As your business credit file grows, you can often qualify for products based on the business profile alone. This is worth working toward.

Can I build business credit with an LLC?

Yes, and an LLC is actually one of the better structures for this because it clearly separates the business as its own legal entity. The structure alone doesn’t build credit, but it sets up the separation that makes it possible.

Do all business credit cards build business credit?

No, and this catches people off guard. Some business cards report only to personal credit bureaus. If building a commercial credit profile is your goal, confirm before applying that the card reports to Dun & Bradstreet, Experian Business, or Equifax Business.

Should I hire a company to build my business credit for me?

I’d be careful here. There are legitimate credit consultants and CPAs who can help, and I’d always recommend consulting a CPA for decisions that touch your business finances. But the “business credit building” industry has a lot of overpriced services for things you can do yourself for free. Start with the foundation steps above before paying anyone to do it for you.
