Building business credit is not complicated, but it is slow. The business owners who succeed at it are not the ones who found a shortcut. They are the ones who took the right steps in the right order and stayed consistent for 12 to 18 months while their profile seasoned. This guide gives you a month-by-month timeline so you know exactly what to do and when to do it.

Before diving in, understand the foundation: business credit bureaus like Dun and Bradstreet, Experian Business, and Equifax Small Business track your business separately from you as an individual. To build a strong profile with them, your business needs to look like a real, established entity. That process starts before you ever apply for a credit account. If you have not yet read our explainer on what a business credit score is and how it works, start there before following this timeline.

Month 1: Build the Legal Foundation

Nothing you do in Month 2 or beyond will work properly if your business is not set up as a separate legal entity with its own identity. This month is about creating that foundation.

Form Your LLC or Corporation

A sole proprietorship is not a separate legal entity. It is you doing business under your own name. Lenders and vendors who pull business credit want to see a business that is legally distinct from the owner. Form an LLC or corporation in your state. The filing fee varies by state, typically between 0 and 00. Use a registered agent service to maintain a clean business address.

Get Your EIN

An Employer Identification Number is the business equivalent of a Social Security Number. You need it to open a business bank account, apply for business credit, and hire employees. Applying is free and takes about 10 minutes on the IRS website. Our detailed guide on getting your EIN walks through the full process. Do not skip this step. Every credit application you fill out will ask for your EIN.

Open a Dedicated Business Checking Account

Open a business checking account in your company’s legal name, using your EIN. Use it exclusively for business income and expenses. Never mix personal and business funds. Banks report business account history to credit bureaus in some cases, and more importantly, having a separate business account is a prerequisite for vendor accounts and business credit cards.

Month 2: Register with the Credit Bureaus

Business credit bureaus do not automatically know your business exists. You need to register so they can start tracking your activity.

Get Your D-U-N-S Number from Dun and Bradstreet

A D-U-N-S Number is a free, unique identifier that Dun and Bradstreet assigns to your business. It is the key that unlocks a PAYDEX score. Go to the Dun and Bradstreet website and apply for a free D-U-N-S Number. Standard processing takes about 30 days. An expedited option is available for a fee if you need it faster.

Register with Experian Business

Experian Business may already have some information on your company if it was formed through a state filing. Confirm your business profile exists and is accurate by searching on the Experian Business site. Correct any errors early before they compound.

Set Up Free Monitoring Through Nav

Nav is a free platform that aggregates your business credit data from multiple bureaus and gives you a dashboard view of your profile. It is not a bureau itself, but it pulls data from the major bureaus and gives you a way to track your scores over time without paying for each bureau’s premium access. Set this up in Month 2 and check it monthly going forward.

Months 3 and 4: Open Vendor Trade Lines That Report

This is the most important phase for actually building your score. Trade lines are credit accounts with vendors and suppliers who sell to you on net-30 terms and report your payment history to business credit bureaus. The key word is report. Many vendors offer net-30 terms but do not report to bureaus. You need accounts that report.

Target at least 3 of the following vendors:

• Uline: Office and shipping supplies. Offers net-30 accounts and reports to D&B. Order something small, pay the invoice early.
• Quill: Office supplies. Reports to D&B and Experian Business. Easy to get approved as a new business.
• Grainger: Industrial and maintenance supplies. Reports to D&B. Good for businesses in any industry since they sell broadly.
• Crown Office Supplies: Designed specifically for businesses building credit. Reports to all three major bureaus.

The strategy is simple: place a small order (even 0 to 00 worth of supplies you will actually use), pay the invoice at least 5 days before the due date, and repeat. Do this for 2 to 3 months consistently. These early trade lines are what plant the first positive data into your credit profile.

Months 5 and 6: Apply for a Secured Business Credit Card

Once you have 2 to 3 months of positive vendor trade line history, you are ready to apply for your first business credit card. Start with a secured business credit card, which requires a cash deposit that becomes your credit limit. Secured cards are much easier to obtain for new businesses with thin credit files.

Use the card for regular business expenses. Pay the full balance every month before the due date. Never carry a balance if you can avoid it. The goal at this stage is not to maximize credit. It is to build a track record of responsible use that bureaus can see.

According to SBA guidance on building business credit, consistent on-time payment is the single most impactful factor in developing a strong business credit profile.

Months 7 Through 12: Use, Pay, Repeat

This phase is straightforward but requires discipline. Use your vendor accounts and business credit card regularly. Pay every invoice and every statement on time, ideally a few days early. Keep utilization low, below 30% of available credit on revolving accounts.

Check your Nav dashboard monthly. You should start seeing PAYDEX activity by Month 4 or 5 and Experian Intelliscore data building by Month 6 to 8. By Month 12, you should have a measurable profile with at least two of the three major bureaus.

During this period, make sure your business information is consistent across all accounts and registrations. Your business name, address, and phone number should be identical everywhere. Inconsistencies create separate records at the bureaus and dilute your credit history.

Month 13 and Beyond: Scaling Your Credit Profile

After 12 months of consistent positive history, you are ready to apply for more substantial credit products.

Apply for an Unsecured Business Credit Card

With a seasoned credit profile, you should now qualify for an unsecured business credit card from a major bank or credit card issuer. Cards like the Chase Ink Business Cash, American Express Blue Business Cash, or Capital One Spark line are common targets at this stage. Higher credit limits mean more purchasing flexibility and the ability to demonstrate responsible use at scale.

Apply for a Small Business Line of Credit

A business line of credit gives you access to revolving capital you can draw from and repay as needed. It is one of the most flexible financing tools available to small businesses. At this point in your timeline, you should have a D&B PAYDEX score of 75 or higher and a developing Experian Intelliscore, which puts you in a solid position for approval at community banks and online lenders. Our guide on how to qualify for a business line of credit covers what lenders look for in detail.

Realistic Expectations

A fully fundable business credit profile, one that qualifies for significant unsecured financing at competitive rates, takes 12 to 18 months minimum to build from scratch. There are no shortcuts that skip this timeline without using personal credit guarantees, which defeats the purpose.

The businesses that build the strongest profiles fastest are the ones that start immediately when the entity is formed, use vendor accounts consistently rather than in bursts, pay early rather than just on time, and monitor their profile regularly to catch errors before they compound into problems.

Start today. The 12 to 18 month clock does not begin until you take the first step.
