A business credit file does not appear because you registered a company. It appears the first time a supplier reports that you paid an invoice, and not a day sooner.
That single fact is most of the answer to how to start business credit. Everything before the first reported invoice is paperwork that makes reporting possible: the entity, the tax ID, the bank account, the D-U-N-S number. Everything after it is repetition.
For a bakery, florist, caterer or wholesaler that runs its own vans, the stakes are specific. The things you need credit for are the things that keep the routes moving: a second van, a refrigerated unit, a fuel card that does not drain the operating account every Friday, packaging bought by the pallet instead of the case. Those are the purchases that get declined when the business has no file of its own, and they are the ones that force owners to put a van on a personal card.
This guide walks the whole sequence in order, with the timeline you should actually expect and the vendor accounts that make sense when a large share of your costs leave the building on a truck. Once a file exists, the next question is what it qualifies you for, and that comes down to the business line of credit requirements lenders apply to a revolving line.
Key Takeaways
- Business credit starts with a reporting trade line, not an incorporation certificate. Dun & Bradstreet will not calculate a PAYDEX score until at least three vendors have reported payment data.
- The paperwork sequence is entity, EIN, business bank account, D-U-N-S number, then three to five net-30 accounts with vendors that report.
- First trade lines usually surface 30 to 60 days after a paid invoice, and a measurable profile takes 6 to 12 months of consistent payments.
- A PAYDEX of 80 means you paid exactly on the due date. Scores above 80 are reserved for businesses that pay early, which is a deliberate choice, not an accident.
- Under roughly $500,000, most lenders still pull your personal credit and ask for a personal guarantee, so a business file supplements your personal score rather than replacing it.
- For a delivery-driven business, the accounts worth opening first are the ones you already spend on every week: packaging, fuel, tires and parts, and cold-chain supplies.

What business credit is, and why your personal score still shows up
Business credit is a payment-history file held under your company’s identity — its legal name, address, EIN and D-U-N-S number — rather than your Social Security number. Three bureaus maintain these files: Dun & Bradstreet, Experian Business and Equifax Business.
The mechanics differ from consumer credit in two ways that matter. First, there is no automatic enrollment. Your personal file was created the moment a lender pulled your SSN; your business file only exists once a vendor or lender chooses to report to a business bureau, and many do not. Second, anyone can look at it. Business credit reports are not protected the way consumer reports are, which is why a supplier can price your terms before you have ever spoken to them.
Trade credit runs in both directions, and that is worth understanding early. The net-30 terms you receive from a packaging supplier are the same instrument you might extend to a restaurant that buys from you weekly. The decision to offer customer financing to your own buyers is the mirror image of asking a vendor for terms, with the default risk pointed at you instead.
One expectation to set now: building a business file does not get you out from under your personal score. Below roughly $500,000, lenders underwrite the owner, pull a personal FICO, and require a personal guarantee. A strong business file widens the set of lenders that will talk to you and improves the terms suppliers offer. It does not make your personal credit irrelevant.
The seven steps to start business credit from scratch
In order, because each step depends on the one before it. Steps one through four are a few hours of administration spread over a couple of weeks. Step five is where the credit file actually begins.
1. Register the business as a separate legal entity
An LLC or corporation creates the legal separation a separate credit file depends on. A sole proprietorship has no identity apart from yours, so there is nothing for a bureau to open a file on.
Pick the name carefully and then never vary it. This is the step where a brand-new operation, someone working through how to start an ice cream business from scratch, say, sets up either a clean credit identity or a mess that takes a year to untangle.
Use one exact legal name and one exact address everywhere: the state registration, the IRS, the bank, every vendor application. Bureaus match records on these strings. A business filed as “Hartley Bakery LLC” that applies to vendors as “Hartley’s Bakery” can end up with two thin files instead of one usable one, and thin files are the most common reason an owner concludes business credit “didn’t work.”
2. Get an EIN from the IRS
The EIN is your business’s tax ID and the number vendors and lenders use to pull your business file. It is free, the application is on the IRS website, and the number is issued immediately during the online session.
You need it to open a business bank account, file business taxes, and apply for credit in the company’s name rather than yours.
3. Open a business bank account and route every delivery payment through it
Open the account, then stop mixing. Every invoice payment in, every fuel purchase and driver payout out. Bank statements are the primary document underwriters read, and twelve months of clean business-only statements is worth more at application time than almost anything else you can prepare.
This step is where delivery-driven businesses lose the most ground. Route fuel, tolls, parking and vehicle repairs through the business account from the start, even when the personal card is in your hand at the pump. Reconstructing a year of mixed transactions later is miserable, and an underwriter reading commingled statements discounts the whole picture.
