Building business credit typically takes about a month of setup, two to three months to a first score, three to six months to reach Tier 2 accounts, six to twelve months for business credit cards, and a year or more for lines of credit. These are typical ranges, not promises. The reason is built in: Dun & Bradstreet will not calculate a PAYDEX score until it has at least three payment experiences from at least two different suppliers, and those experiences come from bills you have already paid, reported on each vendor's own schedule.
If anyone promises business credit in 30 days, do the math against that rule.
What "built" means
"Built" is not one moment. It is five milestones:
- Your business has a file at the bureaus.
- Your file has a score.
- You are approved for store and fleet accounts.
- You are approved for business credit cards.
- Eventually, you qualify for lines of credit and larger loans.
Each has its own timeline, and you cannot skip rungs by wanting to.
Weeks 0 to 4: foundation
The first month is setup, and nothing in it produces a score. You form your LLC or corporation with your state, get your EIN from the IRS for free, open a business bank account, set up a business phone number, and make your name, address, and phone identical everywhere. Then you get your D-U-N-S number from Dun & Bradstreet.
The free DUNS route is not always instant, so start it early and check D&B's site for current processing times. Be wary of any upsell that implies you must pay to build credit. You do not. This phase is fully in your control, and most people can finish it in two to four weeks if they work in order. See LLC setup for business credit.
Months 1 to 3: Tier 1
Next you open three to five net 30 accounts with suppliers that report to the business bureaus. Confirm reporting with each vendor before you rely on it. Buy things your business actually needs. PAYDEX is dollar-weighted, so larger payments carry more weight, and paying early scores higher than paying exactly on time.
This phase takes time because of the chain of steps. You place an order, receive an invoice, and pay it. The vendor then reports the payment on its own schedule, and the bureau updates your file. Each step can take days to weeks. For most businesses working at it consistently, a first PAYDEX score typically appears in the 60 to 90 day range. It can be faster or slower depending on how quickly your vendors report.
A sample first 90 days
This is an illustration for a typical new business, not a promise.
- Days 1 to 14: Entity, EIN, bank account, phone, D-U-N-S application, and matching listings.
- Around day 15: Open three vendor accounts and place a first order you actually need from each.
- Pay each invoice as soon as it arrives, not on day 30.
- Around days 30 to 45: Place a second order with each vendor and check whether anything has appeared on your D&B file.
- Days 60 to 90: For many businesses, enough experiences have been reported for a first PAYDEX.
Experian and Equifax move on their own clocks. Your Experian Intelliscore generally appears once vendors or creditors that report to Experian have reported your account, which is why vendor choice matters. See net 30 vendors that report.
Months 3 to 6: Tier 2
Once your Tier 1 accounts are showing on your reports, not just open but reporting, you can start adding Tier 2 accounts: store business accounts and fuel or fleet cards, which generally want to see some payment history first. Add them one at a time, keep using your Tier 1 accounts, and keep paying early. See Tier 2 business credit accounts.
Months 6 to 12: cards
Around six months in, with several accounts reporting and a healthy score, many businesses begin to qualify for business credit cards. Choose cards that report to the business bureaus, because some report only to your personal credit and some report only if you are late. Expect most cards at this stage to still ask for a personal guarantee. Cards without one usually take more business history, revenue, or cash in the bank. See business credit cards with no personal guarantee.
Month 12 and beyond: lines of credit
Business lines of credit and larger loans typically come after the first year. That is not only because of your score. Many lenders set minimums for time in business and revenue, and those are driven by the calendar. No amount of effort makes a six-month-old company two years old. SBA-backed loans usually sit even further out for most new businesses, because lenders want to see an operating history. See business line of credit with no revenue.
What speeds it up and what slows it down
Speeds it up
- Paying early instead of on time
- Using more vendors that actually report
- Keeping your identity details identical everywhere
- Using your accounts regularly, since recent activity counts more
Slows it down
- Opening accounts that never report
- Name or address mismatches that stop bureaus from matching payments to your file
- Even one late payment on a large invoice, since the score is dollar-weighted
- Applying for cards or credit lines too early, which piles up denials and inquiries
One thing to avoid entirely: anyone selling an aged shelf company or rented tradelines as a shortcut. It is not a shortcut. See shelf corporations and business credit.
The realistic version
About a month of setup, two to three months to a first score, three to six months to Tier 2, six to twelve months to cards, and a year or more for lines of credit. It is slower than the ads say, but it is predictable, and you control almost all of it.
