A business line of credit is one of the most useful financial tools a small business can have — and one of the most commonly misunderstood. Many business owners apply when they desperately need cash and get rejected. The businesses that have lines of credit when they need them are the ones that applied when they didn’t need them yet.

Here’s how business lines of credit actually work, what lenders want to see, and how to get one.

What a Business Line of Credit Is

A business line of credit is a revolving credit facility — a pool of available capital you can draw from as needed, repay, and draw again. Unlike a term loan (where you borrow a fixed amount and repay on a schedule), a line of credit is flexible. You borrow what you need, when you need it, and only pay interest on the amount you’ve actually drawn.

Example: You have a $75,000 line of credit. You draw $20,000 to cover a slow month. You repay $10,000 next month. Your available balance goes back to $65,000. You draw again if needed. The line stays open as long as you maintain it in good standing.

This makes lines of credit ideal for managing cash flow gaps — seasonal businesses, businesses with 30/60/90-day payment cycles, businesses that need to pay vendors before collecting from clients.

Secured vs. Unsecured Business Lines of Credit

Unsecured Lines of Credit

No collateral required — the lender extends credit based on your creditworthiness alone. These carry higher interest rates than secured lines, come with lower credit limits for newer businesses, and require stronger credit profiles to qualify. For businesses with excellent credit history, this is the most flexible option.

Secured Lines of Credit

Backed by collateral — typically accounts receivable, inventory, equipment, or real estate. Secured lines offer higher limits and lower rates because the lender has recourse beyond your promise to pay. Asset-based lending (ABL) is a specific secured LOC structure where the credit limit is tied to a percentage of eligible receivables or inventory (typically 70–85% of eligible AR, 40–60% of inventory).

What Lenders Actually Look For

Time in Business

Most traditional banks want 2+ years in business for a line of credit. Online lenders often start at 6–12 months. Startups with no operating history are essentially limited to secured options, credit cards, or finding lenders that specifically serve early-stage businesses.

Annual Revenue

Lenders size the line relative to your revenue. A common rule of thumb: lines of credit are available up to 10–20% of annual revenue. A business with $500,000 annual revenue is more likely to qualify for a $50,000–$75,000 line than a $200,000 line. Some online lenders go higher, particularly for businesses with strong AR.

Personal Credit Score

For small business lines of credit, personal credit matters significantly — especially for businesses with limited business credit history. Most banks want 670+ minimum; strong lenders prefer 700+. Online lenders may accept 580–650 but at significantly higher rates.

Business Credit Profile

A strong business credit profile (good PAYDEX, Intelliscore, Equifax Business scores) can supplement personal credit and may allow lower rates or higher limits. This is a compounding argument for building business credit early — the businesses with strong profiles get better terms on everything.

Cash Flow and Bank Statements

Lenders review your bank statements (typically 3–6 months) to assess average daily balance, revenue flow, and whether the account is consistently in positive territory. Accounts with frequent overdrafts or very low average balances signal cash flow problems that work against approval.

Profitability

Not all lenders require profitability, but it helps. If your business is pre-profit or showing net losses on tax returns, you’ll need to show a clear path to profitability or work with lenders that underwrite differently (revenue-based, AR-based).

Best Sources for Business Lines of Credit

Traditional Banks

Your primary business bank is often the best starting point. Banks prefer lending to existing customers with a deposit relationship because they have direct visibility into your cash flow. A 2-year-old business with a solid banking relationship can often access a line at 8–12% APR from their bank — much better than alternative lenders.

Banks like Wells Fargo, Bank of America, and Chase all offer business lines of credit with established qualification criteria.

Credit Unions

Often more flexible on qualification and lower rates than commercial banks for similarly sized loans. If you’re a member of a credit union with business services, it’s worth an inquiry.

Online Lenders

• Bluevine: Lines up to $250,000, 6+ months in business, $10,000/month minimum revenue. Faster approval than banks.
• Fundbox: Lines up to $150,000, connects to your accounting software to assess cash flow. Approvals in hours.
• OnDeck: Lines up to $100,000 for established businesses. Higher rates than banks but accessible for businesses that don’t qualify for bank lines.

Online lenders charge more than banks but have faster approvals, lower minimum revenue requirements, and more flexibility on credit score minimums. Trade-off: rates typically run 15–50% APR vs. 7–15% at banks.

How to Use a Business Line of Credit Strategically

Lines of credit are most powerful as a bridge — covering short-term cash gaps while receivables are outstanding, taking advantage of inventory purchasing opportunities, or managing seasonal working capital needs. Using a line of credit to cover operating losses from an unprofitable business is a path to a debt spiral.

Keep Your Utilization Below 30%

Just like personal credit cards, high utilization on a business line of credit signals cash flow dependency and can affect your business credit scores. Drawing 70–80% of your line regularly makes lenders nervous. Keep utilization moderate — draw what you need, repay quickly, and maintain headroom.

Draw and Repay Regularly

An unused line that sits untouched for 12 months may be reduced or canceled by the lender. Making small, deliberate draws and repayments — even when you don’t strictly need to — demonstrates active, responsible use and keeps the relationship with the lender healthy.

Apply Before You Need It

This is the cardinal rule. Apply when your finances look strong — revenue is up, bank statements are healthy, personal credit is in good shape. Apply with adequate runway, not when you’re 30 days from a cash crisis. Lenders can smell desperation, and applications filed under financial stress rarely result in the best terms.