4. Get a D-U-N-S number from Dun & Bradstreet
Registering for a D-U-N-S number is free and it enters your company in D&B’s database, which is the precondition for having a PAYDEX score at all. Allow up to 30 business days for the free route; D&B sells faster processing, which is rarely worth paying for if you start the application early.
While you are there, check what D&B already has. Many businesses have a partially populated record built from public data, with the wrong SIC code, an old address or a mangled name, all of which suppress the file’s usefulness until corrected.
5. Open three to five net-30 accounts with vendors that report
This is the step that creates the credit file, and the step most owners skip.
A net-30 account is simply a supplier letting you take delivery now and pay the invoice in 30 days. The credit value comes entirely from whether that supplier reports the payment. Confirm it before you open the account, by asking directly which business bureaus they report to. Plenty of vendors advertise “net-30 terms” and report to nobody.
Open three to five, not one. D&B requires at least three vendors reporting payment data before it will produce a PAYDEX score, so a single account can leave you with a file that still has no score attached after six months of perfect payments.
For a business that delivers its own orders, the natural candidates are the recurring costs you already carry:
- Packaging and shipping supplies: boxes, inserts, labels, void fill, bought by the pallet rather than the case.
- Fuel cards: fleet cards for the vans, several of which report payment data to business bureaus.
- Tires, parts and maintenance accounts: commercial accounts at a tire chain or parts supplier.
- Cold-chain and janitorial supplies: gel packs, liners, insulated totes, cleaning stock for the prep space.
- Office and warehouse consumables: the general-goods suppliers that most explicitly market net-30 terms to new businesses.
The useful trick is to move spending you are already doing onto terms, rather than inventing purchases to build credit. A florist buying $800 of sleeves and boxes a month on a reporting net-30 account builds the same file as one buying $8,000, because PAYDEX weights payment timing rather than dollar volume.
6. Add a business credit card and keep utilization low
Once two or three trade lines are reporting, a business card is the next line to add. It brings revolving history into the file, which trade accounts alone do not provide.
Keep the balance well under the limit. Utilization moves business scores the same way it moves personal ones, and a card run near its ceiling every month reads as strain regardless of whether you pay it off.
7. Pay early, not just on time
Here is the detail that surprises nearly everyone building a file for the first time. On the PAYDEX scale, paying exactly on the due date earns 80. Reaching 90 requires paying about 15 days early, and 100 requires paying 30 or more days early (Chase).
So if a supplier’s terms let you pay at day 10 without penalty, do it. A standing early-payment habit on small invoices is the cheapest way to lift the score your suppliers see.
How long it takes to build business credit
Expect 6 to 12 months before you have a profile a lender will treat as meaningful, and 30 to 60 days before anything appears at all. Most reporting vendors submit payment data monthly, which sets the floor on how fast any of this can move.
A realistic sequence, assuming you open your first reporting accounts in month one:
| Timeframe | What is happening | What you can see |
|---|---|---|
| Days 1–30 | Entity, EIN, bank account, D-U-N-S registration, first net-30 accounts opened and first invoices paid | A D&B record exists; no score yet |
| Days 30–60 | Vendors submit their first monthly reports | First trade lines appear on the file |
| Days 60–120 | Payment activity accumulates across D&B, Experian and Equifax | A PAYDEX score becomes calculable once three vendors report |
| Months 6–12 | Consistent on-time or early payments across multiple accounts | A measurable PAYDEX and Experian Intelliscore Plus |
| Month 12+ | Established profile with depth | Business cards, lines of credit and better supplier terms become realistic |
Claims about building business credit in 30 days are describing the mechanics of a first trade line appearing, not a usable profile. The reporting cadence is monthly and the bureaus want history, so there is no version of this that finishes in a month.
The practical implication for anyone planning equipment purchases: start the file at least a year before you need it. An owner who decides in June that the summer catering season needs a second refrigerated van, and starts building credit in June, is buying that van on personal credit.
What business credit scores mean: PAYDEX, Intelliscore Plus and FICO SBSS
Three scores do most of the work, they run on different scales, and a supplier and a bank are usually looking at different ones.
| Score | Bureau | Range | What drives it | Strong |
|---|---|---|---|---|
| PAYDEX | Dun & Bradstreet | 1–100 | Payment timing only, weighted by dollar amount | 80+ (80 = paid on the due date) |
| Intelliscore Plus | Experian Business | 1–100 | 800+ variables: payment history, balances, utilization, file age, company data | 76+ |
| FICO SBSS | FICO, from blended data | 0–300 | Business and personal credit plus business financials | 155+ for SBA 7(a) prescreen; many banks want 160–180 |
PAYDEX risk bands run 0–49 for high risk, 50–79 moderate, and 80–100 low risk. Intelliscore Plus bands run 1–10 high risk up to 76–100 low risk (Experian).
