A business line of credit is one of the most flexible financial tools available to entrepreneurs, and also one of the most misunderstood. Some business owners treat it like a savings account they can dip into whenever cash runs low. Others are so afraid of debt they never tap it even when it makes perfect strategic sense. Neither approach is right.

This guide explains exactly what a business line of credit is, how it works, when you should use it, and when you shouldn’t.

What Is a Business Line of Credit?

A business line of credit is a revolving credit facility that gives your business access to a set amount of capital up to a predetermined limit. Unlike a term loan, where you receive a lump sum and make fixed payments over time, a line of credit works more like a credit card: you draw what you need, pay it back, and the credit becomes available again.

Key characteristics:

• Revolving: As you repay, your available credit resets. Draw $10K from a $50K line, repay it, and you’re back to $50K available.
• Interest on what you use: You only pay interest on the amount you’ve drawn, not on the full credit limit.
• Flexible deployment: Unlike a term loan tied to a specific purpose, a line of credit can fund almost anything: payroll, inventory, marketing, equipment, bridge gaps.
• Typically shorter terms: Lines of credit are usually reviewed and renewed annually, unlike multi-year term loans.

Secured vs. Unsecured Lines of Credit

Business lines of credit come in two main forms:

Secured

A secured line requires collateral: accounts receivable, inventory, real estate, or equipment. Lenders take less risk, so they offer lower interest rates and higher credit limits. Suitable for established businesses with assets to pledge.

Unsecured

No collateral required, but lenders compensate for the added risk with higher interest rates and lower credit limits. Qualification depends more heavily on your personal credit score, business revenue, and time in business. Most accessible for businesses in their first few years.

Where to Get a Business Line of Credit

Options include:

• Traditional banks: Lowest rates but strictest requirements. You’ll generally need 2+ years in business and solid revenue. Chase, Bank of America, and Wells Fargo all offer business lines of credit.
• Online lenders: More accessible, faster approval, but higher rates. Bluevine, Ondeck, and Kabbage (American Express) are common options for startups.
• Credit unions: Often competitive rates and more flexible underwriting than major banks.
• SBA lines of credit: The SBA CAPLines program offers government-backed lines for qualified businesses. Lower rates and better terms, but more paperwork. Our SBA loans guide covers the full landscape of government-backed financing options.

When You Should Use a Business Line of Credit

Managing Seasonal Cash Flow

If your business has predictable revenue cycles (retail spikes during holidays, service businesses that slow in summer), a line of credit bridges the gap. Draw during slow periods to cover payroll and operating costs, then repay when revenue picks up. This is the most classic and appropriate use of a line of credit.

Covering Short-Term Gaps Between Invoices

B2B businesses often face the problem of net-30 or net-60 payment terms. You’ve delivered the work, but payment isn’t coming for 30 to 60 days, and you have expenses due now. A line of credit covers that gap without disrupting operations.

Seizing a Time-Sensitive Opportunity

A supplier offers a bulk discount, a competitor is selling inventory at a discount, or a marketing opportunity has a deadline. If you have the cash flow to service the debt, drawing on your line of credit to capture time-sensitive upside is a smart use of leverage.

Managing Unexpected Expenses

Equipment breaks. A key contractor goes down sick. A client does a surprise chargeback. Having a line of credit as an emergency buffer means these events don’t derail your operation.

When You Should NOT Use a Business Line of Credit

Funding Operating Losses

If your business is consistently spending more than it earns and you’re drawing on a line of credit to cover that gap, you’re borrowing to survive. A line of credit doesn’t fix a broken unit economics problem. It delays the reckoning and adds interest charges on top. If this is your situation, you need to fix the business model before adding debt.

Long-Term Capital Purchases

Buying equipment, a vehicle, or commercial property with a line of credit mismatches the financing instrument to the asset. Use a term loan for assets with a multi-year lifespan. Using a short-term revolving credit facility for a long-term asset creates repayment pressure and ties up your credit availability.

Personal Expenses

Business credit is for business. Using a business line of credit for personal expenses creates accounting nightmares, potential tax issues, and erodes the legal separation between you and your business entity. This is especially important if you’ve structured as an LLC. Read our guide on how to separate personal and business finances for the full picture.

How to Qualify for a Business Line of Credit

Lenders evaluate several factors:

• Time in business: Most require 6 to 12 months minimum; traditional banks prefer 2+ years
• Revenue: Typically $100K to $250K annual revenue for online lenders; higher for banks
• Personal credit score: 600+ for most online lenders, 680+ for traditional banks
• Business credit score: Dun and Bradstreet, Equifax Business, and Experian Business scores all matter
• Cash flow: Lenders want to see that revenue exceeds expenses reliably

Build the Relationship Before You Need It

The best time to apply for a line of credit is when you don’t need it. Lenders are more comfortable extending credit to businesses with healthy cash flow and no urgency. Applying in a crisis, when cash is tight and desperation shows in your numbers, is the hardest time to get approved and the worst time to negotiate terms.

Open the relationship early. If you bank with Chase or another traditional institution, have the conversation with your business banker when your business is performing well. Establish the line before you need it. Then it’s available when opportunity or adversity arrives.

The Bottom Line

A business line of credit is a powerful tool for managing cash flow, capturing opportunity, and building financial resilience. Used correctly, it’s a competitive advantage. Used incorrectly, it accelerates financial decline.

Know the difference. Use it for short-term needs with predictable repayment paths. Build the relationship before you need it. And make sure your business fundamentals are strong enough that borrowing is an amplifier, not a lifeline.
