A strong business credit profile can open doors to better financing, lower interest rates, and higher credit limits. Yet many small business owners don’t realize they can use a business line of credit to help establish or strengthen their company’s credit history. 

A business line of credit provides flexible access to funds for short-term expenses and can also play a key role in showing lenders that your company manages credit responsibly. Of course, it’s important to use your business line of credit wisely—only borrowing what you can afford and making consistent, on-time payments. If you maintain these good habits, you can use your credit line to steadily improve your business credit score over time. The following guide explains how business credit works. Learn how a line of credit can fit into your credit-building goals and the best ways to boost your company’s credit profile over time.

Understanding business credit and lines of credit.

Before you use a line of credit to build your company’s credit profile, it’s important to understand two key details: how business credit works and how a line of credit functions. Many small business owners focus on personal credit when they apply for financing, especially during the startup phase. In fact, a recent survey from the Federal Reserve found that 86% of small employer firms use personal credit to obtain financing.

Yet lenders often evaluate business credit as well when you seek certain types of capital. Working to establish good credit for your business can protect your personal credit and open the door to more funding opportunities for your company.

What is business credit?

Business credit is data that others can use to measure how reliably your company handles its debt and financial obligations. Lenders, suppliers, insurers, and even potential partners may review your business credit profile to perform risk assessments before extending financing or terms to your company. 

Unlike personal credit, business credit has a direct connection to your company’s name and Employer Identification Number (EIN). Some of the most common business credit scores come from developers like Dun & Bradstreet, Experian Business, and Equifax Business.

Business credit scores often weigh factors such as payment history, length of credit history, company size, years in business, and credit utilization. Yet before your business can build a credit score, it must establish credit accounts (often called tradelines) in the company’s name.

A healthy business credit score may help your company:

  • Qualify for lower borrowing costs and better insurance premiums. 
  • Access higher credit limits to support growth.
  • Receive more favorable payment terms from vendors and suppliers.

How a business line of credit works.

A business line of credit is typically a revolving credit account, similar to a business credit card. Your lender approves you for a credit limit, and you draw the amount of money you need to cover cash flow gaps, inventory purchases, unexpected repairs, or other expenses. As your business repays the cash it borrows, the funds become available again to reuse throughout the draw period on your account.

Key features of business credit lines include:

  • Revolving access: Borrow, repay, and reuse your credit line as needed.
  • Variable interest: Line of credit interest rates often track market benchmarks, like the Prime Rate or the Secured Overnight Financing Rate (SOFR).‍
  • Flexible use: Use to cover short-term expenses, seasonal costs, or unexpected repairs.

Why responsible use matters.

Good borrowing habits (like consistently paying your credit line on time), can demonstrate to lenders that your company manages credit responsibly. These behaviors influence your business credit scores and may help you qualify for better rates and terms in the future. When you use it strategically, a business credit line not only can meet your working capital needs, but may also become a stepping stone toward future opportunities.

Steps to building business credit with a line of credit.

Using a business line of credit strategically can strengthen your company’s financial foundation over time. But your results depend on several factors, including how you prepare before you apply and how you manage the account once it’s open. Follow the steps below to give your business the best chance of qualifying for a credit line and using your new account as an effective credit-building tool.

Step 1: Prepare to apply and strengthen your eligibility.

Before you apply for a business line of credit, make sure your business is ready. Lenders typically review your company’s legal status, finances, and credit history before approving new financing applications. Preparing in advance could improve your chances of approval and show lenders that you operate professionally. Key tasks to prepare for your application:

  • Register your business legally. Make sure to register your company as an LLC, corporation, or other legal entity with your state so it can build credit in its own name.
  • Apply for an Employer Identification Number. Obtaining an EIN from the IRS lets lenders and business credit bureaus track your company’s financial activity separately from your personal finances. 
  • Open a business bank account. Maintaining a separate business bank account helps you keep personal and business finances separate. ‍
  • Organize financial documents. Gather essential documents like financial statements, recent tax returns, and cash flow reports for upcoming lender applications.

Step 2: Apply for a business line of credit.