The distinction worth holding onto: PAYDEX is purely about whether you pay early, on time or late, which is why a small business with modest volume and an early-payment habit can post a strong PAYDEX. SBSS blends in your personal credit and your financials, which is why a clean PAYDEX alone will not carry a bank application.
Where to check your business credit file
Check all three bureaus, because they hold different data and a trade line reporting to one may be missing from the others. D&B’s free Credit Insights gives basic alerts on changes to your PAYDEX. Experian and Equifax sell business reports directly, and several lenders and platforms, Nav and OnDeck among them, offer free business credit summaries pulled from multiple bureaus.
Pulling your own business credit does not damage it. There is no soft-versus-hard distinction on the business side the way there is for consumer credit, so check quarterly while you are building, and before any significant application.
Look for three things specifically: that your legal name and address match your filings exactly, that every vendor you believe is reporting actually appears, and that no trade line shows a late payment you can dispute. A vendor that turns out not to be reporting is worth replacing with one that does, and you will only find out by looking.
What to do with the file once you have one
A credit file is a means to a specific purchase. The two live questions once it exists are what you qualify for and how much you should take.
On qualification, a revolving line is usually the first real target, and it is a different bar from a trade account. Lenders weigh your credit score, annual revenue, time in business and bank-statement consistency, and the thresholds move sharply by lender type. Lines of credit are also among the more attainable products: 46% of applicants for a business line of credit were fully approved in the Federal Reserve’s most recent survey of small employer firms (Federal Reserve Small Business Credit Survey, 2026 report, 6,525 respondents).
On how much, capacity and wisdom are not the same number. A strong file will get you offered more credit than a seasonal, delivery-driven business should carry, and the discipline of sizing debt against cash flow rather than against your approved limit is its own exercise, one worth working through before you draw, using the leverage ratios that define a healthy amount of business debt.
Mistakes that stall a new business credit file
The failures are consistent and nearly all of them are avoidable.
- Opening one trade account and waiting. Below three reporting vendors, D&B will not produce a PAYDEX, so the file sits scoreless while you assume it is building.
- Not confirming who reports. The single highest-value question in this entire process is “which business credit bureaus do you report to?” Ask it before opening any account.
- Name and address drift. Variations across registrations and applications split your history into fragments.
- Running fuel and vehicle costs on personal cards. For a business with routes, this is often the largest single category of spend, and keeping it off the business statements makes the operation look smaller than it is to every underwriter who reads them.
- Paying on the due date and expecting above 80. Due-date payment is an 80. Early payment is the only route higher.
- Letting one invoice slip during a seasonal crunch. PAYDEX weights by dollar amount, so a single large late invoice during the holiday rush moves the score more than several small ones.
- Treating the business file as a replacement for personal credit. Under roughly $500,000, your personal score and a personal guarantee are still in the room.
Frequently Asked Questions
How do I start business credit with no money?
The first four steps cost almost nothing: a state filing fee for the entity, a free EIN, a business bank account, and a free D-U-N-S registration. Net-30 vendor accounts do not require capital either, because you are buying supplies you would purchase anyway and paying for them 30 days later. The real input is 6 to 12 months of consistent payment behavior, not cash.
Can I get business credit with bad personal credit?
You can start a business credit file regardless of your personal score, since net-30 vendor accounts frequently approve on business details alone. What a weak personal score limits is borrowing: below roughly $500,000, most lenders pull your personal credit and require a personal guarantee, so a new business file will not offset a 560 FICO in the near term.
Does an LLC automatically have business credit?
No. Registering an LLC creates the legal entity a credit file can be attached to, but the file itself does not exist until a vendor or lender reports payment activity under that entity’s name, EIN and D-U-N-S number.
How many net-30 accounts should I open?
Three to five. Three is the floor because Dun & Bradstreet requires payment data from at least three vendors before it will calculate a PAYDEX score. Beyond five, the extra accounts add administrative work without much additional signal.
Do business credit cards build business credit?
Some do and some do not, which makes it worth asking the issuer before applying. Many small business cards report only to consumer bureaus unless the account goes delinquent. A card that reports to business bureaus adds revolving history that trade accounts cannot supply, so confirm the reporting behavior rather than assuming it.
Start the file before you need it
The whole process rewards an early, boring start. Register the entity properly, get the EIN and the D-U-N-S number, run every dollar of fuel and packaging through the business account, and put three to five reporting net-30 accounts underneath it. Then pay those invoices about two weeks early for a year.
Do that and the file is ready when the van, the walk-in or the seasonal inventory buy arrives — rather than being something you start building the week the quote lands on your desk.
