Business credit is a separate profile tied to your company's Employer Identification Number, not your Social Security number, and it is built by opening identifiable, reporting tradelines and paying them on time. The process runs on months, not days, because scores move as payment history accumulates and gets reported. The timeline depends on which accounts report to which business credit bureaus.

What is business credit and how is it different from personal credit?
Business credit is a profile that characterizes a company's credit history and its ability to borrow, and it drives access to credit cards, lines of credit, and loans, according to Bank of America. The profile is tied to the business entity and its Employer Identification Number, not the owner's Social Security number, which is what allows it to be built and tracked separately, according to Brex.
The three major business credit bureaus are Dun & Bradstreet, Experian Business, and Equifax Business, according to Brex. Many business credit cards still hold the individual cardholder responsible for payment, so those transactions may not build the company's profile at all, according to Dun & Bradstreet. This article is general information, not tax advice for a specific situation.
What do I need in place before any credit account will report?
An Employer Identification Number is the primary identifier for a business credit profile across all three major bureaus, and the online application takes about 15 minutes with the number issued immediately, according to Brex. The EIN is also used on company tax returns, to open a business bank account, and to apply for licenses, permits, and business credit, according to the US Chamber of Commerce.
A D-U-N-S number is a free nine-digit identifier from Dun & Bradstreet that lets the agency track the business's credit score, and it can be applied for on the Dun & Bradstreet website, according to Bank of America and the US Chamber of Commerce. You usually do not need to apply separately to the other major bureaus for them to track the profile, according to Bank of America. Government contractors and large corporations often require a D-U-N-S number before they will work with a business, according to Brex.
Which accounts actually build business credit?
Trade lines are the foundation of a business credit profile: buy supplies or services on credit from vendors and suppliers and pay the invoices on time, according to First Bank and Ameris Bank. Some national suppliers, including Grainger, Quill, and Uline, often approve new businesses and report payment history to the business bureaus, according to Brex.
Small business lending products that can appear on the profile include lines of credit, business credit cards, term loans, commercial real estate loans, and letters of credit, according to Bank of America. The test for any account is whether it reports to a business bureau and whether it is in the company's name rather than the owner's, according to Dun & Bradstreet.
How long does it take to build business credit?
There is no 30-day path to a strong profile; scores move as payment history accumulates and is reported, and payment history is weighted heavily, according to Brex. A single late payment can significantly affect a business credit score, which is why sequencing new accounts matters more than opening many at once.
Dun & Bradstreet's PAYDEX score runs from 1 to 100; paying vendors on time can reach up to 80, and reaching 100 requires paying early, according to the US Chamber of Commerce. Keep the percentage of available credit used at 30% or less, because high utilization lowers the score, according to Bank of America. Timelines vary by bureau and by how many of your vendors report, so treat any fixed number of days as a planning assumption, not a promise.
Can I build business credit without using my personal credit?
It depends. Loan eligibility for new ventures is often based on the owner's personal credit score, per the Small Business Administration, so a fully separated profile is a goal rather than a starting condition, according to the US Chamber of Commerce. The separation comes from structure: business credit is tied to the entity and EIN, so accounts opened in the company's name build the company's file, according to Brex.
Watch for cards where the individual cardholder remains responsible for payments, since those may not boost the company's score, according to Dun & Bradstreet. Vendor tradelines that report to the business bureaus are the most direct way to add history that is not the owner's personal file, according to Brex and First Bank.
How does multi-state sales tax exposure affect a business credit profile?
Once a business has nexus in more than one state, unfiled sales tax returns become a liability on the books, and that liability sits alongside the credit profile when a lender or vendor looks at the company. Sales tax obligations generally are not reported to the business credit bureaus the way a trade line is, so a clean-looking profile can still sit on top of a real exposure.
Spencer Accounting Group handles multi-state sales tax resolution, including nexus review, exposure quantification, voluntary disclosure, and getting current with each state, through Sales Tax Resolution. For owners who are behind on returns, Back Tax Return Filing sequences the catch-up work to reach compliance with the least disruption. Filing deadlines shift year to year and should be confirmed for the current tax year before you rely on any date.
What mistakes slow business credit down the most?
Opening accounts that do not report to any business bureau produces activity but no profile, according to Dun & Bradstreet and Brex. Using personal cards for company purchases and assuming the company's score is benefiting is another common error, according to Dun & Bradstreet.
Running high balances relative to the limit also slows progress; keep utilization at 30% or less, according to Bank of America. Missing a single vendor payment carries outsized weight in business credit scoring, according to Brex. Skipping the EIN or D-U-N-S setup means nothing is being tracked at all.
