What Is A Business Line Of Credit is one of the most searched funding questions for a reason: a line of credit can be a flexible safety net for cash flow gaps, seasonal swings, and short-term opportunities. But it’s also commonly misunderstood. Many business owners assume a line of credit works like a term loan (one lump-sum deposit with a fixed payment), when it’s closer to a reusable pool of funds you can draw from as needed.
In this guide, I’ll walk you through what a business line of credit is, how it works in plain English, what it typically costs, and how to decide if it’s the right tool for your business. I’ll also compare a line of credit to term loans and SBA loans, share a quick checklist for qualifying, and highlight common mistakes that make approvals harder than they need to be.
What is a business line of credit?
A business line of credit (LOC) is a revolving credit account that gives your business access to a maximum credit limit (for example, \$50,000). You can draw funds when you need them, repay what you borrowed, and then borrow again—similar to how a credit card works, but usually with different terms and higher limits.
The defining features are:
- Revolving access: Your available credit replenishes as you repay.
- Pay for what you use: Interest is generally charged only on the amount you draw, not the full limit.
- Flexible use of funds: Often used for working capital needs like inventory, payroll, and short-term operating expenses.
How a business line of credit works (step-by-step)
1) You’re approved for a credit limit
A lender approves your business for a maximum amount you can access—your credit limit. Depending on the lender and product, the limit might be as low as \$10,000 or as high as several hundred thousand dollars (or more for larger businesses).
2) You draw funds when needed
You can pull money from the line in one or multiple draws. Some lenders transfer funds to your bank account, while others give you a card tied to the line.
3) You repay what you borrowed (plus interest)
Repayment is typically weekly or monthly, depending on the lender. Once you repay, that amount becomes available to borrow again.
4) The line renews or is re-evaluated
Many lines of credit have a renewal date (often annually) where the lender reviews performance, financials, and credit to decide whether to keep the line open and at what limit.
Business line of credit vs. term loan vs. SBA loan (quick comparison)
Different funding tools solve different problems. Here’s a simple comparison to help you match the product to the need.
| Feature | Business Line of Credit | Term Loan | SBA 7(a) Working Capital Loan |
|---|---|---|---|
| How you receive funds | Draw as needed up to a limit | One lump sum | One lump sum |
| Interest charged on | Amount drawn | Full loan balance | Full loan balance |
| Best for | Cash-flow gaps, inventory, short-term needs | Projects, equipment, expansion, refinancing eligible debt | Longer-term working capital with SBA structure |
| Typical speed | Fast to moderate | Fast to moderate | Slower (more documentation) |
| Example ranges | SmartBiz business line of credit: \$50K–\$100K (6+ months in business required) | SmartBiz non-SBA term loans: \$30K–\$200K, starting at 8.99%, 2–5 year terms | SmartBiz SBA 7(a) working capital: \$50K–\$350K, Prime + 3%–5.75% (about 9.75%–12.50%), 10-year term |

When a business line of credit makes sense
A line of credit is usually a good fit when your need is real—but not perfectly predictable. Common use cases include:
- Seasonal inventory purchases (buy ahead of peak season, repay as sales come in)
- Bridging receivables when invoices are net-30/net-60
- Payroll timing gaps (especially for service businesses)
- Marketing tests with quick feedback cycles
- Emergency buffer for surprises like equipment repairs
Tip: Treat a line of credit like a tool, not income. The healthiest use is borrowing for something that creates or protects cash flow—then repaying quickly.
Typical rates, fees, and terms to expect
Interest rates
Rates vary widely based on credit, time in business, revenue, and whether the line is secured. Some lenders quote APR; others quote factor rates or simple interest equivalents. Ask for an apples-to-apples comparison using APR when possible.
Fees
Common fees may include:
- Origination fee (one-time)
- Maintenance or annual fee
- Draw fee (per withdrawal)
- Late payment fee
Repayment structure
Some lines require interest-only payments during a draw period, then principal repayment later. Others amortize each draw over a set schedule. Read the fine print: your payment can change depending on how the lender structures draws.
Secured vs. unsecured business lines of credit
Unsecured lines
An unsecured line of credit doesn’t require specific collateral (like equipment or real estate) to back the line. Approval often depends more heavily on credit profile and cash flow. Many unsecured lines still include a personal guarantee, meaning the owner is personally responsible if the business can’t repay.
Secured lines
A secured line of credit is backed by collateral—commonly accounts receivable, inventory, or other business assets. Secured lines can offer higher limits or better pricing for some borrowers because the lender has a stronger claim if the loan goes into default.
How to qualify for a business line of credit
Underwriting varies by lender, but most decisions come down to a few themes:
- Time in business: Many lenders prefer at least 6–12 months; some prefer 2+ years.
- Revenue and cash flow: Bank statements and/or financials should show consistent deposits and the ability to service payments.
- Credit profile: Both personal and business credit can matter.
- Banking behavior: Frequent overdrafts and negative days can hurt approvals.

Documents you’ll likely need (and how to prepare them)
Having documents ready can speed up decisions and reduce back-and-forth. Common requests include:
- Last 3–6 months of business bank statements
- Driver’s license and basic owner information
- Business legal name, EIN, and address
- Financial statements (profit & loss, balance sheet) for established businesses
- Tax returns (sometimes) depending on product and lender

Common mistakes to avoid
- Only shopping on rate: Fees, payment frequency, and draw rules can matter just as much as APR.
- Borrowing for long-term assets: Using a short-term line for equipment or buildouts can strain cash flow.
- Maxing out the line and leaving it: High utilization can hurt future increases and renewals.
- Not understanding repayment: Some products amortize each draw quickly, which can surprise borrowers.
FAQ: Business line of credit
Does a business line of credit build business credit?
It can, depending on whether the lender reports payments to business credit bureaus. If building business credit is a priority, ask the lender directly what they report and to whom.
What’s the difference between a business credit card and a line of credit?
Credit cards are designed for purchases and often come with rewards, while lines of credit are designed for cash access and working capital. Some business owners use both: a card for day-to-day spend and a line of credit as a flexible cash buffer.
Is a line of credit better than a term loan?
Neither is “better” universally. A line of credit is usually better for variable, short-term needs; a term loan is often better for a defined project or investment with a clear payoff timeline.
How much line of credit can I get for my business?
Limits depend on revenue, profitability, time in business, and credit. Some products are smaller and faster; others can be larger but require more documentation. As a reference point, SmartBiz offers business lines of credit in the \$50K–\$100K range for businesses with 6+ months in business.