Shop around for lenders that offer credit lines suited to your company’s credit profile, size, and borrowing needs. When you compare financing offers, pay attention to details such as: 

  • APR 
  • Fees (annual, draw, and maintenance)
  • Credit limits
  • Repayment flexibility
  • Qualification requirements (e.g., minimum credit score, time in business, annual revenue, etc.)

Once you choose the credit line that works best for your business, submit a complete application with accurate documentation. Some lenders may require a personal guarantee or collateral if you’re applying for a secured business line of credit. These requirements might be more common if your business is new or has limited credit history.

Tip: Ask lenders if they report to business credit as part of their program. Many lenders do, but some do not. The majority of lenders who offer lines of credit in the Lendio Marketplace report to Experian, Equifax, or Dun & Bradstreet, which can help you build your business credit history!

Step 3: Use the line of credit responsibly.

Treat your business line of credit as a strategic tool rather than an open checkbook. Make a habit of borrowing only what you need for short-term expenses that support business growth. It’s also important to track each draw and manage spending to avoid overutilization. Using a high percentage of your credit limit could increase your credit utilization ratio and might damage your credit score until you pay down the balance on your credit line. When it comes to credit utilization, lower is better.

Step 4: Make on-time, consistent payments.

Your payment history carries the most weight when you’re building business credit. Pay at least the minimum amount due each month. Consistently paying on time (or even early) can help your credit score and save you money on interest charges. If possible, set up automatic payments to reduce the risk of missing a due date. When cash flow allows, making extra payments could lower your debt faster and improve your credit utilization ratio as well.

Optimizing impact on business credit score.

Next, aim to optimize how your credit line is impacting your business credit score. In other words, find out how to make every draw and payment count—not just from a financial point of view, but from a credit-building perspective, too.

Below are a few helpful strategies, business credit score factors, and pitfalls to understand.

Key credit score factors.

Different credit scoring models consider different data when calculating your business credit score. With your PAYDEX® Score, for example, past payment performance determines the score your business earns on a scale of 1 and 100. Other business scoring models may also consider a wider range of details. While business scoring models differ, the following factors commonly carry weight:

Factor Impact Tip
Payment history Often the most signficant drivers in your business credit score. Always pay at least the minimum payment on your credit line, and aim to pay early or on time.
Credit utilization High balances relative to your credit limit signal higher risk. Keep your balance-to-credit limit ratio low to optimize your score. Pay full statement balance by due date to avoid interest charges.
Credit mix A mixture of different trade lines and account types may benefit your overall score. Work with lenders, vendors, and suppliers who report to business credit bureaus.
Credit applications Excessive new financing applications in a short time frame could signal financial instability. Don't be afraid to apply for new credit when your business needs it, but seek new financing strategically.
Derogatory items Collection accounts or public records (like tax liens) are red flags and could damage your credit score. Try to avoid serious delinquencies and resolve negative items quickly if they happen.

By understanding the credit score factors above and working to manage your credit line according to these details, you put yourself in a better position to earn and maintain good business credit over time.

Pitfalls to avoid when using a line of credit.

It’s also important to avoid common mistakes when you open a business line of credit, such as the following.

  • Maxing out your credit line: High utilization could hurt your credit score, even if you pay on time. 
  • Late payments: Any delinquencies (especially missed payments) could cause significant credit score damage. 
  • Neglecting credit reporting: If your lender or vendor doesn’t report your account to the business credit reporting agencies, your positive payment history won’t count. Look for lenders that share data with one or more of the business credit bureaus. 
  • Frequent hard credit inquiries: Applying for too many credit lines in a short period could damage your credit score. So, choose your preferred new account before filling out any financing applications.‍
  • Closing your account too early: This decision could cause you to lose the benefit of an active, longer credit history (depending on the scoring model).

Bottom line.

A business line of credit has the potential to serve as both a flexible funding tool and a credit-building asset. So, prepare well, choose the right lender, borrow responsibly, and stay disciplined with payments to set your business up for the best chance of success. If you follow this path, you have a better chance of strengthening your company’s financial foundation and improving its credit profile at the same time.
